Joining Our Mission

-----------------------

Shape the future. Make an impact.

At QuantSpark, pioneering the strategic application of data, analytics, and AI is at the heart of our work. We empower businesses and government to thrive, not just for profits, but for measurable human and societal benefit. This means tackling real-world challenges, innovating at scale, and forging solutions that leave a legacy of prosperity and efficiency.

Here, engineers and strategists collaborate daily, compressing years of traditional progression into an accelerated path. As a

Machine Learning / Applied AI Engineer

, you will design, build, and deploy intelligent solutions that bridge advanced machine learning and real-world product needs.


In this role, you'll develop reproducible training pipelines, evaluate and serve models through APIs, integrate open-source or pre-trained AI models, and ensure our AI applications are reliable, observable, and scalable in production.


You won't be doing research?grade AI -- you'll be turning proven models and techniques into real, shippable applications.
