Senior Full stack Engineer

At Anchor, we’re fixing something that should’ve been solved years ago.

Getting paid.

While consumers enjoy seamless subscriptions and automatic payments, service-based businesses are still stuck chasing contracts, invoices, approvals, and cash. We think that’s broken, so we built Anchor.

Anchor turns the entire contract-to-cash process into something effortless.

No manual work. No chasing. No friction.

Just a smarter way for businesses to get paid on time, every time — and finally focus on growing, creating, or even taking a well-deserved day off.

Our customers often tell us: “Why didn’t someone build this sooner? This is a game-changer.”

We’re a fast-growing fintech company, backed by top investors, building a product that genuinely changes how businesses operate. If you’re excited about building high-impact technology, care deeply about quality, ownership, and innovation, you’ll feel at home here.

So, what are we looking for?
