Senior Frontend Engineer

About Aragorn AI

Aragorn AI is reimagining how People Ops teams operate in the age of AI. We’re building a platform that unifies HR data and transforms how organizations make decisions, unlock insights, and run operations. Our mission is simple but ambitious: help HR teams move faster, smarter, and with more confidence.

We’re on a mission to reach $10M ARR and you will be at the heart of that journey — building the AI-powered systems that will redefine how companies manage their people. This is a senior, hands-on engineering role — you will own major pieces of our frontend architecture, push the boundaries of design system implementation, and ensure a world-class user experience for our customers

What You’ll Own

You will architect, build, and optimize the frontend that powers Aragorn’s Analytics & Agentic HR Studio platform. You will:

• Lead development in React, TypeScript, and Webpack, ensuring performance, maintainability, and scalability

• Implement and evolve our micro frontend architecture to support modular, scalable product delivery

• Collaborate directly with the Product Designer and Head of Product to translate UX designs into high-quality, performant code

• Work with our design system, ensuring components are reusable, accessible, and optimized for developer experience

• Critique and collaborate on UX/UI designs, proactively identifying implementation constraints and optimization opportunities.

• Work closely with backend engineers to define, consume, and optimize APIs for efficient data communication.

• Make strategic decisions on when to leverage third-party libraries versus custom implementations to balance speed of delivery with long-term maintainability

• Own CI/CD pipelines for frontend applications — configuration, optimization, and deployment.

• Champion frontend performance best practices, from bundle size reduction to runtime optimization.

• Contribute to setting technical standards and architecture consistency for the frontend team

• Participate in architecture and roadmap discussions to ensure scalability and long-term flexibility of the platform.

You Might Be a Fit If You

• Have 5+ years of professional experience building modern React applications at scale

• Have deep expertise in TypeScript, Webpack, and modern frontend tooling

• Have implemented micro frontend architecture in production environments

• Have built and scaled component-based design systems in collaboration with design teams

• Can translate Figma designs into pixel-perfect, performant implementations — and know when and how to challenge a design for feasibility

• Have a strong sense of UX and can identify ways to simplify complex workflows

• Understand REST and GraphQL API structures, and how to design frontend code that integrates cleanly with backend services

• Have experience configuring and deploying applications in CI/CD environments

• Write clean, maintainable, and well-tested code that other developers can easily build on.

• Are fluent in frontend performance optimization strategies — from bundle splitting to virtualization.

• Thrive in collaborative environments where designers, engineers, and product work as one team.

• Enjoy balancing speed of delivery with architectural and code quality

Why This Role Is Special

• Product-defining impact: you will shape the UI/UX of the core Analytics and Agentic Studio platform used by enterprise HR teams

• Close collaboration with founders and product design: fast feedback loops and zero corporate bureaucracy

• Cutting-edge architecture: micro frontends, dynamic design systems, real-time analytics, and agentic AI

• Product ownership: equity, technical decision-making power, and the ability to leave your mark on a category-defining product

What Success Looks Like in the First 6 Months

• Production-ready micro frontend architecture supporting multiple product modules

• Fully integrated and documented design system adopted across all frontend codebases

• Highly performant React applications that load fast and run smoothly

• Clear documentation of frontend architecture, component usage, and deployment workflows.

• Seamless collaboration with Product Design and Backend teams, reducing handoff friction and speeding up delivery cycles
