Backend Software Engineer

Responsibilities a. Backend API Development Design, build, and maintain RESTful APIs using Java Spring Boot and Python-based supporting services. Implement business logic across lifecycle management, asset tracking, configuration, and reporting domains. Define API contracts using OpenAPI/Swagger. Implement structured logging, monitoring, and alerting. Write tests for the services you build. b. Authentication and Security Implement OAuth2, JWT, and API key-based authentication. Contribute to a multi-tenant RBAC system governing API access and feature availability. Work with Firebase Authentication for token validation and identity handling. c. Data Layer and Persistence Work with MySQL, MS SQL Server, and PostgreSQL. Design schemas, manage migrations, write and optimize SQL queries and stored procedures. Maintain data integrity and performance in a multi-tenant architecture. d. Event-Driven and Microservices Architecture Implement and extend microservices communicating via message queues (RabbitMQ / Amazon MQ). Build asynchronous message-processing workflows with retry, dead-letter, and error-handling strategies. e. Python Services and Tooling Develop and maintain Python-based services for data processing, ETL pipelines, and backend automation. Write Python scripts and utilities for operational tooling, data transformation, and integration support. f. Third-Party Integrations Integrate with external APIs from dealer management systems, telematics providers, and equipment manufacturers. Handle authentication schemes, payload mapping, data transformation, and failure handling. Document integration contracts and data flows. g. IoT, GIS, and Mapping Work with geospatial data, asset location services, and map-based interfaces. Contribute to services powering geofencing, path replay, and location-based reporting. Requirements a. Technical 6+ years building APIs with Java Spring Boot. 3+ years working with Python in a backend or data-processing context. Strong knowledge of OAuth2, JWT, OpenID Connect, and API security practices. Experience with at least two of MySQL, MS SQL Server, and PostgreSQL. Proficiency in OpenAPI/Swagger. Experience with event-driven architectures and message queues (Kafka, RabbitMQ, SQS, or Amazon MQ). Demonstrated experience writing automated tests (unit, integration, contract). Experience with AI development tools such as Claude Code or Codex. b. Environment and Tools Services run on Linux in production. Comfortable in a terminal — reading logs, tracing processes, debugging environment-level issues. Knows local dev setup thoroughly: builds, containers, and why things break between local and staging. c. Communication Non-negotiable. Cross-timezone work with teammates in Pakistan, Indonesia, and the US. Mostly asynchronous — Jira, Confluence, Slack, pull requests. Advanced level of English. Plain-language technical explanations. Surface problems early. If you go quiet when stuck, this is not the right fit. d. Ownership Small team. Own problems end-to-end. Ask the right questions when requirements are ambiguous. Make architectural decisions when your lead is offline. Context-switch between feature work, production issues, and integration work without dropping things.
