About Hauler Hero

Hauler Hero builds the operating system for residential and commercial waste haulers, including dispatch, routing, billing, payments, customer management, reporting, and the driver app that ties field operations together.

Our customers are private hauler owners, operators, and municipal waste leaders running essential services every day. Many are still managing their businesses through paper tickets, whiteboards, spreadsheets, disconnected systems, and legacy software. The result is missed revenue, messy routes, limited visibility, and too much time spent fighting fires instead of growing the business.

Today, we serve 240+ haulers across the country and are scaling quickly. We are a well-funded, fast-moving vertical SaaS company bringing modern software to an essential industry where the customer need is clear and the opportunity is large.

Role Summary

We are hiring a Senior Frontend Engineer to be a core individual contributor on our web application.

This is a hands-on role with 80% or more of the time focused on coding and building high-quality, production-grade user interfaces used daily by haulers and operators in the field.

You will work closely with Product, Design, and Backend Engineering to ship features quickly while maintaining a high bar for quality, performance, and usability. This role requires strong ownership, clear communication, and the ability to operate independently in a remote environment.

AI-First 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, refactoring, test generation, and boilerplate

You focus on architecture, UX decisions, edge cases, and quality

You review all AI-generated output with a trust-but-verify mindset

This role is not a fit for engineers who are resistant to AI-assisted development or who rely on AI output without understanding the code being produced.
