Software Engineer, Full Stack Developer, Backend Developer

About Check Payroll is broken. It's still running on decades-old infrastructure. We're rebuilding it.

We don't run payroll ourselves — we power the businesses that do. As the inventors of embedded payroll, we're redefining how people get paid and making it easier for those businesses to launch, grow, and thrive.

On our team, you'll use creative problem-solving, critical thinking, and grit to simplify the complexity of payroll for thousands of employers of every size, across all industries. We ignore conventional role boundaries in favor of the unique strengths and values each builder brings to our mission: make paying people simple. Check out our origin story!

Check is far more than just API infrastructure. We’re a springboard for building and scaling payroll businesses. See how it works for our partners.

Engineering Culture at Check Engineering at Check works as one small team with a lot of ownership. We staff engineers on business priorities rather than fixed domains, and when something is stuck, people step in to move it forward instead of waiting on ownership boundaries. AI is central to how we build, and very little of our code is written by hand.

That makes engineering judgment more important: deciding which problem to solve, defining what "done" means, and catching what the AI got wrong. A merged PR isn't the finish line. The work is done when it has had the intended impact.

About this role

As a Software Engineer early in your career, you'll ship real work on the platform that moves money, calculates taxes and runs compliance for thousands of businesses.

What You'll DoBuild and ship software that improves how partners, operators and internal teams run payroll on Check Use AI to learn unfamiliar systems quickly, explore approaches, and write and test code

Own everything you ship, however it was written, so you can explain it, review it critically and debug it in production

Define the impact you're aiming for before you start, then release early, iterate and follow through until you reach itWork directly with engineers, product and operations to understand problems from the people who have them Share what you learn so the team gets better at building with AITake feedback and mentorship well, and keep raising your own quality barWhat We're Looking For High agency and curiosity, with a habit of running at problems and picking up context quickly

Strong engineering fundamentals, so you can reason about systems and tradeoffs without an AI tool doing that thinking for you Hands-on experience building with AI tools, and the judgment to tell plausible output from correct output
