## About the Role

* Around 5-10 years' full-stack software engineering experience, ideally backend-leaning
 * Meaningful hands-on experience building and shipping AI products end-to-end
 * Strong experience with agentic systems, rather than purely general ML or Data Science
 * Early-stage startup experience, ideally Series A or earlier
 * Experience working directly with customers and non-technical stakeholders
 * A Computer Science degree

Technical skills

 * Strong full-stack proficiency in Python and/or TypeScript
 * Excellent async Python experience in production environments
 * Hands-on experience with async coroutines, httpx and AsyncOpenAI
 * Strong understanding of production-grade error handling in asynchronous systems
 * Experience with modern cloud infrastructure including Kubernetes, serverless and distributed systems
 * Experience with Voice AI, event-driven systems and/or CRM integrations

You'll probably thrive here if...

You enjoy the ambiguity, pace and ownership that come with an early-stage startup, rather than needing highly defined structures and narrowly scoped responsibilities.

You're a product-minded engineer and builder, not someone focused primarily on research, traditional ML or Data Science.

And importantly, you must be able and happy to work 5 days per week onsite in London.

## Description

* Build and ship AI products end-to-end, from identifying the problem through to production
 * Develop agentic and Voice AI systems used by real customers
 * Build across Python, TypeScript, APIs, event-driven systems and cloud infrastructure
 * Work directly with customers and non-technical stakeholders to understand problems, scope solutions and deliver outcomes
 * Build integrations with third-party platforms and CRM systems
 * Help shape technical standards, architecture and product direction as the engineering team grows
