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.
You’ll help design:
- 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.
What You’ll Be Doing
- Designing end-to-end predictive pipelines (data → model → evaluation)
- 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
What We’re Looking For
- 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
Benefits
- Highly competitive salary
- Generous equity
- 35 days paid vacation
- Private healthcare
