About the role

Key responsibilities & impact

Take Ownership: You’ll be accountable for upholding a high bar for quality through design reviews, code reviews, test strategy, and production readiness.
Collaborate cross-functionally: Partner with product, design, and fellow engineers to shape solutions, clarify tradeoffs, and deliver reliably.
Architect for change: Design and build full-stack, frontend-leaning systems that are intentionally small, composable, and resilient to evolving product requirements.
Improve Performance & Quality: Enforce architectural and operational quality, catching subtle issues that are easy to miss in fast-moving, AI-assisted development.
Champion Functional Patterns: Champion functional programming principles and immutability to reduce side effects and make systems simpler to reason through and debug.
Lead AI-assisted development: You’ll use AI assistants/agents for prototyping, scaffolding, refactoring, and exploratory development, then harden the result and rigorously validate through tests, reasoning, and edge-case review.
Raise quality through testing: Build and maintain a strong automated test suite of unit, integration/contract, component/UI, and end-to-end coverage, with fast feedback loops in CI.

Requirements

What you’ll need

Bachelor’s degree in Computer Science, Engineering, or a related field
8+ years of experience building production web applications and 1+ years as a principal engineer
Expert-level proficiency with TypeScript, strong experience with React, server-side rendered Next.js (or similar), and performant component-driven development (e.g. Reshaped UI)
Ability to articulate complex technical trade-offs to stakeholders and translate product vision into high-fidelity technical direction
Demonstrated development of simple, reusable, changeable systems (with examples of refactors, platforming work, or scalable patterns)
Preference for functional programming and a deep understanding of why immutability is critical in modern frontend development
Advanced knowledge of the testing pyramid and how to use automated tests as a safety net for rapid, iterative development
Proven technical leadership through mentorship, delegation, and high-quality code reviews
Hands-on experience with tools like Cursor (or equivalent AI-augmented IDEs) and all modern coding models
Practical understanding of where AI is strong vs. where it falls short, paired with sound discernment in its application
Ability to use AI agents to quickly project multiple approaches, compare tradeoffs, and converge on the best solution without shipping “AI-shaped” code.
