As a Senior Software Engineer, you'll work on high-impact systems problems such as:

• Optimizing metadata management, caching, and replication across thousands of nodes.
• Designing concurrent, fault-tolerant services for multi-region and multi-cloud environments.
• Evolving Alluxio's storage abstraction and scheduling layer to support large-scale AI/ML data pipelines.
• Collaborating with internal product teams to push the limits of distributed I/O performance.

This is a hands-on, architecture-plus-implementation role for engineers who love deep systems work and want visible impact in a small, senior, highly technical team.

What You'll Own

• Cache and metadata enhancements - design and implement improvements to caching policies, eviction logic, and metadata scalability to increase performance and reliability.
• Data path optimization - refine I/O pipelines for S3/GCS/HDFS/Posix to reduce latency and improve throughput using concurrency and scheduling techniques.
• Distributed systems reliability - strengthen consistency, replication, and fault-tolerance mechanisms across large-scale clusters.
• Feature development and integration - collaborate with product and solution-engineering teams to deliver features that support AI and analytics workloads.
• Code quality and peer collaboration - participate in design reviews, provide constructive feedback, and ensure robust testing and observability in production systems.

What We're Looking For

• Strong computer-science fundamentals and a passion for large-scale distributed systems.
• Professional experience developing in Java, C++, or Go.
• Practical knowledge of concurrency, replication, distributed coordination, and performance tuning.
• Experience with distributed storage, caching, or data-access layers (e.g., Spark, Presto, Hadoop, Kubernetes).
• Bachelor's or advanced degree in Computer Science or related technical field (or equivalent experience).

Why Alluxio?

• Build infrastructure trusted by the world's largest AI and data-driven companies.
• Join a small, senior engineering team where your designs shape the product's evolution.
• Work directly with the original creators of open-source Alluxio.
• A culture of empathy, curiosity, and ownership - where engineers collaborate closely to solve hard problems.
