Position Overview

OKSI is seeking an Electrical Engineer III to serve as a technical contributor and subsystem lead in the development of ruggedized, AI-integrated electronics for defense and environmental science applications. This role involves full ownership of hardware design efforts — including circuit architecture, embedded integration, testing, and field validation — while ensuring high reliability, compact form factors, and compliance with industry standards. This position requires close collaboration with cross-functional teams and includes mentoring early-career engineers and identifying opportunities for innovation and continuous improvement.

What You Will Do

• Lead the design and development of complex electrical systems, including mixed-signal PCBs, embedded controllers, and custom sensor interfaces
• Architect low-power, high-reliability solutions for rugged and space-constrained applications
• Define electrical system requirements and validate hardware against functional, thermal, and EMI/EMC targets
• Integrate embedded processors, FPGAs, sensors, and power subsystems within multifunctional platforms, working closely with software teams on hardware/firmware communication
• Own electrical design workstreams within multidisciplinary projects, from requirements through release
• Provide technical guidance and task leadership to junior engineers and interns, including hands-on, in-person support at the bench and in the lab
• Serve as a key contributor in design reviews, risk assessments, and trade studies
• Develop test procedures and lead lab validation efforts, including thermal, vibration, and environmental testing
• Conduct root cause analysis for design or deployment issues and implement corrective actions
• Maintain complete documentation for designs, including schematics, BOMs, test data, and compliance reports
• Collaborate with vendors on PCB fabrication, assembly, and design for manufacturability (DFM); assist in resolving production issues and managing obsolescence and lifecycle planning
• Evaluate and propose new components, tools, and methods to enhance performance, reduce cost, or improve manufacturability

What You Will Need

• Bachelor's degree in Electrical Engineering or equivalent
• 4–6 years of relevant working experience
• Strong working knowledge of low-power design, sensor integration, and signal conditioning
• Familiarity with compliance standards (e.g., MIL-STD-461, IPC-610, ISO, ITAR/EAR)
• Proficiency in lab testing, debugging, and root cause analysis using industry-standard tools
• Ability to manage engineering tasks independently and drive results across multiple stakeholders
• Excellent communication skills and a collaborative, solution-oriented mindset

Preferred Qualifications

• Background in automotive, EV, AV, aerospace, or space industries
• Familiarity with guidance and navigation technologies, inertial and magnetic sensors
• Experience with optics and multispectral digital imaging systems
• MIL-STD or DO-160 EMC design and test experience
• Expertise in electronics design and testing for harsh environments
• Knowledge of programmable logic design
• Skills in signal integrity and power integrity design
• Experience transitioning products into full production and shipping at scale
• Low-level firmware expertise, particularly for bring-up and testing

Compensation and Benefits

• Salary range: $105,750 – $143,073 annually. New hires are typically brought into the organization at a salary between the range minimum and the salary range midpoint depending on qualifications, internal equity, and the budget allocated for this role.
• Medical, dental, and vision coverage fully paid by the employer for employees
• Three weeks of vacation to start
• Automatic company contribution to 401K – 5% of earned wages (no matching required)
• Educational assistance and professional development opportunities
• This role requires being in-office (Torrance, CA)
