Join us as a Principal Member of Technical Staff on our Lightning team in Israel to do the best work of your career and make a profound social impact. As a core member of our elite innovation unit, you will architect and build next-generation AI/HPC storage platforms enabling massive-scale "AI Factories."

You will operate as a deep technical leader, influencing architecture and solving complex system-level challenges across distributed filesystems and performance engineering.

As a member of Technical Staff, you will be responsible for designing and building next-generation distributed storage systems for AI and HPC workloads, focusing on extreme performance and scalability. You will work with product architects and global engineering teams on advanced filesystems, data services, and performance-critical platform innovations.

You will:

Architect extreme-scale distributed storage systems tailored for AI model training and large-scale GPU clusters.

Design and develop high-performance, multi-threaded components in C/C++ on Linux/Unix platforms.

Lead the evolution of parallel filesystems (Lustre, GPFS) and scale-out NAS architectures.

Drive end-to-end performance analysis and optimization, identifying and eliminating bottlenecks in I/O paths and memory usage.

Partner with product architects and senior leadership to translate complex customer requirements into scalable, resilient technical solutions.

This is a high-ownership, builder-first Sr. Software Engineer role. You will design, build, and ship AI-integrated data systems from concept through production - owning outcomes end-to-end, including deployment, monitoring, cost, and business impact.

We are seeking a candidate who views AI tooling as a fundamental force multiplier in their daily engineering process. This position is central to our transition into an AI-native function, requiring an individual capable of making decisive, pragmatic architectural choices on reversible matters to maintain momentum. We need an experienced builder of production-grade, data-centric systems who is obsessed with delivering customer value and possesses a deep, curious enthusiasm for the transformative potential of AI.

What You Will Build
AI-Native Systems Development. Design, build, and own scalable data and ML pipelines, backend services, and AI-powered capabilities that are part of the platform's production decision-making layer. AI and ML components are runtime dependencies in this role - not research projects or experiments. Candidates will have strong back end and data engineering skills to thrive in this space.
Daily Shipping. Decompose complex work into safely mergeable increments and ship them daily. Treat large, multi-day pull requests as a risk to momentum. Use feature flags, canary releases, and rollback architecture to manage risk through isolation - not through avoidance.
AI-Augmented Engineering Workflow. Leverage AI-assisted development tooling (code generation, automated testing, architecture prototyping) as a core workflow multiplier. Evaluate and experiment with emerging AI tools and frameworks with direct hands-on engagement. Bring technical depth to AI fluency - architecture and capability tradeoffs, not surface-level awareness.
End-to-End Ownership. Own your work from design through production deployment, operational monitoring, and business impact measurement. Accountability extends beyond the feature to CI/CD pipeline health, observability, cost efficiency, and domain-level outcomes.
Architectural Decision-Making. Make pragmatic, timely architectural choices that balance modern AI and data technologies with reliability, cost, and delivery speed. Distinguish reversible vs. irreversible decisions and move forward without waiting for consensus on the former. Document decisions in lightweight ADRs and own the outcomes.
Cross-Functional Collaboration. Partner with product, design, infrastructure, and GTM teams to translate customer and business needs into technical solutions. Operate with business awareness - understand how your systems impact revenue, customer outcomes, and strategic priorities.
