About the Company
My client is a UK technology company building an AI operating and orchestration layer that puts intelligent systems to work inside large, complex organisations where accuracy and accountability really matter. Their customers operate in tightly regulated environments and the platform is already live and in daily operational use. The engineering group is small, senior and unusually fast moving, with AI tooling built into how the team genuinely works rather than bolted on afterwards.
The Role
This is the role for an engineer who is genuinely good with people and genuinely good with a keyboard. You will sit between customers and the core platform, running discovery, shaping what good looks like, and then building it rather than handing it over. Expect to be in rooms with senior stakeholders explaining trade-offs honestly, then back at your desk making the thing work. It suits someone who has grown tired of consultancy that stops at the slide deck.
Key Responsibilities
Lead technical discovery sessions with customers to define real, solvable problems
Shape AI solution designs and take ownership of delivering them
Build LLM and agent-based workflows on the core platform
Define success criteria and evaluation approaches with customers up front
Manage expectations and surface issues early rather than late
Identify follow-on opportunities within existing accounts
Codify repeatable delivery patterns for the wider Solutions team
Act as the trusted technical voice for a portfolio of accounts
What You'll Need
Essential:
5+ years in a client-facing technical role, consulting or solutions engineering
Strong Python and production experience with large language models
Track record of shaping and delivering technical solutions for external customers
Confident communicator with senior and non-technical stakeholders
Working fluency with modern AI development tooling
Eligible for UK security clearance
Desirable / Nice to Have:
Experience delivering into a heavily regulated sector
Exposure to retrieval augmented generation and evaluation frameworks
Why Apply?
Consulting work that ends in shipped capability rather than recommendations
Serious problems for serious clients, with real operational consequences
Share options as part of the package
Small team, minimal process, decisions made quickly
Flexible working pattern
Real exposure to founders and commercial leadership
Scope to define how the Solutions function operates as it scales
