Company Overview

Three

V Technologies, Inc. is an early-stage venture backed startup. We’re developing a Multi-Sensory Asset Intelligence Platform (MSAIP) to revolutionize asset heavy industries like Power & Utilities, Renewables, and Public Infrastructure. Our goal is to become the B2B Perplexity AI for the physical world. The Three

V platform uses frontier AI techniques like customized Large Language Models, as well as applying the latest computer vision model architectures to drastically improve the end-to-end inspection process. This allows customers to cut operations & maintenance costs, streamline inspection decisions, and improve data accuracy to prevent asset failures. Global high profile safety incidents like wildfires over recent years underscore the urgent need for our platform, making it not just innovative but essential.

Job Summary

We’re looking for a Senior Software Engineer - Frontend (Geospatial & Computer Vision) to own and evolve Three

V’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.

Key Responsibilities

• Own frontend development across Three
  
  V’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

Minimum Qualifications

• 7+ years of professional frontend development experience, with senior level ownership of production SaaS applications
• Deep expertise with React JS and Type Script
• Strong experience building data‑dense or visualization heavy web applications
