Referment is working with an AI-powered B2B marketing technology company whose platform personalises content, tracks account engagement and supports sales activity across the buyer journey.

This is a product-engineering role with ownership from customer problem through architecture, implementation and iteration. You will work across backend services, web interfaces, event infrastructure and AI-powered features, collaborating directly with Product, customers and commercial teams to decide what should be built as well as how to build it. The role is available on a hybrid London basis or remotely.

The Role

• Lead product problems from an ambiguous customer need through design, delivery and iteration.
• Build Go services and TypeScript, React and Next.js interfaces used by enterprise marketing and sales teams.
• Develop AI-powered functionality for content generation, account intelligence and campaign automation.
• Design scalable event pipelines, identity resolution, CRM synchronisation and integration infrastructure.
• Work with Kafka, Postgres, Redis and BigQuery across AWS and GCP environments.
• Partner with Product, customers and go-to-market teams to shape priorities and evaluate commercial outcomes.
  
  

What We’re Looking For

• A product-minded engineer who focuses on solving the right customer problem across the stack.
• Experience leading projects from an unclear brief to a production release, ideally in a startup or fast-moving product team.
• Production experience in at least one of Go, TypeScript and React, or cloud infrastructure on AWS or GCP, with willingness to learn the rest.
• Comfort making decisions without a detailed specification and taking responsibility for the result.
• Clear written and verbal communication with technical and non-technical colleagues.
  
  

Experience with high-volume event systems, CRM integrations, data infrastructure or production AI features would be particularly relevant, but the source does not require every technology listed.

This could suit a strong full-stack, backend or product-focused engineer who wants direct customer context and end-to-end ownership rather than narrowly defined tickets.
