Ready to find out how far you can actually go?

DataMap is an AI first company. Every engineer here works with AI in the loop, and it changes the math on what one person can deliver. Work that used to take a team of five now takes one engineer who knows how to direct the tools. We put that leverage in your hands early and expect you to use it. A growing share of what we deliver has AI at the center of it rather than bolted on the side, and the enterprises we work with are still trying to figure out what that means for how they run. We are the ones they call.

We build and implement financial and operations software for some of the largest companies in the world, including Google. We're a Microsoft, Coupa, Boomi, SAP and Oracle partner, and most of our work sits where business process meets system design.

Most entry level engineering jobs hand you a ticket queue and a five year wait for anything interesting. This is not one of those. The engineers starting with us now will spend the next decade building things that don't have a name yet. If you like figuring out how to make systems talk to each other, and you'd rather learn that on real client projects than in a training sandbox, this is where you find your ceiling.

The Integration Engineer builds and supports the middleware and custom applications that connect our clients' systems. Day to day that means Boomi, Workato, TypeScript and Azure, moving data between platforms like Coupa, NetSuite, SAP, Workday and Dynamics 365.

Not all of it is middleware. A good portion of our work is custom web applications: supplier portals, approval dashboards, reporting front ends, internal tools. Those are built in TypeScript and React and hosted on Azure. You'll move between the two kinds of work rather than being boxed into one.

You'll start with well scoped assignments alongside a senior engineer and take on more as you learn the patterns. Client exposure comes early. Our engineers sit in the requirements meetings instead of picking up tickets three handoffs later.
