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. 1. 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 employee option pool - 28 Days Annual Leave - Comprehensive medical, dental & vision coverage - Contributory pension - Be part of a scrappy, dynamic, multidisciplinary, collaborative crew 🏴‍☠️ Important Information: For security reasons background checks will be undertaken prior to any employment offers being made to an applicant.

Designed for on-orbit SDA, inspection, and effect delivery. - **Orbital Defence as a Service**: End-to-end protection stack for high-value satellites, from detection and intelligence to active response, delivered via a fleet of bodyguard satellites. ## Market Standing - **Valuation/Market Cap**: Not publicly available (private company) - **Key Metric**: Total funding of approximately $3.55M (as of early 2026), comprising a $2.5M Pre-Seed round led by Lunar Ventures and Inflection, plus grants from the UK Space Agency ($1M) and European Space Agency. - **Notable Investors/Partners**: Lunar Ventures, Inflection, UK Space Agency, European Space Agency, Charlie Songhurst, Zehan Wang - **Growth Signals**: - 14 employees with 8 active job postings (indicating rapid scaling) - First satellite payload scheduled for launch in early 2027 - Government contracts and briefings with Pentagon and UK defense stakeholders - Growing European defense budgets (e.g., Germany’s €30-35B by 2030) ## Competitive Advantages - **Purpose-built for defense**: Unlike competitors that repurpose commercial tech, Lodestar designs from the ground up for resilience, responsiveness, and sovereignty in contested orbits. - **End-to-end protection stack**: The only company offering a unified system from detection to autonomous response, rather than point solutions. - **AI-first approach**: The core asset is the AI model, not the satellite hardware, allowing rapid adaptation to evolving threats without long hardware cycles. - **Government trust**: Early backing from UK Space Agency and ESA, plus direct engagement with Pentagon-level customers. ## Strategic Focus - Launch first on-orbit payload to gather proximity data and validate AI models in space - Expand partnerships with allied defense agencies and prime contractors - Scale the team (especially engineering and avionics) to accelerate product development - Win additional government contracts for operational bodyguard satellite systems ## Why Work Here - **Mission-driven culture**: Work on one of the most pressing national security challenges – space defense – with a clear, unapologetic mission to deter conflict. - **Cutting-edge technology**: Tackle hard problems in AI, computer vision, on-board autonomy, and spacecraft systems. - **Small team, big impact**: 14-person team with flat structure; engineers have direct ownership of critical systems. - **Growth opportunity**: Rapidly scaling with 8 open roles; chance to shape the company’s technical direction. - **Locations**: Offices in Los Angeles (HQ) and London, UK; hybrid/remote flexibility likely (based on speculative applications accepted from US and UK). - **Notable perks**: Work with former engineers from MBDA, Orbex, Airbus Defence & Space, and Imperial College London rocketry teams. ## Sources 1.
