FPGA Engineer

We’re seeking engineers who thrive on solving hard problems and turning bold ideas into real-world solutions. If you’re driven to design, develop, and test technology that truly makes an impact, you’ll feel at home here.

Quest Defense Systems and Solutions is actively hiring FPGA Engineers to design and verify digital logic solutions for major FPGA platforms including Xilinx, Altera, and Microsemi. Work spans the full development lifecycle — requirements definition, architecture, VHDL coding, simulation, integration, debug, documentation, and support through production. Applications include gigabit serial interfaces, RF/EO DSP, controls, embedded processing, and processor interfaces.

Engineers collaborate with circuit card designers and systems engineers through every stage of development.

We are hiring FPGA Engineers at various levels!

Location:

Onsite Tucson, AZ.  Relocation assistance is available

Citizenship:

Due to the nature of the work, US Citizenship is required.

Clearance:

Active DoD Security Clearance

What you will be doing:

• Architect FPGA‑based systems, determining interfaces, device selection, and concept of operations (CONOPS).
• Translate system‑level requirements into FPGA requirements.
• Design and code FPGA implementations in VHDL with emphasis on reliability and maintainability.
• Perform simulation, place‑and‑route, and verification using both directed tests and constrained‑random techniques.
• Track functional and code coverage during verification.
• Integrate and debug designs in lab environments.
• Deliver production‑quality FPGA releases from prototype through full production.
• Create detailed documentation: requirements, verification plans, user guides.
• Support internal and external technical reviews.

Qualifications You Must Have:

• FPGA Engineer – Mid
