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 seeking a GNC Engineer to take a key role in the design, development, modeling, integration, and testing of our attitude determination system. The scope includes mission-critical flight software, onboard sensors, and supporting tools and testbeds. You will collaborate closely with teams across GNC (Guidance, Navigation, and Control), software, avionics, and mechanical engineering to develop and deliver robust algorithms, software, and hardware. This is a hands-on role and requires onsite presence at our Saratoga, CA office.
What you will do:
- Design, implement, and tune attitude sensor processing software, including estimators and fault detection algorithms for real-time execution inflight-critical software.
- Build and utilize software tools to process and analyze telemetry for performance assessment, and ground/in-orbit calibrations and verifications.
- Develop and execute test procedures to verify the functionality and performance of sensing hardware and software.
- Develop and validate sensor models for use in high-fidelity GNC closed-loop simulations.
- Develop and operate hardware test beds to characterize sensor behavior and validate estimation software performance.
- Support sensing system validation during satellite assembly, integration, and testing (AIT) campaigns.
- Collaborate with cross-functional teams to provide domain expertise and support integration efforts.
- Contribute to engineering reviews and generate clear detailed technical documentation and test reports.
What you bring to this role:
- BS +5 years / MS +3 years / PhD +1 year in Aerospace Engineering, Electronics, Robotics, or equivalent, with relevant professional experience.
- Direct experience deriving sensing algorithms from first principles, including estimators (Kalman filters) and other sensing fusion and fault detection algorithms.
- Proven end-to-end ownership of a sensing system – from design and implementation to tuning, testing, delivery for mission-critical applications.
- Hands-on experience with sensor drivers and communication protocols, e.g., UART, SPI, I2C and CAN.
- Experience building hardware testbeds using Raspberry Pi, Arduino, Pixhawk or other micro-controllers.
- Familiarity with multi-sensors systems, including combinations of IMUs, magnetometers, GPS/GNSS, Earth sensors, sun sensors, and star trackers.
- Familiarity with structured verification and validation processes for critical applications.
- Proficient in C/C++, Matlab/Simulink, and Python.
- Strong initiative, with excellent teamwork, communication, and documentation skills; comfortable in a fast-paced startup environment.
Bonus points:
- Experience building space, aerial, or ground robotic vehicles.
- Experience with spacecraft orbital and attitude kinematics and dynamics.
- Experience with closed-loop model-based GNC simulations.
- Experience with space industry practices: design, qualification, acceptance, integration, operations.
- Familiarity with CAD and 3-d printing for rapid prototyping.
- Familiarity with PCB schematics, and experience with basic board bring-up and debugging.
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.
