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.

As a Senior Software Engineer, you’ll:

You will be responsible for building the "brain" of Weka’s main product, which is a distributed file system —the layer that manages orchestration, metadata, cluster membership, and implements complex logic required to manage hundreds of thousands of nodes, for cluster scaling, automated failover, zero-downtime rolling upgrades and "self-healing" to detect and remediate hardware failures or network partitions.

• Design, implement, unit test, and maintain services that coordinate and the cluster 
• Optimize Performance: Work with complex data structures like spanning trees  or LSM-Trees, concurrency control mechanisms (MVCC) to improve speed and efficiency.
• Collaborate closely with cross-functional teams to translate backend capabilities into real-world impact

Requirements:

• Ownership mindset, self-direction, and a passion for solving complex problems.
• 5 year experience in systems programming, preferably C/C++
• Proven experience building complex, high-performance distributed systems such as databases, file systems, or distributed data platforms, at scale
• Strong distributed troubleshooting and incident resolution skills.

It's nice if you have:

• Experience with Rust/ Go
• Experience with NGINX/Envoy and general background in networking concepts 
• Experience working with K8s 
• Experience with distributed consensus protocols (such as  Raft or Paxos)

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 actively listen and prioritize the success of our customers, and every decision we make is driven by how we can better serve, support, and empower them to succeed. When our customers win, we win.
