Senior Machine Learning Engineer

About the role

Portcast is a venture-backed, Singapore-based logistics technology startup helping freight forwarders turn data into better decisions and measurable business impact.

Portcast uses AI to surface shipment exceptions, cost risks, and the right actions, helping teams focus on the shipments that need their attention, keep freight costs under control, and make procurement decisions with confidence. Our vision is to be the AI data and intelligence layer that powers exception management and margin improvement on every shipment.

Founded in 2018 and backed by leading technology investors, we are building for an industry at a critical inflection point of digital transformation. Our team of software engineers, data scientists, and logistics experts is on a mission to build the technology that helps freight forwarders protect margin, improve operational efficiency, and differentiate their offering.

ABOUT THE ROLE:

We're looking for a Senior Machine Learning Engineer who owns solutions end to end, from framing the problem, to building and deploying the model, to running it in production. This is a hands-on, business-minded role in a lean team: you'll build ML and AI that drives real outcomes for our customers, and make pragmatic calls about cost, scale, and impact, not just model accuracy.

Our models (like predictive ETA) are one part of the picture, not the whole job. You'll own some products end to end and contribute to others, and you'll help decide what's worth building based on what moves the business. You'll work closely with our Data, Engineering, and Product teams, turning loosely defined problems, sometimes without clean baseline data, into shipped features. If you like figuring things out in ambiguity and seeing your work drive the business directly, rather than long research cycles in a big lab, you'll fit well here.

What You’ll Own: -

Own ML and AI solutions end to end: frame the problem, build the model, deploy it, and run it in production (MLOps). You own the full lifecycle, not just the modelling.

-

Own some products end to end and contribute to others, thinking about business outcomes, cost, and scale, and model performance.

-

Comfortable building from a rough outline rather than a finished spec. You'll work directly with product and customer-facing teams to turn loosely defined problems into shipped features, and re-scope quickly when priorities shift. You'll own the how, which means pushing back on a weak brief and making the call when the spec runs out. We have a strong sense of direction; the details pivot often.

-

Collaborate with Data, Engineering, and Product to understand the business goals behind what you are building, so what you ship actually moves the metrics that matter.

-

Build, test, deploy, and monitor real-time prediction models and ML algorithms that address the key business problems our product focuses on: visibility, prediction, demand forecasting, freight audit, using MLOps best practices with version control and performance tracking.
