ABOUT YOU

We’re looking for a Senior Software Engineer who thrives on solving complex technical challenges and building scalable systems that serve millions of users. You’re someone who enjoys working across languages and platforms, with solid backend experience in Go and a deep understanding of microservices architecture.

You’re experienced with containerized environments and orchestration platforms, CI/CD practices, and automated testing, ensuring systems are scalable, maintainable, and production-ready. You know how to architect systems that are resilient, maintainable, and scalable. You’re data-driven, collaborative, and committed to building high-impact solutions that support Xsolla’s mission to power the global gaming economy.

About The Platform Team

• Event data is at the center of Adtech architecture. This platform team is defining how we shape and transmit events across all of our systems.
• The team ensures the systems that these events cross are built with consistency, reliability, and scalability in mind, and is responsible for scaling workflows driven by these events.
• In the team, we're big users of Kafka, it's used in the majority of our streaming processing workloads.
• In terms of storage, we primarily use Postgres (for OLTP), Clickhouse (for customer-facing OLAP workloads), and BigQuery (for internal use only).
• The team is currently composed of 4 Engineers, and the majority of their work is on platform systems.
• We use Temporal to power distributed workflows across services, especially for orchestrating multi-step, event-driven processes.
• This team is NOT: IT data, data governance, and feeding data warehouses. The team is focused on delivering high-quality data within the product, providing an interface for stakeholders, and computing critical workflows at scale.

Responsibilities

• Design, build, and maintain scalable, event-driven backend systems that power the core data infrastructure used across Xsolla products.
• Contribute to the evolution of our event platform — including how events are shaped, routed, processed, and stored at scale.
• Develop services and workflows using Go, Kafka, and Temporal.
• Collaborate cross-functionally with product managers, designers, QA, and other engineering teams to deliver end-to-end solutions.
• Own critical components of the Platform architecture — especially those related to event ingestion, transformation, and delivery.
• Develop and maintain scalable microservices deployed in containerized environments (e.g., Kubernetes).
• Lead technical design discussions and architecture reviews, focusing on performance, reliability, and maintainability.
• Take ownership of workflows and services in production — including performance tuning, incident resolution, and on-call participation.

Qualifications and Skills

• 2+ years of experience with Kafka.
• 5+ years of backend experience, ideally with Go (or similar).
• Experienced with asynchronous microservices, understands distributed computing and architecture in general.
• Hands-on experience with workflow orchestration tools such as Temporal, Cadence, or equivalent.
• Understands cloud infrastructure, observability, and scaling.
• Experience working with Kubernetes, Docker, and containerized environments.
• Ability to analyze complex problems, identify root causes, and implement effective solutions.

Good To Have

• Familiarity with cloud platforms such as AWS, GCP, or Azure.
• Background in the gaming or payments industry.
