• Build intuitive and elegant user experiences to empower fellow KoBolders with backgrounds in geology, geophysics, geochemistry, and data science. • Own and improve KoBold’s existing web apps that manage data upload, discovery, search, and visualization. • Collaborate with scientists to architect new tools to support complex, interactive 2D/3D geospatial visualizations, plotting, and data labeling. • Champion frontend best practices. Modernize our stack to standardize our UIs, prototype faster, and deploy useful apps for our geologists and data scientists. Mentor junior developers. • Setup systems to automate the testing of our UIs.

• Develop limit-management interfaces using Angular 15+ and TypeScript, ensuring usability, modularity and performance. • Integrate RESTful APIs to consume and update data in transactional platforms, ensuring security and compliance. • Create volume/metrics dashboards using a reusable component architecture to enable efficient data visualization. • Automate execution and coverage of unit tests (Jest) and E2E tests (Cypress), including critical flows and edge-case scenarios. • Collaborate on configuring CI/CD pipelines, automated deployments and Git versioning. • Optimize frontend delivery through AWS infrastructure (S3, CloudFront, Lambda, API Gateway), applying best practices for caching and performance. • Participate in initiatives involving Autonomous AI (Spec Driven Development, agents), contributing to the product's technological evolution.

• Develop, design, debug, and modify components of software applications and tools in agile environment • Write automated unit and integration tests as appropriate to support our continuous integration pipelines • Participate in code reviews to assess overall code quality and flexibility • Have a good understanding of Software Development Lifecycle and methodologies, specifically scrum and/or Kanban • Prototype creative solutions quickly by developing minimum viable products and work with seniors and peers in crafting and implementing the technical vision • Communicate and work effectively with distributed cross functional teams • Resolve problems and roadblocks as they occur with peers - follow through on details and drive issues to closure • Work towards continuous improvement in software and development process within an agile development team • Participate in user story creation in collaboration with the team

• Build and maintain production-grade Next.js (App Router) + React + TypeScript applications — dashboards, chat/copilot surfaces, and agentic research UIs. • Design and ship data visualizations (time series, breakdowns, combo charts, KPI strips) with a charting library (we use ECharts) — readable, performant, on-brand. • Craft AI/agent UX: streaming "thinking" traces, multi-step/agent fan-out progress, grounded follow-up conversations, and the rich result artifacts (boards, reports, canvases) users interrogate. • Own and extend a design system — design tokens, reusable components, motion/animation, and accessibility — keeping a large surface visually consistent. • Prototype mock-first for rapid product iteration, then graduate proven flows to real data and APIs. • Care about performance and correctness: React rendering, SSR/hydration, bundle size, and the subtle bugs that come with modern React. • Do light fullstack glue: build and consume REST/JSON APIs, wire up a backend service or BFF endpoint, shape data contracts, and integrate LLM/agent backends. • Keep the codebase healthy: typed, linted, documented, and easy for the next person (human or AI agent) to pick up.
