Immersive is hiring! Could you be our next Software Engineer?
Join our established UK Engineering team as an Associate Software Engineer. We are looking for someone curious, eager to solve problems, and excited to build alongside a collaborative team.

Reporting to one of our Engineering Managers and based in our Bristol office, you will be a key part of building our Immersive One platform. You’ll join a team where we value determination, ingenuity, and pragmatic, reusable technical solutions.

You’ll work within a multi-disciplinary agile team, focusing on quarterly outcomes that drive real impact. We rotate our teams to keep things fresh and encourage cross-pollination of skills, and you’ll also have the chance to explore innovative ideas during our twice-yearly Hack Weeks.

You will be instrumental in shaping the future of our product, working across our entire system landscape. Our tech stack includes:

Backend:
Ruby on Rails, Node.js and Python

Frontend:
React and Type Script

Testing:
Playwright and Type Script

This role is ideal for someone early in their commercial software development journey who has the motivation to become a well-rounded full-stack engineer. We appreciate that early in your career, you may not have a fully formed view of your preferred direction; here, you will gain hands‑on experience across the entire stack.

As an individual contributor in the team, your main responsibilities will include:

• Work alongside the team to design, build, and maintain an efficient, reusable, and reliable codebase across the stack.
• Collaborate with Product Managers and other disciplines to help translate requirements into technical solutions.
• Partner with our Quality Experts to deliver automated tests, ensuring we have confidence in every feature we release.
• Contribute to the team's success by fixing bugs, resolving incidents, and minimizing customer impact.
• Help ensure code quality by sharing feedback with your peers via our code review process.

Success in this role will depend most on your approach, underlying skills, and potential for growth. You don’t have to match all the listed requirements below exactly to be considered, so we encourage you to apply even if some of them would be new to you.

Sounds good? We’d love to hear from you if you have proven experience in the following areas:

• 1–2 years of commercial experience building customer facing web applications or working on SaaS platforms.
• You consider accessibility in all aspects of your work
• Experience using AI tools to accelerate development and problem‑solving.
• You are willing to work with different programming languages across our tech stack ( Ruby, Python, React, Type Script, or Node.js) as needed.
• Proficiency with Git and familiarity with Git Hub actions.
• Experience working in agile cross functional teams and working independently and pro‑actively
• Takes pride in code quality by testing features thoroughly and offering helpful, supportive feedback during peer code reviews.
