SUMMARY:
We are looking for a Mid-Senior Full Stack JavaScript/TypeScript Engineer to join a Commercial Engineering team working on business-critical digital publishing and advertising platforms.
This is a long-term opportunity within a complex, high-traffic production environment, combining ongoing platform enhancement, modernisation and migration work. The role is technically full stack, with an approximate 70/30 frontend-to-backend split, although the frontend work is focused on browser-level engineering rather than traditional UI or React component development.

- Develop and maintain software using JavaScript, TypeScript and Node.js.
- Working directly with vanilla JavaScript, the DOM and browser APIs.
- Building and maintaining plugin and configuration systems.
- Working with third-party script integrations across commercial and advertising platforms.
- Contributing to browser-level functionality, including DOM manipulation, scheduling and brokers.
- Working with analytics and consent management (CMP) integrations.
- Contributing to the ongoing development and modernisation of high-traffic production platforms.
- Supporting a mixture of BAU enhancements, platform evolution and migration work.
- Working within existing CI/CD, containerised and Kubernetes-based environments.
- Collaborating with an experienced engineering team to solve technical problems and deliver reliable, maintainable solutions.
- Taking ownership of problems and using initiative to identify and implement effective solutions.
WHAT WE ARE LOOKING FOR:
- Strong commercial experience with JavaScript and TypeScript.
- Strong hands-on experience with Node.js.
- Proven experience working with vanilla JavaScript.
- Strong familiarity with the DOM, browser APIs and the inner workings of modern browsers.
- Strong software engineering fundamentals.
- Experience developing and supporting software in production environments.
- Comfortable working with CI/CD and containers.
- Familiarity with working in a Kubernetes environment.
- Strong problem-solving skills and the ability to use initiative.
- Comfortable working across both frontend and backend areas of a system.
- Ability to work effectively within an established engineering team and complex production environment.
- Strong focus on code quality, maintainability and engineering best practices.
- Strong verbal and written communication skills in English
NICE TO HAVE:
- Experience with CSS and browser layout.
- Previous experience within digital publishing, advertising technology or high-traffic web platforms.
- Experience with third-party script integrations.
- Exposure to analytics platforms.
- Experience with Consent Management Platforms (CMPs).
- Experience contributing to platform modernisation or migration projects.
- Good use of LLM/AI tooling as part of the software development workflow.
