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.
