Senior Forward Deployed Software Engineer

We are looking for a Forward Deployed Software Engineer to help us solve complex workflow problems directly at the edge of our business: where product, engineering, commercial teams and customers meet.

What to expect in the role as Forward Deployed Software Engineer:

This isn't classic product engineering, nor pure implementation. You'll work alongside our Commercial teams and customers to find operational bottlenecks, then build pragmatic, high-quality software end to end: AI-powered workflows, internal tools, customer-specific automations, data migrations, dashboards and integrations that strip manual work out of onboarding and customer success.

Your role competency will sit in Engineering: we care deeply about technical quality, maintainability, security and ownership. Your business accountability will sit close to Commercial: your success will be measured by how much you unblock customers, reduce manual work and help Nelly scale faster.

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 isn't a nice-to-have 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:

• Work closely with Commercial, Product and Engineering to identify high-impact customer and workflow problems

• Build end-to-end solutions using TypeScript, React, AWS and modern AI/LLM tooling

• Own the problem from discovery to production: clarify the problem, design the solution, implement it, ship it, monitor it and improve it

• Be close to the customers: join customer conversations to understand workflows, validate assumptions, and translate real-world complexity into technical solutions

• Operate in ambiguous environments where there is no perfect spec, no perfectly prepared ticket and no one handing you a step-by-step plan

• Collaborate with Engineering to ensure your solutions meet our standards for reliability, security, observability and maintainability

What you'll bring:

• Several years as a software engineer, ideally from a startup or similarly fast, broad environment where you've worn many hats and owned things end to end - from understanding the user problem to shipping production-ready software

• Strong experience with TypeScript and React, and being comfortable working across the stack, including APIs and cloud infrastructure (ideally AWS)

• Hands-on experience building AI/LLM-based workflows and excitement about using them to solve practical business problems

• Strong curiosity about customer workflows and the ability to quickly understand operational complexity, even with ambiguity and incomplete information

• Pragmatism and strong product judgment: you know when to build something robust, when to automate, when to simplify, when not to over-engineer - and how to prioritise by business impact

• Strong communication skills with both technical and non-technical stakeholders

• Fluency in German and English

What we offer:

• Deutschlandticket (public transport pass covering all of Germany) 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's fun to work with

• Snacks and a fridge full of cold drinks

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.
