Job summary

Percona’s MongoDB Tools Team is hiring for a remote role focused on PCSM and PBM projects. You will influence the shape of PCSM, work across PBM, and tackle hard problems in replication, change streams, and cross-cluster consistency.

You will own core replication, fault tolerance at scale, and shard-aware syncing, while contributing to an open source ecosystem with широк collaboration and community involvement.

Qualifications

• Strong Go experience in production, with real fluency in concurrency.
• Solid grounding in distributed systems and data consistency.
• Hands-on MongoDB knowledge: change streams, the oplog, resume tokens, replica sets, and sharding.
• Comfort building and operating command-line tools and HTTP APIs, and instrumenting them with metrics and structured logs.
• A habit of writing tests that catch real problems, and comfort working across a mixed toolchain.
• Experience working in the open: Git and pull request workflows, giving and taking code review well.

Responsibilities

• The core replication engine: initial collection cloning followed by continuous change capture over MongoDB Change Streams, with correct handling of resume tokens, ordering, and resumability after failures.
• Correctness and fault tolerance at scale: recovering cleanly from network drops, primary elections, and restarts without losing or duplicating changes.
• Sharded cluster support: replicating across shards, handling chunk migrations and balancer activity.
• Namespace filtering and automatic index management, plus edge cases with DDL, TTL, and index differences.
• Performance and throughput: parallelizing the clone, applying backpressure, and managing memory and connections.
• The CLI and HTTP API that drive and observe a sync, and the metrics/logging for operators.
• Shared across both projects: working in the open, PRs, reviews, and community involvement.
