Electrical Engineer III
Position Overview
OKSI is seeking an Electrical Engineer III to lead the design and deployment of ruggedized, mission-critical electronics for defense and environmental applications. You'll own hardware design from architecture through field validation on systems where reliability is uncompromising, collaborate cross-functionally, and mentor early-career engineers.
What You Will Do
- Lead design of complex electrical systems (mixed-signal PCBs, embedded controllers, sensor interfaces) for defense and environmental applications
- Architect low-power, high-reliability solutions for rugged, space-constrained platforms (guidance systems, UAS payloads, sensor packages)
- Define requirements and validate against functional, thermal, and EMI/EMC targets
- Integrate processors, FPGAs, sensors, and power subsystems; collaborate with software teams on hardware/firmware communication
- Own electrical design workstreams from requirements through production release
- Mentor junior engineers and interns with hands-on lab support
- Lead design reviews, trade studies, root cause analysis, and corrective actions
- Develop test procedures and lead lab validation (thermal, vibration, environmental testing)
- Maintain complete engineering documentation (schematics, BOMs, test data, compliance reports)
- Manage vendor collaboration on PCB fabrication, DFM, and component lifecycle
- Propose new components, tools, and methodologies to improve performance, cost, and reliability
Requirements
- Preferred Qualifications: Background in munition systems, guided weapons, drone/UAS, or robotics—domains where hardware reliability is mission-critical
- Experience in aerospace, defense electronics, hypersonics, or space systems
- Familiarity with guidance and navigation technologies, including inertial and magnetic sensors
- Experience with optics, EO/IR, and multispectral digital imaging systems
- MIL-STD or DO-160 EMC design and test experience
- Expertise in electronics design and testing for harsh environments (shock, vibration, thermal extremes)
- Knowledge of programmable logic design (FPGA/CPLD)
- Signal integrity and power integrity design skills
- Experience transitioning products from prototype into full production
- Low-level firmware expertise, particularly for hardware bring-up and testing
- Understanding of ITAR and export compliance requirements
- Active DoD security clearance or eligibility to obtain one
Work Location
Torrance, CA, 5 days/week on-site. Relocation assistance provided.
Compensation And Benefits
- $105,750 – $143,073 annually
- Medical, dental, vision fully paid
- 3 weeks vacation
- 5% automatic 401(k) contribution
- Professional development and relocation assistance
