Senior Product Engineer (Backend)

Why this role exists

At GOG, we build for gamers who care about preservation, community and nostalgia. Our mission is bold: make games live forever - and that requires seamless, modern experiences that resonate with today’s players while staying true to GOG’s identity.

Our challenge spans two fronts: maintain and evolve our established Store and Galaxy backend services for performance and reliability, while designing the next generation of APIs, data flows, and integrations that bring community and preservation features to life for millions of players.

We’re looking for people who want to understand the full product loop - from data pipelines and experimentation, through frontend delivery, to the player experience itself.

If you’re curious about expanding your craft into data, frontend, or product domains, you’ll find plenty of room to grow here and real projects that encourage it.

What success looks like in the first 6–12 months

• Deliver performant, maintainable PHP services and features that enable community & preservation initiatives (Dreamlist engagement, user-generated content pipelines, review/curation flows)

• Have a direct voice in product decisions – shaping not just how things are built, but what gets built to serve our mission and community best.

• Apply the scout rule: consistently leave the codebase cleaner, more efficient, and easier to maintain as you work on new features. 

• Strengthen collaboration with frontend, data and product teams by helping define clear, practical interfaces and workflows that reduce complexity in day-to-day development.

• Contribute to the evolution and consistency of our existing design system by building reusable, high-quality components aligned with it.

What you’ll do day-to-day

• Design, build, and optimize PHP services and APIs for community & preservation initiatives (Dreamlist, User Generated Content, review systems)

• Use data and experiments (A/B tests, analytics events) to validate impact and prioritize work smartly; ensure clean event contracts and reliable data flow.

• Collaborate closely with frontend, data, product, and design - shaping not just how we build, but what we build to best serve our mission and community.

• Own feature delivery end-to-end: technical discovery, implementation, code review, instrumentation, and iteration.

• Share knowledge, mentor, and raise the bar for frontend craft and product thinking.

What will help you succeed

Technical depth

• 6+ years in backend development; strong PHP, MySQL, and experience with Docker, RabbitMQ, and Kubernetes (k8s).

• 2+ years of hands-on Symfony (3.4 -> 7.4) - including Doctrine ORM and practical experience with maintaining and evolving large Symfony codebases.

• Experience working in and improving established/legacy codebases while shipping new features safely and iteratively.

• Solid understanding of software architecture and design patterns, including CQRS and Hexagonal Architecture.

• Proven experience with application caching strategies using Redis and Varnish, ensuring scalability and low-latency APIs.

• Skilled in writing integration and functional tests with PHPUnit and Behat, focusing on reliability, automation, and CI integration.

• Understanding of scalable architectures (microservices, modular monoliths) and high-availability environments.

• Comfortable with Git, CI/CD, and agile workflows; proactive in improving build pipelines and deployment reliability.

Product & mindset

• Strong product sense: you think beyond code, empathize with gamers, and care about outcomes.

• Comfortable with experimentation (A/B testing, analytics) and fast, iterative delivery.

• Balance short-term fixes with long-term code health.

• Deep expertise in backend plus curiosity to grow beyond it—whether that’s product discovery, frontend collaboration or data.

Nice to have

• Experience with online community platforms or content contribution features.

• Passion for games and game preservation.

• Active use of AI tools in daily development workflows, and enthusiasm for helping the team increase adoption.

Key challenges you’ll tackle

• Preservation projects: craft features that activate and celebrate “Make Games Live Forever.”

• Finest Editions & Preservation Program: support unique GOG editions and restoration efforts with compelling, reliable frontends.

• User-Generated Content: enable players to contribute knowledge, reviews, and value to the community.

• Store ↔ Galaxy continuity: help experiences feel connected and consistent across surfaces.

• Manage and iteratively reduce technical debt while balancing delivery of new, modern solutions.
