Software Engineer, Billing Engine

About Orb

Orb is on a mission to revolutionize billing infrastructure for the modern era of AI and software. We empower businesses to align their monetization with product usage—whether through seats, consumption, feature limits, or hybrid pricing models. Our developer-first, data-driven approach enables companies to automate their billing processes and adapt their pricing strategies with ease.

With Orb, revenue workflows are seamless for every team: developers love our intuitive API and extensibility, product managers iterate on pricing and packaging faster, finance teams gain fine-grained reporting for revenue recognition, and customer-facing teams build trust through billing transparency. Companies like Vercel, Pinecone, and Replit rely on Orb to power their most critical revenue initiatives.

Backed by $44.1 million in funding from top investors like Mayfield, Menlo Ventures, and Greylock, we’re building a hybrid, in-office culture in downtown San Francisco (3 days/week). Our team thrives on collaboration, focus, and kindness, with a shared commitment to solving high-impact problems for our customers. At Orb, every team member drives meaningful impact, and we’re just getting started.

• Collaborate across functions within and beyond the Billing Engine team – from PM and design, to sales and customer success – to shape our product strategy, and deliver customer value from concept to implementation.

• Learn from a talented peer group, and share your expertise
