Machine Learning Platform Engineer

Machine Learning Engineer (Infrastructure Focus)

We are seeking a Machine Learning Engineer (Infrastructure Focus) to strengthen and streamline our ML and Bayesian Optimization (BO) package development. This role focuses on testing, reproducibility, and code reliability — building the systems that make our ML research fast, traceable, and production-ready.

This position is ideal for a strong Python engineer who enjoys designing robust, maintainable ML workflows and collaborating across data science, MLOps, and software teams.

Core Responsibilities:

• Architect the next generation of Sunthetics's optimization engine — enhancing reliability, modularity, and adaptability for new modeling features and experimental configurations.
• Implement experiment tracking and model versioning (e.g., MLflow, DVC, internal tracking systems).
• Build automated validation and testing frameworks for model inputs, outputs, and optimization routines using Pytest, Pydantic, and continuous integration tools.
• Collaborate with ML to productionize new Bayesian Optimization and Active Learning methods.
• Maintain connector layers between ML modules and the software platform (API-level integrations).
• Partner with MLOps and backend teams to improve deployment and inference pipelines, ensuring reproducible ML behavior across environments.
• Champion software engineering best practices — code modularity, version control hygiene, testing coverage, and CI/CD for ML.

Ideal Profile:

• Bachelor's or Master's degree in Computer Science, Data Science, Applied Math, or related field.
• 3+ years of experience in ML or backend software engineering.
• Strong Python engineering background, including experience with Pytest, Pydantic, and modular package design.
• Hands-on experience with ML frameworks (especially PyTorch, Botorch, Optuna, or MLflow).
• Demonstrated ability to transform research prototypes into maintainable, production-ready modules.
• Passion for testing, maintainability, and reproducibility as first-class ML engineering priorities.

Why This Role Matters:

This position directly supports Sunthetics' goal of building scalable, reproducible ML infrastructure. You'll enable the ML team to deliver new features faster, reduce refactoring overhead, and maintain reliability across client campaigns and product development.

Your work will:

• Accelerate the release of new ML and optimization features.
• Multiply the impact of the core ML team by transforming ad-hoc workflows into sustainable, automated systems — freeing researchers to focus on innovation, not infrastructure.
• Build the foundation for sustainable scaling of Sunthetics ML.

What We Value:

• Clean, maintainable code over clever hacks.
• Cross-functional collaboration — you'll work closely with data scientists, MLOps, and product teams.
• Ownership and autonomy — ability to design, document, and deliver robust systems independently.
• Sustainability through engineering — building tools that make science faster, cleaner, and more efficient.

Salary and Benefits:

• Competitive salary and company equity package.
• Health benefits.
• Opportunities for internal promotion.
• Small-team setting with a collaborative atmosphere.
• Fully remote team.
