Data Engineer

MISSION Neko is redefining what prevention means, from treating illness when it arrives, to sustaining health before it's ever at risk. Our mission: make data-driven, preventative care accessible to more people, before symptoms appear. In a single, non-invasive visit under an hour, proprietary technology and direct clinical care combine to deliver personalised, actionable insights. It's a team that thinks in 10x, not 10%. Every role here plays a part in building a world where prevention is the norm, and where your work genuinely helps people live longer, healthier lives. ROLE PURPOSE As a Data Engineer within our Data-to-AI platform, you will play a critical role in enabling healthcare innovation through robust, scalable, and secure data systems. You will design and build core data platform components, advanced data models, and ingestion frameworks that power analytics, machine learning, and data-driven decision making across the organization. Working with sensitive healthcare data, you will ensure strong governance, data quality, and regulatory compliance remain foundational to the platform. WHAT YOU’LL DELIVER IN THE FIRST 6–12 MONTHS • Build and productionize scalable batch and streaming data pipelines supporting platform and research workloads. • Design and implement robust data models across databases and lakehouse systems to support analytics and machine learning. • Establish strong data quality, monitoring, and lineage practices improving reliability, traceability, and trust in platform data. • Contribute to scalable and well-governed data platform infrastructure supporting performance, compliance, and growth. • Partner closely with data scientists, analysts, and engineering teams to enable reliable data contracts and high-quality datasets. RESPONSIBILITIES • Build and own scalable data pipelines for ingestion, integration, and processing across batch and streaming systems. • Architect and maintain robust data models across databases and lakehouse platforms supporting analytics and ML workloads. • Develop and own core data platform components and infrastructure. • Ensure data integrity and quality through monitoring, alerting, lineage, and traceability. • Manage and optimize data infrastructure including clusters, storage, and compute resources. • Implement metrics and observability across services using logging, tracing, and monitoring. • Troubleshoot production issues, pipeline failures, and performance bottlenecks. • Collaborate cross-functionally with data scientists, analysts, and backend engineers on modelling, governance, and integration. MINIMUM QUALIFICATIONS • Strong programming skills in Python and SQL. • Hands-on experience with relational and NoSQL databases, data lakes, and lakehouse technologies (e.g. Delta Lake, Parquet). • Experience working with cloud infrastructure (Azure, AWS, or GCP). • Familiarity with CI/CD pipelines and automated testing practices. • Strong data quality and observability experience including metrics, tracing, and alerting. • Experience working with data governance practices including lineage, cataloguing, access control, data contracts, and regulatory compliance. ABOUT THE ENGINEERING TEAM Neko Health has nearly 100 full-time engineers working across Berlin, Chamonix, Hamburg, Lisbon, Marseille, Vilnius, and Stockholm, spanning disciplines such as Hardware Engineering, Firmware Development, Electrical Design, Algorithm Development, Machine Learning, Optronics Research, and Software Engineering. Our technology stack includes React, TypeScript, C++, Python, and C# with ASP.NET http://ASP.NET Core. We use Azure Cosmos DB and Azure Active Directory for authentication. We are a Remote-First company, though some hardware and firmware roles require occasional access to physical devices. Software engineers in Stockholm typically work from the office once every one to two weeks. Teams meet in person several times per year for collaboration and team connection. ORGANIZATION AND WAY OF WORKING Engineering teams are structured into small, cross-functional groups aligned to specific goals. Some teams are long-lived while others are created for targeted initiatives. Teams aim to operate autonomously while collaborating across the organization when necessary. Goals are tracked quarterly and annually, with bi-weekly organization-wide progress reviews. Most teams operate on a bi-weekly planning cadence, though each group has flexibility in how they work. All teams present progress, learnings, and experiments during bi-weekly engineering demos, covering topics ranging from hardware and calibration challenges to infrastructure improvements, backend capabilities, and data innovations that enhance clinical productivity. Neko Health supports a flexible workplace that prioritizes work-life balance. We are deeply committed to our mission while believing meaningful impact should not require sacrificing personal wellbeing.
