Senior Embedded Software Engineer

Job Title

Senior Embedded Software Engineer

This is a contract‑to‑hire opportunity, with the intent to convert to a direct hire role. The contract period is typically expected to run approximately 6 to 12 months before conversion, depending on individual performance, business needs, and internal timing. Unlike a standard contract role where conversion may only be a possibility, the plan for this position is for the selected candidate to transition into a permanent role, assuming strong performance and continued mutual fit.

This role supports a major defense contractor and requires candidates to be U.S. Citizens due to the nature of the work and the requirement to be eligible to obtain a U.S. Secret security clearance. An active clearance is not required to start; however, candidates must meet U.S. citizenship requirements for future clearance eligibility. Permanent Residents/Green Card holders and candidates who require or currently hold work authorization through F1‑CPT, F1‑OPT, H‑1B, TN, or other temporary visa classifications are not eligible for this role.

Due to federal contractor requirements, offers may be contingent upon successfully completing a background check and drug screening, which may include testing for cannabis. There are no exceptions to this requirement, including for medical marijuana cardholders.
