Location: Cardiff (1 day a week in the office)
Hours: 35-hour week, flexible around life
This is a mid-level, hands‑on engineering role and is ideal for someone who wants to stay close to the code, build complex systems, and work with genuinely modern tech.
The team has rebuilt its platform into hundreds of AWS services, now transitioning from a serverless to an always‑on architecture that supports 24/7 global customers and enables faster response times. You’ll join a small, stable group with a chance to help shape standards, tools, and technical direction alongside experienced engineers who care about doing things properly.
What you’ll be doing
* Building and maintaining AWS‑based microservices (Python / Node)
* Developing new data‑driven features and public‑facing APIs
* Optimising always‑on services for latency and reliability
* Working on React components, authentication and SSO
* Contributing to AI automation projects (defect detection, QA, data grading)
* Collaborating across backend, frontend, data and security
Tech environment
* Python/Node, React
* AWS serverless architecture (Lambda, EC2, S3, CloudFormation, Bedrock), DynamoDB/SQL
* Event‑driven architecture, CI/CD pipelines, automated testing (Cypress / Playwright)
Experience needed
* Proven experience as a Software Engineer
* Solid knowledge of at least one core language (Python or Node)
* Experience with serverless architecture in AWS or Azure
* Someone who enjoys solving real engineering problems, not just writing features
* Collaborative, pragmatic, and curious about how things work
* Real AI in production – not theory, not POCs
* Broad technical exposure across architecture, data, and automation
* Freedom to contribute ideas and influence how things are built
* Supportive, experienced leadership – no politics, no burnout culture
Other
* 1 day a week in Cardiff, flexibility for life, proper kit, real balance!
* You must be able to get to Cardiff at least one day a week and possibly for townhalls/product kickoffs – this must be taken into consideration when applying.
This isn't a fast track to Senior or Principal, and that's the point. If you're happiest when you're building, learning, and making systems better every week, this team will feel like home.
