About The Role

We're hiring a seasoned engineer to help stand up a newly formed team dedicated to State Tax Registration & Closure — the systems that get Gusto customers registered with state tax agencies when they start operating in a new state, and cleanly closed out when they stop. As a Principal Software Engineer, you'll shape this team's technical direction from the ground up: defining the architecture, evolving legacy registration and closure workflows toward a more scalable and automated future, and partnering closely with Compliance and Operations to keep customers in good standing across every state they touch.

This role starts focused: get State Tax Registration & Closure onto solid technical footing in the first year. From there, we expect your scope to grow — taking on broader technical influence across Company Group as you prove out the team's foundation. If you're excited about building elegant software with far-reaching effects in the modern economy, and about growing your impact alongside a newly forming team, we'd love for you to join us!

About The Team

Company Group builds the products that help small businesses become — and stay — legitimate, compliant companies, tackling the "back office" work that has everything to do with keeping a business in good standing. That spans forming a legal entity, registering and filing with state and local agencies, business insurance, and the ongoing compliance obligations that come with operating across multiple states.

Owns the products that help customers form and maintain their legal entity — filings, registered agent services, annual reports, and the ongoing paperwork that keeps a business in good legal standing.

Start Your Business

Helps first-time founders go from idea to registered, compliant business — entity formation, EIN setup, and the guidance new business owners need to get started with confidence.

Solo

Builds a back-office experience tailored to solo entrepreneurs and S-corp owners, simplifying the compliance and tax decisions that typically require an accountant.

Business Insurance
