Senior Software Engineer, Filesystem

WEKA is architecting a new approach to the enterprise data stack built for the age of reasoning. NeuralMesh by WEKA sets the standard for agentic AI data infrastructure with a cloud and AI-native software solution that can be deployed anywhere. It transforms legacy data silos into data pipelines that dramatically increase GPU utilization and make AI model training and inference, machine learning, and other compute-intensive workloads run faster, work more efficiently, and consume less energy.

WEKA is a pre-IPO, growth-stage company on a hyper-growth trajectory. We’ve raised $375M in capital with dozens of world-class venture capital and strategic investors. We help the world’s largest and most innovative enterprises and research organizations, including 12 of the Fortune 50, achieve discoveries, insights, and business outcomes faster and more sustainably. We’re passionate about solving our customers’ most complex data challenges to accelerate intelligent innovation and business value. If you share our passion, we invite you to join us on this exciting journey.

What You’ll Be Doing The filesystem group is a high-powered team responsible for implementing algorithms at scales of 100s of PBs. The team also manages the core filesystem components, including blocks and metadata management, snapshots, RAID logic, object-store tiering, unique cloud disaster recovery features, and more. And most importantly, they skillfully handle the most delicate part of the Weka solution – our customers’ data.

As a Senior Software Engineer, You’ll

• Design and develop distributed file system components to support data management features such as snapshots, replication, tiering, and advanced data reduction algorithms;
• Participate in the design, architecture, and implementation of next-generation storage architecture;
• Assist in technically managing initial storage implementations including proofs-of-concept;
• Diagnose bottlenecks and implement clean and performant solutions to achieve unbeatable performance;
• Design algorithms and data structures to make sure customer data is safe and coherent across our solution in a wide variety of failure modes; and
• Constantly revisit the architecture, algorithms, and methodologies to improve productivity, reliability, and maintainability.

Requirements

• Over 10 years of expertise in low-level, high-performance programming using C, C++, and Rust.
• A thorough understanding of concurrency, inter-process communication, threading models, and synchronization concepts, including significant experience with complex multithreaded software design
• Experience identifying, reproducing, and resolving complex software defects, including root cause isolation, tracing through large source codebases, and implementing long-term fixes as well as short-term workarounds
• 10+ years of hands-on experience with Linux development and debugging, along with a broad knowledge and understanding of Linux internals

It’s Nice If You Have

• Experience in data-path design and development
• Experience with development of highly-distributed systems
• Deep familiarity with concepts and features from the storage industry, including snapshots, replication, transparent data migration, and data reduction techniques
• Experience with ZFS, XFS, or other file systems or with enterprise storage solutions
• Experience working with the Linux filesystem community
• Contribution, upstreaming, or maintaining of filesystem code
• Experience playing a significant role in the implementation of a concurrent, long-running performant server

The WEKA Way

• We are Accountable: We take full ownership, always–even when things don’t go as planned. We lead with integrity, show up with responsibility & ownership, and hold ourselves and each other to the highest standards.
• We are Brave: We question the status quo, push boundaries, and take smart risks when needed. We welcome challenges and embrace debates as opportunities for growth, turning courage into fuel for innovation.
• We are Collaborative: True collaboration isn’t only about working together. It’s about lifting one another up to succeed collectively. We are team-oriented and communicate with empathy and respect. We challenge each other and conduct positive conflict resolution. We are being transparent about our goals and results. And together, we’re unstoppable.
• We are Customer Centric: Our customers are at the heart of everything we do. We ac…
