Senior Software Engineer - Backend (GO)

We are seeking a Senior Software Engineer - Backend to design and build scalable backend systems that power Android-first mobile applications. The ideal candidate will have strong backend engineering expertise, experience supporting mobile applications, and a passion for building high-performance, reliable distributed systems that operate efficiently under constrained network conditions.

You will work closely with Android developers and cross-functional teams to build APIs and backend services that enable seamless mobile experiences, including offline synchronization, scalability, and high availability.

Responsibilities:

• Build and own backend services powering Native Android applications and offline-first workflows.
• Partner with mobile engineers to design reliable mobile-to-cloud APIs and synchronization mechanisms to cloud APIs and synchronization mechanisms.
• Drive backend decisions around scalability, reliability, performance, consistency, and observability.
• Own backend components from architecture through deployment, monitoring, and production support.
• Participate in API and data-model design with mobile, architecture, and product teams.
• Support UAT, phased rollouts, production releases, and time-sensitive delivery milestones.

Requirements:

• 4-7 years of hands-on backend engineering experience building production-grade services and APIs.
• Strong programming experience in Go (Golang), with solid knowledge of data structures, algorithms, design patterns, and software engineering principles.
• Experience designing high-performance and scalable backend services.
• Strong understanding of REST/gRPC APIs, API design, authentication, authorization, and service-to-service communication.
• Experience supporting offline-first and intermittently connected applications, including synchronization, conflict resolution, idempotency, retries, and eventual consistency.
• Strong experience with databases, caching, key-value stores, and messaging/event-driven systems.
• Strong understanding of distributed systems, concurrency, fault tolerance, scalability, and reliability.
• Experience handling high transaction volumes and large datasets.
• Strong understanding of observability, including logging, metrics, tracing, and monitoring.
• Strong problem-solving skills and ability to work closely withMobile/Android, Architecture, Product, and DevOps/Cloud teams.

Good to Have:

• Experience with GCP, Docker, and Kubernetes.
• Experience with Kafka, Pub/Sub, or similar messaging systems.
• Experience designing mobile synchronization systems, including delta sync, batching, and background synchronization.
• Experience optimizing APIs for mobile network constraints, including payload optimization and compression.
• Experience with backend performance testing, profiling, and capacity planning.
• Experience in retail, logistics, field service, or enterprise applications.
