Senior Engineering Manager, Financial Experience

We’re looking for a Senior Engineering Manager to lead Financial Experience (FinXP), the team that builds how practices and patients deal with money at Nelly.

That covers how a patient says yes to a treatment they can’t pay for upfront, and how delivered care becomes an invoice, then a payment, then cash in the practice’s account. You’ll lead a team whose work shows up directly in what practices earn and in what Nelly earns.

The problem space: Practices rarely lose revenue because care isn’t needed. They lose it at two points. Before treatment, patients delay or decline because they can’t pay upfront. After treatment, revenue leaks on its way to cash: invoices go out late or wrong, payments get chased by hand, and billing runs through manual steps. The domain Financial OS closes both gaps. We offer financing at the moment the patient decides, through installment plans and factoring, and we turn every delivered treatment into a correct invoice and cash in the practice’s account. Because we sit where treatment is planned, we know what it’s worth and whether it is converted before we take on the risk, which no bank or payment provider can do. We earn a share of the revenue we help collect, so the practice’s growth is our growth.

The domain has two teams. Financial Platform builds the infrastructure that moves money and keeps compliant records of it. Financial Experience builds everything doctors, practice staff, patients and our own teams touch, across the Doctor Portal, Patient Portal and Backoffice.

About Nelly

We are building the AI-Driven Financial Operating System for European healthcare, solving the biggest challenges for patients and practices. We create what no bank or software platform can handle. Our all-in-one platform transforms chaotic administrative processes into intelligent, automated workflows, from patient care to billing to next-generation payments. Because we truly believe: healthcare should be less about paperwork and more about people.

Why? Because Europe is facing a massive shortage of medical professionals. And if we don't rethink the way practices work, the system won't be able to keep up. With our Series B funding of over €50 million from world-class investors, we are turning our vision into reality.

What sets us apart: We work with the best team, which is why we give everything together every day. We believe in Talent Density, because exceptional people make everyone around them better. At Nelly, we move fast and expect everyone to keep up. Stagnation isn’t an option, which is why we invest heavily in growth. AI is an essential part of how we work at Nelly. We expect you to use it every day and give you everything you need to do so. You get trust and ownership and we expect you to speak up, even when it's uncomfortable.

Joining us, you will:

• Lead, inspire and grow a high-performing team of 3–6 software engineers

• Own hiring for your team, building a team of high-performing engineers

• Work closely with your product manager to build, launch and improve the financial journey iteratively. That starts at the point of decision, with cost plans, credit checks and installment plans, and runs through to collection, with invoicing, dunning and the processing of billing files

• Own the quality, reliability and security of your team's products, delivering highly available production systems that handle sensitive financial and patient data

• Partner with the Financial Platform team to shape the infrastructure your features depend on, and with Nelly's internal teams who use the Backoffice every day.

• Keep your team at the cutting edge of LLM- and AI-based engineering, testing new ideas and tools as they're released

• Stay hands-on, developing alongside your team

• Contribute to engineering-wide initiatives as a member of Nelly's engineering leadership team

What you'll bring:

• 3+ years as an Engineering Manager and 8+ years of overall experience in software development

• A strong technical background designing, building and owning customer-facing full-stack web applications and the back-end systems behind them, with care for usability and the end-user experience

• A track record of iterating very quickly: defining small scopes to test hypotheses, running A/B tests, measuring impact, and using the results to decide what to build next

• Experience with cloud-native development

• A deep understanding of software engineering processes and team management.

• Empathy and excellent communication skills, with product, design and non-technical users alike

Even better if you have:

• Experience with billing, invoicing, payments, lending or other financial products.

• Experience building products for several user groups at once, such as businesses, their staff and their end customers.

• Familiarity with healthcare billing, for example in German dental or medical practices

Our Interview Process:

• Recruiter screening, 30 minutes

• Hiring manager conversation, 30 minutes

• Product interview, 60 minutes

• Onsite interview - System design, Leadership interview and Meet the CTO

What we offer:

• The people you get to work with. You will work alongside the brightest minds we could find, on hard problems, as a team. We take on challenges together and we never forget to have fun doing it.

• Room to grow faster than almost anywhere else. New challenges, more scope, real ownership from day one. We trust you to own it and to speak up when something is wrong. Just do not expect to stand still.

• A yearly learning and development budget, plus the coaching, feedback and internal knowledge that actually move you forward. Real investment in your learning.

• A front row seat while we build something big. We are building the financial operating system for European healthcare, with AI woven into how we build, sell and support. Real scope, real impact.

• Deutschlandticket or Swapfiets membership, so you get around the city fast.

• Urban Sports Club membership, for sport and balance.

• Flexible working hours and a hybrid setup.

• Up to 4 weeks of workation.

• A dog friendly office with great vibes and a team that is fun to work with.

We welcome applications from people of all genders and backgrounds, regardless of origin or age. If you're convinced you're the right fit for this role - even if your CV doesn't match the requirements 100% - tell us why.
