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.
WHAT WILL YOU BE DOING:
As part of an agile software development team, you will:
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.
