Founding Engineer at well-funded Voice AI startup
- Location
- London, United Kingdom
- Compensation
- £180k + Equity
We are looking for a Founding Engineer to join a well-funded AI startup in London. This isn't just another wrapper; you'll be building a production-grade voice intelligence platform from the ground up.
If you're a specialist in ASR or speech AI with a generalist's ability to ship across the full stack, this is your chance to own the core architecture of a company solving high-stakes data problems for the physical economy. You will tackle real-world challenges like industrial noise and latency while defining the future of voice-driven operations.
Role overview
You will lead the development of a production-grade voice intelligence platform designed for complex, real-world environments. By bridging the gap between spoken conversation and structured data, you will build robust ASR pipelines and multi-tenant systems that solve critical operational challenges for distributed teams operating in high-noise, high-stakes physical settings.
About the company
Well-funded Voice AI startup
What you will do
- Design and deploy production-grade voice pipelines that handle real-world challenges like industrial noise, accents, and low-latency tradeoffs.
- Build an intelligence layer that decomposes complex forms into natural conversation flows and maps transcripts back into structured records.
- Develop scalable, polyglot software across the backend, frontend, and mobile to enable highly configurable workflows for a global client base.
Who this is a fit for
- Deep expertise in speech AI, NLP, or ASR with experience deploying robust, high-accuracy models in challenging production environments.
- Versatile full-stack engineering background with the ability to navigate a polyglot codebase and ship working software at high velocity.
- A founding mindset characterized by high agency, pragmatic decision-making, and a deep interest in building products that solve complex user workflows.
Why this role is remarkable
- Join as one of the first engineers to architect a voice-first platform where AI is the core product, not just a side feature.
- The company is backed by high-conviction investors and top-tier VCs, focusing on a massive untapped market within the physical economy.
- Own the entire technical stack from ASR robustness and LLM-driven intelligence to full-stack platform architecture and native mobile integration.
