Responsibilities
- Design, build, and operate JVM-based microservices using Java and Kotlin.
- Own services end-to-end including architecture, implementation, deployment, monitoring, and on-call participation.
- Apply concurrency and performance practices such as asynchronous programming, backpressure, and memory management.
- Build and evolve event-driven systems using Kafka for streaming and schema evolution.
- Instrument services for observability and define SLIs/SLOs to drive reliability.
- Automate CI/CD, testing, and operational tasks to improve developer productivity.
- Collaborate with product, architecture, and cross-functional partners.
- Mentor peers, review designs and code, and contribute to technical standards.
Requirements

- Solid understanding of distributed systems concepts and microservice design.
- Hands-on experience with asynchronous and reactive programming.
- Proficiency with REST/gRPC API design and resilience patterns.
- Practical experience with containers, Kubernetes, and CI/CD pipelines.
- Track record of operating services in production including incident response and postmortems.
- Strong communication skills and ability to write design documentation.
Preferred qualifications
- Deep JVM performance profiling and tuning experience (JFR, async-profiler, JMH).
- Experience with schema registries and serialization formats (Avro, Protobuf).
- Experience with stream processing (Kafka Streams, Flink).
- Familiarity with data stores used in observability stacks (Cassandra, Elasticsearch, Redis).
- Experience with OpenTelemetry.
- Prior technical mentorship or leadership in reliability and performance initiatives.
- Experience with Kafka or similar streaming technologies.
Workplace
