Own the physical integration of our autonomy platform into drones, payloads and ground systems. Your work defines the fieldability, performance and production quality of our core hardware.
SE3 Labs is building Spatial AI by combining 3D computer vision with large language models (LLMs). We believe the ability to reason about and act within physical space is foundational to unlocking the next generation of automation, from construction to smart infrastructure, and with a strong focus on defense.
Now, we’re building the physical platform to bring Spatial AI to life. That means high-performance, real-world robotic systems and we’re looking for a skilled, hands-on engineer who can turn strong concepts into robust products.
As Mechanical Design Engineer, Unmanned Systems, you’ll design the mechanisms, enclosures and physical integration of our on-board systems into various UAV platforms. From concept trade-off to CAD to flight test and on to production introduction, you will bring electronics, airframes, payloads and ground systems together into flying, connected and advanced multi-domain systems.
You’ll report directly to our Hardware Lead and collaborate most closely with electronics developers and prototyping team. SE3 sets no bounds on collaboration so you will engage with our customer-facing colleagues and AI software developers to realize an ambitious vision of whole systems with intelligent drones at the center. Mechanical integration will be your domain, and you’ll be trusted to own it independently.
Requirements & Concepts: Translate mission-needs into hardware requirements and trade-off design concepts to meet them
Design & Engineer: Design and refine sealed avionics enclosures, cooling concepts, interfaces, connection and release mechanisms, packaging and integration into UAVs and ground systems such as charging-, control- and launch platforms
Prototype & Iterate: Build, rework, and test hardware with speed and precision, in simulation, test rigs and in flight
Validate & Field-Test: Analyze and improve designs via simulation and real-world testing up until and including exercises with partners and armed forces
Document and Industrialize: Make your work the lasting foundation of our tech and bring it into thousands of customers’ hands in collaboration with our manufacturing partner network
M.Sc. in Aerospace, Mechanical Engineering or a related field
You bring 2+ years of hands-on experience in hardware design and development, ideally including mechanism design from concept to tested (sub-) system
You’re highly proficient in 3D modelling (CAD, preferably Onshape) and creating production-quality drawings
You’re familiar with selection and sizing of structural elements, fasteners, interfaces and thermal paths
You understand kinematics, packaging and electro-mechanical systems
You know when a simple answer is the right answer, and when a design needs deeper analysis, precision and careful consideration
You speak fluent English; German is a plus
Most importantly, you’re structured, fast-moving, and mission-driven. You don’t wait for perfection. You iterate until it works. You love building things that last.
Experience in designing lightweight electronic enclosures for harsh conditions
You’ve independently prototyped and tested mechanisms and seen them through refinement cycles into production
Experience with ISO GD&T, DFM/DFA, FEA interpretation and material selection
Thermal design and analysis for compact electronics or similar systems
Hardware testing & qualification experience (ideally including MIL-STD thermal, vibration, etc.)
Skilled in designing fixtures and test-rigs
Familiarity with light UAVs or aircraft systems or defense equipment
