Software Development Engineer, Multi Region Journal

Ever wonder how AWS services achieve strong consistency across multiple regions how a write in one region becomes instantly visible in another with full transactional guarantees Behind the scenes Multi-Region Journal is making it all possible and youd be helping build it.

Multi-Region Journal (MRJ) is a reliable resilient transactional multi-region replication used to build strongly consistent (serializable sequentially consistent) solutions in domains like storage messaging and streaming. It is the AWSs standard cross-region primitive used by AWS applications to build multi-region capabilities.

The MRJ team is actively expanding the services footprint to meet growing customer demand hardening multi-region consistency guarantees under failure scenarios and partnering with multiple flagship AWS services to onboard them onto MRJ as their cross-region backbone.

As an SDE on the Multi-Region Journal team youll design and build the next generation of cross-region infrastructure that AWSs biggest services depend on. Youll work on novel distributed systems challenges that go beyond single-region think quorum protocols across continents consistency under network partitions and sub-second failover across regions.

Key job responsibilities
1. Design develop and test features for a highly available low-latency multi-region replication system that provides strong transactional guarantees.
2. Architect solutions for novel challenges in cross-region consensus fault tolerance and consistency.
3. Code and test in high-performance programming languages including Java and Rust.
4. Deliver software projects end-to-end: requirements gathering design implementation deployment and operations.
5. Participate in design reviews code reviews and operational excellence initiatives.
6. Mentor other engineers and contribute to a collaborative team culture.

A day in the life
Multi-Region Journal engineers tackle problems that sit at the intersection of distributed systems theory and large-scale production engineering. Youll reason about consistency models across geographic boundaries design protocols that tolerate region-level failures and implement systems that must be both correct and fast.

This is a hands-on position with end-to-end ownership: youll go from whiteboard designs to production deployments serving AWSs largest customers. Youll work alongside experienced engineers who are invested in solving hard problems together.
