We are seeking a hands‑on engineering leader to build a new product line from the ground up and lead a small team of product engineers working on AI voice & chat agents. You will work closely with our leadership to get this from 0 to 1 in record time, and integrate seamlessly into Found, our operating system for care.

• Prototype and build the foundation for our product; own the technical roadmap.
• Code alongside the team while also sharing the product hat with our GM, supported by our VP Product and CPTO.
• Build and manage a team of three product engineers; help them grow and deliver more impact.
• Ensure a high bar in terms of speed and quality, oscillating between the two as context demands.
• Help the team operate effectively by breaking problems down into simpler ones for fast delivery and impact.
• Wear other hats necessary to the success of the team.

• Build AI voice and chat agents to help care homes provide 5‑star service to people seeking care.
• Ensure our agents provide high‑quality responses and accurate information, with robust evaluation frameworks to measure and improve performance.
• Integrate deeply into Found, our SaaS operating system, leveraging our CRM to enable care seekers to book viewings and get information seamlessly.
• Fine‑tune voice quality, tone, and emotional intelligence to create warm, empathetic interactions that reflect our care values.
• Build systems that balance LLM economics – managing token costs, latency trade‑offs, and knowing when to fine‑tune vs. prompt engineer.

• Self‑starter who thrives in a fast‑paced environment and is comfortable working on challenges with many unknowns.
• 7+ years of hands‑on software engineering experience, including leading technical decisions and mentoring engineers across the stack.
• Hands‑on experience building with LLMs – fine‑tuning models, working with voice APIs, or building eval frameworks.
• Strong opinions on LLM observability, prompt engineering, and building reliable AI systems.
• Extremely product‑mindful and conscious of what great looks like from an engineering standpoint; focus on impact and reducing cost of change.
• Comfortable shipping MVPs that work, then iterating based on real usage.
• Enjoys using AI in workflow – tools like Cursor, Claude, or similar – and understands LLM limitations.
• Has built something 0‑to‑1 and worked in cross‑functional teams.
• Values diversity and inclusion; passionate about creating a space where everyone's voices are heard.
• Brings joy and builds meaningful work relationships.

• The 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; leaders should operate at all levels.
• You don’t know how to be scrappy.

• Screening interview led by Lottie’s Talent Acquisition Lead.
• First‑round interview with the hiring manager.
• Technical assessment: a) AI‑enabled coding pairing session with two engineering teammates, b) system‑design interview with two teammates.
• Behavioural interview with the hiring manager.
• Final interview with Will Donnelly, Lottie’s Co‑Founder & CEO.

• Career‑defining opportunity to lead and shape the future of our flagship marketplace.
• Early hire benefits – fast career progression and generous stock‑options package.
• Mission:
  Tech for good to build the future of the care industry.
• Series A backed; £25m+ VC funding.
• Hybrid office policy and outstanding culture; 5/5 employee review score on Glassdoor.
• Award‑winning company – Linked In 2024 Top Startup, UK’s No. 1 startup 2025 ( 100 Index).
