Role Summary

We are looking for an experienced Technical Lead to play a pivotal role in building, scaling, and maintaining our core retail backend platforms. In this role, you will focus on the hands-on development of robust, distributed microservices using Node.js and Apache Kafka. 6+ years of software engineering experience, with at least 2+ years specifically focused on building production-grade microservices.

Working closely with our Technical Architect, you will translate system blueprints into clean, production-grade code, drive engineering best practices within the team, and mentor junior to mid-level developers.

Key Responsibilities

Backend & Microservices Execution

• Hands-on Development: Write clean, modular, and highly performant backend services using Node.js and TypeScript/JavaScript.
• Microservices Implementation: Build and maintain scalable services, adhering to established API contracts, service boundaries, and data ownership patterns.
• Resiliency Application: Implement technical patterns for system reliability, including retries, idempotency, circuit breakers, and backward compatibility.
• Testing & Quality: Own code quality by writing comprehensive unit, integration, and end-to-end tests, while actively participating in and leading code reviews.

Messaging & Event-Driven Systems

• Kafka Integration: Implement asynchronous messaging, service decoupling, and data streaming using Apache Kafka.
• Reliability Engineering: Develop robust consumer patterns, managing partitioning, retention, and error-handling strategies such as dead-letter queues (DLQs).

DevOps & Platform Observability

• Containerization: Package and containerize applications using Docker and assist in deploying them to Kubernetes clusters.
• System Visibility: Integrate application telemetry and distributed tracing using tools like Prometheus, Grafana, ELK, or OpenTelemetry for effective production debugging.

Collaboration & Mentorship

• Architect Alignment: Collaborate with the Technical Architect to implement technical standards, frameworks, and non-functional requirements.
• Team Mentorship: Guide and mentor mid-level and junior engineers on coding standards, modern engineering practices, and system design principles.

Required Skills and Experience

• Experience: 5+ years of software engineering experience, with at least 2+ years of hands-on experience building production-grade distributed microservices.
• Core Stack: Strong hands-on experience in Node.js and TypeScript/JavaScript application development.
• Messaging Systems: Solid practical experience with Apache Kafka and event-driven architecture integration.
• Databases: Practical knowledge of relational and/or NoSQL databases such as PostgreSQL, MySQL, MongoDB, or Redis.
• Cloud & Containers: Hands-on experience with Docker, Kubernetes, and cloud platforms (AWS, Azure, or GCP).
• Engineering Standards: Deep understanding of RESTful APIs, software design patterns, secure coding practices, and distributed systems thinking.

Good to Have

• Experience working within the Retail or E-commerce domain (e.g., inventory, order management, checkout, or cart services).
• Experience with API gateways, service mesh, or Kafka Streams.
• Exposure to Domain-Driven Design (DDD) and event sourcing principles.
