Senior Software Engineer - Go

WHAT DO WE DO?

The company offers SaaS companies a completely different approach to their payments infrastructure. Instead of assembling and maintaining a complex stack of payments-related apps and services, we act as a Merchant of Record for our customers. That means we remove 100% of the pain of payments fragmentation. It’s faster, safer, cheaper, and—above all—better.

We’re backed by investors including KKR, FTV Capital, Kindred, Notion, and 83North, and we serve over 10,000 software sellers in 245 territories worldwide.

THE ROLE

Selling online as a software business is a complex process and many components need to work seamlessly to capture revenue and deliver this to sellers. The company manages payments and billing, with a best-in-class developer-first approach, so that we can take this burden from our customers.

The company is a financially-critical system used by a global customer base, processing hundreds of millions of dollars per month, so there is no shortage of interesting challenges. Senior Software Engineers at the company are not just programmers, we are problem solvers. We expect engineers to take initiative, as part of a small team, from an initial concept, scoping, implementation, right through to rollout and ongoing ownership. This requires initiative, creative thinking, and clear communication, as well as strong technical ability.

We often work with a range of other teams including Data/Analytics, Infosec, Platform (SRE), Risk, Finance and many other product teams other than your own. You will collaborate alongside other engineers, product designers, data analysts, and legal and finance experts to have real impact. This is an opportunity for someone who wants to be part of something challenging and transformative, someone who will play a critical role in driving our success.
