About Terra AI We are building the state-of-the-art AI platform for the discovery and development of clean energy and mineral resources. We bring the most advanced techniques in generative AI, foundation modeling, and autonomous decision optimization to tackle the most important problems in the geosciences. These systems can help more reliably identify critical resource deposits, more rapidly measure and characterize them, and design more efficient and sustainable production plans. We are backed by Khosla Ventures and other leading venture investors. We are now looking to grow our team from ~15 to ~30 by the end of the year to continue to mature our technology and support deployment with our world-class mineral and clean energy partners. Role Build and own Terra AI’s customer-facing web application. You will turn core platform capabilities into a product users can trust, with high standards for reliability, UX, and iteration speed. This is a staff-level role because you will set the technical direction for a greenfield app and get the team off on the right foot. What you’ll do Own the web app end to end: architecture, implementation, quality, performance, and ongoing operations. Lead incremental feature delivery for a greenfield product, including shaping milestones and sequencing work into shippable slices. Build core UI flows for interacting with exploration outputs, including data-heavy views and 3D visualization of geological datasets. Design clean interfaces to backend services: APIs, auth, permissions, data contracts, error handling, and versioning. Design resilient, fault-tolerant systems across frontend and backend, with clear operational ownership. Establish software development standards for the web app: code quality, testing strategy, reviews, release discipline, and documentation. Design and evolve data storage patterns (relational or NoSQL), including schema design, migrations, and integrity constraints where appropriate. Implement unit, integration, and end-to-end tests for critical paths. Configure monitoring and alerting to catch downtime and performance degradation early. Meet with stakeholders and end users to inform requirements, validate usability, and drive adoption. Requirements Proven ownership of a production web application, including operating it in the real world. Strong Python ability, enough to build and maintain backend services and make principled technical decisions in a Python-first environment. Strong frontend fundamentals (component design, state management, performance, accessibility). React is a plus, not a requirement. Ability to set architecture and standards in ambiguous environments, and to execute without needing heavy process. Experience designing and maintaining evolving database schemas. Comfort with cloud and modern deployment environments (Kubernetes experience is a plus). Nice to have Experience building data-intensive applications with meaningful 3D visualization (not low-level graphics programming). Familiarity with libraries used for 3D visualization in web apps (Three.js, VTK.js, or similar). Experience with AWS primitives commonly used for production systems (compute, storage, managed databases, container orchestration). Experience in scientific, engineering, or industrial software where correctness and trust matter. Prior experience leading a product area or small team, formally or informally.
