Senior Backend Engineer (Platform Tribe)

About the Role

Playson is a globally recognised iGaming supplier delivering a high-performance, microservices-based platform designed to process billions of financial transactions every day. Built across multiple regions, our infrastructure is focused on one clear ambition - driving latency as close to zero as possible.

We’re looking for a Senior Backend Developer who thrives in a deeply hands-on environment and enjoys being close to the code on a daily basis. This role is heavily focused on building, optimising, and scaling backend services in a high-load system where performance and reliability are critical.

You’ll be working on complex, real-time challenges at the core of our platform - improving latency, ensuring high availability, and making systems more efficient at scale. This is not a coordination-heavy role; it’s for someone who enjoys writing production code, solving tough engineering problems, and seeing the direct impact of their work.

If you’re product-driven, take ownership, and prefer a “build first, improve fast” approach while working on systems where every millisecond matters - this role will feel like home.

Key Responsibilities

• Work as part of a cross-functional team owning a core product within the platform

• Design, build, and deliver new backend features end-to-end in a distributed environment

• Write high-quality, production-level code daily, contributing directly to a high-load, scalable system

• Take ownership of services handling financial transactions at scale, with a strong focus on reliability and accuracy

• Proactively suggest and implement improvements in architecture, processes, and development practices

• Participate in code and architectural reviews to maintain high engineering standards

• Solve complex business and technical challenges with pragmatic, efficient solutions

• Participating in on-call rotations within the squad to ensure the reliability and availability of our systems

• Play an active role in ongoing tech transformation initiatives across the platform

• Collaborate closely with engineers, product, and other stakeholders to deliver impactful solutions used by millions globally

Requirements

• Solid experience with Node.js/TypeScript is ideal, but we also welcome experts in other OOP languages such as Java, Python, C++, C#, or Go.

• Strong understanding of asynchronous programming techniques

• Experience with distributed systems and messaging systems (Apache Kafka, gRPC)

• Knowledge of relational databases (MySQL, PostgreSQL), columnar databases (ClickHouse), and NoSQL technologies (DynamoDB, MongoDB)

• Skilled in developing and maintaining end-to-end and unit tests

• Proven track record of developing production-ready solutions

• Degree in Computer Science or related field

Nice to Have

• Experience with large-scale microservices architecture.

• Good ground knowledge of Kubernetes

• Familiarity with cloud providers (especially AWS)

• Understanding of application security and industry best practices

• Understanding of enterprise development patterns

• Active performance observation

• Gambling domain experience
