Mechanical Hardware Engineer

About Us "Seeing Systems is building autonomous drone systems that can perceive, navigate, and act intelligently in complex real-world environments." We're advancing autonomy through monocular vision, sensor fusion, and robust system design - drones that keep working where traditional systems fail, supported by an agentic stack that reduces operator cognitive load. Our first product is an FPV-class drone built from the ground up with a modular hardware architecture. If we get the first platform right, we can move fast on everything else: larger airframes, longer range, new payloads, and new mission profiles without rebuilding the stack each time. We were founded by brothers Matthew and Alexander Le Maitre. Matthew is a former Jane Street engineer and Cambridge CS graduate with a background in autonomous systems research. Alexander is a self-taught hardware engineer who has been building unmanned systems and military-grade electronics. We're an early-stage, fast-moving team working at the intersection of robotics, perception, and real-world deployment. We iterate weekly. We test in real environments. The Role You will design, build, and test the physical systems around our electronics as a core member of our growing hardware team. That means hands-on mechanical engineering work across our aircraft and ground stations: airframes, enclosures, mounts, thermal solutions, payload integration, and packaging. You'll take ownership of defined subsystems and see them through from CAD model to a validated part on a flying aircraft. You'll report to our Founding Hardware Engineer and work closely with Alex, our co-founder and hardware lead. This is a role for an engineer early in their career who wants to grow fast: you'll be given real responsibility, real deadlines, and real feedback from the field, with senior engineers beside you at the bench. Within 30 days: you've designed, prototyped, and fitted a part flying on one of our platforms and joined a field test. Within 90 days: you've taken a mechanical subsystem from CAD through prototyping to a validated revision flying on one of our drones. What You'll Do

• 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.

What We're Looking For

• Minimum 2 years of hands-on mechanical engineering experience (professional, or a genuinely equivalent portfolio of shipped personal projects).
• Strong CAD skills in SolidWorks, Fusion 360, or similar - you've taken at least one part from model to manufactured, working hardware.
• 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 "works on the bench" and "works at range in the field."
• Bias toward shipping.
• Comfortable getting outside and testing in the real world with us

Nice to Have

• Defence, aerospace, or UAV industry experience.
• Personal experience building and flying drones, robots, or other unmanned systems.
• Composites experience (carbon fibre layup, moulding, or repair).
• FEA or thermal simulation experience.
• Experience with injection moulding or other volume manufacturing processes.
• Basic electronics literacy (soldering, harnessing, reading schematics).
• Early-stage startup experience.

Why Join

• Real ownership of subsystems from day one, with senior engineers invested in your growth.
• Fast iteration: hardware in operators' hands in months, not years.
• Small, high-agency team with a direct line from idea to field test.
• Real deployment pressure, real feedback, real learning.
• A clear path to grow into broader hardware ownership as the team scales.
• Snack of choice stocked in the workshop.
