Senior Full Stack Engineer

We're looking for senior full stack engineers who will own and build out new product lines such as input tax, withholding tax, e-invoicing, and tariffs as well as mission-critical parts of the Sphere platform.

Within weeks, you'll ship mission-critical features that clients will use daily, own and manage a feature, and drive measurable outcomes. You'll work directly with customers to improve and optimize key components of the platform.

Within months, you'll own the end-to-end development of new product lines that will help build out our AI-native revenue-based compliance platform. You'll lead and mentor additional engineers in component areas that you have worked in.

You'll thrive here if you're a dog who's been underestimated, gone through struggle, and never stopped running. You have a chip on your shoulder and enormous drive. You look at Stripe, Deel, and Flexport all punting on compliance and think: good, that means the opportunity is ours. Hunger beats pedigree.

You own it end to end. Give you a goal and you figure out your own path. Small team, global surface area , everyone owns a domain that would be a full team at a larger company. No one tells you how.

You believe speed and accuracy are both possible. We're building a complex product that requires robustness and 100% uptime, and we have to build at our customers' pace. Move fast. Don't break things. Both.

Being in the room is a feature, not a cost. Five days in SF isn't a policy, it's how the work gets done. The speed and density of collaboration we need doesn't survive over video.
