Sales Engineer
We’re supporting a clean-energy startup company in London with a requirement for a Sales Engineer. This position sits within the commercial function and reports into the CPO.
The business is moving from proof-of-concept to pilot-scale electrolyser deployment and needs someone who can sit between technical development and commercial teams — explaining complex technical challenges clearly, handling customer questions, and helping shape customer proposals.
This is an excellent opportunity for someone technical who naturally communicates well, enjoys simplifying complexity, and wants exposure across customer, product and market-facing work.
Key Responsibilities
Act as the technical link between R&D/engineering teams and commercial teams.
Support customer meetings, calls and demos, explaining how the technology works.
Translate customer requirements into clear technical inputs for internal teams.
Prepare concise technical presentations, proposals and written responses.
Simplify complex engineering and electrochemical concepts into customer value.
Support the creation of marketing materials, grant applications and investor content.
Respond to customer and partner technical queries.
Maintain an up-to-date view of hydrogen, electrolyser and competitor technologies.
Work closely with product, engineering and commercial leadership.
Develop toward a full commercial role over time (clear progression pathway).
Candidate Profile
2–4 years’ experience in an engineering or scientific role.
Degree in Chemical, Mechanical, Electrical, Process Engineering or related scientific field.
Strong interest in commercial work; ideally some customer exposure.
Excellent written and verbal communication skills.
Comfortable simplifying complex technical problems for mixed audiences.
Curious, proactive, and able to operate in a fast-moving scale-up environment.
Able to build strong relationships internally and externally.
Right to work in the UK.
Desirable
Experience with hydrogen, fuel cells, electrolysis, industrial gases or clean-tech systems.
Exposure to commercial proposals, techno-commercial assessments or grant funding.
What’s in it for you?

You’ll receive hands-on coaching from the commercial and product leadership teams, plus structured development to help you grow from a technically minded engineer into a customer-facing commercial specialist.
