[Hiring] Senior Full-Stack Software Engineer @Particle41

Role 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.

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

Qualifications

• 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
