Senior Front End Engineer

About the Role

We are looking for a problem-solving Senior Frontend Engineer with deep expertise in React, Javascript, TypeScript, and state management who thrives in tackling complex technical challenges. In this role, you'll design and optimize large-scale, data-heavy applications, ensure robust state flows with Redux-Saga, build resilient CI/CD pipelines, and collaborate across teams to deliver high-performance, secure, and accessible web apps.

This is not just about writing componentsits about analyzing tough scenarios, designing scalable solutions, and solving cross-disciplinary problems in a fast-paced environment.

What You’ll Do

• React & TypeScript Design:
• Optimize rendering in high-volume data dashboards using techniques like memorization, virtualization, and code-splitting.
• Migrate and enforce TypeScript types across the codebase to eliminate runtime errors without disrupting development.
• Refactor anti-patterns like direct DOM manipulation into clean, maintainable React patterns.
• State Management & Redux-Saga Expertise:
• Debug and resolve inefficient or parallel saga flows that cause duplicate API calls.
• Design safe persistence strategies for state (e.g. preferences) while protecting sensitive data.
• Standardize error handling models across all sagas for consistency.
• Testing & CI/CD Problem Solving:
• Stabilize flaky unit and integration tests by redesigning mocking strategies for async flows.
• Troubleshoot intermittent CI failures and differentiate between environment issues and flaky code.
• Implement pre-commit GitHub Actions ensuring linting, type-checking, and coverage thresholds.
• Resilience in API Integration:
• Safeguard the UI against breaking backend changes with resilient typing and fallback UIs.
• Implement intelligent retry mechanisms with Redux-Saga, distinguishing between retryable and non-retryable errors.
• Performance, Accessibility, and Design Systems:
• Reduce bundle sizes and improve Lighthouse accessibility scores without slowing delivery timelines.
• Lead safe migrations to new design systems (e.g. Carbon Design updates).
• Optimize complex UI components (e.g. dropdowns with 1000+ items) for responsiveness at scale.
• AI-Assisted Development with Discipline:
• Use tools like GitHub Copilot/ChatGPT responsibly by reviewing outputs for correctness, security, and maintainability.
• Create workflows where AI assists, but engineers own the solution quality and standards.
• Cross-Team Coordination & Leadership:
• Drive adoption of stricter TypeScript/ESLint standards and present tradeoffs to gain team alignment.
• Collaborate with QA, backend, and product teams to handle large-scale Redux state changes mid-sprint without disrupting delivery.

What We’re Looking For

• Strong hands-on expertise in React (Hooks, performance optimization, component design) and TypeScript.
• Proven track record in Redux-Saga, async flows, and state management at scale.
• Ability to design solutions that balance performance, accessibility, and maintainability.
• Advanced debugging skills across the stack (frontend, API layer, CI/CD pipelines).
• Experience with Vitest, GitHub Actions, and CI/CD automation.
• Strong problem-solving and analytical mindset; you see edge cases before they break production.
• Proactive communicator who thrives in cross-functional collaboration.

Nice to Have

• Experience with design systems like Carbon or Material UI.
• Familiarity with API versioning/schematization to handle evolving backend contracts.
• Exposure to AI-assisted coding workflows in production teams.

Why Join?

• Solve real-world, high-impact performance and state management challenges.
• Work on large-scale, data-driven applications with cutting-edge tech.
• Join a culture that values code quality, continuous learning, and innovation.
• Make a direct impact by driving design decisions and problem-solving strategies across the team.
