About the Role
We’re looking for a Senior Software Engineer to join Kambi. This is not a standard backend role.
You will work on business-critical systems where:
- Performance matters.
- Reliability is essential.
- Correctness is critical.
We’re looking for someone who takes ownership, makes sound technical decisions, and contributes effectively in a complex, high-impact environment.
What You’ll Do
- Design, build, and maintain high-throughput backend services in Java
- Work with low-latency, distributed systems
- Solve real production challenges related to performance, failures, and scaling
- Take ownership of systems and features end-to-end
- Collaborate closely with engineers, product, and stakeholders
- Contribute to architectural decisions and technical direction
- Continuously improve system reliability, observability, and maintainability
What You Bring
- Strong Java & Backend Expertise
- Solid understanding of: Concurrency and multithreading
- JVM behavior (memory, garbage collection, performance)
- Core Java fundamentals
- Experience building backend services using frameworks such as Spring Boot
Experience Working with Production Systems
- Hands-on experience debugging and resolving issues in live systems
- Familiarity with observability practices (logging, metrics, tracing)
- Experience identifying and addressing performance bottlenecks
- Understanding how systems behave under real-world load
Distributed Systems & System Design
- Experience working with microservices and/or event-driven architectures
- Understanding of: Scalability and fault tolerance
- Backpressure and system resilience
- Trade-offs such as consistency vs availability
- Experience with messaging systems (e.g. Kafka) is highly valued
Ownership & Engineering Judgment
- Take responsibility beyond individual tasks and drive work forward
- Operate effectively in environments with some ambiguity
- Proactively identify issues and drive improvements
- Make sound technical decisions and clearly communicate trade-offs
- Balance simplicity, performance, and long-term maintainability
- Understand the operational and maintenance impact of technical choices
This Role May Not Be the Right Fit If
- Your experience is primarily limited to simple CRUD-based applications
- You have limited exposure to debugging or operating production systems
- You are most comfortable working in environments where requirements are fully defined upfront and change is limited
- You are not comfortable taking ownership of systems end-to-end
Tech Context
- Java (primary)
- Spring Boot
- Distributed systems and messaging (e.g. Kafka)
- Cloud-based infrastructure
- Containerized environments
Application
Please share your CV in English. Along with your CV, to help us better understand your experience, kindly include a brief description of a complex production issue you personally debugged, how you approached it, and the outcome.
