Make a phone conversation feel natural, even when the network is not. Own the real-time voice systems at the heart of Jodie, where latency, interruptions and reliability all shape the customer experience.
The work matters.
Jodie AI is a UK company building an AI receptionist for busy businesses. Jodie answers calls, captures the important details and helps owners get back to customers, even when they can't pick up themselves. Work remotely with our London engineering team. This specialist role is open in the UK and Ireland; it is not a work-from-anywhere arrangement.
What you'll own
- Build production voice agents with LiveKit Agents and Python or Node.js.
- Improve turn detection, interruptions, speech recognition and synthesis across real customer conversations.
- Own SIP and telephony integrations, call transfers and graceful recovery when a provider fails.
- Measure end-to-end latency, completion rates and conversation quality with traces and repeatable evaluations.
What you'll bring
- Hands-on production experience with LiveKit and real-time voice applications.
- Strong Python or TypeScript/Node.js skills and an understanding of asynchronous systems.
- Practical knowledge of WebRTC, SIP, audio pipelines and network failure modes.
- Experience evaluating voice quality and safely shipping changes to a live service.
Useful, but not essential
STT/TTS provider evaluation, VAD, multilingual audio, load testing and privacy-conscious call observability. You don't need a particular degree or every nice-to-have. Show us the relevant work you've done and how you think.
Your first 90 days
- By day 30: Map the call path, reproduce common failure modes and establish useful measurements.
- By day 60: Ship a tested improvement to latency, interruption handling or call reliability.
- By day 90: Own a repeatable evaluation and release process for a meaningful part of the voice stack.
Where and when you'll work
Full-time, 37.5 hours a week. Based in the UK or Ireland, with at least four working hours overlapping 09:00-17:00 London time. London HQ is also an option. You'll need to be based in one of the listed countries. We'll confirm the employing arrangement, local benefits and any location restrictions with you before moving to an offer. Tell us your location and whether you need visa sponsorship when you apply; sponsorship and relocation support are not guaranteed.
What you'll earn
Annual base salary, before tax: GBP 140k - 180k (or EUR 165k - 210k).
The benefits
- 30 days of paid annual leave, plus the public holidays where you work.
- A GBP 2,000 annual learning budget, or local-currency equivalent, for courses, books and conferences.
- A company laptop, the software you need and a suitable workspace setup, with support getting your home workspace ready for remote roles.
- A 5% employer pension contribution for UK employees.
- A published salary range, real ownership and direct access to decision-makers.
Hiring process
A first conversation about your experience, the work, location and compensation; a look at how you work (discuss a voice pipeline and diagnose a sample trace with latency and interruption issues); then meet the team.
