You will own solutions from architecture and API design through implementation, deployment, and production operation, and modernize cloud-native applications on AWS to improve scalability, resilience, and operational readiness. You will also integrate with API gateways, identity providers, databases, and partner systems, and lead root-cause analysis when complex issues arise.\nKey Roles & Responsibilities:\nDesign, develop, test, deploy, and maintain Java and Spring Boot applications, microservices, and secure REST APIs.Own technical solutions from architecture and API design through implementation, deployment, and production operation.Build and modernize cloud-native applications on AWS, improving scalability, resilience, maintainability, and operational readiness.Design and implement integrations with API gateways, identity providers, databases, internal platforms, downstream services, and external partners.Apply API security controls, including authentication, authorization, OAuth 2.0, JWT validation, encryption, secrets handling, input validation, and protection of sensitive data.\nDesign maintainable API contracts with appropriate versioning, backward compatibility, idempotency, validation, error handling, and traffic protection.\nBuild fault-tolerant services using resilience patterns such as timeouts, retries with backoff, circuit breakers, bulkheads, rate limiting, graceful degradation, health checks, and failover.\nImprove software quality through automated unit, integration, component, contract, and performance testing.\nStrengthen observability using structured logging, metrics, tracing, correlation identifiers, dashboards, service-level indicators, and actionable s.\nDiagnose complex application and integration issues, lead root-cause analysis, and implement corrective actions that prevent recurring failures.\nContribute to CI/CD automation, automated quality controls, vulnerability remediation, and production-readiness activities.Analyze application performance, capacity, and cloud-resource usage, and implement improvements where they provide measurable value.Participate in technical design reviews, code reviews, requirements refinement, estimation, and solution planning.Identify technical debt and recommend practical improvements to architecture, security, resilience, code quality, and developer productivity.Create clear technical documentation covering architecture decisions, API behavior, integrations, operations, and troubleshooting.Collaborate with engineers, architects, product owners, security teams, and platform teams, and provide technical guidance to other engineers.What you need:\nRequired Skills:\n8+ years of professional software engineering experience, or comparable experience demonstrating senior-level technical capability.Strong hands-on development experience with modern Java, preferably Java 17 or later.Strong experience developing production applications with Spring Boot and the broader Spring ecosystem.Demonstrated experience designing, building, and operating REST APIs, microservices, and distributed systems in production.Practical experience developing cloud-native and containerized applications on AWS.Strong knowledge of API security, including OAuth 2.0, JWT, authentication, authorization, encryption, secrets handling, input validation, and secure coding practices.Strong API design experience, including contracts, versioning, backward compatibility, idempotency, validation, error handling, and traffic protection.Strong knowledge of software architecture, object-oriented design, design patterns, resilience patterns, clean code, and engineering best practices.Experience designing fault-tolerant systems, including failure isolation, recovery, concurrency, consistency, and service-dependency management.Experience applying resilience patterns such as timeouts, retries, circuit breakers, bulkheads, rate limiting, graceful degradation, health checks, and failover.Experience developing integrations with multiple data sources, partner systems, or third-party platforms.Experience with relational databases, SQL, data modeling, transactions, and database performance considerations.Experience creating automated unit, integration, component, contract, and service-level tests.Experience using Git, Linux or Unix, build automation, CI/CD, dependency management, and debugging tools.Strong production troubleshooting, observability, performance analysis, scalability testing, and root-cause analysis skills.Ability to independently lead complex engineering work from problem definition through production delivery.\nAbility to evaluate technical trade-offs and communicate recommendations clearly to technical and non-technical stakeholders.\nDesired Skills:\nExperience with Apigee, AWS API Gateway, or another enterprise API-management platform.\nExperience deploying and operating services using AWS ECS.\nExperience with Terraform, Jenkins, or comparable infrastructure and delivery automation tools.\nExperience with Splunk, Dynatrace, Okta, or comparable observability and identity platforms.\nExperience modernizing legacy applications or designing highly available, multi-region systems.\nExperience with event-driven architectures, messaging platforms, or asynchronous processing.\nExperience with cryptography and secure payload patterns, such as ECDH, ECDSA, HPKE, JWE, digital signatures, or key management.\nExperience developing software for regulated environments or systems that process sensitive consumer data.Experience developing AI-enabled solutions using large language models, retrieval-augmented generation, intelligent automation, or related technologies.Practical experience using AI-assisted
