About the role

We're looking for a Lead Node.js Engineer (Architecture) - CMS who enjoys solving complex technical challenges and wants to make a real impact on a high-scale platform.

This is a hands-on technical leadership role, where you'll combine software architecture with active development. You'll lead the design and evolution of our CMS platform and backend services, make key architectural decisions, and work closely with other engineers to build scalable, reliable, and high-performing solutions.

You'll play a central role in shaping our backend ecosystem—improving platform resilience, designing efficient data flows, and ensuring our systems can scale as the business grows. Working across engineering and product teams, you'll help turn technical vision into robust, production-ready solutions while staying close to the code and mentoring those around you.

All the responsibilities we will trust you with:

• Lead technical and architectural discussions, translating business needs into scalable backend solutions.
• Design, build, and maintain secure, high-performing backend systems, with a strong focus on hands-on development.
• Drive architectural decisions, coding standards, and engineering best practices to ensure high-quality, maintainable code.
• Develop and maintain APIs, backend services, and system integrations that power reliable, scalable applications.
• Own code quality through testing, debugging, performance optimisation, and technical reviews.
• Collaborate with engineers and cross-functional teams to improve platform resilience, system performance, and delivery.
• Enhance CI/CD pipelines, deployment processes, and production support to enable faster, more reliable releases.
• Identify and implement architectural improvements that support the long-term evolution of the platform.
• Explore and champion modern engineering practices, including AI-assisted development tools, to boost developer productivity and delivery efficiency.

Your areas of knowledge and expertise :

• Experience with Content Management Systems (CMS), including greenfield development, content modelling, migrations, and re-platforming to modern solutions.
• 7+ years of backend development experience (Node.js or similar), including senior or lead roles with ownership of architecture and technical design decisions.
• Deep understanding of modern backend engineering practices, with experience building scalable, high-availability systems.
• Hands-on experience with Node.js and its frameworks such as Express.js, NestJS, or similar.
• Proven track record designing REST APIs, microservices, and integrations with frontend and backoffice systems.
• Solid experience with databases such as SQL, MongoDB, or Redis, including data modelling, optimisation, and performance tuning.
• Good understanding of event-driven and asynchronous architectures, as well as API performance best practices.
• Experience working in Agile environments (Scrum or Kanban).
• Familiarity with AI-assisted development tools (e.g. Claude Code, Cursor, OpenAI Codex) is a strong plus.
• Strong problem-solving skills with the ability to troubleshoot and resolve complex cross-system issues.
• Clear communicator, able to explain technical decisions to both technical and non-technical stakeholders.
• Comfortable taking ownership and driving work independently in a collaborative team environment.

Nice to have:

• Experience in the iGaming industry
• Experience with cloud platforms (Google Cloud, Azure)
• Experience with containers (Docker, Kubernetes)
• Experience with PHP (Symfony)
