Full Stack Developer (Python) - SC Cleared

Hybrid - 2 Days per Week Onsite in Leeds

We're supporting a secure-sector organisation seeking an experienced Full Stack Developer with strong Python expertise to join a high-performing engineering team. This role is ideal for someone who enjoys solving complex problems, shaping scalable solutions, and contributing to a collaborative, modern technical environment.

You'll work across the full development life cycle - designing, building, and maintaining high-quality applications - while helping to guide best practices and support junior engineers. This is a great opportunity to make a meaningful impact within a mission-driven setting where engineering excellence is valued.

What You'll Be Doing
  • Designing and developing high-quality, scalable software using modern Python frameworks.
  • Contributing to Front End development using JavaScript and contemporary UI technologies.
  • Building and optimising SQL-based data solutions.
  • Working with cloud technologies and infrastructure-as-code tooling.
  • Creating automated, test-driven, and secure solutions that follow industry best practice.
  • Collaborating closely with cross-functional teams to deliver effective, reliable products.
  • Supporting and mentoring junior developers to promote continuous improvement.

What We're Looking For

  • Active SC Clearance (mandatory).
  • Strong commercial experience with Python and modern Back End frameworks.
  • Confident working across the full stack, including Front End tooling.
  • Experience with cloud services (AWS preferred) and containerisation.
  • Knowledge of SQL and database optimisation.
  • Solid understanding of software design principles and development best practices.
  • Strong communication skills, with the ability to work effectively with both technical and non-technical teams.

Location & Working Pattern

  • 2 days per week onsite in Leeds (non-negotiable due to project requirements).
  • Hybrid/flexible working for remaining days.

Why This Role?

You'll join a supportive, forward-thinking environment where you can influence technical direction, shape modern engineering practices, and work on meaningful projects that contribute to critical national-level outcomes.
