Solve real climate problems with elegant hardware that ships. London-based, salary £60,000–£65,000 plus strong lab access and impact. As a Senior Mechanical Design Engineer, you’ll take ideas from sketch to validated prototypes for sensing-led products tackling emissions in tough, real-world environments. Hybrid working with hands-on prototyping every week.
Scope of the Role
Working closely with electronics, software, and science teams, you will own concept-to-prototype development, de-risking mechanisms, and housings through fast iteration. Your role as Senior Mechanical Design Engineer will be varied, and the scope includes the following:
* Generate early concepts and lead practical ideation for mechanical solutions.
* Build prototypes, run tests, document outcomes, and iterate quickly.
* Create accurate 3D CAD and concise 2D drawings for fabrication.
* Plan and execute trials, reporting issues, and implementing changes.
* Collaborate across hardware, software, and science to resolve system problems.
Key Skills and Experience Required
To be successful in this Senior Mechanical Design Engineer role, you'll need:
* Proven experience in new product development as a Mechanical Design Engineer, Mechanical Engineer, or Product Design Engineer.
* SolidWorks or Onshape fluency, plus precise 2D drawings and tolerance stacks.
* DFM knowledge: 3D printing, CNC machining, vacuum casting, and supplier engagement.
* Hands-on prototyping with Arduino-based rigs, sensor selection, and iterative testing.
* Communicates complex engineering ideas clearly in ambiguous, startup settings.
What you'll get
* £60,000–£65,000 basic, depending on experience.
* Hybrid: four days on site in London.
* Access to on-site prototyping and testing resources.
* Opportunity to shape next-generation sensing hardware from early development onward.
You’ll join a mission-centred, warm, and candid team that values clear thinking, strong communication, and practical decision-making. Expect fast feedback, respectful challenge, and a shared focus on measurable climate impact. It suits a Senior Mechanical Design Engineer who enjoys ambiguity, moves quickly, and cares about real-world performance.
