Lead Frontend Developer - React.js/TypeScript
First seen by Alion on Nov 4, 2026.
We're looking for a Lead Front-End Developer who can own our consumer-facing product experiences end to end. What we need is someone who has built polished, high-performance B2C products at a startup, knows how to ship fast without cutting corners, and can raise the bar for a growing front-end team.
Key Responsibilities :
1. Front-End Architecture :
- Define and evolve the front-end stack, patterns, and conventions.
- Make decisions on state management, component design, performance strategy, and build pipelines.
- Build and maintain scalable, reusable components and patterns that support multiple products and use cases.
2. B2C Product Development :
- Build responsive, mobile-first web applications that serve thousands of merchants and end users.
- Obsess over load times, interaction quality, and polish.
3. Team Leadership :
- Lead and mentor a small team of front-end developers.
- Run code reviews, establish standards, and create an environment where engineers grow.
4. API Integration :
- Work with back-end teams to design and integrate RESTful APIs and own the contract between front end and back end.
5. Design Collaboration :
- Partner with product designers to translate Figma/design specs into pixel-perfect, accessible interfaces and contribute to and maintain a shared design system.
6. Quality & Testing :
- Champion front-end testing culture using Jest, React Testing Library, or Cypress and ensure critical user flows are covered.
7. Performance :
- Monitor and optimize Core Web Vitals, bundle sizes, and rendering performance and set up tooling to catch regressions early.
Tech Stack :
- Deep expertise in the first two is non-negotiable; the rest you should be comfortable with or ready to pick up quickly.
- Must-have : Next.js, Tailwind CSS
- Core : React, TypeScript, HTML5, CSS3, JavaScript (ES6+)
- Testing : Jest, React Testing Library, Cypress (or equivalent)
- Tooling : Git/GitHub, CI/CD pipelines, Webpack/ Turbopack
- Collaboration : JIRA, Confluence, Agile/Scrum workflows
- Nice to have : Familiarity with Figma, analytics/A/B testing platforms, monorepo tooling
Qualifications & Experience :
- B.Tech, B.E., MCA or equivalent.
- 6 - 8 years of hands-on front-end development experience, with at least 2 years in a lead or senior role.
- Experience working at a startup; you thrive in environments where you wear multiple hats, make trade-offs independently, and ship under ambiguity.
- A strong portfolio of B2C products - apps or web experiences used directly by consumers or small business owners.
- You think in systems, not just screens, and you care about reusable components, consistent patterns, and maintainable codebases.
- Excellent communication skills - you can articulate technical trade-offs to engineers, designers, and non-technical stakeholders alike.
- A critical thinker who debugs complex issues methodically and proposes pragmatic solutions.
- You take pride in mentoring others and building a strong engineering culture.
