Full-stack web application developer

Who are we?

Toolkit is a fast-growing environmental technology company that has developed a suite of applications used by industrial facilities to manage environmental compliance.

Our platform includes applications for managing environmental permits and compliance obligations, calculating and tracking air emissions, evaluating regulatory applicability, completing TRI and Tier II reporting, managing hazardous waste, tracking chemical inventories, preparing regulatory reports, and delivering employee training. These applications support complex environmental compliance programs for large manufacturers operating facilities across the country. We've also developed Ivy, an AI assistant integrated into our platform that helps users navigate regulatory requirements, analyze facility data, and complete tasks within our applications.

We're looking for a full-stack developer to support, maintain, improve, and expand these applications. You'll work across an established and growing software platform, developing new features, improving performance and usability, resolving issues, integrating shared functionality between applications, and helping us introduce new AI capabilities.

This role combines traditional software development expertise with the opportunity to help build and grow a cutting-edge compliance software suite. You’ll also collaborate with our affiliated environmental and sustainability law firm and air dispersion modeling group, giving you exposure to the full spectrum of environmental compliance, legal strategy, and technical innovation.
