Key Responsibilities
- 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.
- 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.
- Code Review Assessment
- Recruiter Interview
- Hiring Manager Interview
- Technical Interview
- Culture Fit Interview
