We're looking for a Pre-Sales Technical BDE to lead managed services pursuits. This role owns the technical dimension of winning work: discovery, solution shaping, proposal development, and presentation, across both current-logo opportunities and expansion opportunities originated by the Customer Success (CSM) team and Sales.

It's a customer-facing role for a senior architect who can sell. Someone with broad infrastructure architecture depth across hybrid platforms and cloud, with particular strength in security, resilience, backup and disaster recovery, who can translate technical possibility into commercially sound, deliverable managed service solutions.

What you’d do: Lead technical discovery with prospective clients, design practical and commercially viable managed service solutions, and own the technical side of proposals and RFx responses. You’d present to audiences from engineers to executives, with a particular focus on security, resilience, backup, and disaster recovery. You’d also work with CSMs and Sales to turn expansion opportunities into closed deals, help originate and qualify cloud and cyber opportunities, contribute reusable patterns and collateral to Tech Council, and feed field insights back to service owners.

How success will be measured: Qualified pipeline sourced and supported (new and expansion), technical win rate on pursuits you support, and the quality and reuse of collateral you contribute.

Who we want:



Someone with strong architectural judgement who knows when to go deep and when to bring in specialists, communicates complexity simply, influences through expertise rather than authority, is self-driven and comfortable working on-site with clients.

Requirements: Significant solution architecture or pre-sales experience in managed services, broad infrastructure knowledge (hybrid, cloud, networking, security, modern ops), proven depth in security and resilience design, cost-to-serve awareness and a track record in the full pre-sales cycle. Awareness of automation and AI in managed services is a plus, as are certifications such as cloud provider, security, TOGAF, or SABSA.
