What You’ll Do
- Own the full application lifecycle—backend APIs, frontend UI, database schema, CI/CD pipelines, and production infrastructure on AWS
- Design, develop, and ship new features across the Java/Spring Boot backend and Angular frontend
- Manage and optimize our PostgreSQL database, including schema migrations (Liquibase), query performance tuning, and data integrity
- Maintain and improve AWS infrastructure: EC2, RDS, S3, CloudFront, and related services
- Collaborate directly with the founder to translate business requirements into technical solutions
- Improve code quality through testing, code reviews, refactoring, and documentation
- Troubleshoot and resolve production issues quickly and thoroughly
- Evaluate and adopt modern tools, frameworks, and practices to keep the platform competitive
- Leverage AI-powered development tools (e.g., Claude, GitHub Copilot) to accelerate delivery and improve code quality
What We’re Looking For
Required
- 5–8+ years of professional software development experience
- Strong proficiency in Java and the Spring Boot ecosystem (Spring MVC, Spring Data JPA, Spring Security)
- Solid front-end skills with Angular (TypeScript, RxJS, component architecture)
- Deep experience with PostgreSQL or similar relational databases—schema design, migrations, query optimization
- Hands-on experience with AWS services (EC2, RDS, S3, CloudFront, IAM) or comparable cloud platforms
- Comfortable working across the entire stack and owning infrastructure alongside application code
- Strong English communication skills (written and verbal) for daily collaboration
- Self-directed and proactive—you take initiative, flag issues early, and don’t wait to be told what to do
- Available during US business hours (Central Time preferred, but flexible within the Americas)
Nice to Have
- Experience with JHipster-generated applications
- Familiarity with Liquibase for database change management
- Experience with Docker, CI/CD pipelines (GitHub Actions, Jenkins, or similar)
- Background in marketplace platforms, subscription billing, or scheduling systems
- Exposure to mapping/GIS tools (Google Maps API, geospatial queries)
- Interest in or experience with AI-assisted development workflows
