About the Role

We’re looking for a Software Engineer who wants to do more than just work through tickets. This role offers the opportunity to work across the full stack, contribute to real production systems, and grow quickly within a high-impact engineering team. You’ll be joining a fast-scaling business where engineering is a top priority, working closely with teams across London and internationally to deliver meaningful outcomes.

This is an exciting opportunity to join a team that has recently gone through significant growth, offering you the chance to learn from experienced engineers and contribute to a modern cloud-based platform. You’ll be working in a culture that values ownership, pragmatism, and continuous improvement. The environment is fast-paced but highly collaborative, and you’ll have the chance to make a meaningful impact early on.

Key Responsibilities

In this role, you will build and maintain backend services and APIs using Python frameworks such as Django or FastAPI, while also developing modern, responsive frontend experiences using React and TypeScript. You’ll take ownership of features from design through to deployment and iteration, ensuring that your work delivers real value to end users. Alongside feature development, you will play a key role in improving system reliability, performance, and scalability by identifying bottlenecks, optimising queries and services, and contributing to performance improvements across the platform.

You will work within a cloud-based environment, collaborating on deployments, CI/CD pipelines, and infrastructure improvements, gaining exposure to the full software lifecycle. You will also be responsible for debugging issues across the stack, supporting production systems, and contributing to root cause analysis when problems arise. A key part of the team’s approach is leveraging AI-assisted development tools such as Copilot, Cursor, or Claude, and you’ll be expected to actively use these tools to improve productivity, code quality, and learning.

Skills & Experience

We’re looking for someone with solid commercial experience in software engineering and a track record of contributing to production systems in a professional environment. You should have strong foundations in either backend or full stack development, ideally with hands-on experience in Python and a modern JavaScript framework such as React. You will be comfortable working with RESTful APIs, understanding application architecture, and writing clean, maintainable, and testable code.

Experience working within cloud environments such as Azure, AWS, or GCP is highly desirable, along with some exposure to CI/CD practices, version control, and modern development workflows. You should demonstrate a willingness to learn new technologies and work across different areas of the stack, with a problem-solving mindset and a pragmatic approach to engineering. We are particularly interested in candidates who are already using, or actively adopting, AI-assisted development tools as part of their day-to-day work, as this is becoming an integral part of how the team operates. Strong communication skills and the ability to collaborate effectively in a cross-functional and distributed team are also essential.
