About BeeHyv

BeeHyv is a boutique software engineering firm helping enterprises and product companies modernize systems, build cloud-native platforms, and adopt AI / GenAI solutions. We bring the agility and craftsmanship of a high-end engineering partner, trusted by both startups and global

organizations.

The Role

We are looking for a Senior Frontend Developer (SDE III) who can combine strong React expertise with architectural thinking and leadership in execution. You will own large features end-to-end — from design to delivery — and influence the frontend architecture, tooling, and performance optimization strategy.

This is a senior individual contributor role with opportunities to mentor engineers, improve code quality and shape BeeHyv’s frontend engineering best practices.

What You’ll Do

Architect, design, and develop React-based web applications at scale.

Drive initiatives for frontend modularization, performance optimization, and design system standardization.

Collaborate with backend engineers to define data contracts and optimize API integrations.

Lead code reviews and mentor SDE I / SDE II developers on design patterns and frontend principles.

Contribute to architectural decisions — SSR / SSG strategies, caching, and micro-frontend integration.

Set up and enhance tooling pipelines for linting, type safety, testing, and deployment.

Define and monitor frontend observability metrics (performance, stability, accessibility).

Partner with design teams to evolve component libraries and ensure brand consistency.

Stay up-to-date with frontend ecosystem trends and recommend adoption of relevant innovations.

What We’re Looking For

6–10 years of frontend development experience with 3+ years in React.

Deep understanding of React internals, reconciliation, and rendering performance.

Strong proficiency in TypeScript, React hooks, and modern state management patterns.

Experience in SSR frameworks (Next.js) and frontend build tools (Vite, Webpack).

Strong grasp of frontend architecture — modularization, monorepos, CI / CD, and versioning.

Experience leading large-scale UI refactors or design system rollouts.

Hands-on experience with testing frameworks (Jest, Cypress, Playwright).

Understanding of web performance optimization (Core Web Vitals, Lighthouse audits).

Exposure to accessibility (a11y) and compliance standards.

Excellent debugging and profiling skills for production-grade apps.

Nice to Have

Familiarity with micro-frontends, Nx / Turborepo, or design token frameworks.

Experience integrating feature flagging or A / B testing frameworks.

Exposure to observability tools like Sentry, Datadog, or LogRocket.

Experience using AI-assisted development for productivity and code quality.

Experience mentoring teams in frontend engineering maturity models.

Why Join Us

Lead the development of high-performance, scalable frontend applications.

Influence the frontend architecture roadmap and engineering direction.

Work with top-tier engineers across multiple disciplines — backend, DevOps, AI, and data.

Build with modern React tooling and industry best practices.

Thrive in a fast-paced, engineering-first culture with continuous learning and ownership opportunities.

Opportunity to shape BeeHyv’s frontend excellence across projects and products.
