Presales Engineer

A forward-deployed pre-sales engineer who partners with the strategy and sales teams to design, build, and present AI-powered proof of concepts for clients. You will own the full technical arc of each POC — from brief to build to client demo — and establish a reusable, scalable framework that compounds in value with every engagement.

They are looking for a Pre-Sales Engineer to be their forward-deployed technical force in the sales cycle. This is a hands-on, client-facing role: you will rapidly design and build proof of concepts that demonstrate what is possible with AI, and you will be the technical voice in the room when clients need to see it to believe it. You will report directly to the CTO and work closely with strategy and sales teams across every stage of the pre-sales journey.

What you’ll deliver

• Build proof of concepts that win clients: Take a brief from the strategy team and independently design, architect, and build a working POC within a 3–4 week sprint. Translate real client problems into credible, demonstrable AI-powered solutions. Ensure every POC communicates the key points: what we believe, what we can do, and what the solution could become. Maintain a high output velocity using AI-assisted development tooling.
• Own the client-facing technical narrative: Prepare and support all technical resources for sales calls: demos, slide narratives, technical Q&A docs, and deep-dive presentations. Join first calls, technical discovery sessions, and demo calls to provide credible technical support to the salesperson. Translate complex AI and engineering concepts into clear commercial language for stakeholders.
• Create a scalable, reusable POC framework: After each engagement, produce a clean handover: a client-facing presentation of what was built, what shortcuts were taken, and what hardening would be required for production. Maintain and evolve a library of reusable repo templates, demo environments, and slide narratives.
• Stay at the frontier of AI and shape our offering: Maintain a close watch on the AI landscape: new models, tools, frameworks, and use cases. Proactively suggest new POC formats, tooling improvements, and solution patterns.
• Be a reliable, autonomous operator: Manage your own time and priorities across concurrent POC sprints with minimal overhead. Report clearly and consistently to the CTO on progress, blockers, and decisions throughout the week.

What we’re looking for

• Must have:

• Senior or lead-level engineering experience, with a proven track record of shipping production-quality work independently.
• Full-stack capability: strong React / TypeScript frontend fundamentals with solid backend experience.
• Practical, hands-on knowledge of AI application development.
• Excellent client-facing communication skills.
• A 50/50 builder-communicator profile.
• Demonstrable ability to ship fast and make pragmatic architectural decisions under time pressure.
• Comfortable working solo, managing time independently, and operating with minimal direction.

• Previous founder experience, or a background operating as a one-person engineering function.
• Experience in a product studio, agency, or consultancy.
• Familiarity with a broad range of AI tooling, model providers, and deployment approaches.
• Experience building and presenting technical demos to non-technical enterprise audiences.
• Contribution to sales processes, technical proposals, or RFP responses.
