Senior Presales System Engineer

I'm hiring for a Lead Pre-Sales Engineer on behalf of our client, a deep-tech company commercialising quantum-enhanced computing. This is a customer-facing technical role, not a back-office solutions job. You'd be the trusted technical adviser to customers buying compute (CPU and GPU), leading the deep technical conversation and moving deals through the funnel without a rep alongside you. What the role involves

• Running technical discovery: working out what the customer really needs, how they make decisions, and what state-of-the-art solution delivers it
• Explaining compute, clusters and performance, and being clear on the trade-offs and why customers choose one architecture or vendor over another
• Positioning the product against commodity CPU and GPU boxes
• Supporting demos and proof-of-concept engagements, and running technical deep dives and presentations
• Travelling to customers and running meetings independently What makes this a great next step
• High autonomy: you shape how technical opportunities get qualified and won
• Direct exposure to Quantum HPC, ML and optimisation, and enterprise customers across chemistry, pharma, energy, finance and defence
• Genuine career runway: as the team scales, there's a real path to owning a region (US/EU/Asia) or moving into a more commercial track
• Small, motivated team with high visibility, and your work directly shapes product roadmap and go-to-market What you need
• A classic technical pre-sales background, with the customer-facing deep dive at the core of your work
• Strong understanding of compute and clusters, able to lead performance conversations with technical buyers
• Experience advising customers on architecture and vendor choices, and explaining the trade-offs
• Strong discovery skills: asking the right questions, understanding the customer's decision process, and presenting technology accordingly
• Self-sufficiency: comfortable getting on a plane and running a customer meeting alone
• A good enough grasp of the product to position it credibly Preferred
• Experience selling compute for simulation, or selling to data centres
• Experience selling against commodity CPU and GPU hardware
• Exposure to ML or optimisation (this can be learnt on the job). Writing code is not required. If this sounds like you, apply today.
