We’re looking for an AI Solutions Technical Engineering Manager to lead the delivery of AI- and data-enabled products and platforms from early shaping through to measurable outcomes in production. You’ll operate at the intersection of engineering leadership, AI delivery, and stakeholder alignment, turning ambiguous ideas into structured plans, unblocking teams, and ensuring solutions are operationally viable.

You will work across domain teams in a federated model, bringing clarity around ownership, interfaces, and accountability. This is a senior role for someone who can drive innovation while delivering under tight timelines and high expectations.

The role

You will lead multidisciplinary engineering teams (AI/ML, data, software, platform) to deliver AI capabilities that are trusted, adopted, and production-grade.

Day to day, you’re splitting time between running the team and doing real technical work alongside them — reviewing designs and code, prototyping when it’s faster than explaining, and making the calls on deployment, routing, evaluation, and monitoring for our LLM and ML systems. That includes when to use semantic routing versus static routing, when OpenRouter-style multi-provider setups make sense, and how Claude and other models stay integrated cleanly across different tech stacks rather than bolted on inconsistently.

You’ll own technical direction of our text-to-SQL platform. You’re also the technical backstop for agent and MCP work: tool-use design, orchestration patterns, and knowing when MCP is the right call versus overkill.

On models, you decide whether a problem needs fine-tuning or whether better prompting, retrieval, or routing gets there faster and cheaper; backed by real evaluation data, not intuition.

Beyond that, you keep what we ship production-grade — secure, observable, cost-sensible, reliable. You manage the people side properly too: coaching, growth, honest feedback. And you represent AI delivery to senior stakeholders, staying calm and credible under tight timelines and open questions.

What you’ll be doing

• Someone who has actually built and shipped AI/ML systems themselves, recently enough that they can still read and write code and hold their own in a design review
• Real depth on LLM systems — RAG, agentic architectures, tool use, evaluation, guardrails, model lifecycle — not just familiarity with the terms
• Hands-on experience with multi-model or multi-provider setups — routing (semantic routers, OpenRouter or equivalents), fallback strategies, and cost/latency trade-offs across providers
• You’re also the technical backstop for our KAIT platform - our LibreChat-based internal AI tool, covering MCP gateway architecture, agent orchestration, and integrations across Confluence, Jira, Teams, and ClickHouse.
• Practical experience with MCP-based integrations and agent orchestration, including the judgment to know when an agentic approach is overkill
• A working understanding of fine-tuning versus prompt/retrieval-based approaches, and the evaluation rigor to justify the choice with data
• Experience leading a small senior team where you were still the most technical person in the room, or close to it
• Comfortable making architecture decisions without a clear playbook, and confident enough to defend them on technical merit
• Solid production engineering fundamentals - AWS, Kubernetes, CI/CD, observability - enough to have an opinion, not necessarily to build it yourself day to day
• Genuinely plugged into what’s happeni…
