What you’ll do

Working closely with Pre-Sales Consultants, you’ll lead the technical side of sales engagements, from deep-dive sessions on architecture and data models, through solution design, to handing off to implementation teams at contracting.

- Tenders and proposals: Provide technical input into tender responses and proposals, and deliver compelling technical presentations with product and technology teams
- Proof of concept: Partner with Pre-Sales Engineering to shape and design proof-of-concept exercises
- Product advocacy: Act as the bridge between market demand and our engineering teams, so client needs shape the roadmap and proposed solutions align with core platform capabilities
- Measurable outcomes: Advise clients on achieving measurable business outcomes through a data-driven approach, and help quantify the value of the platform in commercial conversations
