Staff / Senior Software Engineer at Super… · Croatia

We are on a mission to pioneer the world’s next era of play. As we grow across Europe and Latin America, we’re building The Playstack - the technology powering the next generation of sports, gaming, and fan experiences. Join us, and help make it the most widely used platform in the world! From operations, to marketing, to product, we are looking for talented people who will shape how millions of customers play, watch, and connect every day. The Gaming Integrations team operates approximately 26 provider integrations across three runtimes and is the critical path for Super entering new markets. This is a key capacity hire into a small, high-impact team, with immediate contribution expected across two strategic priorities: rebuilding the game platform into a scalable, multi-studio architecture, and accelerating integration delivery to support new country launches. You will have real ownership, high visibility, and direct influence on the team's technical direction.

What the role involves

Elixir Platform Migration

• Contribute to the migration of Node.js/Erlang integrations to the new Elixir-based platform, where feature parity across runtimes is a current blocker for multiple localisations

Game Studio Integrations

• Own the full lifecycle of new provider integrations (launchUrl, authenticate, balance, debit, credit, void), from implementation through to production sign-off

Platform Architecture

• Implement CI/CD pipelines, shared services, and the modular architecture required to support multiple exclusive gaming studios at scale

Operational Excellence

• Maintain KTLO (keeping the lights on) under 10% of team capacity whilst sustaining high availability across all 26+ live integrations

Project Impact

• Lead larger projects or small squads, run meetings, write status reports, and track delivery
• Proactively identify problems and drive resolution, often without guidance
• Demonstrate impact clearly through metrics, not just activity

Engineering Excellence

• Take end-to-end ownership of product quality: reliability, efficiency, security, and performance
• Drive engineering efficiency improvements across the organisation (faster onboarding, better tooling, reduced cycle time)
• Become the established go-to owner of at least one component or system with expert depth

Communication & Collaboration

• Build working relationships cross-functionally across product, SRE, QA, integration managers, and gaming studios
• Give detailed, specific positive and constructive feedback to the Tribe Lead and teammates
• Facilitate fast learning cycles and nurture innovation within the team

Organisational Impact

• Actively mentor less-experienced engineers and create conditions for them to grow
• Participate in recruiting and interviewing, with a particular focus on diversity recruiting
• Onboard new team members and make codebases easy to ramp up on
• Invest in your own skills and bring new knowledge back to the team (currently relevant: Elixir, Kafka operations, distributed systems at scale)

What we are looking for

• 5+ years building high-quality software with strong engineering practices (code reviews, CI/CD, design documentation)
• Proven track record of unblocking yourself and driving improvements across a team (high agency)
• Experience with microservice and event-based architectures
• Experience with Kafka
• Experience building highly available, highly scalable, distributed backend systems
• Proficiency in Node.js / TypeScript
• Hands-on experience with Kubernetes, Docker, and AWS
• Experience working cross-functionally in product organisations alongside product managers, designers, and stakeholders
• Strong sense of ownership, problem-solving instinct, and clear, direct communication
• Product engineer mindset — understands business context, not purely tech-focused

Nice to have

• Experience operating Kafka in production
• Elixir or functional programming experience (our strategic direction)
• Experience in the betting or gaming industry

What we offer

• Medical / Health Insurance
• Open Annual Leave
• Employee Assistance Programme
• Training & Learning Development

Additional benefits vary by country and will be shared during the hiring process.
