Senior Test Bed Engineer

Join to apply for the Senior Test Bed Engineer role at Logos Space
.

Logos Space is a Low Earth Orbit (LEO) satellite system purpose-built to serve the connectivity needs of commercial enterprise users and government users. We provide resilient, high‑performance satellite‑based connectivity services worldwide, extending cloud and data center network connectivity to fixed, seaborne, and airborne terminals.

The Sr. Real‑Time Emulation System Engineer will lead the design, development, integration, and deployment of complex Hardware‑in‑the‑Loop (HIL) and Software‑in‑the‑Loop (SIL) simulation systems. This role is critical for rigorously testing, validating, and optimizing satellite flight software, onboard subsystems, and mission control systems before launch and during on‑orbit operations. The ideal candidate is a subject‑matter expert in satellite GN&C subsystem architecture, flat‑sats, and advanced simulation/emulation technologies.

• Emulation System Architecture:
  Architect, design, and lead the implementation of a high‑fidelity space‑vehicle emulation system, or "flat‑sat", including attitude determination and control, payloads, command & data handling (C&DH), power subsystems, etc.
• Real‑Time Software Development:
  Develop and optimize real‑time software and hardware that accurately and deterministically reflects the physical properties, responses, and timing of the satellite.

• Education:
  
  Bachelor’s or Master’s degree in Mechanical Engineering, Electrical Engineering, Aerospace Engineering, or a STEM field.
• Experience:
  
  5+ years of progressive experience in real‑time embedded systems engineering.
• Technical Proficiency:
• Proficiency in real‑time programming and scripting languages such as Python for modeling and test automation.
• Background in embedded systems and real‑time operating systems (RTOS).
• Proficiency with simulation tools such as MATLAB/Simulink and Ansys Systems Tool Kit (STK) for system modeling.
• Experience with data acquisition systems and spacecraft communication protocols (RS422, UART, CAN, etc.).

• Master's degree in Mechanical Engineering, Electrical Engineering, Aerospace Engineering, or a STEM field with relevant design and analysis work experience.
• Experience with Digital Twin technology application in aerospace.
• Experience with FPGA or VHDL for hardware‑level modeling.
• Familiarity with Agile development practices, including Dev Ops and workflow management tools (e.g., Git, Jira).
• Experience with a full product lifecycle (concept, design, integration & test, operations).
• Experience developing and validating operational flight dynamics systems, leveraging knowledge of orbital mechanics and spacecraft attitude determination and control systems (ADCS/GNC).
• Ability to obtain and maintain a U.S. Government Security Clearance.
