About The Position

We’re looking for a Senior Software Engineer - Frontend (Geospatial & Computer Vision) to own and evolve ThreeV’s web platform and help define how computer vision and spatial data are translated into intuitive, performant product experiences. This is a hands-on senior IC role for someone who is equally comfortable fixing frontend bugs, building core product features, and implementing advanced visualizations such as computer vision overlays (bounding boxes, segmentation masks, metadata) and layered map-based views. You’ll work directly with our Platform and Machine Learning teams to improve and expand our Inspection Platform while leading frontend development across the broader product suite. This role requires strong frontend fundamentals, comfort working with large image-based datasets, has experience with GIS and the ability to turn model outputs into clear, usable workflows for real customers operating critical infrastructure. As the frontend owner, you’ll be responsible for maintaining product quality and velocity, from day-to-day bug fixes and UX polish to performance optimization and new feature development. You’ll also help define frontend frameworks, tooling, and reusable components as the platform scales. This role is ideal for a product minded software engineer who enjoys frontend problem solving and wants broad ownership at a scaling AI startup with real world impact.

Requirements

7+ years of professional frontend development experience, with senior level ownership of production SaaS applications
Deep expertise with React JS and TypeScript
Strong experience building data dense or visualization heavy web applications
Experience building map-based UIs and rendering layered GIS data in frontend applications
Experience visualizing structured outputs such as bounding boxes, masks, overlays, or similar spatial/imagery-based data
Experience with Canvas, Web Workers, and/or WebGL based rendering
Solid understanding of frontend performance optimization and rendering tradeoffs
Comfortable owning both everyday frontend work (bug fix requests from customers) and larger complex feature initiatives
Strong collaboration skills and experience working closely with Product, Design, and Engineering teams
Ability to work autonomously in a fast-paced startup environment
Excellent written and spoken English, including comfort communicating directly with customers when needed

Nice To Haves

Experience working on AI powered or computer vision enabled SaaS products
Familiarity with geospatial concepts such as tiles, bounding boxes, spatial layers, or imagery pipelines
Experience integrating frontend applications with cloud backed APIs (AWS, Azure, or similar)
Experience contributing to or maintaining design systems (e.g. ShadCN, Tailwind, Storybook)
Hands on experience participating in usability testing or customer feedback sessions
Strong UI sensibility or visual design experience (not required, but a major plus)
Passion for building products with real world impact (climate resilience, social impact)

Responsibilities

Own frontend development across ThreeV’s product suite, including feature delivery, bug fixing, and UX improvements
Translate computer vision outputs (segmentation masks, bounding boxes, confidence scores, JSON metadata) into clear, performant web visualizations
Build and maintain interactive visualization layers for imagery, detections, and asset data, including map-based workflows
Integrate and render layered spatial data using modern mapping frameworks, consuming geospatial APIs provided by backend services
Solve map-style UI challenges such as zoom-level logic, overlay visibility, dynamic label positioning, and viewport-aware rendering
Optimize frontend performance for large datasets, dense overlays, and imagery-heavy workflows using Canvas, Web Workers, and/or WebGL-based techniques
Collaborate daily with backend and ML engineers to connect APIs, model outputs, and data pipelines to the frontend experience
Partner closely with Product and Design to apply human-centered design principles and ensure workflows are intuitive and grounded in customer needs
Participate in customer-facing UAT sessions to validate features, gather feedback, and translate insights into iterative frontend improvements
Define frontend best practices, tooling, and workflows to ensure code quality and scalability as the team grows
Leverage AI-assisted development tools (ChatGPT, Claude, Copilot, Cursor, etc.) to accelerate development, testing, and iteration velocity
