The posting

We are looking for a talented and enthusiastic Software Engineer to join the Simulation, Integration and Test Department with a passion for launching hardware into space and a desire to revolutionize the space industry. Our ideal candidate thrives in a highly collaborative environment and enjoys finding ways to innovate and make processes more efficient.    This team builds new simulation capabilities, proves they are correct, and authors the mission scenarios that exercise them. In this role you will write the models that stand in for a real spacecraft, including the dynamics, the avionics interfaces, and the telemetry, and you will be responsible for their accuracy. When a regression test passes against your simulator, the flight software team needs to be able to trust that result. You will work closely with the Systems Architecture and FSW teams as new vehicle components come online, building the simulation capability to match and validating that it behaves the way the real hardware does.    Responsibilities 

Develop and maintain the physics simulator, improving both model fidelity and runtime performance  Develop new simulation capabilities in step with new vehicle components, and validate that they model real behavior correctly  Author, develop, and integrate mission test scenarios, including fault and off-nominal cases  Build and maintain interface emulator logic  Model telemetry accurately enough to support meaningful regression testing  Support and extend development targeting the hardware interface with the simulation environment  Collaborate with the Systems Architecture and FSW teams on new component development  Collaborate with other teams on simulation health  Support internal users directly and incorporate their feedback into the simulation models  Follow SIT software development processes to ensure fast and quality releases  Implement software development, testing, and CI/CD practices that meet division and department standards for software  Develop and maintain product documentation, user guides, and model validation records 

  Required Qualifications 

Bachelor's degree or greater in Aerospace Engineering, Mechanical Engineering, Physics, Computer Science, or related field  2+ years of experience in software engineering or a related field  Demonstrated development experience in Python and C++  Working knowledge of physics-based modeling, numerical methods, or control systems  Demonstrated proficiency in a Linux environment and with bash scripting  Demonstrated proficiency with Git and modern Agile software development practices and tools 

  Desired Qualifications 

Coursework or experience in orbital mechanics, attitude dynamics, or GN&C  Experience emulating hardware interfaces or spacecraft bus protocols such as CAN, SpaceWire, or RS-422  Experience writing performance-sensitive simulation or real-time software  Experience validating models against test or flight data  Experience designing and working with APIs  Familiarity with spacecraft flight software and avionics architectures  Experience with Docker and containerization  Experience with CI/CD pipelines, especially GitLab CI/CD  Experience with Software-in-the-Loop (SITL) and/or Hardware-in-the-Loop (HITL) test systems  Experience in end-to-end, system-level automated testing  Experience with agentic or AI-assisted software development workflows  Ability to interface with and handle flight hardware  Familiarity with the space domain and satellite operations  Networking concepts like UDP/TCP  Active Top Secret security clearance or ability to obtain

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
