Senior Developer - Oxford based

Hi, we’re Super Benji! We're Oxford’s fastest-growing AI startup, just over 1.5 years old and building a category-defining sales automation platform. We help businesses supercharge outbound sales by combining hyper-personalisation, AI, and a lot of human love, delivered through automation. We've seen incredible traction with our no-code-first approach, built by a small team of junior developers. Now, we’re ready for the next chapter: transforming our no-code systems into robust, scalable products — and we need a Senior Developer to help us get there. The opportunity We’re looking for a more senior developer with a solid foundation in computer science, experience with no-code platforms, and an eye for scalable system design. You’ll work closely with both local and remote developers to enhance, extend, and strengthen our AI-driven platform. You’ll also play a pivotal role in shaping the technical future of Super Benji — bringing in best practices, mentoring the team, and turning our MVPs into world-class products. Some of the things you'll be doing: Building out our core infrastructure, transitioning validated no-code tools into robust coded systems where needed. Integrating the latest AI tools into new products and internal automations. Designing and implementing scalable, secure, and maintainable software architecture. Collaborating with stakeholders across product, sales, and ops to prioritise and deliver impactful features. Mentoring junior developers and establishing best practices in code quality, testing, and documentation. What we're looking for: 4 years of professional experience in software development. Experience to supervise and guide junior developers. Passion for AI and automation, with a curiosity for emerging tools and technologies. Strong background in computer science fundamentals (data structures, algorithms, system design). Experience with no-code/low-code platforms and the ability to navigate them fluently. Experience with cURL, Postman or Swagger. Solid programming skills in C#, Python and JavaScript/TypeScript. Experience building and integrating APIs. Knowledge of cloud platforms (e.g. Firebase, AWS, GCP) and DevOps tools is a big plus. A builder’s mindset — ready to ship fast, learn, and improve continuously. Great communication skills and a collaborative, mentoring approach to teamwork. Why join us: Shape the future : Help build the future of sales from the ground up at a high-growth AI startup. Cutting-edge tech : Work at the frontier of AI, automation, and human-centred design. Real ownership : You’ll have influence, autonomy, and the opportunity to grow with the business. Fun mission-driven : We’re serious about impact, but we do it with heart, humour, and a dog-loving spirit. Join the pack: At Super Benji, we’re rethinking how humans and machines work together.
