[Hiring] Senior Backend Engineer @Hauler Hero Inc.

Role Description

We are hiring a Senior Backend Engineer to design, build, and evolve the core backend services that power Hauler Hero’s platform. This is a 100% hands-on senior individual contributor role focused on building scalable, reliable, and maintainable systems used daily by waste hauling companies across North America.

You will work closely with Product, Frontend, and Platform Engineering to ship features, improve system robustness, and continuously refactor existing services as the platform scales. This role requires strong technical judgment, comfort with ambiguity, and clear communication in a remote environment.

AI-First Backend Engineering

We are intentionally building an AI-assisted engineering organization. AI tools are part of the daily workflow, not optional. What this means in practice:

• Daily use of tools such as Claude, Claude Code, Cursor, and GitHub Copilot
• AI-assisted implementation of Spring Boot services, APIs, database migrations, and business logic
• AI-assisted test generation, refactoring suggestions, and code review support
• AI-assisted log analysis, debugging, and issue investigation
• You remain accountable for reviewing, validating, and owning everything AI produces

Speed matters, but correctness, performance, and maintainability matter more. This role is not a fit for engineers who are resistant to AI-assisted development or who rely on AI output without understanding the underlying system.

Qualifications

• 5+ years of experience building production backend systems
• Experience designing and operating systems with distributed data and meaningful scale
• Experience working in Agile or Scrum environments
• Strong experience with Git and GitHub workflows
• Strong proficiency with Spring Boot using Java and/or Kotlin
• Deep experience with relational databases, especially PostgreSQL
• Experience building and maintaining production APIs
• Experience refactoring toward or within microservice architectures

Requirements

• Ability to translate product requirements into technical solutions
• Strong problem-decomposition and debugging skills
• Solid computer science fundamentals and engineering judgment
• Clear written and verbal English communication skills

Nice to Have

• Experience with Node.js or React
• Messaging and communication platforms such as SendGrid or Twilio
• Event-driven architectures
• Geospatial or location-based systems
• Payments or financial integrations
• Background in logistics, fintech, or B2B SaaS

What We Look For

• Ownership and Judgment: You take problems through to resolution, balance pragmatism with quality, and identify and eliminate single points of failure.
• Communication: Clear, proactive written communication in English, comfort working asynchronously across time zones, and willingness to surface risks and tradeoffs early.
• Mindset: Curious, growth-oriented, and adaptable, comfortable with ambiguity and iteration, and willing to refactor continuously as systems evolve.

What Success Looks Like

• Backend services are reliable, scalable, and maintainable.
• Features ship consistently with minimal rework.
• Production issues are diagnosable and resolved quickly.
• Database and API performance scales with usage.
• Strong trust from Frontend, Product, and Platform teams.

Contractor and Location Notes

• This is a contractor role, not full-time employment.
• Senior-level ownership and reliability are expected.
• This role is open to candidates located in Eastern Europe.
• Consistent overlap with U.S. working hours is required.
