Software Engineer in Test

Dispatch Network is building Last Mile 2.0 redefining how urban logistics operates in India. Were designing the new infrastructure for how goods move: faster, smarter, and more sustainable.

Our systems power real-time movement of thousands of riders across cities connecting orders, people, and places with near-zero latency. Were now moving from proven pilots to national scale.

As an SDET (Backend / Platform Reliability), youll help ensure that the distributed systems powering this network are robust, observable, and production-ready. You will design automated testing infrastructure and reliability tooling for highly concurrent systems built in Go and AWS, enabling our engineering teams to ship faster with confidence.

• Design and build automated testing frameworks for backend services written in Go.
• Develop integration and end-to-end tests that validate dispatch workflows, rider allocation, and order lifecycle across services.
• Build tooling to simulate real-world delivery scenarios order spikes, network failures, rider churn, and geo-movement events.
• Develop reusable test harnesses and service mocks to enable reliable local and CI testing.

• Test systems built around event-driven architectures, async workflows, and microservices.
• Validate correctness and resilience of WebSocket streams, event pipelines, and background workers.
• Design tests for high concurrency scenarios and race conditions common in real-time logistics systems.
• Develop reliability tests for failure scenarios such as service crashes, retries, and degraded network conditions.

• Design and run load and stress tests to validate system performance under peak traffic.
• Identify performance bottlenecks across services, APIs, and caching layers.
• Build chaos and failure simulations to ensure dispatch systems remain stable under infrastructure disruptions.
• Collaborate with engineers to improve observability, alerting, and reliability metrics.

• Integrate automated testing pipelines into CI/CD workflows.
• Work closely with backend engineers during design and development phases to ensure systems are testable.
• Act as a first responder for debugging system issues, helping isolate bugs and reproduce edge cases.
• Contribute tools that improve developer velocity and system confidence.

• 35 years of experience as an SDET or backend engineer with strong automation experience.
• Strong programming ability in Go, Python, or similar languages.
• Experience building automated test frameworks or developer tooling.
• Strong understanding of APIs, microservices, and distributed systems.
• Experience testing event-driven or asynchronous systems.
• Familiarity with AWS environments and cloud-native systems.
• Strong debugging and systems thinking mindset.

• Experience with load testing tools such as k6, Locust, or Gatling.
• Experience testing WebSocket systems or real-time applications.
• Familiarity with Kafka, Redis, and event streaming systems.
• Experience building internal developer tooling or CI/CD automation.
• Exposure to logistics, mobility, or marketplace platforms.
