About the Role

We build production web interfaces for clients, and we care about how they feel, not just whether they work. As a Senior Frontend Engineer, you build the React / Next.js interfaces that people rely on every day, with a real eye for detail, accessibility, and performance.
You'll work inside a Monks delivery team alongside design, product, and backend engineers, owning the experience end users actually touch.
We're all-in on agentic engineering. Tools like Claude Code and Codex are part of our everyday workflow, and we're looking for people who are genuinely fluent working alongside AI coding agents and excited to push those practices further.

Key Responsibilities

• Interface Development: Build responsive, accessible interfaces in React / Next.js and TypeScript.
• Component Architecture: Turn designs into clean, reusable, and well-structured components with solid design-system sensibilities.
• API Integration: Integrate with backend APIs and handle real-world states gracefully.
• Code Quality & AI Review: Review code—including AI-generated code—for quality, consistency, and alignment with engineering standards.
• Performance & Accessibility: Keep performance, responsiveness, and accessibility high across the entire product.
• End-to-End Collaboration: Work tightly with design, product, and backend teams to ship features end to end.

About You

Competencies

• Craft-Minded: You care deeply about the small details that make an interface feel right.
• User-Focused: You build for the people using the product, not just to satisfy a static spec.
• Pragmatic Problem-Solver: You balance polish, technical rigor, and shipping deliverables on time.
• Clear Communicator: You work tightly with design, articulate concepts clearly, and speak up early.

Qualifications & Skills

• Experience: 5+ years of relevant experience in frontend development with strong React, Next.js, and TypeScript.
• Core Technical Skills: Strong modern CSS, responsive layout, accessibility fundamentals, and solid component architecture.
• API & Testing: Comfortable integrating and debugging against APIs, backed by good testing habits.
• Environment & Tools: Comfortable in a fast-paced, agile consulting environment. Fluent in working alongside AI coding tools (e.g., Claude Code, Codex).
• Language Proficiency: Strong English communication skills.
• Bonus Skills (Extra Credit):
• Experience building data-dense dashboards or data visualizations.
• Real fluency with Figma and design handoff processes.
• Animation and interaction-design chops.
• Experience designing UX for AI-powered products.
• Open-source work you're proud to share.
