Role
Who you are
- 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
What the job involves
- Engineering - reporting to the CPTO
- 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
- 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
- Building Eliza taught us that great AI agents in sensitive, human contexts are harder than they look. Here's what you'll be working on:
- 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
Application process
- Screening interview led by Lottie’s Talent Acquisition Lead
- First round interview led by Hiring Manager
- Technical assessment comprising two parts: a) AI-enabled coding pairing session with two Lottie engineering team members, b) System design interview with two engineering team members
- Behavioural interview with Hiring Manager
- Final interview with Will Donnelly (Lottie’s Co-Founder & CEO)
- The majority of feedback will be given via email and we try our very best to give specific and constructive feedback where possible
- Pre-Screen & First Interview: You'll receive an email notification, but no specific feedback will be provided at this stage
- Engineering Manager Interview: If you are unsuccessful after this interview, you will receive constructive feedback via email
- Technical Rounds: If you are not successful after these, you'll receive constructive feedback via email and be offered a debrief call with our Talent Lead
- Final Interview: For final-stage candidates who are not offered the role, we will provide your feedback live via a phone call
Salary benchmarks
Our take
Choosing a care home is often a hugely daunting, complex, and expensive process, coming at a time that's already stressful enough. What's more, the UK's ageing population is growing at an increasing rate, putting more strain on social care than ever before. The result is that 44% of care seekers often ultimately regret their choice of care home, something that has had increasing attention since the start of the COVID-19 pandemic.
Lottie aims to address this in part by simplifying the process of finding the perfect care home for every individual's specific needs. Its online marketplace gives users all the tools to select and compare the UK's best-performing care homes, taking into account CQC reports, facilities, treatment methods, and location.
Having received investment, Lottie aims to continue its growth to reshape the future of the care industry. It is doing so with a strong emphasis on data and real-time information, collecting datasets that will be vital not just to its business operations, but potentially to the UK government and healthcare policy too.
