Senior Software Developer - £100k - Discretionary Bonus - Hybrid
 
Overview
We are partnering with a global digital marketing and technology agency specialising in online gaming to hire a Senior Software Developer. In this senior role, you’ll take technical ownership of solutions end-to-end, mentor junior developers, and ensure delivery of highly scalable, high-availability platforms that drive cutting-edge online gaming experiences.
 
You’ll also play a senior position in driving the move from a PHP-heavy stack to a modern TypeScript/React front end, helping define and deliver greenfield solutions with a premium, customer-first focus.
 
Role and Responsibilities

Drive full-stack development projects, ensuring high-quality delivery across both frontend and backend.
Act as a technical lead for React/TypeScript adoption, mentoring the team (currently PHP-heavy) and raising overall capability.
Architect and implement scalable, performant solutions that power high-traffic, real-time platforms.
Take ownership of key greenfield projects, shaping the technical direction for premium UI/UX.
Collaborate with cross-functional teams to align technical solutions with business goals.
Support DevOps and CI/CD initiatives where possible. 
Essential Skills and Experience

Proven experience with PHP (backend) and TypeScript/React (frontend).
Track record of leading or mentoring in engineering teams.
Experience building greenfield projects (not templated CMS like WordPress).
Familiarity with Node.js/NestJS is desirable but not essential.
Strong understanding of design patterns, scalability, and system performance.
DevOps experience (Docker, AWS, CI/CD pipelines) would be highly valued.
Strong database expertise (MySQL and diverse storage paradigms).
Nice to have: Prior experience in the iGaming industry or similar complex transactional platforms.
