Project Manager

About this role

We are seeking a Project Manager to join our Payments Gateway group in the UK. This role sits alongside our Protocols team, which owns the services that manage connectivity between the NMI platform and external card acquirers and payment processors. Certifying those connections is what turns engineering work into live, revenue-generating processor integrations, and it is one of the most common places where delivery timelines slip.

As Project Manager, you will own the gateway-to-processor certification pipeline end to end. You will track every open certification across our processor portfolio, maintain a clear and current view of where each one stands, and drive each to completion as quickly as the external party will allow. You will be the person who knows, at any moment, what is blocking go-live and who needs to move for it to clear.

About NMI

NMI, a global leader in payment technologies, allows software and sales professionals to deliver payment innovations to their clients without having to build payment expertise in house. NMI enables our partners with choice, and challenges the one-size-fits-all approach to payments. You've probably used NMI in the last 24 hours without even realizing it. We're the platform that powers success for innovative tech created by SMBs, entrepreneurs and fintech startups.

We democratize the latest payments technology so that everyone can realize the benefits of easy payments across the full spectrum of commerce. Our mission is to use our expertise to enable more payments, in more ways and more places. We provide ISOs, Fintech Innovators and Technologists the freedom to focus on what they do best, liberating them from restricted payment solutions and giving them access to the latest payment technology now and in the future.

How We Work - Our Core Values

* Be a Good Person, It's Simple. We treat everyone fairly and with respect. We lead with kindness, humility and integrity. We take the time to understand each other and our customers. And we serve with care, because customers are never a transaction, and always our focus

* Align, Trust & Go. We debate openly, listen carefully and challenge thoughtfully. Once we decide, we move forward together - holding ourselves accountable to our commitments, and focusing on what matters most to our customers. That alignment creates momentum.

* Raise the Bar. Good enough isn't enough. We stay curious, measure everything, stay honest about progress and keep pushing ourselves to think creatively. We drive change, again and again. And leave things better than we found them. When we raise the bar, our customers feel it too.

Key Responsibilities:

• Maintain a single source of truth for all in-flight and upcoming certifications across processors and acquirers, including status, owner, target dates, and outstanding test cases. You will keep this visible to engineering, product, and enterprise sales so certification timing feeds directly into deal and delivery planning.

• Own the relationships with processor and acquirer certification teams. You will be the primary point of contact, manage the cadence of communication, and build the kind of working rapport that gets NMI prioritised when queues are long.

• Negotiate test scope. Certification suites are often larger than a given integration warrants. You will work with processors to scope test cases down to what is genuinely required, challenge redundant or non-applicable cases, and reduce the certification burden without compromising correctness or compliance.

• Escalate and clear third party blockers. When a certification stalls on the processor side, you will drive it forward: chasing responses, escalating through the right channels, and removing dependencies before they become schedule risk. You will treat external delay as something to be actively managed rather than passively absorbed.

• Partner closely with the Protocols engineering team to sequence certification work against development, surface issues early, and make sure test failures get triaged and resolved quickly.

The Ideal Candidate

Has strong experience managing external technical relationships in payments or a comparable regulated, integration-heavy environment. You understand how gateways, acquirers, and processors fit together, and you are comfortable reading certification specifications and reasoning about test cases well enough to negotiate them credibly. You are organised, persistent, and diplomatically relentless, equally at ease coordinating internal engineering teams and pushing an external partner to move faster. You operate with sound judgement in high-stakes environments where reliability, security, and compliance are paramount.

What You'll Be Doing:

• Own the gateway-to-processor certification pipeline end to end, maintaining a single, current source of truth for every open and upcoming certification across processors and acquirers, including status, owner, target dates, and outstanding test cases.

• Take ownership of processor and acquirer certification relationships, acting as the primary point of contact and building the working rapport that gets NMI prioritised when certification queues are long.

• Negotiate test scope with processors, scoping certification suites down to what is genuinely required, challenging redundant or non-applicable cases, and reducing certification burden without compromising correctness or compliance.

• Proactively identify certification blockers and schedule risk, driving each open certification to completion as quickly as the external party will allow.

• Escalate and clear third party blockers, chasing responses, escalating through the right channels, and removing dependencies before they become delivery risk.

• Clearly articulate certification status, timelines,…
