Engineering Manager - AI Agents (Remote) in London

Department: Engineering - reporting to the CPTO

Salary: £95,000 - £125,000 (depending on experience and seniority)

Benefits & Culture: Lottie’s careers page here, Lottie’s tech careers page here.

Equity: A very generous EMI share offering.

Holiday: 26 days + bank holidays.

Mission: Elevate later life for everybody and build the care sector of the future.

Office Policy: Remote (Europe + UK only)

Office Location: London Bridge, London, UK. Quarterly in-person visits expected and financially covered.

The Opportunity:

We built the first version of Eliza — our AI Enquiry Handler for care providers — and she's live. In 50 pilot care homes, she's already reduced missed calls from 53% to 0%. The concept is proven. Now we need someone to really build her.

We're looking for a hands-on engineering leader to own the Eliza product line from here — taking a live prototype and turning it into a category-defining AI product. You'll own the technical roadmap, build and lead a small team of product engineers, and work at the intersection of product and engineering. You'll report to the CPTO with a dotted line to the GM for product direction.

There's a live product and real users, which means real learnings and real pressure to get things right. But this is still very much a founding role — the foundation is there, and almost everything else is still to be built: deeper integrations with Found, live chat, email, observability at scale, and more. You'll be shaping what Eliza becomes.

What does this role involve?

• Owning the technical roadmap for Eliza and our AI agents product line
• Coding alongside the team — this is a hands-on leadership role, not a purely managerial one
• Building and line managing a team of product engineers; helping them grow and deliver more impact
• Sharing the product hat with our GM, supported by our CPTO
• Holding a high bar on both speed and quality — oscillating between the two depending on context
• Deepening Eliza's integration with Found: real-time availability, CRM data, booking flows

What problems will you be solving?

• Scaling a live voice agent that handles real enquiries from families making one of the hardest decisions of their lives — Quality, empathy, and reliability matter enormously
• Deciding what Eliza won't do — scope discipline is as important as capability. Testing is far more complex than it first seems, and scope creep kills quality
• Eval frameworks — measuring and continuously improving response quality, accuracy, and emotional tone at scale
• Managing LLM economics — token costs, latency trade-offs, when to prompt engineer, or model selection.
• Responsible automation — Eliza always tells callers she's AI, escalates when confidence drops, and prioritises trust over completion rate
• Expanding beyond voice into live chat and email enquiry handling

We think you’ll be a great fit if…

• You're a self-starter who thrives with many unknowns — you provide clarity and make things happen
• You have 7+ years of hands-on software engineering experience, including leading technical decisions and mentoring engineers. We work in TypeScript — experience across the stack matters
• You have real experience building with LLMs — prompt engineering, eval frameworks, observability
• You're extremely product-minded — you focus on impact and decreasing the cost of change, not just shipping features
• You know when to use duct tape and when to build for scale — comfortable shipping MVPs, then iterating based on real usage
• Claude Code and AI-assisted workflows are a natural part of how you work — not just something you've heard of
• You've built something from 0 to 1 and worked in cross-functional teams

This role isn’t for you if…

• Our mission to elevate later life care doesn't resonate with you
• You want very clear lanes and don't enjoy working in a fast-paced environment with loosely defined requirements
• You don't enjoy being hands-on anymore. We believe leaders should operate at all levels
• You don't know how to be scrappy
