Is the Data Engineer (Ab Initio) role on-site?

Yes — this role is on-site at the client's Wilmington, DE location, five days per week. The client's culture and delivery cadence are calibrated around in-person collaboration for this position. Relocation support may be available for the right candidate; the recruiter will confirm during your calibration call.

Is this a contract or full-time role?

This is a contract opportunity on ApTask's payroll. If selected, you will be employed by ApTask and will receive a W-2 for the duration of your assignment. During your engagement, you will be eligible for subsidized benefits, including medical, dental, vision insurance, a 401(k) plan, commuter benefits, and state-mandated paid sick leave. Your pay cycle (weekly or biweekly, as applicable) will be confirmed at the time of your offer. You'll also have a dedicated ApTask recruiter as your single point of contact throughout your assignment, providing ongoing support from onboarding through completion. Many of our contract opportunities are extended or converted to permanent positions based on business needs and performance. Your recruiter can share the client's historical extension and conversion trends during the interview process. Benefits, assignment duration, extension, conversion opportunities, and eligibility are subject to client requirements, business needs, and applicable plan terms.

What is the compensation range for this role?

The advertised range for this Data Engineer (Ab Initio) role is $60–$65 per hour. Where you land within the band depends on validated experience, the specific stack calibration match, and — for contract engagements — the bill-rate the client has locked in for this requisition. The recruiter will discuss the exact number during your calibration call.

How quickly does the interview process move?

If your profile is a fit for this role, you can expect the recruiter's first call within one business day. From there, interview cadence depends on the client's hiring-manager and panel availability. Total time from submission to signed offer varies by client — pre-verified profiles and calibrated submissions cut the noise, but the pace of interviews is driven by the client, not us.

What technical skills does the Data Engineer (Ab Initio) role require?

The client is targeting depth in Data. Adjacent experience is welcome — we routinely place candidates whose exact stack match is 60-70% when the underlying pattern (distributed systems, regulated-data handling, or comparable) is strong. Bring the full stack breadth to your calibration call; the recruiter will map it onto the client's evaluation scorecard.

About technology at ApTask

What this vertical looks like inside ApTask.

Technology roles at ApTask cover the software, cloud, data, security, and platform-engineering functions that power Fortune 500 digital operations. Our recruiters specialise in high-signal technical calibration — every candidate is validated against the specific stack, framework versions, and deployment context the client runs, not a keyword match. Our largest engagements sit inside AWS, Azure, GCP, Snowflake, Databricks, and modern data-mesh estates. Because we route through Fieldglass, Beeline, Workday VNDLY, and Coupa VMS, technology contractors placed through ApTask carry MBE diversity spend against the client's supplier program while remaining W-2 with full benefits under our payroll.

How it works

What happens after you apply.

1. Verified profile
Submit your résumé and complete the ApTask identity + skills verification. We check right-to-work, background, and technical calibration once — never resell or re-verify — so future roles surface faster.
2. Recruiter calibration call
Within one business day, the recruiter who owns this requisition reviews your profile against the client's specific stack, arrangement, and start-date requirements. You'll hear back either way — no ghosting.
3. Client interview
If your profile is a fit, we present you to the hiring team. Most clients run 2-3 interview stages: hiring-manager screen, technical panel, and final. We prep you with the exact scorecard criteria before each round.
4. Offer + onboarding
On acceptance, you onboard W-2 with ApTask (contract) or direct-hire with the client (per role type). Benefits, payroll, and timesheets run through us. Your recruiter stays your point of contact for the length of the engagement.
