Senior Full-Stack Developer

We are hiring a Senior Full-Stack Developer at the Centre for Collective Intelligence. The Centre for Collective Intelligence is pioneering new ways to engage the public at scale to address society’s most pressing challenges. Currently incubated within Nesta, we are transitioning into an independent organisation over the next few years, to scale our impact globally. Our mission is to transform the way society collaborates by breaking down barriers to participation, reimagining civic engagement, and rebuilding trust between people and institutions. We use technology, AI, arts and design to scale public engagement.

The role involves the maintenance of, and development of new features and AI integrations for, an internal tool called Zeitgeist, alongside other responsibilities. The development team currently follows common agile delivery practices for software development, and interacts with client projects that use Zeitgeist.

You will be responsible for:

• Quarterly product alignment workshops to plan work in support of business development, the team’s needs, and product maintenance
• Estimating and meeting feature delivery deadlines
• Estimating and meeting content implementation deadlines
• Managing CCI’s security profile and holding quarterly threat model reviews
• Keeping our data protection guidance and DPIA up to date
• Managing key hardware (tablets and a few laptops) for in‑person engagements
• Creatively using technologies at our disposal to support other team members, projects, and activities that CCI engage in
• Maintaining and managing the development team day‑to‑day processes
• Supporting growth and learning for your development team and, where applicable, the wider team
• Business development activities, providing technical input to bids and documentation
• Line management of 1 developer on your team

As the most technical person working on the product you will also be customer‑facing, at times, representing the product’s capabilities. You will be working with our current developer who can show you the ropes, and has a good working knowledge of Zeitgeist.

It’s unlikely that you’ll have experience of all the technologies outlined below, but you should have worked with a cloud‑based infrastructure (ideally AWS), and front‑end technologies (ideally React). Familiarity with at least one of the key languages we are using (ie. C# or Typescript) will set you up for success. You are a good all‑rounder, with confidence to pick up what you need from technical documentation and self‑guided learning. You’ll have a flexible, adaptable approach to using a range of different technologies to solve problems - using the right tools for each job, depending on the circumstances. A curiosity about how to harness the power of collective intelligence for social good through new products and technologies is desirable.

Your experience:

• 5+ years experience in full stack software development
• Ability to produce rapid prototypes, with a flexible approach and ability in using a range of technologies
• Cloud‑based technology (ideally AWS)
• Frontend development (ideally React with Typescript)
• One or more of the core languages we’re using (C#, Typescript)
• Relational databases (mandatory), other database types (desirable)
• Demonstrable experience of using agile project methodologies, and test‑driven development
• A BSc, or MSc in computer science, engineering, or related discipline or at least five years’ relevant experience in industry
• Demonstrated ability to work on technical tasks independently, with minimal support
• Excellent time management, and able to manage multiple projects and competing priorities
• Ability to receive, give, and act on feedback
• A self‑starter with a curious and open mindset, a willingness to learn from and with others, and ability to carry out self‑directed research and learning
• An interest in developing or integrating AI tools and functionality
• A motivation to tackle social problems, and a personal commitment to the principles of data justice and community empowerment

What we offer:

• Salary circa £75,000, plus an array of benefits, including private medical insurance, dental insurance, the ability to buy and sell annual leave, eyecare vouchers and more

Location: This role is based in Blackfriars, London, hybrid working arrangement with a minimum of two days in the office.
