Avionics Software Engineer

<h3><strong>About Lodestar</strong></h3> <p>Lodestar's mission is to develop the first "Protect and Defend" capability for high-value space assets in orbit. Our flagship product, MITHRIL, is our hardware-agnostic, AI-enabled autonomy software suite that enables us to augment any off-the-shelf spacecraft with the ability to autonomously detect, characterise, and reversibly neutralise orbital threats. By building on the proven space heritage of our best-in-class satellite-bus partners and fully integrating MITHRIL into a single unified platform, we deliver an end-to-end, autonomous in-space bodyguarding service.</p> <hr> <h3><strong>About the Job</strong></h3> <p>We’re hiring <strong>Avionics Software Engineers</strong> across three technical focus areas: <strong>Flight Software, Distributed Middleware &amp; Embedded Linux</strong> Depending on your experience, you’ll take ownership of one of these areas while working closely across avionics, autonomy, AI/ML, and hardware.&nbsp;</p> <hr> <h3><strong>What You'll Do</strong></h3> <p>Within our Avionics Software team, we're hiring multiple engineers across three core technical specialisms. Please identify which role best matches your skills and experience:&nbsp;</p> <h3><strong>1. Flight Software Engineering</strong></h3> <ul> <li>Design and develop deterministic, safety-critical, fault tolerant flight software for autonomous spacecraft.</li> <li>Build robust software for RTOS-based flight computers, implementing FDIR and defensive programming techniques.</li> <li>Collaborate with autonomy, AI, and hardware engineers to integrate, test, and validate mission-critical software on representative spacecraft platforms.</li> </ul> <h3><strong>2. Distributed Middleware Engineering</strong></h3> <ul> <li>Develop the distributed middleware enabling communication, workload orchestration, and telemetry across heterogeneous onboard compute systems.</li> <li>Build resilient software infrastructure including high-performance IPC, networking, process supervision, and fail-safe Over-The-Air (OTA) update mechanisms.</li> <li>Deliver scalable software platforms that support fault-tolerant autonomous operations.</li> </ul> <h3><strong>3. Embedded Linux Engineering</strong></h3> <ul> <li>Develop and maintain custom embedded Linux platforms for NVIDIA Jetson-based flight computers, from board bring-up through to deployment.</li> <li>Optimise kernel performance through real-time tuning, low-level driver development, system profiling and selective kernel slimming.</li> <li>Architect a hardened, minimal-footprint Linux-based operating system.</li&
