In Office | Full-time | 2+ Years Experience

ABOUT THE ROLE

We're looking for a Full Stack Developer who thrives on solving complex technicalchallenges and building high-performance, scalable systems. You'll work acrossthe entire stack—from designing intuitive frontend experiences to architectingresilient backend and infrastructure systems.
If you love writing clean, type-safe code, enjoy deep architectural discussions,and can balance technical perfection with practical delivery, this role is for you.

TECHNICAL SKILLSETS

Core Backend (Primary Focus)
• Node.js / Express.js - Building high-throughput APIs and webhook handlers
• Queue Systems - BullMQ, Redis-backed job processing, worker management

• Databases - SQL/NoSQL optimization, indexing, query tuning, connection pooling

• Distributed Systems - Multi-layer caching, data consistency, resilience patterns

• API Design - REST, GraphQL, pagination, rate limiting, versioning

Frontend Development

• React - Hooks, component composition, lifecycle, performance optimization

• TypeScript - Generics, type-safe APIs, type narrowing, strict mode

• Performance - Virtual scrolling, memoization, debouncing, lazy loading

• Real-time - WebSockets, Server-Sent Events, live data updates

• CSS / Design - Custom styling, responsive design, accessibility-first approach

Infrastructure & DevOps

• Deployment - CI/CD pipelines, blue-green deployments, canary releases

• Monitoring - Prometheus, Grafana, structured logging, alerting systems

• Performance - Error tracking, benchmarking, load testing, optimization

Data Engineering

• Real-time Pipelines - Event streaming, data processing at scale

• Consistency - Transaction management, distributed data integrity

• High Traffic - Handling bursts, spike management, graceful degradation

NON-TECHNICAL SKILLSETS

Problem Solving

• Strong analytical skills with clear trade-off reasoning (e.g., "Why Redis over in-memory cache for this use case?")

• Proactively identifying edge cases (What happens when the queue is full? When Redis goes down?) • Designing practical solutions under real-world constraints (time, budget, team size)

Communication

•Writing clear technical documentation (ADRs, API docs, runbooks)

• Explaining complex systems simply (Can you explain connection pooling to a PM?)

• Documenting architectural decisions with context and rationale

• Code that communicates intent through naming and structure

Engineering Judgment

• Knowing when to optimize vs. when "good enough" is sufficient

• Example: Choosing between 100ms vs 50ms latency based on user impact

• Balancing technical debt with feature velocity

• Understanding business priorities alongside technical excellence

Quality & Collaboration

• Designing testing strategies (unit, integration, E2E) that catch real bugs

• Following security best practices (input validation, OWASP guidelines)

• Writing maintainable, convention-driven code that others can understand

• Sharing knowledge through documentation, demos, and mentoring

EXPERIENCE LEVEL

• 2+ years with Node.js in production environments
• Experience with high-volume systems (1000+ req/min preferred)
• E-commerce or logistics experience is a strong plus

WHAT WE OFFER

• Opportunity to work on complex, high-impact systems processing millions of orders

• Collaborative and engineering-driven culture with code reviews and pair programming

• Flexible remote-first working environment

• Competitive compensation: ₹9 LPA

• Learning budget for conferences, courses, and certifications

• Modern tech stack and development tools
