Senior HITL Test Engineer

HITL Test Engineer

We are seeking a highly skilled and motivated HITL Test Engineer to join our rapidly-growing team. In this role, you will be responsible for designing, building, and maintaining the  hardware-in-the-loop (HITL) testbeds that serve as the primary proving ground for every satellite we build and fly. You will collaborate with nearly every engineering team — Flight Software, Guidance Navigation & Control, Avionics, Power, Payload, and Mission Ops — to ensure our testbeds are flight-representative, reliable, and always ready to support testing. If it runs on a satellite, it gets proven on HITL first.

Role

Own the full lifecycle of flatsat and HITL testbed builds, from initial design and BOM development through hardware procurement and software bring-up

Scope and design harnessing needs, coordinating with manufacturing to produce custom harnesses for flight-like hardware

Serve on a rotating on-call point of contact for testbed health, triaging anomalies and managing access for other engineers

Diagnose and resolve hardware and software failures on the testbed, spanning firmware interfaces, flight software, and physical components

Drive testbed architecture decisions, including hardware allocation tradeoffs and risk mitigation for testbed contention

Expand simulation capabilities as new satellite blocks come online, integrating motor emulators and deployment simulators

Develop tooling to improve testbed observability, monitoring, and automated operations

Assist in recruiting, interviewing, and hiring additional teammates to our rapidly-growing team

Requirements

Bachelors degree in EE, AE, CS (or equivalent background knowledge)

2-5+ years of experience in hardware integration, systems bring-up, or test engineering

Comfort working across hardware and software, from rack assembly to debugging Python tracebacks

Experience with embedded systems, EGSE, or laboratory hardware like logic analyzers and oscilloscopes

2+ years of experience with Python (or equivalent high-level scripting language) for test automation

1+ years of experience with Linux and shell command line tools

1+ years of experience with version control systems (git or equivalent)

Experience reading schematics and debugging circuits that interface with embedded software

Strong debugging instincts and a methodical approach to documenting novel failures

Excellent written and verbal communication skills

A passion for building things, including working in a fast-paced environment and hands-on development

Bonus

Familiarity with flight software architectures, telemetry systems, or simulation frameworks

Prior experience with networked lab infrastructure, Kubernetes, or Linux system administration

Please apply even if you do not meet every single criterion listed above
