    About this role

    The Opportunity

    We’re looking for a Senior Full-Stack Engineer who can take ownership of the codebase and infrastructure. This isn’t just a “build what you’re told” role—you’ll be the primary technical driver of the platform, making architecture decisions, shipping features end-to-end, and ensuring our systems run reliably in production. You’ll work directly with the founder and have real autonomy to shape the product’s technical direction.

    Our Tech Stack

    Layer

    Technologies

    Backend

    Java 8, Spring Boot, Spring MVC, Spring Data JPA, Spring Security, Gradle

    Frontend

    Angular 7, TypeScript, Angular Material, RxJS, Webpack

    Database

    PostgreSQL with JPA/Hibernate, Liquibase migrations

    Infrastructure

    AWS (EC2, RDS, S3, CloudFront), Docker

    Framework

    JHipster (project scaffolding and conventions)

    Monitoring

    Bugsnag (error tracking)

    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
