Job description

We are seeking a Senior Full Stack Engineer for a contract position (6+ months) based in Rockville, Maryland. This role focuses on designing and delivering UI applications and backend services that power regulatory form filing systems. You will work across Angular micro-frontends, Java-based REST APIs, and AWS infrastructure, while leveraging AI-assisted development tools as a core part of your engineering practice.

Responsibilities

• Design, develop, and maintain Angular micro-frontend applications and backend services (REST APIs, Lambda functions) for regulatory form filing.
• Author and evolve JSON Schema and layout definitions, and build the schema-driven rendering and validation pipelines that consume them.
• Build and support the filing lifecycle — draft creation, amendment, submission, and cross-section and cross-system validation.
• Provide technical leadership and mentorship to less experienced engineers; raise the bar on code quality, performance, and testing across the team.
• Contribute to architecture discussions and technical strategy for modernization; identify and resolve technical risks and cross-team dependencies.
• Support production systems and troubleshoot complex issues, including validation failures, schema/layout mismatches, and filing lifecycle defects.
• Use AI-assisted development tools (code generation, refactoring, debugging, test authoring, schema and layout drafting) as your default working mode, while owning the output and maintaining test coverage and security discipline.
• Build reusable automation — specs, steering rules, agent skills and hooks, code indexers, test generators, review assistants, prompt libraries — that turns one-off AI interactions into repeatable team processes.
• Design agent workflows that are reliable, debuggable, and produce deterministic, testable outcomes using agent frameworks and protocols (tool use, MCP, multi-step reasoning).
• Simplify code and infrastructure; prioritize work that measurably lowers maintenance and migration cost.
• Work independently on broad, ambiguous problems, exercising judgment and avoiding the need for constant direction.
• Help the team set and deliver clear short-, mid-, and long-term goals aligned to the business; treat regulatory and business change as normal.
• Build collaborative relationships with partners inside and outside the team; seek out other perspectives and maintain a disagree-and-commit mindset.

Qualifications

• Required
  • Demonstrated daily, hands-on use of AI-assisted development tools in a production environment, with specific examples of workflows you automated and the time saved.
  • Bachelor's degree in Computer Science, Information Systems, or a related discipline with at least 7 years of related experience, or equivalent training and work experience.
  • Production experience with Angular and TypeScript on a current release line.
  • Strong object-oriented development experience in Java and system design experience for distributed services.
  • Strong hands-on experience building and operating on AWS.
  • Computer science fundamentals: algorithm design, data structures, complexity analysis, and problem solving.
  • Angular with TypeScript in strict mode, staying close to current Angular versions.
  • RxJS for reactive state management and data flow.
  • JSON Schema authoring (draft-07) and schema-driven UI rendering.
  • Angular Formly or comparable dynamic form engine.
  • Micro-frontend architecture (Angular Elements, multi-project workspace).
  • Complex form behaviors: conditional visibility, cross-section copy, array-based schedules.
  • Playwright for end-to-end testing; Karma/Jasmine for unit testing.
  • SCSS, responsive layouts, and accessibility compliance.
  • Java with Spring Boot (validation engine and data collection services).
  • Spring Expression Language (SpEL) for assertion-based validation rules.
  • RESTful API design and microservices architecture.
  • AWS services: S3, Lambda, SQS, SNS, API Gateway.
  • Observability and troubleshooting: CloudWatch, CloudTrail, X-Ray.
  • Infrastructure as
