Sr. Frontend Engineer

About the role

The RoleWe are seeking a Senior Front-End Engineer (AI-First) to join our small but growing engineering team. In this role, you’ll own and shape the user-facing product end to end: designing and building polished, high-performance interfaces, setting front-end technical direction, and leveraging AI-driven tools to accelerate development. You’ll partner closely with Product, Design, and Backend Engineering to turn complex enterprise workflows into intuitive, scalable front-end experiences.

Responsibilities

• Own the front-end architecture for core product surfaces, making thoughtful decisions around state management, data fetching, performance, and scalability.
• Build responsive, accessible, and high-performance UIs using modern front-end technologies (e.g. React, Next.js, TypeScript).
• Design, develop, and evolve a shared component library / design system, ensuring consistency, usability, and maintainability as the product grows.
• Collaborate closely with backend engineers to define API contracts (REST / SSE / GraphQL) and ensure smooth, efficient data flow between frontend and backend.
• Leverage AI-assisted development tools (code generation, refactoring, testing, linting, review) as a core part of your workflow to increase velocity while maintaining high code quality.
• Partner deeply with Product and Design to translate UX concepts and wireframes into production-ready features, proactively identifying edge cases, trade-offs, and implementation risks.
• Drive performance, accessibility, and quality across the front-end stack (load times, responsiveness, cross-browser support, a11y).
• Set and uphold high engineering standards: write clean, testable code; lead by example in code reviews; help define front-end best practices and patterns.

Requirements

Required / Core SkillsSeveral years of professional front-end engineering experience (or equivalent), with deep hands-on experience building production applications using modern JavaScript / TypeScript frameworks (e.g. React, Next.js).Strong mastery of HTML, CSS, and modern styling approaches (CSS-in-JS, design tokens, component-based styling), with a deep understanding of browser behavior, layout, and performance.Proven experience owning and evolving complex front-end systems, not just implementing features.Experience integrating with backend APIs (REST / GraphQL / streaming APIs) and collaborating closely with backend teams on system design.Experience building or supporting realtime, streaming, or AI-driven UI components.Strong product and UX instincts - comfortable working with designers and product managers to refine flows, interactions, and edge cases.High standards for code quality and maintainability; experience with testing strategies, CI/CD workflows, and version control (Git).Strong interest in - and comfort with - AI-augmented engineering workflows, using AI tools to accelerate development without sacrificing correctness or quality.

Qualifications

Nice-to-Have / PreferredExperience building conversational or chat-based interfaces, including managing complex client-side state, streaming responses, and dynamic message flows (e.g. ChatGPT-style UIs).Prior ownership of a design system or shared component library used by multiple engineers or teams.Deep experience with TypeScript in large-scale front-end codebases.Strong background in performance optimization, accessibility (a11y), and cross-browser support at scale.Experience working in a fast-moving startup or AI-native product environment.Strong communication skills - able to clearly articulate UI constraints, technical trade-offs, and architectural decisions to cross-functional partners.
