Principal Machine Learning Engineer

TL;DR

machineMD is a Bern-based medical device company pioneering automated neurodiagnostics through our flagship neos™ device and oculometrics software. We’re hiring a Principal Machine Learning Engineer / Full-Stack Data Scientist to own end-to-end model development - from data pipelines and signal processing to scalable bayesian inference models - and help us bring specialist-level diagnostics into every clinic.

About machineMD

We’re on a mission to radically improve the measurement of brain function through standardized, automated, quantitative exams. Our signature product, neos™, is the world’s first non-invasive neurophtalmoscope for fast, automated assessment of eye movements and pupils. Founded at the University Hospital of Bern, Switzerland, we aim to bring the diagnostic quality of a highly trained tertiary-care specialist into secondary and primary care settings everywhere.

Tasks

As a Principal Machine Learning Engineer / Full-Stack Data Scientist at machineMD, you will:

• End-to-end ML - perform exploratory data analysis, design and implement ETL pipelines, craft signal-processing features, design and train models, and deploy them with robust monitoring.
• Research & Innovation - apply advanced FIR filtering, probabilistic modelling, non-linear correlation analyses and rigorous hypothesis testing to elevate diagnostic accuracy, while preserving full transparency and interpretability.
• Operationalization - optimize Docker images for minimal footprint, ensure Azure resources remain healthy and cost-efficient, and partner with software engineering to integrate new functionality into our product.
• Mentoring & Leadership - coach other engineers, uphold clean-code principles, and conduct systematic code reviews.

What We Look For

• Olympic-level Dedication - you sweat the edges of every algorithm and make it battle-ready for real-world data.
• End-to-end Ownership - you’re equally at home in a Jupyter/marimo notebook prototyping hierarchical bayesian models, as you are debugging ETL pipelines.
• Speed & Iteration - you ship prototypes quickly, get clinician feedback and pivot with agility to refine solutions.
• Technical Craft - you have strong opinions (and data to back them) on software engineering best practices, clean-code mantras and apply Nyquist-informed rigor to signal-processing challenges.
• Collaborative Spirit - you thrive in a flat, interdisciplinary team where decision rights are distributed and communication channels are short.

Requirements

• BSc, MSc, or PhD in Computer Science, Electrical Engineering, Data Science, Biomedical Engineering, or a closely related field from ETH, EPFL, FH or an equivalent institution.
• 7+ years of professional Python experience (incl. pandas and/or polars); bonus points for hands-on Rust or Julia.
• Demonstrated mastery of software development, signal processing, machine learning, and statistical methods; bonus points for hands-on experience applying GenAI techniques in production.
• Proven track record of shipping ML models in production (healthcare or other high-stakes domains).
• Fluent English; German and/or French a plus.

Benefits

Working at machineMD

Located in Bern, Switzerland, we thrive on collaborative, in-person energy, while offering the flexibility you need to do your best work.

We are united by the Four Pillars of Integrity: Radical Responsibility, Feeling Our Feelings, Candor and Clear Agreements. These are not just words on a wall; they guide how we:
