Distributed Storage Engineer (Apache Ozone Internals) – Remote

About the role

BairesDev is looking for a senior Distributed Storage Engineer to work on the core of Apache Ozone. You will dive deep into the storage engine, handling replication, consistency, metadata management and coordination across Object Manager, Storage Container Manager and DataNodes at petabyte scale.

Key responsibilities

• Contribute production‑grade code to the Apache Ozone project.
• Debug and optimise Ozone internals – replication, consistency, metadata management, OM/SCM/DataNode coordination – at petabyte scale.
• Resolve complex distributed issues such as replication failures, networking, disk I/O and concurrency problems.
• Improve performance and scalability of distributed storage operations.
• Collaborate with cross‑functional engineering teams and open‑source committers on integrations and ecosystem work.
• Mentor senior engineers and raise the engineering bar through code reviews and design critiques.

Required profile

• 6+ years of software development experience.
• Strong Java expertise.
• Solid background in distributed systems and concurrent or parallel programming.
• Working knowledge of replication, consistency, fault tolerance and metadata management in storage systems.
• Hands‑on experience with at least one distributed storage system (Ozone, HDFS, Ceph, MinIO, or equivalent) beyond consumer‑level usage.
• Familiarity with JVM performance characteristics (GC, memory, threading).
• Advanced level of English.

Required skills

• Java
• Apache Ozone
• Hadoop ecosystem (HDFS, Iceberg, Hive, Parquet, ORC)
• Distributed storage concepts (replication, consistency, fault tolerance, metadata management)
• Concurrency and parallel programming
• JVM performance tuning (GC, memory, threading)
• Kubernetes (nice to have)
• Cloud‑native storage deployment (nice to have)
