Backend Engineer

Backend Engineer
Location: Bentonville, AR (preferred) but open to remote within US based on skill level
What you'd own: one or more services in a microservices architecture spanning REST APIs, event-driven consumers, and an API gateway
Experience: > 5 years

Interview: Need to clear Infosys internal evaluation & Customer evaluation (hands-on coding is mandatory)

Must have:

• Java (recent LTS e.g. Java 17/21)
• Spring Boot 3.x (REST controllers; reactive/WebFlux for gateway and high-throughput query-service work; dependency injection; auto-configuration patterns)
• Apache Kafka consumer group patterns, event/CDC-style ingestion, producer patterns
• A NoSQL/document database (e.g. Azure Cosmos DB, MongoDB, DynamoDB) including change-feed/streaming-style read patterns, not just basic CRUD
• Working knowledge of at least one relational database (e.g. Oracle, SQL Server/Azure SQL) via JDBC
• Maven or Gradle build tooling, multi-module dependency management
• Comfort designing and maintaining services that support multiple markets/regions without hardcoded assumptions baked into business logic
• Experience with a CI/CD pipeline and Kubernetes-based deployment as a routine part of the development workflow, not an occasional platform-team handoff

Nice to have:

• API gateway experience (e.g. Spring Cloud Gateway)
• Node.js/Express, for teams running a polyglot backend (e.g. GraphQL services, internal tooling servers)
• In-process caching (e.g. Caffeine) and/or distributed caching (e.g. Redis)
• Secrets management tooling (e.g. HashiCorp Vault)

Thanks & Regards,

Pankaj Singh - Team Lead
