What you’ll do

As a Pre-Sales Solutions Architect, you’ll sit at the intersection of technology and commercial strategy, shaping how prospective clients understand, adopt and succeed with the Kaluza platform.

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. No two engagements are the same: you might support early-stage prototypes, present at client sites, or advise our Product Architecture team on emerging market needs and common integration patterns.

• Discovery and solution design: Lead discovery workshops to understand current and target architectures, translate complex requirements into solution designs, and define each client’s “to-be” architecture and integration patterns
• Estimate and hand off: Estimate work packages so implementation programmes are set up for success
• 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
