Reusable orbital infrastructure for payload hosting
Equity: 0.3% – 1% depending on experience
Pillar Space is building reusable satellites that stay in orbit as persistent infrastructure for in-space manufacturing and high-power AI compute. Today, orbital manufacturing means building a satellite, producing a small batch, and discarding the spacecraft. Flagship, our host satellite, instead rents payload slots for months to years and exchanges payloads through repeatable on-orbit rendezvous and docking.
Our leadership includes the only commercial team to have docked and undocked two spacecraft in orbit.
You will build the flight software that runs our satellites, across the full stack: attitude determination and control, command and data handling, the payload manager, the flight manager, the software that runs our guidance, navigation, and control algorithms, and the onboard AI.
Flight software operates everything on board, including the autonomy behind rendezvous and docking, so its quality decides whether a mission succeeds.
You will drive software engineering end to end, from requirements and architecture through implementation, test, and interface control documents (ICDs). We are looking for an engineer who is comfortable with this approach and who will set the standard for quality software at Pillar Space.
This is a hands-on role for an experienced engineer who is technically excellent and executes fast.
Design, implement, and test the flight software stack.
Integrate hardware components into the flight software using their ICDs and drivers.
Design, analyze and implement fault detection, isolation, and recovery (FDIR) strategies across the entire flight software.
Build the AI features of the flight software: onboard inference, in-flight model updates and rollback, and runtime safety guardrails.
Implement the command and telemetry paths between the spacecraft and the ground segment.
Develop safe procedures for patching and updating software on orbit.
Improve CI/CD, automated testing, and code analysis for flight software.
Bring up SITL, PITL, HITL test setups with the I&T and avionics teams.
Run trade studies for flight computers and FSW frameworks.
Document the software for operators, and train the mission operations team to use it.
Work closely with the avionics, GNC, and AI teams and the mission architect, so the software meets the mission's needs.
7+ years of professional experience, with a focus on flight software.
Flight heritage: software you wrote has flown in space.
Excellent C/C++ and software engineering skills, plus experience with Python.
Working knowledge of FSW architectures and frameworks such as NASA cFS, F Prime, or Rocket Lab MAX.
Strong fundamentals in embedded and real-time software, including embedded Linux and an RTOS.
Hands-on hardware integration: bringing up components and debugging at the hardware-software interface.
A track record of building flight software from requirements and architecture through test and ICDs.
Experience with spacecraft data interfaces, protocols such as CCSDS and CSP, and onboard networks such as Ethernet.
Experience running machine learning inference on embedded or space hardware.
Experience with fault tolerance on radiation-exposed hardware.
Experience with FPGA development.

Build ambitious, world-first space hardware alongside an exceptional technical team.
Own the flight software that runs the entire vehicle.
Build and lead one of the most important technical functions at the company.
Work on systems where software, hardware, autonomy, and operations all have to come together.
Define the product, culture, technical standards, and trajectory of a breakthrough company from the beginning.
Take on significant technical and organizational challenges and create outsized impact.

Reusable orbital infrastructure for payload hosting
Pillar Space builds reusable satellites that stay in orbit and act as rentable infrastructure for other payloads. A customer launches a payload in a standardized adapter, and Pillar Space’s satellite autonomously docks with it in low Earth orbit, then supplies power, data, thermal management, mobility and mission operations for the lease, with an optional capsule re-entry to return finished products to Earth. This on-orbit docking-based service lets customers test and operate in microgravity without owning their own spacecraft. The team includes veterans from Northrop Grumman’s Mission Extension Vehicles and alumni from SpaceX and Impulse Space, backed by South Park Commons, with a first mission window targeted for 2028 to provide persistent orbital infrastructure for biotech, semiconductors, materials, and defense clients.
