How Youll Spend Your Time

Modern Software Development

• Design & Build: Architect and implement Spring Boot microservices and RESTful APIs with best practices for domain-driven design, scalability, reliability, maintainability and provide technical leadership in the decomposition of legacy or monolithic systems into well-bounded, cloud-native services.
• Event Driven Systems: Deliver features using event driven architecture (Kafka, SNS/SQS/Kinesis), including publish/subscribe patterns, idempotency, retries, and error handling.
• Data & Storage: Model schemas and access patterns for SQL Server, PostgreSQL, MongoDB, and Redis; optimize for correctness, performance, and cost.

Agentic AI-First Engineering

• Develop using AI assisted workflows with tools such as GitHub Copilot, Amazon Q/Kiro, and Claude to accelerate coding, refactoring, documentation, and test generation.
• Leverage agentic patterns for multistep tasks such as feature scaffolding, modernization, dependency analysis, and CI/CD interactions-with appropriate human in-the loop (HITL) controls.
• Apply AI-assisted PR review and security scanning, validating suggestions with engineering judgment and secure by design principles.
• Continuously evaluate and improve how AI tools are used across the SDLC to increase throughput, quality, and developer experience.
• Review and validate AI-generated outputs to ensure security, correctness and standards alignment.  

Quality, Delivery & Operations

• Quality Engineering: Own testing strategy-unit, integration, and contract tests-while enforcing CI quality gates.
• CI/CD & Automation: Help shape next generation pipelines as we transition to AWS EKS and Serverless Lambda.
• Observability & SRE: Instrument services using New Relic; define SLIs/SLOs and participate in a minimal on-call rotation.
• Security by Design: Follow secure coding practices and remediate findings; PCI & SOX awareness is helpful.
• Technical Leadership: Lead service-level architecture decisions, including API design, data models, messaging patterns, mentor peers, guide pull requests with a high bar for craftsmanship and provide AWS deployment strategies.
• Serve as the primary escalation point for complex technical challenges impacting delivery and balance speed, quality and sustainability to maintain predictable delivery outcomes.
• Operate What You Build: Practice build it/run it ownership from development through production.

Education & Experience Requirements

• Proficiency with SQL Server or PostgreSQL.
• Strong test discipline (unit/integration/contract), CI/CD pipelines, and code review excellence.
• Experience with observability tools (New Relic, Datadog, Splunk, etc.) and incident response.
• Experience with Postman to build, test, monitor and document APIs.

Nice-to-Have

• Practical experience applying domain-driven design tactical concepts: bounded contexts, aggregates, entities, value objects into hexagonal microservices.
• Securing APIs with Spring Security and OKTA
• Familiarity with AI-assisted development tools (GitHub Copilot, Amazon Q/Kiro) and DevSecOps practices.
• Experience building APIs integrated with Kong API Gateway, Apigee, or similar API Gateway and the testing of APIs with Kong Insomnia.
