## Job description

## 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 are seeking a highly motivated Mid-level Avionics hardware engineer to join our multidisciplinary team developing next-generation space systems. You will be responsible for designing, implementing, and validating advanced avionics architectures for autonomous platforms. This role offers the opportunity to work hands-on across the full lifecycle, from concept and simulation to hardware testing and on-orbit readiness.

## What You’ll Do

- Define and own the avionics subsystem architectures.
- Design, layout, bring-up and validation of PCBs for high-speed digital avionics systems.
- Lead design reviews and drive technical decisions across the hardware lifecycle, working with systems and software teams.
- Conduct hardware debugging and system-level testing using oscilloscopes, logic analysers, and other lab instrumentation.
- Build, test, and maintain electrical harnesses and wiring assemblies for flight and development hardware.
- Collaborate closely with mechanical, systems and software teams to ensure seamless integration of avionics hardware into flight systems.
- Support environmental qualification and verification testing (EMC, vibration, thermal vacuum, etc.)

## Qualifications

- BEng/MEng in Electrical Engineering, related field or equivalent experience.
- 3+ years of professional experience delivering/owning complex electronics hardware projects.
- Proven expertise in complex PCB design, layout, and hardware bring-up/testing.
- Knowledgeable in high-speed interface design and signal integrity analysis.
- Skilled in hardware debugging, fault isolation, and performance characterisation.
- Experienced with lab test equipment including oscilloscopes, DAQs, logic analysers, and power supplies.
- Experience defining board or system-level architecture and leading design reviews.
- Hands-on experience with electrical assembly, including soldering, crimping, and harness fabrication.

## Preferred Skills & Experience

- Experience designing boards for Linux-based SoCs and FPGAs.
- Familiarity with NVIDIA SoMs.
- Hands-on experience with FPGA design and integration.
- Proficient with PCB simulation workflows, including signal integrity, power integrity, and EMC/thermal analysis.
- Background in space-rated electronics and high-reliability design practices, including radiation effects analysis, fault-tolerant architectures, and qualification processes for space systems.

## Compensation & Benefits

- Pay Range:
- (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 🏴‍☠️

## About Lodestar

## Core Business
- **Primary Industry**: Defense and Space Manufacturing
- **Target Customers**: Government and allied defense agencies (B2G); specifically US and allied space asset operators
- **Mission**: To deter conflict in space by providing credible, sovereign orbital defense capabilities through autonomous AI software and satellite platforms.

## Products & Services
- **Mithril AI (Autonomous AI Fighter-Pilot)**: Software that runs on orbital bodyguard satellites, enabling real-time space situational awareness, threat detection, classification, and autonomous response. 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.
