What you’ll do

As a Pre-Sales Engineer, you are a trusted technical contributor within our team, helping deliver impactful sales engagements through configuration and development in our demo environments. You’ll play a contributor role to larger deals, and often lead pre-sales activities for smaller or less complex opportunities.

This role will report to the Head of Demo Engineering and you’ll be part of a team that works on sales to Kaluza’s largest clients globally.

You will play a crucial role in building product demonstrations and collateral that evangelises the Kaluza platform.

• Own and deliver demo activities for small to mid-size opportunities, especially during high team capacity periods. This includes configuring and delivering tailored product demonstrations and responding to client technical questions with clarity and confidence.
• Support technical delivery on complex deals , working alongside senior team members to prepare solution configurations, contribute to discovery conversations, and ensure client requirements are well captured and translated.
• Collaborate closely with Sales, Product, and Engineering teams to scope solutions, validate feasibility, and communicate trade-offs in a clear and client-friendly manner.
• Lead or contribute to proof-of-concept (PoC) projects , ensuring they reflect client needs and demonstrate our platform’s ability to deliver measurable outcomes. Track PoC success criteria and highlight risks or gaps to the wider team.
• Represent the Pre‑Sales function in internal planning and alignment sessions , helping ensure technical accuracy, smooth handovers, and clear documentation for post‑sale teams.
• Document and share learnings from client engagements , including product feedback, recurring questions, and potential areas for improvement in our pre‑sales approach or demo assets.

What you’ll bring

Ideally, you’ll have:

• Software development experience in a regulated industry using TypeScript, with a track record of designing and building complex solutions to customer problems
• Experience architecting solutions on AWS, knowing which technologies to use when and the trade‑offs involved
• Confidence working with and explaining event‑driven architectures and asynchronous APIs
• Experience in a commercial or client‑facing technical role, ideally selling SaaS in a regulated industry, with examples of adapting a solution to meet a customer’s unique needs
• The ability to distil complex concepts into clear, simple points, and to work through differing opinions with empathy
