Job Description
Founding Software Engineer | AI Voice Agents for Skilled Trades
£150k to £300k base + meaningful equity + benefits
London (on-site, 5 days per week)
Founding-level role, high ownership from day one
Sponsorship + relocation bonus from anywhere in the world offered.
The mission
Build AI voice agents that help trades and field services businesses run smoother, scale faster, and deliver a genuinely better customer experience. This is not “AI for vibes.” It’s production automation that answers calls, handles messages, books jobs, and takes actions inside the tools these businesses already use.
The story so far (the bit candidates actually care about)
- Backed by Y Combinator (S23), founded in 2023
- A ~10 person team building fast and in-person
- Recently raised a Series A
- ~$1.5m ARR
If you want a founding role where the product already works, the market is huge, and the backing is real, this is that.
What you will do
- Build and ship core product features across the stack (Python, TypeScript, cloud infra, event-driven systems, third-party integrations)
- Own the lifecycle end-to-end: work directly with customers, scope solutions, ship outcomes, iterate quickly
- Make smart speed decisions: hack an MVP when it unlocks value, then harden it into scalable foundations
- Raise the bar across testing, documentation, reliability, and security as the platform scales
- Build the “hard stuff”: LLM workflows, speech-to-text, text-to-speech, real-time automation, and the glue that makes it reliable in production
What you will bring
- Strong engineering fundamentals: you can design, debug, and ship reliable systems
- Proficiency in Python or TypeScript, or clear proof you ramp fast
- Experience shipping AI products end-to-end (startup, side project, open source, or at scale)
- Comfort working across frontend, backend, and infrastructure (you go where the problem is)
- Confidence working with customers or non-technical stakeholders to scope, negotiate, and deliver
- A track record of ownership (shipping gnarly projects, building things people actually use)
Bonus points for: early-stage startup experience, voice platforms, event-driven systems
The process
Screening chat → hands-on technical → architecture deep dive → references → offer. Adjustments available.
