Job description

Overview

Our client is looking for a Senior Front-End Engineer to take ownership of their web platform and help define the next generation of user experience across the entire product catalog. This is a lead role for a self-starter who thrives in a startup environment, enjoys building beautifully engineered products, and knows how to translate AI and computer vision outputs into compelling visual experiences.

In this role, you’ll work directly with the Head of Product, the Design team, and Engineering teams to improve and expand the existing Inspection Platform, while leading front-end development for upcoming features across the broader product suite. You’ll collaborate closely with backend and ML engineers, bring your own ideas to the table, and be expected to leverage modern AI coding tools (ChatGPT, Claude, Copilot, etc.) to accelerate development, productivity, and testing.

You’ll also play a key role in shaping the user experience and human-centered design efforts as the platform evolves. This includes working closely with customers to gather feedback, validate workflows, and continuously improve usability across the product. Strong experience collaborating deeply with designers is essential.

As the front-end owner across the company, you’ll be responsible for defining and maintaining front-end frameworks, tooling, and workflows, establishing best practices, and organizing a reusable, well-documented component library. Your work will enable other front-end engineers to efficiently leverage existing patterns and components as the team grows. This is an ideal role for someone who wants to be the go-to front-end leader at a growing AI startup.

Responsibilities

• Own the front-end development and evolution of our client’s product suite
• Lead front-end UI development and ensure consistency across multiple products
• Translate AI and computer vision outputs (segmentation masks, bounding boxes, JSON metadata) into rich, high-performance web visualizations
• Build, maintain, and document a component library using ShadCN, Radix UI, Tailwind, and Storybook in collaboration with visual designers
• Collaborate daily with backend engineers and designers to ensure usability, scalability, and design consistency
• Work closely with backend and ML teams to integrate APIs, model outputs, and data pipelines into the front-end experience
• Bring creative ideas to improve UX and developer experience, from prototyping new views to optimizing rendering performance
• Leverage AI-assisted workflows (ChatGPT, Claude Code, Copilot, etc.) to increase velocity, improve test coverage, and enhance code quality
• Participate in roadmap planning, scoping sessions, and internal reviews as the front-end lead
• Partner closely with the Design team to apply human-centered design principles and ensure workflows are intuitive and grounded in real customer needs
• Participate in and help run customer-facing UAT sessions alongside design and product teams
• Translate customer feedback and usability findings into concrete front-end improvements and iterative design enhancements
• Support visual design execution when appropriate, ensuring high-quality UI implementation aligned with product and brand standards

Minimum Qualifications

• 7+ years of front-end development experience; 2+ years in a senior or lead role preferred
• Deep expertise in React (Next.js) and TypeScript
• Proven ability to integrate and visualize AI/ML outputs (JSON metadata, segmentation, bounding boxes, etc.) in scalable web interfaces
• Experience solving Google Maps–style visualization challenges, including zoom logic and dynamic repositioning of text, icons, and overlays
• Strong experience with Tailwind, Radix UI, ShadCN, and Storybook
• Excellent collaboration skills and comfort working directly with product and design teams
• Ability to work autonomously in a fast-paced startup environment
• Strong understanding of human-centered design principles
• Excellent written and spoken English, with the ability to communicate clearly with cross-functional teams and customers

Preferred Qualifications

• Experience with GIS platforms such as ArcGIS (ESRI)
• Background in computer vision or AI-powered SaaS products
• Familiarity with cloud environments (AWS, Azure) and backend API integration
• Active use of AI development tools (ChatGPT, Claude, Copilot, Cursor, etc.)
• Experience defining or contributing to design systems
• Passion for building products with real-world impact (climate resilience, infrastructure safety, etc.)
• Hands-on experience with UX research, usability testing, or customer research
• Visual design experience or strong UI sensibility (not required, but a big plus)

Education

• Bachelor’s degree in Computer Science, Software Engineering, or a related field required
• A Master’s degree is preferred but not required; equivalent practical experience and a strong portfolio of shipped products are equally valued

Our client is a remote-first company, with a primary base in Los Angeles, CA. They support flexible remote work, allowing team members to work from wherever they are most productive. At the same time, they value in-person connection and host multiple all-hands offsite meetings each year to foster collaboration and team cohesion. The environment balances remote flexibility with in-person moments that matter, supporting a connected and high-performing global team.
