Space System Research Engineer (R&D)

We are seeking a Space System Research Engineer to join our engineering team to help advance our core analysis platform. This is a full-time, in-office role ideal for a strong technical generalist with applied experience in the field and a research-oriented mindset. In this role, you will develop integral simulation and analysis tooling to enable our integrated environment to effectively model, simulate, and optimize spacecraft designs, subsystem parameters, and mission operations. You will act as a critical technical bridge, applying your broad spacecraft systems knowledge to build high-fidelity simulations that solve complex spacecraft design and modeling challenges. Key Responsibilities Architect and develop advanced systems engineering processes, methodologies, and algorithms to analyze and specify spacecraft systems capabilities and requirements. Act as a technical generalist, analyzing multi-disciplinary interactions (power budgets, thermal constraints, ADCS, RF/Communications) of spacecraft. Apply systems engineering principles pragmatically, balancing the need for structured formal processes with the agility required for rapid, proper implementation in an R&D environment. Conduct open-ended research and feasibility studies to understand novel or unexpected spacecraft behaviors. Ensure compliance with necessary industry standards while maintaining a fast-paced development cycle. Document research findings, design processes, test results, and system performance. Minimum Qualifications Bachelor’s or advanced degree in aerospace engineering, systems engineering, or a related field. 3+ years of hands‑on industry or applied research experience in spacecraft systems engineering, with a broad, generalist understanding of multi-disciplinary interactions across various subsystems. Experience in or strong interest in R&D environments focusing on space domain awareness (SDA). Proficiency in programming (e.g., Python, C++, or MATLAB) for modeling, data analysis, and tool development. Strong ability to collaborate effectively in a dynamic, open‑minded environment while maintaining a positive and professional attitude. Excellent problem‑solving skills, intellectual curiosity, and attention to detail. Must possess or be willing and eligible to obtain a United States Department of Defense Top Secret security clearance. Desired Qualifications Advanced Degree: Master’s degree or Ph.D. in aerospace engineering, astrodynamics, physics, or a closely related discipline. Full Lifecycle Experience: Hands‑on experience with the full spacecraft or payload development lifecycle, from concept generation and preliminary design through integration, testing, and on‑orbit operations. Domain Expertise (SDA): Deep technical knowledge of orbital mechanics, orbit determination, electro‑optical/IR sensors, or RF/radar systems as they apply directly to Space Domain Awareness or Space Situational Awareness (SSA). Specialized Software & Tools: Proficiency with industry‑standard astrodynamics and mission analysis software (e.g., AGI STK, FreeFlyer, or GMAT). Testing & Hardware: Experience with hardware‑in‑the‑loop (HITL) or software‑in‑the‑loop (SITL) simulation and testing.
