About the role
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.
- 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.
