The Problem You'll Help Solve * ensuring complex technologies remain transparent and accountable * helping organisations adopt AI safely and responsibly * building governance systems that support innovation rather than slow it down. ## Description The purpose of this role as Senior Full Stack Engineer is to design and ship end-to-end features across our AI governance platform - from a scalable Python backend on AWS through to the TypeScript/React front-end that gives users clarity and control. this is a hands-on, high-impact individual-contributor role at the centre of a fast-moving start-up: you'll own features from concept to production, make pragmatic architectural decisions, and translate complex, governance-led product thinking into a platform that is scalable, secure and trustworthy for the business customers who rely on it. You will report to the Director of Technology and work in close, day-to-day collaboration with the Lead Developer, the UI/UX Lead and the wider engineering team - pairing engineering and design closely together to underpin the rapid launch and development of our AI-native service. You'll be joining early enough to shape not just the platform, but how engineering happens., The Senior Full Stack Engineer role sits at the intersection of backend, front-end and AI-augmented delivery. You will take features from concept through to production, working across three areas: a scalable Python backend on AWS, harness-based AI-assisted development workflows, and a TypeScript/React front-end that gives users clarity and control over the platform., * Design, build and ship full-stack features - a scalable, secure Python backend on AWS and a polished TypeScript/React front-end. * Work hands-on with our cloud infrastructure (Terraform, Kubernetes, EKS) to deploy and operate the services you build or similar coding agents in automated loops to handle the majority (80%+) of the SDLC, from planning through implementation, testing, and review. * Partner closely with the UI/UX Lead to turn designs into responsive, accessible, high-quality interfaces. * Uphold engineering standards: code quality, CI/CD, testing, and release practices. * Contribute to technical direction and roadmap discussions with the Director of Technology and founders. * Use AI tools throughout your own workflow - for planning, coding, testing and review - to accelerate delivery without compromising quality. * Continuously look for better ways of working - in your process, your tools and your output ## Related Videos - [Infrastructure as Code: The Developer's Secret Weapon](https://www.wearedevelopers.com/videos/1221-infrastructure-as-code-the-developer-s-secret-weapon) - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Why Your Best Mediors Never Become Seniors (And How to Fix It)](https://www.wearedevelopers.com/videos/2108-why-your-best-mediors-never-become-seniors-and-how-to-fix-it) - [Implementing Feature Environments with AWS and Terraform](https://www.wearedevelopers.com/videos/531-implementing-feature-environments-with-aws-and-terraform) - [Inside Bitpanda's Tech Stack: Scaling a European Fintech Leader - Markus Dorner](https://www.wearedevelopers.com/videos/1979-inside-bitpanda-s-tech-stack-scaling-a-european-fintech-leader-markus-dorner) ## Related Articles - [Fullstack Developer Salary UK](https://www.wearedevelopers.com/magazine/251-fullstack-developer-salary-uk) - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [How to Become an AI Engineer](https://www.wearedevelopers.com/magazine/331-how-to-become-an-ai-engineer) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated)
