About Lodestar 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. About the Job We’re hiring Avionics Software Engineers across three technical focus areas: Flight Software, Distributed Middleware & Embedded Linux Depending on your experience, you’ll take ownership of one of these areas while working closely across avionics, autonomy, AI/ML, and hardware. What You'll Do Within our Avionics Software team, we're hiring multiple engineers across two core technical specialisms. Please identify which role best matches your skills and experience: 1. Distributed Middleware Engineering • Develop the distributed middleware enabling communication, workload orchestration, and telemetry across heterogeneous onboard compute systems. • Build resilient software infrastructure including high-performance IPC, networking, process supervision, and fail-safe Over-The-Air (OTA) update mechanisms. • Deliver scalable software platforms that support fault-tolerant autonomous operations. 2. Embedded Linux Engineering • Develop and maintain custom embedded Linux platforms for NVIDIA Jetson-based flight computers, from board bring-up through to deployment. • Optimise kernel performance through real-time tuning, low-level driver development, system profiling and selective kernel slimming. • Architect a hardened, minimal-footprint Linux-based operating system. Qualifications The following qualifications are desired across all of these roles: • BEng/MEng in Engineering, Computer Science, or equivalent experience. • Strong foundation in C++. • Experience developing software for embedded systems using Linux or RTOS (e.g., RTEMS, FreeRTOS). • Solid understanding of multi-process architectures and inter-process communication. • Strong communicator and self-starter; able to work independently and in a collaborative team. • Demonstrated skills in debugging and performance characterisation. Preferred Skills & Experience Desired skills and experience relevant to all of these roles: • Good understanding of communication protocols. • Familiarity with containerisation and deployment tools (e.g. Docker, Kubernetes). • Deep understanding of Linux kernel architecture, bootloaders (e.g., U-Boot), and low-level system bring-up. • Understanding of fault-tolerant design principles, error handling, or defensive programming in resource-constrained systems. • Experience with real-time Linux kernel tuning. • Background with the space industry. • Experience with publish-subscribe middlewares. • Exposure to fail-safe Over-The-Air (OTA) update frameworks. • Demonstrated strong problem-solving skills and ability to work in a fast-paced environment. • Proven experience in system integration and working with multidisciplinary teams. Compensation & Benefits • Pay Range: • (E1) Junior Engineer: £30,000 - £55,000 / year • (E2) Mid-level Engineer: £55,000 - £75,000 / year • Meaningful equity incentives as part of our empl
