We value diversity and encourage individuals of all genders to apply.

As Head of Engineering for our Unified Data Platform, you will lead one of our most strategically important domains. Your teams own the core systems that integrate with external practice management systems, harmonize data and provide the scalable foundation that powers our AI products.

This domain is both high-impact and technically challenging. We integrate with many different customer environments, operate in both cloud and on-premise setups, and handle data that must be accurate, consistent and available at all times.

Reporting directly to the CTO, this role has significant visibility and influence. You will help define how we scale our platform, teams, and ultimately the business.

About Nelly

We are a Tech Company and we believe healthcare should feel a lot less like paperwork… and a lot more like people. So we’re building the technology that lets medical practices run smoothly, simply, and without all the admin chaos that slows everyone down.

Our platform turns messy processes into smart, automated workflows, from patient journeys to billing to next-generation payments. Powered by AI, built for real humans, and designed to give medical teams the time and headspace they desperately need.

Why? Because Europe is facing a massive shortage of medical assistants. And if we don’t rethink how practices operate, the system won’t be able to keep up. We’re here to fix that, not with band-aids, but with real transformation.

We’re backed by €50M in Series B funding from world-class investors and are scaling fast to build Europe’s leading healthcare fintech. Our vision: empower over a million medical practices and make life better for millions of patients.

But here's the part we’re proudest of: we only work with nice people. It’s our number-one rule. No egos, no drama, no jerks. Just kind, curious, hardworking humans building something meaningful together.

If that sounds like your kind of place — welcome to Nelly.

Own and scale the engineering teams for Integrations, Data Platform, and Infrastructure - the mission critical data platform at the core of our business and the user workflows.

Partner closely with product and business stakeholders to define business and technical strategy, drive clear priorities and technical decisions that create measurable business outcomes.

Develop a technical strategy for the domain that empowers teams to self-serve, while framing technical decisions through business outcomes such as revenue impact, time saved, and risk reduction.

Own the integrations strategy and delivery (build vs. deepen vs. partner), improving ICP PMS coverage, read/write depth, and SLO-backed reliability while reducing activation time.

Operate at every altitude, step in hands-on when needed to unblock teams or clarify complex technical decisions.

Build, grow, and drive cultural change for high velocity engineering teams while raising the performance bar.

Manage and mentor multiple Engineering Managers and their teams by providing structure, direction, and coaching at scale.

Represent the domain together with your product counterpart and drive cross-functional alignment within the organization.

Attract senior talent and hire across profiles (backend, data, infra/SRE, AI tools, EM).

Report directly to the CTO and play a major role in shaping Nelly’s long-term engineering strategy.

10+ years of experience in engineering, including 5+ years in leadership roles managing managers or multiple teams.

A proven track record of building and leading high-velocity, cross-functional engineering teams in fast-paced or high-growth environments.

Built complex data systems that integrate with multiple external data sources (read & write) (e.g. practice management systems) to leverage that for scaled AI and end user facing applications.

Strong track record building integration-heavy platforms: bidirectional connectors (read/write), canonical models, data contracts, and SLO-driven operations—including hybrid cloud/on-prem constraints and high reliability requirements.

Experience shipping and operating multiple third-party integrations at scale, including quality/testing strategies (read-after-write, reconciliation, regression suites) and operational tooling.

Curious, ambitious and experimental mindset: you challenge existing assumptions and bring new perspectives on data, AI-driven architectures, and modern engineering practices. Innovation and insights first, while keeping in mind the complexity of the domain. Familiarity with cloud architecture (AWS preferred) and modern engineering toolchains.

Excellent communication skills, able to explain complex technical systems simply to non-technical stakeholders, able to voice opinions, disagree and commit.
