Senior Backend Engineer (Core Team)

About this role

About the Role

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

What We Offer

- Competitive Salary

- Quarterly Bonuses

- Unlimited Paid Time Off

- Unlimited Paid Sick Leave

- Remote & Flexible Working

- Private Medical Insurance

- Financial Support for Life Events

- Professional Development Budget

- International Exposure

- Regular Company Events

*Benefits may vary depending on location and contractual agreement
