Senior Dynamics 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 As a member of our growing analysis team you will help own the successful derivation of loads and environments for K2 Space satellites during ground transportation, launch, deployment, and on-orbit operation. You will build software tools and establish simulation workflows to support a variety of analyses in frequency and time domains. Within your first couple of months you will devise development testing to correlate physics models with measured data. You will also own qualification and acceptance testing of satellite hardware at the component and vehicle level. As we continue to refine our designs and scale for the future you will be responsible for delivering well-derived requirements and engineering insights to make reliable and mass-producible spacecraft. Responsibilities Drive vehicle-level dynamic testing from start to finish including test planning and coordination, test analysis, and model correlation Innovate on cross-disciplinary analysis and test methodologies Evolve spacecraft dynamics approaches to optimize for the company’s business Develop physics models using finite element analysis and custom-built software Create software tools to support data processing and simulation frameworks Collaborate with design engineers, analysts, and external customers to develop payload products Apply first principles in developing frameworks for both dynamics and non-dynamics analyses Perform code reviews for simulation and analysis tools Utilize analysis and test to provide data-driven engineering guidance and decisions Write high quality technical documentation of tests and simulations Qualifications Bachelor’s degree in mechanical engineering, aerospace engineering, physics, or mathematics 5+ years of work experience in dynamics from industry or academia Nice to have Master’s degree in mechanical engineering, aerospace engineering, physics, or mathematics Strong understanding of low and high frequency dynamics (vibration, acoustics, shock, modal testing) Deep experience with testing and measurements Deep experience with finite element analysis software (e.g. FEMAP, Nastran) Strong experience in software development in Python Deep knowledge of digital signal processing, statistics, and structural mechanics Capable of identifying and solving complex problems with little to no supervision or direction Excellent communication skills of analysis and test insights. Ability to work in a fast-paced, unstructured start-up environment.
