Mechanical Hardware Engineer
About the role
Hands-on mechanical engineer responsible for designing, building, and testing the physical systems around the company's electronics, including airframes, enclosures, mounts, thermal solutions, payload integration, and packaging for autonomous drones.
Responsibilities
- Design mechanical parts and assemblies for defined subsystems under the direction of the Founding Hardware Engineer: airframe components, enclosures, mounts, payload interfaces, and ground station hardware.
- Own prototyping and iteration for your subsystems: 3D printing, CNC and sheet-metal parts, fit checks, and rework through fast design cycles.
- Design for the environment: vibration, shock, thermal management, ingress protection, and weight targets on flying platforms.
- Integrate electronics into airframes: packaging, cable routing, connector placement, and serviceability, working closely with the electrical team.
- Build and maintain aircraft: assembly, repairs, and configuration control across our test fleet.
- Run test campaigns with our testing lead: prepare aircraft, capture data, log failures, and feed findings back into the next revision.
- Work with manufacturers on quotes, DFM feedback, tolerances, and incoming inspection as we scale production.
- Use AI tools to accelerate design, analysis, and documentation.
Qualifications
- Minimum 2 years of hands-on mechanical engineering experience (professional, or an equivalent portfolio of shipped personal projects).
- Strong CAD skills in SolidWorks, Fusion 360, or similar.
- Solid grounding in materials, fastening, tolerancing, and design for manufacture.
- Confident in the workshop: 3D printers, hand tools, and methodical fault-finding on physical assemblies.
- Comfortable with the gap between bench work and field operation.
- Bias toward shipping.
- Comfortable testing in real-world conditions.

About Seeing Systems
Modular AI-Commanded Drones for Defence
We're building inexpensive, autonomous strike drones designed to stay operationally relevant as warfare evolves. By combining true hardware modularity with an agentic control system that lowers cognitive load on operators, we enable faster upgrades, broader adoption, and more than 2x reduction in lifecycle cost. Our customers and partners include the UK Royal Marine Commandos, several other units in the UK, and 4 other NATO forces, and we are currently shipping prototypes for iterative feedback. Think of us as Anduril, but with worse weather, and better banter.
