Catalyx Space is developing next-generation entry systems for space. As a Systems Engineer, you will own the definition, integration, and validation of spacecraft and reentry systems across all engineering domains. You will work hands-on with propulsion, aerodynamics, thermal, mechanisms, structures, and avionics engineers to ensure the vehicle operates as a coherent system. Beyond coordination, you will apply strong engineering problem-solving skills, perform system-level analyses and trade-offs, and establish realistic timelines. You will also be responsible for CONOPS development, requirements management, and operational readiness, ensuring mission success from design through flight. Responsibilities: • Own Requirements definition, flow down, and tracking across all subsystems. • Develop and maintain system budgets (mass, power, ΔV, volume, stiffness, thermal margins). • Define system-level interfaces (mechanical, thermal, electrical, fluid). • Lead integration trades and architecture decisions, ensuring subsystem compatibility. • Perform trade-off analyses to balance competing requirements across subsystems. • Perform system-level analyses to validate architecture choices against mission requirements. • Define and maintain CONOPS (Concept of Operations), aligning system design with mission objectives and operational constraints. • Establish and maintain system-level timelines with awareness of technical risks and bottlenecks. • Participate directly in design reviews (Preliminary, Critical, and Test Readiness). • Define and own the system verification & validation (V&V) plan, ensuring test campaigns close requirements. • Drive configuration management and PLM discipline across teams. • Conduct and document FMECA (Failure Modes, Effects, and Criticality Analysis) for system reliability. • Interface with regulatory partners (DGCA/FAA or equivalent) for system compliance. • Collaborate with operations and GNC/Flight Dynamics teams to ensure vehicle performance meets mission design. • Author and maintain system-level documents, including CONOPS, requirements docs, V&V plans, and system test plans. Qualifications: • Bachelor’s/Master’s in Aerospace, Mechanical, or Systems Engineering, or equivalent field. • 5+ years of experience in spacecraft systems engineering or multi-disciplinary aerospace programs. • Prior experience in managing space missions (concept design, integration, testing, and/or operations). • Strong understanding of propulsion, structures, thermal, aerodynamics, mechanisms, and basic avionics (to manage system interfaces and integration). • Hands-on experience in requirements flow down, interface control, trade studies, and system-level analyses. • Ability to define and track mass, power, and ΔV budgets. • Familiarity with system integration testing (vibration, TVAC, propulsion, aero/thermal). • Proficiency in tools like STK, MATLAB, Python, and system modelling frameworks. • Experience conducting or contributing to FMECA analyses. Preferred Skills: • Prior experience on spacecraft or reentry systems that have flown. • Strong problem-solving skills and ability to step into technical challenges outside your core discipline. • Experience with configuration management tools and PLM systems. • Familiarity with safety and regulatory compliance in aerospace programs. • Excellent communication skills, with ability to align diverse teams under one mission timeline. • Willingness to work extended hours and/or weekends as needed.
