NMI

NMI is a payments technology company that builds the infrastructure businesses use to take and manage card and digital payments. Its core focus is on making payment acceptance work reliably across different channels and systems, while handling the complexity that sits behind the scenes, such as connecting to payment processors, supporting multiple payment methods, and providing the tooling needed to run payment operations day to day. For job seekers, it is the kind of company where the product is mission critical for customers, and where quality, security, and uptime are central to how the business operates.

The company primarily serves organisations that need to offer payments as part of their own services, rather than one off merchants looking for a simple checkout button. That typically includes payment service providers, independent sales organisations, fintechs, software platforms, and larger merchants that want more control over their payments stack. In practice, NMI’s customers are often building payment experiences for other businesses, so the platform has to be flexible and configurable, and it has to work across a wide range of use cases and regulatory environments.

Within the SaaS ecosystem, NMI sits in the payments and fintech layer, providing the platform components that other software products depend on. It operates in a space where integrations matter, from gateways and processors to fraud tools and alternative payment methods, and where trust is earned through consistent performance and careful handling of sensitive data. The work tends to be a blend of SaaS platform engineering and financial infrastructure, with the added complexity of supporting partners and customers who may have their own technical teams and integration requirements.

People who thrive at NMI are likely to be those who enjoy solving practical, high impact problems in distributed systems and APIs, and who are comfortable working in a domain with strict expectations around security and compliance. Engineering roles may suit candidates with experience in backend development, payments integrations, reliability engineering, and platform operations. Product, implementation, and customer facing roles are also likely to value strong communication skills, an ability to translate technical detail into clear outcomes, and a mindset geared towards long term customer success, because payments issues tend to be urgent and closely tied to revenue.

What may appeal to prospective employees is the chance to work on a platform that sits at the centre of how money moves for many businesses, with problems that are tangible and measurable. Payments can be a demanding domain, but it also offers clear feedback loops, meaningful technical challenges, and an environment where attention to detail is valued. If you are looking for a SaaS business where your work supports critical infrastructure and where building dependable systems is part of the culture, NMI is likely to be a strong fit.
