Responsibilities

Own and contribute to architecture and development across products, driving technical excellence in both frontend and backend systems.

Develop and optimize backend API services with test-driven development including advanced caching and messaging for reliability and scalability.

Deliver high-quality frontend experiences using modern frameworks, with strong fundamentals in component-based architectures and state management.

Integrate and support observability, logging, and monitoring to ensure platform reliability and rapid incident response.

Ensure top-tier application security and compliance, applying best practices across frontend, backend, and API layers (authentication, authorization, rate-limiting, OWASP).

Leverage LLMs and AI tools to write, refactor, test, and debug code efficiently, implementing guardrails for reliability.

Participate in design reviews, deep dives, and on-call rotations to support a culture of accountability and operational excellence.

Requirements

4+ years of hands-on software engineering experience building and scaling robust backend systems and high-performance frontend applications.

Strong backend engineering and distributed system design skills, with hands-on experience in API development, data modeling, and systems architecture using Node.js (NestJS preferred), TypeScript, MongoDB, and Redis.

Expertise in backend performance optimization, caching strategies, and event-driven architectures (e.g., Redis, Kafka, Pub/Sub).

Familiar with modern frontend frameworks ( Vue, Angular, React), advanced UI engineering patterns, and CSS libraries like Bootstrap or Tailwind CSS.

Advanced experience with complex state management libraries (e.g., Redux, Vuex, MobX) and architectural design of large-scale application state.

Proven track record of optimizing frontend performance and web vitals at scale, including experience with server-side rendering (SSR), edge, or hybrid rendering architectures.

Familiarity with frontend and backend observability - including monitoring, tracing, error tracking, and performance profiling in production (e.g., Grafana, Prometheus, Sentry, PostHog).
