SUMMARY Tussell is seeking a full-stack engineer to join our internal engineering team. This is an influential role, offering the successful candidate the chance to join a new team at a pivotal time and have a significant impact on a growing business. You will take part in transitioning our external development model to an in-house team during the first half of 2026, whilst setting engineering best practices. The role also offers the opportunity to take part in hiring and growing the team. There is a huge opportunity to help us unlock the full potential of our market-leading data. We’re facing exciting technical challenges - from re-architecting our data pipeline, to enabling users to query and interact with complex datasets intuitively, and scaling how we acquire entirely new swathes of data. We also believe Tussell is uniquely positioned to apply machine learning and algorithmic approaches in ways that genuinely add value — surfacing insights, improving search and discovery, and making market intelligence dramatically more accessible. The ideal candidate will have strong experience with any or all of Ruby on Rails, Python, PostgreSQL, and React, along with a track record of working with live, data-heavy applications. As a senior hire, you will collaborate closely with the product team and other key stakeholders to ensure that technical decisions support business objectives, user needs, and long-term product vision. Over time, you’ll play an influential role in evolving our architecture and infrastructure, ensuring Tussell takes full advantage of the best tools and technologies for a modern, data-driven product. Our ideal candidate may not exist. Please consider applying if you think you can contribute in this role despite not having experience in every area we have identified - we’re looking for a Tussell person first and foremost, and skill gaps can be addressed with personal development plans. ABOUT TUSSELL Founded in 2015, Tussell is a founder-led and investor-backed tech scale-up based in London. Tussell's product vision is to power better commercial decisions about the UK public sector. We offer a subscription-based online market intelligence service, which works by collating open data on public contracts and expenditure and transforming it into decision-ready data. This intelligence helps companies to do more business with the government and helps public bodies make smarter procurement decisions. Over the last decade, Tussell has become the market’s trusted source by being data-first with our competitive edge expressed through the richness and reliability of our data. THE ROLE Goal: We’re looking for a versatile self-starting engineer who can work across our entire technology stack, from backend services to user-facing applications. Someone who can set standards of good practice, not just follow them. Someone who can add to our technical know-how. Backend Development Design, develop, and maintain robust APIs and backend services using Ruby on Rails Build and optimize data processing pipelines and automation tools using Python Implement scalable service-based architecture and integrate with third-party services Ensure code quality through comprehensive testing, code reviews, and documentation Understand and refactor legacy code while maintaining feature velocity Frontend Development Develop responsive, interactive user interfaces using React and modern JavaScript Collaborate with UX/UI designers to implement pixel-perfect, accessible designs Optimize frontend performance and ensure cross-browser compatibility Build reusable component libraries and maintain design systems Release
