K2 is building the largest and highest-power satellites ever flown, unlocking performance levels previously out of reach across every orbit. Backed by over $1 billion in total funding from leading investors including Altimeter Capital, ICONIQ, Kleiner Perkins, Lightspeed Venture Partners, Redpoint Ventures, and T. Rowe Price — and with over $1 billion 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 in 2027 and plans to scale to 100 satellites a year, we're Building Bigger — helping develop the solar system and build toward 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 high-growth Series D-funded company, we'd love for you to apply.

The Role

You will play a key role in the development and production of the avionics systems for the K2 Mega-class satellite platform. This position requires deep technical expertise in reworking high reliability PCBAs, collaborating closely with Design and Test Engineers, and supporting avionics testing infrastructure and flight builds. You will also support wire harness fabrication as needed to help support the wider team.

Responsibilities

Perform precision hand soldering and rework of printed circuit boards (PCBs), including removal and replacement of 0402 and smaller SMT components using hot air, micro-soldering, and reflow techniques
Hand-solder (population/depopulation) Bottom Termination Components (BTC)
Modify traces or pads and run jumper wire on PCB
Support subassemblies and fabricate test harnesses for avionics testing
Perform component kitting from inventory as needed
Support hardware troubleshooting with Engineering teams to resolve board failures and design updates
Maintain ESD-safe practices at all times when handling electronics
Provide training to other technicians to help scale production across development and flight
Provide consistent process improvement feedback to Engineering and Production Leadership

Qualifications

5+ years of experience soldering electronic components for PCBAs
Proficiency with basic tools: soldering irons, hot air tools, and component handling for 0201, 0402, and BGA/QFN packages
Experience with reballing and reworking fine-pitch BGAs
Demonstrated ability to rework and repair complex assemblies to IPC-7711/7721 standards
Experience building and inspecting flight-quality cable and harness assemblies
Ability to follow schematics, work instructions, and drawings with minimal supervision
Familiarity with ESD requirements for components and PCB/PCBAs
Demonstrated high level of ownership and problem-solving skills

Nice to Have

IPC-A-610, IPC-A-620, IPC-7711/7721, J-STD-001, NASA-STD-8739.3
Experience fabricating harnesses from assembly drawings and schematics
Ability to read, review, and redline electrical schematics and mechanical drawings
Experience with various potting and encapsulation techniques
Previous experience supporting environmental or functional testing of avionics assemblies
Strong communication skills with ability to communicate hardware and systems problems

Additional Requirements

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 or equipment up to 50 lbs. unassisted
Must be able to stand for extended periods of time
