This job is brought to you by Jobs/Redefined, the UK's leading over-50s age inclusive jobs board.

Overview

Unitary's purpose is to make the internet safer in order to improve lives and create a fairer world. We are a rapidly growing start-up developing solutions that blend human expertise and AI agents to handle manual customer and marketplace operations tasks. Our unique approach combines the strengths of human expertise (high accuracy and nuanced decision-making) with the advantages of AI automation (speed and cost efficiency). This cutting-edge 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, including Creandum and Plural, and operate at a significant scale - analysing millions of images and videos daily from the world's largest platforms. But we are just at the beginning of our journey - and we are very excited about our plans for growth over the coming year and beyond!

Role

The company

Senior/Staff Engineer

The role reports to a Staff Engineer and can be based in the UK or anywhere within 3 hours of the UK timezone.

Responsibilities

• Re-imagine and refactor our existing services and tooling. Our current toolset has helped us grow from 0 to approximately 10 clients in the past 8 months. We need them to scale beyond this point by re-imagining them into robust capabilities that match our growth, guided by learnings from pathfinder clients.
• Deliver software as part of onboarding new clients and use cases. Work in a customer-focused team alongside Machine Learning Engineers who are developing the Agent AI needed to operate client processes.
• Establish design patterns and approaches that others can follow. Set design patterns befitting our evolving business proposition and enable lean architecture governance.
• Bridge our Machine Learning and Platform Engineering capabilities. Act as software glue to bring together our ML/MLOps engineers and platform engineers.
• Contribute to a new generation of tools and services for building AI Agents to support growth to 30+ clients.
