Avionics HITL & Test Technician

K2 is building the largest and highest-power satellites ever flown, unlocking performance levels previously out of reach across every orbit. Backed by $450M from leading investors including Altimeter Capital, Redpoint Ventures, T. Rowe Price, Lightspeed Venture Partners, Alpine Space Ventures, and others – with an additional $500M in signed contracts across commercial and US government customers – we’re mass-producing the highest-power satellite platforms ever built for missions from LEO to deep space.

The rise of heavy-lift launch vehicles is shifting the industry from an era of mass constraint to one of mass abundance, and we believe this new era demands a fundamentally different class of spacecraft. Engineered to survive the harshest radiation environments and to fully capitalize on today’s and tomorrow’s massive rockets, K2 satellites deliver unmatched capability at constellation scale and across multiple orbits.

With multiple launches planned through 2026 and 2027, we’re Building Bigger to develop the solar system and become a Kardashev Type II (K2) civilization.

If you are a motivated individual who thrives in a fast-paced environment and you’re excited about contributing to the success of a groundbreaking Series C space startup, we’d love for you to apply.

You will contribute to the build and development of avionics and software test assets for major satellite subsystems and vehicle simulation. This role will be the owner of avionics hardware installation, wire harnessing, test rack fabrication, and HITL (Hardware-In-The-Loop) test bed build and maintenance. As an essential part of the Research & Development technician team, you will demonstrate diverse proficiencies across avionics products, production and industry build fundamentals, and a high level of attention to detail to ensure quality and reliability of electrical components and systems.

• Support full build and maintenance of HITL (Hardware-In-The-Loop) test assets, including installation of avionics hardware, manufacturing and routing of wire harnesses, and fabrication of load simulators
• Assemble production test racks for HITL, acceptance testing, and qualification of flight hardware
• Follow engineering procedures to perform electrical checkouts such as continuity, discontinuity, and multimeter measurements on components and vehicle systems
• Assist design engineering throughout the hardware development and pre-production stages by supporting specification development, component assembly and process validation testing
• Work autonomously and coordinate cross-functionally with various engineering and technician team to meet high pace schedule and quality requirements
• Successfully use an array of hand, power, and pneumatic mechanical tools to build fixtures, interfacing panels, and tooling assemblies

• 5+ years of experience assembling, integrating, and testing electronic hardware in the aerospace industry
• 1+ years of SMT/through-hole soldering, using electronics equipment, and assembling test racks
• Demonstrated skill and proficiency in soldering and crimping as well as assembling cable harnesses and connectors

• IPC Certified for PCB and cable harness rework (IPC-A-610, IPC-A-620)
• Hand soldering ability that meets IPC J-STD-001
• Experience designing, building, and testing electrical assemblies and test fixtures
• Experience performing crimping, wire stripping, continuity testing, connector pin outs, and routing and tie wrapping
• Ability to drill and tap holes, and use common shop equipment such as drill press, grinders, and band saws
• Ability to create, read, review, and redline electrical and test rack schematics
• Strong communication skills with ability to communicate hardware and systems problems
• Experience developing or writing company specifications and qualifying build methods for production around wire harness, test rack fabrication, and integration

• Must be able to perform repetitive tasks such as bending or twisting, grasping, standing, lifting, pulling, pushing, stooping, stretching, carrying, and use hands to operate tools or machine controls
• Must be able to lift and carry parts…
