Senior Software Engineer

to creatively and collaboratively transform the cinema industry.

Unique X delivers innovative, autonomous software solutions and content services to cinemas worldwide as we draw all elements of cinema operations and content services together into a single, automated workflow.

We have a truly global reach; our products are used in over 90 different countries around the world making us the leading digital cinema solution provider and our customers include the major Hollywood and independent film studios and the largest cinema operators.

If you’ve ever been to the cinema, chances are Unique X helped put that content and the movie on the screen.

We feel, act and behave as one big team, working inclusively and collaboratively to develop innovative products by encouraging employees to share their ideas. We value each person’s talent and the contributions they bring to the organisation, giving them the motivation and tools to successfully achieve their goals.

We see a Senior Engineer as the owner of a feature from the first conversation with the Product Owner to its behaviour in production, not as someone who turns tickets into code. AI agents now write most of the code under your direction. Your value is in understanding the problem, specifying the change and judging the result.

You will join the Advertising Accord (AA) team. AA is the platform cinema advertising sales houses use to sell, schedule, play out and report on the ads shown before the film, both directly sold and programmatic, across thousands of screens.

The platform is written in Java with a serverless-first mindset and deployed on AWS. We are building the next generation of the product to support agentic workflows—both in-product and for software development—and you will work on both the current and next generation of the product.

We are an AI-first team. Developers direct AI coding agents to handle most implementation and testing, and spend their time on the problem, the specification, and the review. The constraint is no longer how fast you can type Java; it is how well you can specify, verify, and accept a change.

Trust comes from the pipeline, not the prompt. Every change, human or AI, passes the same automated quality, security, test and architecture gates, plus an independent review.

Teams are small and agile; they collaborate on all aspects of a product. You will participate in designing and verifying solutions.

Do not expect to be a screw in a big machine. You own features end to end:

• Work with the Product Owner (and at times clients) to understand the real problem, and push back when the request does not match the need.
• Write the specification and acceptance criteria the agent and reviewer work from.
• Direct the implementation, review the code as you would a colleague's, and improve the agent context and rules as you go.
• Make sure the tests prove the behaviour, not just the coverage number.
• Lead design in your area and mentor developers earlier in this shift.

A strong engineer already working this way or close to it. Can you explain a system to a product owner or an agent in plain language, then guide implementation with human judgments on code quality, architecture, user interface, and similar concerns.

• 5+ years building production software, including a role where you owned technical decisions (Senior Developer, Tech Lead or similar).
• Strong Type Script — strict typing, modern React, and Node-based services. Most new feature work is built here.
• Solid Java (17 or 21) and Spring Boot — enough to read, extend and safely change a large established codebase.
