Apply for Senior Full Stack Engineer

About Stratiform

Stratiform Digital is a digital services firm that builds modern, cloud-native software for government and enterprise clients. We take on complex modernization work, moving legacy systems onto maintainable, well-architected AWS foundations, and we hold a high bar for engineering quality, testing, and clear communication.

About the Role

We are looking for a self-motivated Senior Full Stack Engineer to contribute to the migration of a legacy Java Spring Boot / Angular monolith into a modern, cloud-native microservices architecture on AWS. This first phase preserves existing functionality one-to-one (no feature changes), migrating the backend from Java to Node.js and separating it into its own service, with a goal of performance parity (no degradation) on a cleaner foundation. The ideal candidate is equally comfortable in legacy Java codebases and modern Node.js services, brings a strong relational database background, and takes initiative without close direction.

What You'll Do

• Assess and contribute to the decomposition of a monolithic Java Spring Boot application into Node.js microservices on AWS managed infrastructure.
• Read, reason about, and refactor existing Java code: untangle business logic from persistence, identify data access patterns, and prepare services for extraction.
• Build production-quality Node.js/TypeScript microservices with clean data access layers, RESTful APIs, and event-driven integrations.
• Write and maintain comprehensive test suites following TDD: unit, integration, and acceptance tests using Playwright.
• Collaborate with the Technical Lead and Cloud Engineer to implement AWS architecture that leverages managed services for scalability and operational efficiency.
• Contribute to CI/CD improvements and adhere to the team's GitHub Actions workflow standards.
• Work with PostgreSQL on Aurora at production scale: schema design, migrations, and query optimization.
• Document code, architecture decisions, and data flows for long-term maintainability.

What We're Looking For

Java & Legacy System Experience

• Strong Java proficiency, including Spring Boot, JPA/Hibernate, and enterprise integration patterns.
• Demonstrated ability to read, analyze, and refactor legacy Java codebases without introducing regressions.
• Understanding of common monolith anti-patterns and practical strategies for incremental decomposition (e.g., Strangler Fig).
• Experience writing data migration scripts or transformation utilities in Java.

Node.js & Modern Development

• Solid Node.js and TypeScript experience building RESTful and event-driven services.
• Familiarity with modern framework patterns, middleware design, and asynchronous programming in Node.js.
• Experience integrating Node.js services with relational databases (PostgreSQL strongly preferred) and AWS managed services.

Relational Databases

• Strong SQL skills: schema design, query optimization, indexing strategies, and large-scale data migrations.
• Hands-on PostgreSQL at production scale, including Aurora configurations, schema conversions, and performance tuning.
• Understanding of both OLTP and event-sourcing data models in a microservices context.

AWS & Cloud

• Proficiency with core AWS services: Lambda, API Gateway, RDS/Aurora, S3, Step Functions, SQS, SNS, and EventBridge.
• Experience with infrastructure as code (AWS CDK preferred); able to deploy and configure cloud resources independently.
• Strong understanding of CI/CD pipelines using GitHub Actions, including deployment automation to AWS.

Quality & Testing

• Consistent TDD practice; writes unit, integration, and acceptance tests as a standard part of delivery.
• Experience with front-end testing using Playwright.
• High personal bar for maintainability; active participant in code reviews.

Experience & Qualifications

• 7+ years of full-stack engineering experience with demonstrated depth in both Java and Node.js.
• Direct experience contributing to a monolith-to-microservices migration in production.
• Highly self-directed: prioritizes work, makes sound technical decisions independently, and escalates blockers appropriately.
• Bachelor's degree in Computer Science, Information Technology, or a related field (equivalent experience accepted).
• Experience with Angular front-end applications is a plus.
• Prior experience supporting federal or government contracts is a plus.
• AWS certifications are a plus.
