ROLE OVERVIEW

Our client is hiring a commercially minded Customer Solutions Architect to support complex enterprise energy sales. The role is primarily pre‑sales: technical discovery, RFPs, tenders, proposals and value engineering. Help Account Executives turn customer problems into credible solutions and business cases, working with engineering to validate what can be delivered.

Work with large utilities and other energy businesses across Europe. Sales involve multiple stakeholders, long decision cycles and enterprise software, implementation and professional services. Bring the technical and analytical depth to win those deals.

RESPONSIBILITIES

• Lead RFP responses and proposal development, checking feasibility and requirements with engineering.

• Explain architecture and integration approaches while maintaining focus on commercial outcomes.
• Translate customer feedback into clear requirements for product and engineering.

PROFILE

• At least five years in enterprise pre‑sales, solution architecture or technical consulting, with energy or relevant energy‑adjacent experience.
• Combine customer‑facing commercial work and technical problem‑solving.
• Learn a complex, engineering‑led domain and explain it to executive and technical stakeholders.
• Practical analytical ability: use data, spreadsheets and coding or AI‑assisted tools to model scenarios, test assumptions and build business cases. No specific programming language, protocol or utility platform is a hard prerequisite.
• Experience with complex proposals, RFPs and enterprise buying processes.
• Strong interest in energy and its transition. Relevant European languages are valuable; no specific additional language requirement was confirmed.
