Founding ML Engineer

About the Company

Philyron is building the predictive brain for commercial fleets from tankers, cargo ships to defense vessels. We use real-time sensor data and historical maintenance records to predict and explain engine failures before they happen.

The Role

We're hiring a founding ML engineer to own the AI systems at the heart of the product. You'll work directly with the founders and own the full loop: data, training, evals, and shipping models into production.

What You'll Do

• Connectivity — get data off the ship. Ships have terrible, intermittent connectivity. You'll build the pipeline that moves sensor data from a vessel's edge device to our cloud reliably over satellite links (VSAT / Starlink) — using lightweight, fault-tolerant protocols (MQTT / Sparkplug B), with encryption in transit and graceful handling of connections that drop for days at a time and resume.

  Cloud backbone — land it and make it usable. You'll stand up our cloud architecture (AWS): a real-time "hot path" that checks incoming sensor metrics against safety thresholds and fires instant alerts, and a "cold path" that stores high-frequency time-series data for trend analysis and model training. You'll also build the integration layer that pulls decades of historical maintenance records out of operators' existing CMMS databases — the data that makes our predictions possible.

  Predictive fusion engine — the reason we win. This is the heart of it. You'll build the ML system that fuses two data streams almost no competitor combines: live sensor signatures and historical failure records. You'll map past maintenance events to the sensor patterns that preceded them, train anomaly-detection and failure-prediction models (e.g. isolation forests / autoencoders for anomalies, gradient-boosted trees / LSTMs for remaining-useful-life), and design the fleet-wide-plus-per-vessel modeling approach that makes predictions both accurate and personalized to each engine. The output isn't "anomaly detected" — it's "this pattern preceded a gearbox bearing failure across the fleet; inspect within 14 days."

  Automated reporting. You'll build the service that compiles trends, history, and predictions into clean reports delivered to operators on a schedule — turning the platform into something that shows up in their inbox and proves its value every week.

What We're Looking For

• Evidence you've shipped ML that real users touched - in production, research, or serious projects

• Show us projects, repos, demos, side projects — real things you've designed and built end to end, ideally ones that touched both data/ML and the infrastructure around it. Your portfolio is your résumé.

• Strong fundamentals across the stack, not just notebooks

• Pragmatism: you pick the boring approach that works over the clever one that might

• Comfort owning systems end to end with no ML team behind you
