Full Stack Developer

Join a product team to help deliver critical deadlines where additional capacity is needed. You'll work hands-on across the stack using TypeScript, React and Node.js (Express), using AI-assisted development tools as part of your day-to-day workflow. You'll take ownership of small, clearly defined, high-volume tickets that unblock wider delivery, working within a domain-driven team under experienced engineering leadership. You'll build and extend services on AWS with MongoDB, working within a monolith or modular MVC-style architecture and established CI/CD pipelines (Bitbucket, Jenkins). You'll write well-tested code and help raise the bar on testing within the team. Why this role You'll be expected to contribute quickly within a live system, getting up to speed and delivering value within days, not weeks. Work is broken down into small, well-defined tasks to maximise delivery speed and reduce ambiguity. You'll work under experienced team leads with clear direction, within a team already using AI-assisted workflows and evolving its testing approach. This is a focused engagement designed to increase delivery capacity without disrupting existing teams. Who is hedgehog lab We're an outcome-driven product consultancy where product, design, engineering and research sit side by side. You'll join a team focused on building impactful products through collaboration and strong engineering practices.
