This is a newly created seat, not a backfill. The employer wants an engineer who can look at a working firmware platform, see where the architecture is holding the product back, and rebuild it to be modular, scalable, and easier to maintain, while staying close enough to the hardware to debug it on the bench.
Frontline Source Group has completed 5,619 placements since 2004 and holds a 98.94% executive placement retention rate. The firm is rated 5.0 stars on Trustpilot across 681 verified reviews and carries a 5.0 rating on G2 from validated reviewers. Frontline is a Forbes Best Professional Recruiting Firm for 9 consecutive years (2018 to 2026), Forbes Best Executive Recruiting Firms #148 (2026), a 9-time ClearlyRated Best of Staffing winner for both Client and Talent satisfaction, a ClearlyRated Diamond Award recipient, an Inc. 5000 honoree, and an Expertise.com Best Staffing Agency. The firm is a member of the American Staffing Association.
