Head of Engineering and ML

Head of Engineering & ML — Syn Syn delivers real-time chemical analysis of food and other products using near-infrared spectroscopy, and we're building toward a broader vision: industrial intelligence that combines spectral data with customer process data (LIMS, ERP, MES, SCADA) to model and optimize production. We've captured over 2 million spectra to date — a rare dataset we're ready to put to work. We're looking for a hands-on technical leader to take ownership of our engineering roadmap and lead our next phase: migrating from a Java monolith to a modern, web-based microservices architecture, while pushing our modeling capability from classical chemometrics into deep learning. What you'll do - Own the engineering roadmap, day-to-day development management, and delivery timelines - Lead and grow a team of 2 engineers - Drive the migration from of key infra from monolith to a microservices, web and API-first architecture (ongoing) - Build the tooling that lets our customer success team train and retrain spectral models (PLS, PCA) with minimal effort - Lead R&D into deep learning architectures for spectral data, and process modeling for industrial intelligence What we're looking for - 6–10 years of experience across software engineering and machine learning, ready to lead - Strong software architecture judgment, especially monolith-to-microservices and API-first design - Hands-on experience with PLS/PCA and a strong interest in deep learning for spectral or signal data - Hands-on expertise with Microsoft Azure (we're part of the Microsoft for Startups program) - Entrepreneurial mindset and appetite for ownership - Based in Madrid preferred — we're a close-knit team and believe working together in person helps us move faster What we offer Ownership of a live, revenue-generating platform's technical direction, leadership of a growing team, and competitive compensation with equity.
