- The role: Scala Engineer
- Location: Krakow
- Contract Type: Perm or B2B
Our client operates sports betting in 18 U.S. jurisdictions and has partnerships with the biggest leagues and media companies in the U.S. Marking a major milestone in American sports history, they opened the first-ever sports betting venue within a professional United States sports facility. Partnerships like this are positioning our business to skyrocket as sports betting continues to expand across the country and our customers get a taste of the action.
On the technology side, they’ve built an entire sports betting and iGaming platform from the ground up in less than 3 years. Through continuous improvement and data-informed product development, they are adding features so that our customers have the best product experience in the market. The Product Technology team gives the team the freedom to deliver without constantly seeking permission to take action.
Main tasks:
- The team you will join builds the core of the sports betting portal that currently operates in 9 US states. It’s the heart of the new platform to enable further US expansion. The system is complex both from a functional and non-functional perspective
- You can bring your engineering expertise to contribute to all phases of the development lifecycle, as the team owns the product engineering from the design phase to the production deployment
- This will involve writing well-designed, testable, efficient code, ensuring designs comply with the specifications. You will also prepare and produce releases of software components (no worries, we have really good automation here) and support continuous improvement by investigating alternatives and technologies, and presenting these for architectural review
- You will have a chance to work with a fairly modern technology stack: (functional) Scala / JavaScript / Kafka / Cassandra / Redis / Gitlab CI / Kubernetes / Istio / Terraform / AWS / Spark / Airflow / Snowflake, and see how we approach functional programming, QA automation, event-driven and event-sourcing architectures, CQRS, and Domain-Driven Design
- You will work in Agile
Requirements:
- 3+ years of experience in backend development, with at least 2 years working with Scala in production.
- Strong knowledge of functional programming principles and practices.
- Experience with real-time systems, high-throughput APIs, and low-latency data processing.
- Familiarity with distributed systems, microservices architecture, and message queues (e.g., Kafka, RabbitMQ).
- Proficiency in working with databases, both relational (e.g., PostgreSQL, MySQL) and non-relational (e.g., Cassandra, Redis).
- Hands-on experience with cloud platforms (e.g., AWS, GCP) and containerization tools (e.g., Docker, Kubernetes).
- Strong problem-solving skills with a focus on delivering clean, maintainable code.
