E-Space US – Engineering, Manufacturing & Operations /
Full-Time /
On-site
Ready to make connectivity from space universally accessible, secure and actionable? Then you’ve come to the right place!
E-Space is bridging Earth and space to enable hyper-scaled deployments of Internet of Things (IoT) solutions and services. We are building a highly-advanced low Earth orbit (LEO) space system that will fundamentally change the design, economics, manufacturing and service delivery associated with traditional satellite and terrestrial IoT systems.
We’re intentional, we’re unapologetically curious and we’re 100% committed to innovate space-based communications and deliver actionable intelligence that will expand global economies, protect space and our planet and enhance our overall quality of life.
We are looking for a rigorous and versatile Senior Software Engineer to join our Guidance, Navigation, and Control (GNC) team. You will take a central role across the full GNC software stack – from embedded GNC flight software running on orbit, to high-fidelity simulation environments, to the associated test and validation frameworks that ensure mission success. You will collaborate closely with the GNC, flight software, and assembly, integration, and test (AIT) teams. This position is based in our Saratoga, CA office.
What you will do:
- Translate prototypes and software specifications for GNC estimation and control algorithms into production-ready flight software.
- Develop and maintain high-fidelity closed-loop simulation environments (MIL, SIL, HIL), implementing software models for dynamics, perturbations, actuators, and sensors behavior from prototypes.
- Build and maintain robust and scalable test and validation infrastructure for GNC flight software, including automated CI/CD pipelines, regression suites and Monte Carlo simulations.
- Contribute to system-level AIT and support in-orbit operations of mission-critical satellite software.
- Uphold best practices in code quality, documentation, and configuration management within a collaborative, multi-developer environment.
What you bring to this role:
- Bachelor’s or Master’s degree in Computer Science, Software Engineering, or related field.
- 4+ years of professional experience in embedded software development and test automation.
- Proficiency in C/C++, Python, with strong grounding in object-oriented programming.
- Skilled in Git and modern version-control workflows, within collaborative, multi-developer environments.
- Proven track record designing and implementing comprehensive test suites, including unit, integration, regression, and large-scale Monte Carlo tests.
- Solid experience implementing modular and maintainable software architectures.
- Experience with RTOS environments with real-time constraints.
- Familiarity with multithreaded programming and synchronization techniques.
Bonus points:
- Experience with Matlab/Simulink, model-based simulation environments, including MIL, SIL, and/or HIL.
- Background in satellite flight software, GNSS data processing, attitude estimation, control systems.
- Familiarity with modern development and operations tooling, such as Docker, JFrog Artifactory, Grafana dashboards, the Atlassian suite (JIRA, Confluence, BitBucket)or similar platforms.
This is a full time, exempt position, based out of our Saratoga office. The target base pay for this position is $100,000 - $200,000 annually. The total compensation packaged will be determined by various factors such as your relevant job-related knowledge, skills, and experience.
We are redefining how satellites are designed, manufactured and used—so we’re looking for candidates with passion, deep knowledge and direct experience on LEO satellite component development, design and in-orbit activities. If that’s your experience – then we’ll be immediately wow-ed.
E-Space is not currently able to provide employment sponsorship for candidates who do not hold work authorization for the location of this role.
