Machine Learning Engineer

Machine Learning Engineer (L1)

Experience Required: 2-4 years

As a Machine Learning Engineer at Spring, you’ll help bring data-driven intelligence into our products and operations. You’ll support the development and deployment of models and pipelines that power smarter decisions, more personalized experiences, and scalable automation. This is an opportunity to build hands-on experience in real-world ML and AI systems while collaborating with experienced engineers and data scientists.

You’ll work on data processing, model training, and integration tasks — gaining exposure to the entire ML lifecycle, from experimentation to production deployment. You’ll learn how to balance model performance with system requirements, and how to structure your code for reliability, observability, and maintainability.

You’ll use modern ML/AI tools such as scikit-learn, HuggingFace, and LLM APIs — and be encouraged to explore AI techniques that improve our workflows or unlock new product value. You’ll also be expected to help build and support automated data pipelines, inference services, and validation tools as part of your contributions.

You’ll work closely with engineering, product, and business stakeholders to understand how models drive value. Over time, you’ll build the skills and judgment needed to identify impactful use cases, communicate technical trade-offs, and contribute to the broader evolution of ML at Spring.

What You’ll Do

Build and maintain automated pipelines for data processing, training, and inference.

Use ML and AI tools (e.g., scikit-learn, LLM APIs) in day-to-day development.

Collaborate with engineers, data scientists, and product teams to scope and deliver features.

Participate in code reviews, testing, and monitoring practices.

Integrate ML systems into customer-facing applications and internal tools.

Identify differences in data distribution that could affect model performance in real-world applications.

• Stay up to date with developments in the machine learning industry.
