Job description

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

Requirements

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
