Senior Flight Software Engineer - C/C++ - Up to $250,000

$250k

Attis

Senior Flight Software Engineer

Spatial Intelligence & Space Systems

Venture-Backed Space Logistics Startup

$150,000 - $250,000 Base + Early-Stage Equity

The Company

  • Developing the world's first fully reusable satellite platform designed for controlled atmospheric return and payload recovery.
  • Disrupting disposable satellite paradigms by building reusable orbital infrastructure for commercial, defense, and research sectors.
  • Venture-backed by premier space investors with hardware testing underway for a 2027 demonstration mission.
  • Headquartered in a state-of-the-art engineering facility in Denver, CO.

Why Join?

  • Build flight software from scratch for a vehicle that goes into orbit and comes back to Earth.
  • High-autonomy, tight-knit engineering culture with zero legacy red tape.
  • Direct ownership of autonomous decision-making algorithms and critical vehicle safety logic.
  • Work side-by-side with top-tier aerospace veterans in a rapid hardware prototyping environment.

The Role

A technical, hands-on role where you will:

  • Architect and implement safety-critical C/C++ flight software for spacecraft operations.
  • Develop real-time embedded Linux software for avionics, propulsion, thermal, and payload subsystems.
  • Build autonomous decision-making and Fault Detection, Isolation, and Recovery (FDIR) software.
  • Architect and execute comprehensive SIL (Software-in-the-Loop) and HITL (Hardware-in-the-Loop) test harnesses.
  • Design spacecraft-to-ground communication protocols and telemetry pipelines.
  • Support hardware-software integration, launch preparation, and on-orbit commissioning.

The Essential Requirements

  • U.S. Person status required due to U.S. export control regulations (ITAR/EAR).
  • 7+ years experience developing flight software for spacecraft or safety-critical platforms.
  • Expert proficiency in C/C++ for real-time embedded systems (Linux or RTOS like VxWorks/FreeRTOS).
  • Proven track record building automated SIL and HITL test environments.
  • Willingness to work on-site in Denver, CO, with occasional travel to launch/recovery zones.

What Will Make You Stand Out

  • Experience with atmospheric reentry, heat shields, or hypersonic vehicle controls.
  • Practical knowledge of Rust for embedded platforms.
  • Familiarity with aerospace safety standards (DO-178C, NASA-STD-8739.8) or spacecraft protocols (CAN, RS-422).
