We are seeking a driven Java engineer to join our global research platform team in Mumbai. The team builds and operates the compute and data platform that powers all of IMC's quantitative research: a large-scale Kubernetes-based research cluster, a distributed job scheduling platform used by every trading and research team, and the market-data and dataset services that feed research on it. Mumbai runs one of the platform's regional production deployments, and you'll collaborate closely with platform colleagues in Amsterdam, Chicago and Sydney.
Your Core Responsibilities:
- Design, build and operate the Java backend of our distributed job scheduling platform: the job controller and state machine, scheduling integrations, resource and cost tracking, and the failure-recovery machinery that keeps research workloads running at scale
- Develop gRPC/protobuf APIs consumed by Python, Java and C++ clients across the firm
- Build event-driven services on Kafka for job lifecycle tracking, data lineage, and dataset orchestration
- Work hands-on with Kubernetes at scale: pod scheduling, fair-share queueing, preemption and multi-cluster placement
- Instrument, monitor and firefight production systems, and drive root-cause analysis of performance bottlenecks
- Support and consult research users in the India office
Your Skills and Experience:
- 3+ years of professional Java development experience (Java 17+, Maven/Gradle, strong grasp of concurrency and JVM performance)
- 2+ years of hands-on experience with Kubernetes and Docker (building on the Kubernetes API is a strong plus)
- Comfortable developing in Python; our client libraries and research users are Python-first, and you'll work on both sides of the API
- Solid understanding of distributed systems fundamentals: state machines, retries/idempotency, event-driven architectures, and consistency trade-offs
- Experience with workload scheduling or batch/compute orchestration systems, such as Kubernetes schedulers, Slurm, YARN, Kueue, Ray, or Airflow
- Experience with messaging and streaming systems such as Kafka
- Working knowledge of NoSQL and time-series/SQL databases, such as MongoDB and PostgreSQL
- Experience with gRPC/protobuf or similar RPC frameworks is a plus
- Strong Linux fundamentals and scripting skills in bash and Python
- Experience with monitoring stacks, including Prometheus, Grafana, and alerting, and comfort operating what you build
- Demonstrated ability to troubleshoot across the stack, from application code through Kubernetes to network and storage
- Exposure to object storage such as S3 or high-performance data formats such as Parquet and Iceberg
