Job description

We’re the world’s leading sports technology company, at the intersection between sports, media, and betting. More than 1,700 sports federations, media outlets, betting operators, and consumer platforms across 120 countries rely on our know-how and technology to boost their business.

Job Description

ABOUT US:

The Sports Data & Odds Engineering organization is responsible for developing, delivering, and operating a broad portfolio of products that power Sportradar's global sports data and betting ecosystem - processing millions of real-time events every day for media companies, sports federations, betting operators, and consumer apps across 120 countries.

Working closely with rights holders, media organizations, and betting partners, our teams build and maintain highly scalable systems that support the collection, processing, analysis, and distribution of sports data and odds across more than 30 sports disciplines, including e-sports.

The development teams based in Warsaw contribute to multiple products and initiatives across these domains, building distributed systems that operate at global scale, process millions of events daily, and deliver mission-critical services that are available 24/7.

THE CHALLENGE:

This is a role for an engineer who wants to own things - not just deliver them. You will take complex technical initiatives from design through to production, work across a high-performing distributed team, and have real influence over the architecture and practices of a platform used by millions of people every day. The problems here are not manufactured. They are the kind that come from operating at genuine scale in a real-time, mission-critical environment.

Key Responsibilities:

• Design, build, and operate scalable, high-performance Java services for sports data and betting products running 24/7
• Take independent ownership of complex technical initiatives from initial design through to production delivery
• Contribute to cloud-native architecture on AWS, bringing experience and judgment to decisions that affect the whole platform
• Mentor engineers around you - through code review, pairing, and the kind of feedback that actually helps people grow
• Drive improvements to code quality, test coverage, engineering practices, and team standards
• Collaborate with product and engineering leadership on technical direction - and push back constructively when it matters
• Build expertise in one of the most technically demanding real-time data environments in the industry

ABOUT YOU:

You are an experienced engineer who can independently design, build, and operate complex software systems. You enjoy solving challenging technical problems, mentoring teammates, and influencing engineering decisions beyond your immediate deliverables.

Required:

• You have 5+ years of professional software development experience with strong Java expertise
• You can design and deliver distributed systems in production, and you understand what it takes to keep them running
• You take ownership of complex initiatives independently - from architecture decisions to post-incident reviews
• You mentor others naturally and perform technical reviews that are direct, constructive, and useful
• You have a deep understanding of testing strategy, CI/CD, and what engineering excellence looks like in practice
• You communicate clearly with technical and non-technical stakeholders and know how to land a difficult message
• Experience with AWS, Kafka, Kubernetes, and microservices at scale is a strong advantage

OUR OFFER:

• A collaborative environment with colleagues from all over the world (Engineering offices in Europe, Asia and US)
• Ability to shape your own workday and career via a clearly defined professional and personal development plan
• Opportunity to work with senior leadership team and develop yourself within an inspiring and fast-growing company
• Vibrant and inclusive community, including Women in Tech and Pride groups which welcome all participants

We believe great products are built by great teams working closely together. While we offer flexible working hours, this role is fully office-based, as we strongly value in-person collaboration, knowledge sharing, fast decision-making, and team connection. We see working together onsite as a key driver of innovation, learning, and success.
