healf - Founding Head of Engineering - Healf Zone

• A rare combination: an exceptional engineer with a real founder's instinct. • Founder Mentality • You want to go all-in. You're looking for the thing you'll pour yourself into, your best work, not another job. • You're energised by ambiguity and a blank page - you'd rather define the path than be handed it. • You have extremely high-agency and want to move with speed • Proven 0-to-1 experience: you have built meaningful products or platforms from scratch rather than inheriting established systems. • Technical Excellence: • 7+ years of experience designing and building complex, data-driven products at production scale. • Excellent Python backend engineering skills. • Experience with Next.js or an equivalent modern frontend framework. • A strong understanding of distributed systems, data pipelines, and scalable architecture. • Technical leadership experience, including setting direction and guiding engineers across multiple teams or workstreams. • Experience working with health, wearable, sensor, clinical, or recommendation data is highly valuable. • Experience building products in digital health, diagnostics, wellness, fitness technology, or another data-rich consumer environment. • Familiarity with wearable, sensor, lab, biomarker, or other longitudinal health data. • Experience designing systems such as sensor ingestion pipelines, data-fusion layers, knowledge graphs, scoring engines, or rules-based protocol systems. • Exposure to clinical data models, health ontologies, or decision-support products. • Familiarity with machine learning systems and how to integrate model outputs into production products, although the Platform team owns the core ML layer. • Experience working with privacy-sensitive or regulated data, including consent, security, governance, and data-quality considerations. • Competitive and meaningful compensation package for the right person. We ask a great deal of the people who work here. We expect full ownership and a genuine commitment to give this chapter everything you have. • In return, we will give you the same: everything we have, invested in your growth, your wellbeing, and the defining skills of the next decade. • We have built the fastest-growing company in Europe with a team small enough that every person in it shapes the outcome. That is still true today. The next person we hire will change the trajectory of the company. • IF THE MOST IMPORTANT WORK OF YOUR CAREER IS AHEAD OF YOU, THIS IS THE PLACE TO DO IT.
