Overview Job Title: Software Engineer — Frontend / Full Stack Location: Bay Area, San Francisco We’re building software at the edge of what’s possible: enterprise SaaS platforms that integrate large-scale scientific data systems with next-generation AI models . Our applications handle terabytes of high-dimensional data and make it usable through elegant, performant interfaces. This is infrastructure for the next decade of discovery in science and machine learning. We’re looking for a full-stack engineer with slope, someone who can own product systems end-to-end, thrives in complexity, and has the technical range to move between LLM architectures, enterprise-scale SaaS, and modern front-end design . Responsibilities Building and scaling core SaaS infrastructure that supports data-heavy scientific and AI workflows. Designing and implementing novel LLM-powered systems and deploying them into real products. Architecting web applications that can process and visualize massive, multidimensional datasets with speed and clarity. Owning customer workflows: onboarding, workspace creation, deployment, and lifecycle management for enterprise-scale clients .

Shaping the design system, UX, and product feel so that the most complex data and AI tools become intuitive to use. What You Bring 4+ years building enterprise SaaS applications at scale . Strong background in full-stack development (60% frontend). Deep programming ability and experience designing novel architectures for LLMs (scalable serving, RAG, fine-tuning pipelines). Experience working with large datasets and surfacing them in high-performance, intuitive interfaces. A portfolio of production systems used by enterprise customers . The ability to simplify complexity without dumbing it down. Sharp technical taste in system design, architecture, and product UX . Comfort collaborating with domain experts in ML, biology, chemistry, and other scientific fields. Why This Role Matters You’ll be designing the foundations of products that change how scientists and researchers work with data and AI. You’ll build systems that don’t just scale, they unlock entirely new workflows. And you’ll do it alongside a team of people who care deeply about building software that lasts. #J-18808-Ljbffr
