Staff Machine Learning Engineer

The Company
We are a rapidly growing startup developing solutions that blend human expertise and AI agents to handle manual customer and marketplace operations tasks. Our approach combines the strengths of human expertise (high accuracy and nuanced decision-making) with the advantages of AI automation (speed and cost efficiency). This technology helps businesses solve real-world challenges in trust & safety and beyond without complex technical integration. We believe in an online world free from harm, where we can trust AI to make safe and fair decisions.

We have raised about $25M in VC funding from top-tier funds and operate at significant scale, analysing millions of daily images and videos. We are at the beginning of our journey and are excited about growth in the coming year and beyond.

The role

We are now looking for a Machine Learning Engineer to build and deliver innovative AI products to our customers. Your software expertise and machine learning knowledge will help transform our customers\' manual processes into AI-automated solutions. Your mission is to ensure our customers receive the most effective AI solutions for their specific needs, applying technical and analytical skills to understand customer challenges and collaborate to leverage our AI in automation. Initially, you will provide hands-on support for our machine learning models as they come to market, then gradually develop self-service tools that empower customers to achieve value independently.

As part of this role, you will:

• Collaborate with customers to thoroughly understand their workflows, then design and build AI agents that automate their processes
• Contribute to the development of our AI agent development platform that scales with our product strategy
• Ensure our AI services maintain high standards of reliability, observability, availability, and performance
• Participate in our machine learning community to influence how we implement machine learning and computer vision technologies
• Take ownership of customer outcomes with the autonomy to make decisions that delight customers
• Contribute full-stack development including software engineering, DevOps, and MLOps, along with light task and project management to ensure AI solutions deliver maximum value
