Senior Machine Learning Engineer

Remote/Hybrid will be considered with frequent travel to the office

Vertex Search is proud to partner with a cutting‑edge, agile start‑up that has plans to double in size in 2026! They are already revenue‑generating and have created unique, bespoke AI solutions that produce double the accuracy of traditional LLMs.

As a Senior Machine Learning Engineer, you’ll sit at the intersection of machine learning, product, and engineering, working closely with a world‑class research team to turn advanced ML capabilities into a coherent, high‑impact agent used on real‑world problems. More specifically, you’ll build the intelligence layer of their highly advanced agentic AI agent.

• The iterative interaction between the Agent and users
• The ML logic and decision workflows powering the Agent
• Reusable predictive pipelines that generalise across datasets
• Robust evaluation and model comparison frameworks

This is a high‑ownership role where you’ll shape core product architecture in a fast‑moving environment.

• Implementing decision logic that guides and automates parts of the ML workflow
• Turning complex ML processes into reusable, scalable abstractions
• Integrating advanced research outputs into production workflows
• Writing clean, modular, production‑grade Python code
• Collaborating closely with research, product, and engineering

• Around 7+ years in ML Engineering or applied ML roles
• Strong experience building end‑to‑end ML systems used in production
• Deep expertise in working with agentic agents (experience in synthetic data, tabular data, or similar fields is a plus!)
• Excellent ML fundamentals and ability to reason about trade‑offs
• Strong Python and production‑quality coding practices
