Data center recruiting is the hiring of the electricians, mechanical and controls technicians, and facilities staff who build a data center campus and then run the halls once the doors open. Joy, Classet's AI recruiter, phone-screens each applicant the moment the application lands, asks about state electrical license, medium-voltage and UPS experience, travel radius, and shift availability, and sends the recruiter a structured summary with the transcript and recording. A human on your team decides who moves forward. General contractors staffing a hyperscale build, MEP subcontractors bidding electrical and mechanical scopes, staffing firms placing data center trades, and colocation operators filling 24/7 facilities technician shifts use Joy for the first conversation. The market is short of people at both ends. According to Kelly's 2026 Data Center Salary Guide, 90% of data center operators call staffing shortages a critical constraint on building or expanding, and 25% of data center personnel are hired away by competing operators each year. ## Results data center employers can expect 88% of candidates who start the phone screen finish within 20 minutes of applying Classet: Classet platform data, completed interviews across customer accounts 55% of applicants apply outside business hours Classet: Classet platform data, completed interviews across customer accounts 88% of candidates rate the interview positively (10,167 ratings) Classet: Classet candidate feedback, 10,167 post-interview ratings on a 4-point scale $30.38 median hourly wage, electricians, May 2025 [U.S. Bureau of Labor Statistics: Occupational Employment and Wage Statistics, May 2025: electricians (47-2111)](https://www.bls.gov/oes/current/oes472111.htm) The first three figures are Classet platform data; the fourth is the wage floor a data center recruiter is bidding above. ![Cox-Powell HVAC logo](/_next/image?url=%2Fcustomer-logos%2Fcox-powell.jpg&w=256&q=75)skilled-trades > This has been a fantastic partnership.

About one in six Associated Builders and Contractors members was under contract on data center work in August 2026, and those contractors reported a 9.9-month backlog against 8.3 months for the rest, according to ENR. Electricians are the largest trade on a build. The Bureau of Labor Statistics counted 757,220 electricians in May 2025 at a median of $63,190 a year, or $30.38 an hour, and projects 9% growth to 2035 with about 72,700 openings a year. One Loudoun County, Virginia crew profiled by Data Center Frontier in November 2024 ran more than 250 electricians and 60 to 70 apprentices under one Power Solutions general foreman. Recruiting firm Data Center TALNT puts the industry average at 126 days to fill a data center construction role, against a median of 10 days from client interview to offer in a TALNT search. ## What Joy asks a data center electrician or technician applicant Joy is the AI recruiter Classet runs on a data center application, and the call starts the moment the application lands, at 11pm on a Saturday or 5am before a shift starts. 1. The applicant applies through your ATS, a job board connected to Hiring Hub, or a shareable interview link, and Joy calls, with a text and email follow-up if the call is missed. 2. Joy asks the questions you wrote for the role. For a data center electrician the list covers state electrical license and class (journeyman or master), OSHA 10 or OSHA 30, NFPA 70E training, medium-voltage work at 15 to 35 kV, UPS and battery systems, generator paralleling switchgear, commissioning and load-bank testing, travel radius, per diem, relocation for a ramp, and availability for 12-hour rotations. 3. Joy runs the interview in the applicant's language, one of 25+, and delivers the transcript in the language your team reads. Applicants who prefer a person can opt out. ## What your team receives after the interview The interview summary is a one-page record of the applicant's answers, delivered with the full transcript and the call recording for each completed interview. ATS Sync files all three on the candidate record in Greenhouse, Workday, Lever, Bullhorn, iCIMS, or another of the 95+ applicant tracking systems Classet connects to; Hiring Hub holds the same record with nothing to integrate. Knockout results sit at the top and show which must-have criteria the applicant meets, for example a current state journeyman license and 24 months on medium-voltage switchgear. Knockout results route candidates to the stage you set, so an applicant without the license lands in a review column. Each must-have comes back Met or Not met, and Fast-track, if you turn it on, flags the strongest fits for a first call; nobody is moved or turned away by software, and your recruiter can disagree with any result. A recruiter at a GC or MEP sub reads the summary in about a minute, plays the recording when needed, and decides who gets the site interview. Candidates who clear your must-haves can get a text with your open times and book on their phone through [Scheduling](/scheduling), available by request. [Call to Apply](/call-to-apply) adds a hiring number on the truck or sign that Joy answers 24/7. Across Classet accounts, 88% of candidates who start the phone screen finish within 20 minutes of applying. ## How Cox-Powell hires with Joy Cox-Powell HVAC is a mechanical contractor whose service operations manager, JD, has not hired a technician through any other channel since the company moved first-round screening to Joy. Technicians apply after the shift, Joy interviews the applicant the moment the application lands, and the service operations team reads summaries and recordings instead of returning voicemails. The same setup carries over to data center mechanical and controls work. The questions change to chilled-water plant, CRAH and CRAC units, and BMS experience, the knockouts change to EPA 608 and NFPA 70E, and the first-call timing stays the same. Across Classet accounts, 55% of applicants apply outside business hours, which for a tradesperson means after the shift, from the truck, or on a Sunday. ## Roles Joy screens on data center sites Joy screens four role groups on data center builds and in live facilities, each with its own knockouts. Construction electricians are asked for state license and class, NFPA 70E, OSHA 10 or 30, medium-voltage experience at 15 to 35 kV, travel radius, and per diem expectations. Pipefitters and mechanical technicians cover chilled-water plant work, welding and brazing certifications, and CRAH and CRAC installs. Controls and BMS technicians are asked which platforms the applicant has programmed, for example Siemens, Johnson Controls, or Schneider Electric. Facilities and critical-environment technicians, who run the hall once the campus is live, are asked about 12-hour rotations, on-call willingness, and time in a live critical environment. Uptime Institute recommends a minimum of one to two qualified operators on site 24 hours a day, 7 days a week, so a single hall carries a standing roster for the role. According to Kelly's 2026 Data Center Salary Guide, 25% of data center personnel are hired away each year. See Joy interview a data centers applicant Your first 20 completed interviews are free.

Joy (Classet) Manual phone screens General ATS When the first interview happens The moment they apply, 24/7 When a recruiter gets to the list, during business hours Not at all: the application waits in a queue until someone reviews it Applicants who apply after hours (55% across Classet accounts) Interviewed the same night Called back the next business day, often later Seen whenever someone next logs in What your team receives Structured summary, transcript, recording and knockout results The recruiter's notes, if they took any A resume and the application answers Recruiter time per applicant Reading a summary; playing the recording when needed Dialing, voicemail, phone tag and the call itself Reading resumes, then a phone screen anyway Who decides who gets hired Your team Your team Your team Cost Standalone from $249/month (annual), ATS-integrated from $1,995/month Recruiter hours ATS subscription, plus recruiter hours to screen ## Frequently asked questions ### How do I hire data center electricians faster? The fastest way to hire data center electricians is to cut the time between the application and the first real conversation to the same hour. Data center electricians apply from job sites and after shifts, then take the first credible offer. Joy calls the applicant the moment the application lands, asks about the state license, medium-voltage and UPS experience, and travel availability, and puts a summary in front of your recruiter the same hour. Across Classet accounts, 88% of candidates who start the phone screen finish within 20 minutes of applying, so your team is calling back a screened electrician while other bidders are still reading resumes. The scale of the competition is the reason the hour matters: the Bureau of Labor Statistics projects about 72,700 electrician openings a year from 2025 to 2035, and recruiting firm Data Center TALNT puts the industry average at 126 days to fill a data center construction role. ### How does Joy screen for medium-voltage or mission-critical experience? Joy screens for medium-voltage and mission-critical experience by asking about the specific equipment and voltage classes you name, in conversation. A typical data center electrician screen covers voltage classes worked (usually 15 to 35 kV on campus distribution), UPS and battery systems, generator paralleling switchgear, commissioning and load-bank testing, and time in a live critical environment, plus NFPA 70E and OSHA 30 status. When an applicant names specific equipment, for example a Cummins paralleling gear or a Vertiv UPS, Joy follows up on the years and the role. The answers land in a structured summary with the recording attached, and your team decides who moves forward; a recruiter can disagree with any Fast-track flag. [Candidate insights](/candidate-insights) turns the structured answers from your interviews into data your team can act on, such as the pay candidates expect and which requirements they miss most. Kelly's 2026 Data Center Salary Guide found 88% of employers reporting high demand for medium-voltage electrical expertise, which is why the question belongs on the first call instead of the site interview. ### Can Joy staff 24/7 operations shifts? Yes, Joy is built for 24/7 facilities hiring because the interview runs at any hour, so a facilities technician coming off nights can finish the screen at 7am. Joy asks about shift preferences, 12-hour rotation experience, commute distance, and on-call willingness, and knockouts route applicants who cannot cover the shift to a separate stage. The roster math is why the volume matters. Uptime Institute recommends a minimum of one to two qualified operators on site 24 hours a day, 7 days a week, 365 days a year, and Kelly's 2026 Data Center Salary Guide found 25% of data center personnel are hired away by competing operators each year. A facility that fills the roster in the first quarter is recruiting again by the fourth, and 55% of applicants across Classet accounts apply outside business hours, which for a night-shift technician is the only time available. ### How does this compare to a data center staffing agency? A data center staffing agency sources candidates for you and charges for each placement, while Joy screens the applicants who already come to you for a flat monthly plan. According to The Resource Company's 2026 staffing markup report, agencies bill a 30% to 75% markup on each hour a temporary or contract worker bills, or a direct-hire fee of 15% to 30% of first-year pay, and the same candidate is often presented to the other bidders on your job. Joy interviews the applicant the moment the application lands, files the summary in your ATS or Hiring Hub, and you keep the pipeline. Many contractors run both. Joy handles applicant flow while the agency hunts for the commissioning lead nobody has applied to yet. The [full comparison](/compare/data-center-staffing-agency) has the cost breakdown, and Starter plans start at $249 a month billed annually. ### Which ATS does Joy write to? ATS Sync connects Classet to 95+ applicant tracking systems, including Greenhouse, Workday, Lever, Bullhorn, iCIMS, UKG, and SAP SuccessFactors. Summaries, recordings, transcripts, and knockout results appear on the candidate record, so nobody re-keys a phone screen from an email, and the electricians screened for the last hall are already on your requisitions when the next one opens. Teams without an ATS use Hiring Hub, Classet's built-in candidate management, which includes a direct Indeed connection, candidate import, and Kanban pipeline boards. A full ATS Sync integration goes live in one to two weeks, longer for Workday and Dayforce and starts at $1,995 a month, scoped in a discovery call. The current list of the 95+ systems is at [/integrations](/integrations), and a GC running several subs on one campus can trigger Joy from a stage in each sub's pipeline. ### How do I staff a data center construction project? Staffing a data center construction project is a matter of planning the headcount curve by phase and making the first conversation with each applicant happen the day the application lands. A build runs civil and structural first, then MEP rough-in, where electrician headcount on a hyperscale campus peaks in the hundreds, then commissioning, when the controls and testing specialists arrive. One Loudoun County crew profiled by Data Center Frontier ran more than 250 electricians under a single general foreman during that peak. Open requisitions a phase ahead and keep a bench warm between phases. Joy handles the first screen for GCs and MEP subs, capturing license, medium-voltage experience, travel, and per diem on the first call, and an agency fills the gaps. Data Center TALNT puts the industry average at 126 days to fill a role, so a GC that screens the same day has a four-month head start on the next bidder. ### How fast can a general contractor be live before a ramp? A general contractor is live the same day on Starter or Scale. Paste the job description, Joy drafts the screening questions, and you share the interview link or connect a job board account; Joy starts calling applicants the same afternoon, and a 30-person opening and a 300-person ramp run at the same speed. A full ATS Sync integration goes live in one to two weeks, longer for Workday and Dayforce, inside the lead time of most MEP rough-in phases. Starter is $249 a month billed annually ($349 month-to-month) with 50 completed interviews included, and Scale is $999 a month billed annually ($1,399 month-to-month) with 250. Only completed interviews count, so a ramp with many unanswered calls is not billed for the attempts. ATS-integrated deployments start at $1,995 a month and are scoped in a discovery call based on volume and the number of campuses.
