Job description

We're looking for a hands-on Senior Software Developer with deep experience building scalable, cloud-native applications. You'll design, build, and optimize services and UIs using Java 21+, Python 3.X, Angular 21, and AWS 2.0, with a strong emphasis on RDS (PostgreSQL/Aurora). You'll collaborate closely with product, architecture, DevOps, and QA to deliver high-quality features in an agile environment. Experience with GenAI (Bedrock, Claude Sonnet) and graph technologies (Amazon Neptune/Graph APIs) is a strong plus. What You'll Do Design & Develop: Build microservices and APIs in Java (preferably with AWS SDK v2) and supporting services in Python. Front-End Engineering: Develop performant, accessible front-end features using Angular (Angular SDK/CLI) and modern TypeScript patterns. Cloud Architecture: Design and optimize cloud-native workloads on AWS (ECS/EKS/Lambda, API Gateway, SQS/SNS, IAM, CloudWatch). Data & Storage: Model, tune, and operate relational workloads on Amazon RDS (PostgreSQL/Aurora); implement robust migration strategies and performance monitoring. Quality Engineering: Champion automated testing (unit, integration, contract, end to end); familiarity with Karate framework is a plus. Security & Compliance: Apply secure coding practices, secrets management, least privilege IAM, and encryption in transit/at rest. Performance & Reliability: Optimize latency, throughput, and cost; implement observability (metrics/tracing/logging) and resilience patterns (circuit breakers, retries, backoff). GenAI & Graph (Nice to Have): Prototype solutions using Amazon Bedrock (e.g., Claude Sonnet), evaluate prompt/response pipelines, and model relationships with Amazon Neptune or Graph APIs. Agile Collaboration: Work closely with product owners and stakeholders; break down epics, estimate work, review code, and mentor engineers.

Requirements

10+ years of professional software development experience. Expert in Java (Java 11+ preferred) and Python for backend/services and tooling. Proficiency with AWS services and tooling (AWS SDK v2 preferred), CI/CD (CodeBuild/CodePipeline/GitHub Actions/Jenkins), IaC (CloudFormation/Terraform). Strong experience with RDS (PostgreSQL/Aurora)-schema design, query optimization, indexing, replication, and operational best practices. Solid front-end experience with Angular (RxJS, state management, Angular CLI, unit/e2e testing). ADK 21+ preferred Strong grasp of RESTful APIs, event-driven architectures, and microservices patterns. Hands-on with automated testing frameworks and practices (JUnit/Testcontainers/pytest; API testing). Familiarity with containerization and orchestration (Docker, ECS/EKS). Excellent problem-solving, communication, and code review skills. Nice-to-Have Experience with GenAI on Amazon Bedrock (model selection, prompt engineering, guardrails, evaluation) and Claude Sonnet. Graph experience with Amazon Neptune and Graph APIs (Gremlin/SPARQL). Prior experience in mortgage/secondary market domains; Fannie Mae project background is a plus. Karate test automation framework for API and E2E testing. GitLab experience (CI/CD pipelines, runners, branching strategies). Terraform for infrastructure-as-code, particularly with AWS resources. Knowledge of security frameworks (OAuth2/OIDC, JWT), and data governance/regulatory compliance. Observability stack: OpenTelemetry, CloudWatch, Datadog, or similar. Education Bachelor's or Master's in Computer Science, Engineering, or related field (or equivalent practical experience).
