Your new company This rapidly growing SaaS technology business has established itself as one of the UK's leading B2B software success stories. Combining the agility of a scale-up with the stability of a profitable, privately owned organisation, the company has built an engineering-first culture where technology investment remains a core strategic priority.

You'll work closely with stakeholders on solution design, requirements gathering and architecture decisions, helping shape products from concept through to deployment.

The role sits within a modern TypeScript environment utilising Node.js microservices, Vue, Redis, SQL Server and SingleStore, all deployed within AWS following DevSecOps principles. Engineering teams deploy to production daily and take ownership of the products they build throughout their lifecycle. The organisation is investing heavily in next-generation product capabilities, particularly around AI-driven development and Agentic AI.
