Senior Software Engineer, Payments
Tabs is the leading AI-native revenue platform for modern finance and accounting teams. Tabs agents automate the entire contract-to-cash lifecycle, including billing, collections, revenue recognition, and reporting, to help teams eliminate manual work and accelerate cash flow.
High-growth companies like Cursor and Statsig rely on Tabs to generate invoices directly from contracts, reconcile payments in real time, and automate ASC 606 compliance.
Founded in 2023, Tabs has raised over $91 million from Lightspeed Venture Partners, General Catalyst, and Primary. The team is headquartered in New York and brings deep expertise in finance and AI.
About the Role
Tabs is seeking a Senior Software Engineer specifically focused on building out custom payments workflows and integrations with payment service providers. As a member of our early-stage startup, you’ll have the opportunity to shape the direction of the company and make a meaningful impact on our success.
How We Work
We work hard. Two-week sprints based on defined goals with short feedback cycles. Built around intra-month product releases.
We work smart. Get in front of the customer, use both data and customer feedback to drive decisions, while keeping the bigger picture in mind. Hash out your ideas with other smart engineers who are dedicated to coming up with great solutions.
We work together. In-office culture with people you want to work with. Lots of whiteboard space. Expense lunch and dinner when in the office, and bagel Fridays!
What You'll Do
Be our payments expert as we build out systems that support multiple PSPs and other exciting similar payment opportunities. There are a lot of moving pieces that have to line up and you’ll own and drive significant projects that make it work.
Work closely with other engineering teams to make sure the entire revenue lifecycle delivers a frictionless billing and payment experience for our merchants and their customers.
Put AI to work everywhere it can move the needle, whether it’s product automation, business process improvement, or the team’s day-to-day workflow. We're dealing with our customers' revenue, so we use AI aggressively while also getting the numbers exactly right.
Level up the engineers around you. The team's about 30 today with a good range of experience and backgrounds, and we’re growing fast. You'll be someone people look up to as you set the technical bar, mentor and learn from those around you, and shape the kind of culture we want as we get bigger.
About You
You’ve been building software professionally for 5+ years and shipped high-impact products with a specialization in building payments systems with at least a couple of Payment Processors.
You've led big, complex system design before, ideally somewhere that was moving and growing fast.
You're hands-on with modern languages and frameworks. You still like being in the code, not just talking about it.
You've got a strong grip on the fundamentals like algorithms, data structures, and distributed systems. You know how to apply them where they actually matter.
You’re genuinely excited about AI, already using it, testing its limits, and keeping up with the latest advancements.
Ambiguity doesn't slow you down. You thrive in the early, undefined stage of a problem where you get to shape the answer rather than follow a spec.
You're the kind of engineer other engineers want to learn from, and you truly enjoy that aspect of the role.
Not sure you tick every box? Apply anyway. If you're excited about what we're building, we want to hear from you.
Tech & Tools
Day to day, you'll be in Next.js, Nest.js, TypeScript, and React.
You'll have a wide range of GenAI systems and tooling to build with, and a lot of freedom in how you use them.
We run on AWS and Vercel, with Datadog and Sentry for observability, and Stripe and Plaid powering payments.
For everything else, we use modern tools like Slack, Notion, Linear, and Google Workspace.
Location: NYC, 5 days onsite
