Senior Integration & Test Engineer

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. The Role You’ll sit at the heart of bringing our satellites to life. You’ll lead critical ground-side test campaigns, guide cross-functional teams, and shape the systems and processes that ensure every vehicle performs flawlessly from first power-on through on-orbit activities. In this role, you’ll mentor others while staying close to the hardware: commanding powered spacecraft, resolving anomalies in real time, and driving readiness for launch. Your leadership will raise the bar on quality, reliability, and speed, building the foundation for repeatable, high-confidence operations. As we evolve from hands-on procedures to a highly automated production operation, you’ll define the standards, tools, and best practices that make that transformation possible. Your work will directly influence how we scale, how we operate, and how fast we can put new capability on-orbit. If you thrive at the intersection of engineering rigor, system-level thinking, and high-stakes operations, this role puts you in a unique position to shape the future of production test at K2 Space. Responsibilities Operate spacecraft (interpret telemetry, send commands) during system tests at the factory, test facilities, launch sites, and during pre-launch operations Collaborate with design and systems engineers to define test plans with pass/fail criteria for vehicle checkouts Mentor more junior members of the team Interface with customers to scope testing performed on their payloads, based on expected functions and failure modes of interest Manage relationships with launch vehicle providers, including contractual deliverables such as interface control documents and environmental test plan justifications Assess risks associated with different integration and test approaches, justify test reductions and optimize vehicle build/test flows for at-rate production Own and maintain HITL table configuration and build out, including the test racks Influence the design of the vehicle’s flight software and the supporting in-house tools that operators use daily Understand vehicle operations and become an expert for multiple subsystems on the vehicle Support pre-launch activities at the launch provider’s payload processing facility Qualifications Bachelor’s degree in electrical, aerospace, mechanical, computer, or other relevant engineering discipline 5+ years of experience in an integration/test/automation engineering role 3+ years of experience testing and troubleshooting spacecraft and their related components and systems, including subsystem checkouts and system acceptance testing Experience with environmental testing, such as thermal vacuum or random vibration Experience working in a clean room and with ESD-sensitive equipment Hands-on experience using electrical test equipment (PSU, Oscilloscope, DMM, etc.) Hands-on experience with HITL or Flatsat software verification testbeds Excellent conflict resolution and negotiation skills Nice to Have Background in designing test architectures or building automated test frameworks Proficient in Python and/or Rust Experience with Linux systems Experience managing contractual interfaces (e.g. customer, launch vehicle) Compensation and Benefits Base salary range for this role is $140,000 - $175,000 + equity in the company Salary will be based on several factors including, but not limited to: knowledge and skills, education, and experience level Comprehensive benefits package including paid time off, medical/dental/vision coverage, life insurance, paid parental leave, and many other perks If you don’t meet 100% of the preferred skills and experience, we encourage you to still apply! Building a spacecraft unlike any other requires a team unlike any other and non-traditional career twists and turns are encouraged! If you need a reasonable accommodation as part of your application for employment or interviews with us, please let us know. Export Compliance As defined in the ITAR, “U.S. Persons” include U.S. citizens, lawful permanent residents (i.e., Green Card holders), and certain protected individuals (e.g., refugees/asylees, American Samoans). Please consult with a knowledgeable advisor if you are unsure whether you are a “U.S. Person.” The person hired for this role will have access to information and items controlled by U.S. export control regulations, including the export control regulations outlined in the International Traffic in Arms Regulation (ITAR). The person hired for this role must therefore either be a “U.S. person” as defined by 22 C.F.R. § 120.15 or otherwise eligible for a federally issued export control license.
