Sensors Systems Engineer

Sensor Systems Engineer

Apex is looking for a Sensor Systems Engineer to own our sensor products across the full development lifecycle, from clean-sheet concept to qualified, production-ready hardware. This role sits at the intersection of design, analysis, test, and production, acting as the technical authority that carries a sensor from architecture through qualification and into the field. You'll own how our sensors perform in the real world, driving trade studies that balance performance, cost, and risk, leading verification and qualification campaigns, and closing the loop through failure investigations that sharpen every future design.

Responsibilities:

• Own sensor products through the full development lifecycle, including conceptualization, architecture, design, analysis, prototyping, qualification, and production
• Support production as the hardware Responsible Engineering Authority (REA), providing technical solutions, guidance, and documentation when issues arise
• Manage project budget, schedule, and tasking within a multidisciplinary team of engineers

• Own verification and validation activities for sensor subsystem requirements
• Develop and execute qualification and test campaigns, including creation of test plans, procedures, and reports. Collaborate with cross-functional teams to develop and maintain test stations and ground support equipment (GSE/STE)
• Perform failure investigations and root cause analyses, incorporating lessons learned into future designs and test approaches

• Perform system- and component-level trade studies to evaluate architectures and designs to optimize performance, cost, schedule, and technical risk
• Collaborate with teams across structures, thermal, optics, avionics, software, GNC, manufacturing, mission assurance, and supply chain to develop integrated sensor solutions
• Present technical work at design reviews and create clear, thorough engineering documentation

Required Qualifications:

• Bachelor's degree in Aerospace Engineering, Systems Engineering, Electrical Engineering, Mechanical Engineering, Computer Engineering, Software Engineering, Applied Physics, or a related discipline
• Hands-on experience developing, prototyping, integrating, and/or testing multidisciplinary systems
• Demonstrated hardware, project, or product ownership experience
• Strong understanding of test engineering fundamentals and methodologies
• Demonstrated leadership, time management, and organizational skills
• Comfortable researching and creating clean-sheet subsystem architectures and designs within an open design space
• Self-motivated and eager to learn in a fast-paced, collaborative engineering environment

Preferred Qualifications:

• 1-2 years of experience in aerospace, automotive, or other technical product development/test
• Master's degree in Aerospace Engineering, Systems Engineering, Electrical Engineering, Mechanical Engineering, Computer Engineering, Software Engineering, Applied Physics, or a related discipline
• Experience developing, designing, implementing, and/or testing sensor systems
• Familiarity with Design for Manufacturing (DFM/DFMA) principles
• Familiarity with satellite systems and space environments
• Familiarity with all stages of the hardware product lifecycle
• Familiarity with project management tools and techniques
