Senior Data Engineer - Data Platform team (100% Remote within Poland)

WELCOME TO THE GOOD SIDE OF TECH 👋 You might have heard about us, but with a different name: Znany Lekarz. It all started 12 years ago when we asked ourselves: is anyone in healthcare thinking about patients? We jumped in and we empowered patients by giving them access to leave and read reviews about their visit. We then provided doctors with the technology to manage bookings easily and save time, so they could devote themselves to what they always wanted: treating patients. And today is the day in which we ask you: wanna join us in the next step of making the healthcare experience more human? DOCPLANNER AT SCALE We are leaders in 13 countries so far, and more than 90 million patients trust us every month. 300k+ specialists believe in us and our product, and so do leading venture capital funds such as Point Nine Capital, Goldman Sachs Asset Management and One Peak Partners. And yet, employing over 2.500 people all over the globe, we managed to keep the startup mindset we started with over 10 years ago. At Docplanner, we are a diverse group of over 300 people working in Engineering, Data, and Product teams. We are responsible for building the product for all locations. Many of us have been here for over 5 years, yet we still welcome each new person with great joy and excitement. We could tell you about us, but we will let our reviews on Glassdoor https://www.glassdoor.es/Overview/Working-at-DocPlanner-EI_IE1071394.11,21.htm?countryRedirect=true speak for themselves. In case you’d like to see how it feels to be 100% yourself at work, here’s a video of us https://bit.ly/3xwnSAk. AND WHY SHOULD YOU JOIN US? Because it feels good to tell your family and your friends how you made the world a little bit better. You go to bed knowing that what you do matters, and that your talents align with your beliefs. We want to make the healthcare experience more human, and that starts with you being you. We believe that taking the diversity of human experience into account makes a better healthcare experience for all. We’re not just different: we embrace diversity. We will encourage you to come to work your whole self, and that includes not coming to the office at all if you prefer not to, as we're 100% remote-friendly. JOB DESCRIPTION At Docplanner, data is at the core of everything we do to make the healthcare experience more humane. Our Data Platform Team is the backbone for all things data: serving analysts, engineers, and product teams with robust infrastructure, high-quality data pipelines, and modern tooling. We’re looking for a Senior Data Engineer to join our team and support our growing platform operations. This is a role for someone who has already built and operated data platforms at scale, has strong opinions (loosely held) about how they should work, and wants to own problems end to end rather than tickets. WHAT THIS ROLE IS REALLY ABOUT You'll be a technical reference point in the team: designing and building the systems that ingest, transform, and serve data for the whole company — and raising the bar on how we do it. That means owning architecture decisions, driving them from proposal to production, and mentoring other engineers along the way. Our platform spans ingestion from dozens of heterogeneous sources, orchestration, a cloud data warehouse, transformation layers, and the infrastructure underneath it all. You won't just work on one slice: we expect seniors to be comfortable across the stack - from a dbt model that analysts depend on, to the Kubernetes workload that runs it, to the Terraform that provisions it, to the orchestration of all the pipelines involved. You'll go deeper in some areas than others, and we'll make sure your depth is put to good use. This is a hands-on engineering role with real ownership: you'll ship, operate what you ship, and shape the roadmap of the platform itself. WHAT YOU'LL BE DOING - Design, build, and operate scalable data ingestion and processing pipelines across many source systems - Lead…
