Non Exempt Avionics Test Station Jobs (NOW HIRING)

Spacecraft represent the most pressing unmet need across the entire aerospace industry. As more launch vehicles come online and the cost to orbit decreases, more companies launching payloads to space continue to emerge.For the first time in history, this influx of payload companies combined with reduced launch costs has resulted in a massive increase in need for commercial spacecraft platforms, known as satellite buses. These buses hold the payloads of our customers and are flown on launch vehicles.Apex manufactures these satellite buses at scale using a combination of software, vertical integration, and hardware that is designed for manufacturing. Our spacecraft enable the future of society: ranging from earth observation to communications and more.We’d love for you to join us on our mission of providing humankind access to the galaxy beyond our planet.

We’re looking for a Hardware Test Engineer to join our growing avionics test team. In this role, you’ll focus on hardware integration and testing, system-level and component-level test rack planning and buildup, avionics validation, and automated spacecraft test execution. You’ll work closely with electrical, mechanical, RF, and systems engineers to build and operate integrated spacecraft test environments, execute qualification campaigns, and troubleshoot flight hardware throughout development and integration. This role is highly hands-on and ideal for engineers who are ready to lead technical work independently, enjoy working directly with flight hardware and integrated test environments, and want to grow your impact beyond individual execution.

• Own the build, configuration, and maintenance of bus-level and/or component-level test racks
• Lead hardware integration activities including harnessing, fixturing, rack integration, and mechanical/electrical interface validation
• Own troubleshooting of flight hardware and test setup failures using laboratory instrumentation including oscilloscopes, multimeters, power supplies, DAQ systems, VNAs, and vector signal analyzers/generators
• Support Flatsat operation and maintenance activities as needed
• Execute and document functional checkouts, acceptance testing, environmental screening, and integrated system validation
• Support environmental and qualification campaigns including EMI/EMC, vibration, thermal cycling, and TVAC
• Execute RF and avionics validation testing for antennas, radios and transceivers, GNSS systems, LNAs and PAs, RF switches, and couplers and power dividers
• Perform near-field antenna testing, cable loss characterization, S-parameter measurements, and insertion loss analysis
• Support RF testing in thermal vacuum environments, including understanding of corona and multipactor considerations
• Own test setup documentation including test setup diagrams, bills of materials (BOMs), harnessing documentation, and configuration records for component- and bus-level test racks
• Author and maintain Design Verification Plans (DVPs), procedures, and test documentation

• Own medium cross-functional or large function-specific avionics test projects end-to-end, from planning through closeout
• Execute to an agreed plan, proactively identifying risks and resolving blockers
• Coordinate partner teams across electrical, mechanical, RF, and systems engineering to keep integration and test campaigns on track
• Provide structured updates and input at key project milestones, communicating status clearly to both technical and non-technical stakeholders
• Collaborate with cross-functional teams on design-for-test initiatives and spacecraft integration campaigns

• Informally mentor and develop junior engineers on technical skills, test practices, and hardware integration workflows
• Review junior engineer work products such as test procedures and documentation, providing constructive technical feedback

• Bachelor’s degree in Electrical Engineering, Aerospace Engineering, Physics, or related field
• 5+ years of professional experience in aerospace hardware or electronics testing
• Hands-on experience with laboratory instrumentation and hardware bring-up
• Familiarity with avionics hardware and embedded communication protocols: UART/SPICAN/I²C
• Experience troubleshooting integrated electrical systems and test setups
• Strong understanding of hardware integration and validation workflows
• Excellent problem-solving and communication skills
• Must be a U.S. Person (U.S. Citizen or Green Card holder) in accordance with ITAR requirements

• Experience integrating or testing spacecraft, launch vehicles, or flight electronics
• Familiarity with RF communications systems and RF lab equipment
• Experience with: Harnessing, Fixturing, Environmental testing, Vibration testing
• Familiarity with coaxial cable selection and RF interconnect characterization
• Exposure to fast-paced aerospace production or integration environments
• Experience designing PCBs or supporting hardware prototyping
• Background conducting sensor functional tests, leak checks, or avionics channelization
• Basic Python or scripting experience for test support and automation
