Gaming:

Welcome to the world of land-based gaming. At Light & Wonder, it’s all about the games, and our Gaming team builds cutting-edge technology, products, and content for the most iconic casinos and operators across the globe.

Position Summary

We pride ourselves on creativity, collaboration, and technical excellence. We balance ambitious delivery with a friendly, connected studio culture, including regular social events, team nights out, board-game evenings, and more.

This is an exciting opportunity for an experienced Senior Software Engineer to join a multidisciplinary team of engineers, artists, designers, and mathematicians developing market-leading gaming content for a global audience.

You'll play a key role in designing and developing high-quality game software using Unity, contributing to the full development lifecycle from concept through to release. Alongside hands-on development, you'll support junior engineers, share technical expertise, and help drive engineering excellence across the team.

This role is ideal for an experienced Unity developer with strong programming foundations, a collaborative mindset, and a passion for creating engaging player experiences.

Work Pattern: This role is based in our vibrant Manchester studio and requires attendance 4 days per week. Regular on-site working is essential because the role involves developing, testing, and troubleshooting software directly on our gaming machines and specialist hardware.

Celebrate Perspectives – You will collaborate with developers, artists, designers, producers, and specialists who bring different skills and viewpoints to every game.

Win as a Team – You will support others, share knowledge, and help the wider team deliver exceptional outcomes together.

  • Participate in code reviews, sharing constructive feedback and helping maintain quality across the codebase.

  • Support and mentor junior engineers, providing technical guidance and encouraging professional development.

  • Contribute to continuous improvement initiatives, identifying opportunities to enhance development processes, tools, and engineering practices.

  • Share knowledge across the team and help foster a collaborative, high-performing engineering culture.

What You'll Bring

  • Commercial experience developing software in C++, including the ability to understand, debug, and maintain complex codebases.

  • Experience developing games using the Unity game engine.

  • Strong capability in C# and object-oriented programming principles.

  • Excellent programming knowledge supported by solid software engineering fundamentals.
