Description

Position - Backend Engineer Experience: 5 to 7 years Primary Focus: Backend development, bug fixing, API/microservice development, production support Project: Overwatch, a NestJS/Nx monorepo with gRPC-based backend microservices Role Summary We are looking for a backend engineer to work on an existing production-grade codebase involving NestJS micro services, gRPC APIs, PostgreSQL/TypeORM, Redis, Kafka, Neo4j, telemetry pipelines, device management, authentication, alerting, and API gateway services. The person will primarily work on fixing existing bugs, improving backend reliability, and developing new backend features. Since AI coding agents may be used, we do not expect the person to manually remember every syntax detail. However, they must be strong at understanding system behavior, debugging, validating correctness, and making sound engineering decisions. Key Responsibilities Understand existing backend services and business flows across the monorepo. Debug and fix issues in NestJS/gRPC microservices. Develop new backend features in existing services such as auth, user, customer, device, discovery, telemetry, topology, alert manager, and HTTP API gateway. Work with protobuf contracts and ensure API changes are backward-compatible where required. Investigate issues across service boundaries, databases, queues, cache, and infrastructure. Write or update unit, integration, and e2e tests where appropriate. Improve logging, error handling, observability, and operational reliability. Work with PostgreSQL, TypeORM migrations, Redis, Kafka, Elasticsearch, Neo4j, and related backend infrastructure. Collaborate with frontend, DevOps, QA, and product stakeholders to deliver complete features. Document important technical decisions, API changes, and debugging findings. Required Skills 5 to 7 years of backend software engineering experience. Strong experience with Node.js and TypeScript. Practical experience with NestJS or similar backend frameworks. Good understanding of microservices architecture. Experience with REST and/or gRPC APIs. Experience working with SQL databases, preferably PostgreSQL. Experience with ORMs such as TypeORM. Familiarity with Websockets/SSE. Ability to read and understand existing large codebases. Strong debugging skills across application code, database queries, logs, and distributed services. Familiarity with message queues or event streaming systems such as Kafka. Experience with Docker-based local development. Good understanding of authentication, authorization, validation, error handling, and API security. Ability to write meaningful tests and validate bug fixes properly. Good To Have Experience with Redis caching. Experience with Elasticsearch. Experience with Neo4j or graph-based data modeling. Experience with telemetry, monitoring, network/device management, or infrastructure platforms. Experience with OpenTelemetry, Prometheus, Grafana, structured logging, or health checks. Experience maintaining protobuf/gRPC contracts. Experience using AI coding tools Domain knowledge in Networking What Success Looks Like Bugs are fixed with clear root-cause understanding. New features fit naturally into the existing backend architecture. API, database, and service changes are tested and documented. The engineer can independently investigate issues across multiple backend services. The codebase becomes more stable and easier to maintain over time. Love what this role has to offer?
