Job description

Ategrity Specialty Insurance Company is a leading provider of property, casualty, management liability, and professional liability insurance, specializing in the excess and surplus (E&S) lines market.

Overview

We're looking for a product-minded Front-End Developer. This role will own and support the user-facing experience while collaborating closely on front end architecture

Role:

• Own and build modern, responsive, high-performance frontend experiences
• Develop UI components with reusability and scalability in mind
• Collaborate on API design and integration with backend systems
• Improve UX through thoughtful interaction design and performance optimization
• Work closely with backend engineers to define clear contracts and boundaries
• Contribute to product discussions beyond implementation

Responsibilities:

Stack and Framework

• Strong React, Vue, or Angular experience
• TypeScript proficiency as a hard requirement, not optional
• Experience building SPAs that consume REST APIs from a separate backend
• Familiarity with modern build tooling (Vite preferred, Webpack or Rollup acceptable)
• Comfortable making framework and tooling decisions, not just executing someone else's
• Knows when NOT to reach for heavy abstractions (no Redux on day one for a 10-screen app)

Migration and Greenfield Work

• Experience converting or rebuilding a frontend from one stack to another
• Experience standing up a new frontend codebase: build pipeline, linting, formatting, testing, component library foundations
• Has opinions on state management, routing, and data fetching patterns, and can defend them
• Comfortable working from an unfinished spec where requirements are still landing

Complex Form and Data UI

• Multi-step wizard and stepper UI experience
• Dynamic form generation from schema or config
• Client-side validation paired with server-side validation
• File upload UX (progress, retry, validation, multi-file)
• Complex data tables with filtering, sorting, pagination, bulk actions

API and Auth Collaboration

• Strong experience with auth token flows, refresh, and error handling in a SPA
• Familiarity with TanStack Query, SWR, or similar data-fetching libraries
• Experience implementing OAuth or SSO flows on the client side (Azure Entra ID context)
• Thinks about loading, error, empty, and unauthorized states by default
• Familiarity with Bruno, Postman, or similar API clients

Permissions-Aware UI

• Experience with role and permission-driven UI (hide, disable, redirect patterns)
• Understands that UI gating is UX, not security

Tooling and Quality

• Git proficiency: branching strategy, pull requests, code review participation
• At least basic frontend testing discipline
• Documentation habits

AI-Assisted Development

• Regularly uses AI tools (ChatGPT, Copilot, Cursor, etc.) to improve development speed and quality
• Comfortable leveraging AI for debugging, scaffolding, refactoring, documentation, and research
• Knows how to validate and refine AI-generated code rather than blindly accepting output
• Interested in incorporating AI into everyday engineering workflows and productivity

Domain and Soft Fit

• Insurance, fintech, or other regulated-industry experience, or genuine interest in learning the domain
• Comfortable in a very small team
• Willing to push back on design or product decisions with reasoning
• Self-directed and able to operate with minimal handholding
• Comfortable with shifting requirements in an early-stage product

How You Work

• You prefer ownership over handholding
• You care about clean separation of concerns
• You're comfortable operating without heavy management overhead
• You think in UX goals, not just tickets
• You'd rather build great product than sit in meetings

What Success Looks Like

• A fast, intuitive, and polished frontend experience
• Shipping features that measurably improve user experience
• All UX components build on related components
• Clear boundaries between frontend and backend systems
• Competitive salary + performance incentives
• Flexible work environment
• Work in a dynamic, low-friction environment with innovative, world-class engineering, operations and product colleagues
• Opportunity to shape product architecture and direction
