Senior Java Software Engineer

About

• We’re looking for a Full Stack Developer V / Senior Software Developer at Reston, VA / Plano, TX.
• 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.

Responsibilities

• 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 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).
