Jobs, fresher vacancy - Machine Learning Research Engineer • UK

Company: Unitary

UK

The companyWe are a rapidly growing startup developing solutions that utilise Virtual Agents to handle manual customer and marketplace operations tasks. Virtual agents blend deterministic Python code, LLM reasoning and agentic AI capabilities to undertake this work, along with a fallback to human experts.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 the need for 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 significant scale - analysing millions of daily images and videos from 10+ Enterprise customers. 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!The roleWe are now looking for a Machine Learning Research Engineer to help build and deliver a platform that can automatically create Virtual Agents for operational processes currently undertaken manually using browser-based UIs. An important part of our offering is the ability to interact with a customer’s existing tooling, and we have found encoding repetitive interactions as Python code to be a powerful strategy. We envision the need for an “Agent Factory” that can compile the deterministic portions of workflows into reliable, testable code. This “Agent Factory” will learn from captured demonstrations of workflows and transform our customers' manual processes into automated solutions that combine the speed and reliability of code with the power of AI, where reasoning is needed.Your mission will be to create capabilities that automate the creation and management of Virtual Agents.You will use your knowledge of Agentic approaches for code generation and software engineering best practices to design and develop these capabilities - leveraging state-of-the-art LLM coding frameworks and endowing them with the tools and guardrails needed to reliably build and test automated workflows. You will work with customer-facing technical teams to configure and deploy the Virtual Agents for customer work.You will push the boundaries of Agentic automation, leveraging the best-in-class capabilities where it’s appropriate and developing in-house when we need to.You will work with platform and software engineers to turn these capabilities into robust operational systems that can scale to deliver Virtual Agents to most operational processes currently undertaken by humans.As part of this role, you will:Design and build capabilities that create Virtual Agents - an “Agent Factory”Robustly evaluate the agent creation process, allowing a systematic improvement in capabilities through experimentation against benchmarksImplement code generation capabilities, guardrails and evaluations, specialised for encoding workflows based on customer documentation and input, such as captured browser demonstrationsDrive the uptake of these capabilities with our customer-facing technical teamsUtilise best-in-class capabilities to deliver these capabilitiesResearch, invent and create novel capabilities where gaps in industry require itParticipate in our machine learning community to influence how we implement machine learning and computer vision technologies, shaping Unitary's future.Contribute full-stack development, including software engineering, DevOps, and MLOps, along with light task and project management to ensure your capabilities deliver maximum value early.RequirementsYouWe are looking for someone as excited about Unitary’s mission as we are, who wants to have a large impact at an early-stage startup, and be a key part of defining Unitary’s future as one of our early employees. We need versatile people who are happy to get stuck into whatever needs doing, and are ready to learn and grow with the company.For this particular role, we need a proactive AI and machine learning expert who is familiar with leveraging and creating AI capabilities and who is comfortable engaging with customers and exploring and presenting new ideas. Strong communication skills are essential, as you'll liaise with a range of technical, product and executive stakeholders throughout.We would love to hear from you if you:Know how to create systems for Agentic development, including mechanisms to guide and enhance state-of-the-art LLMsHave expert knowledge of the capabilities of Agentic AI and Generative AICan assess where best-in-class industry capabilities can help us undertake operational workflowsKnow how to invent novel capabilities based on rapid research iterationsCan work with other engineers to understand and solve challengesHave strong Python and engineering skillsCan demonstrate problem-solving and project management skills to analyse workflows and design automated solutionsThrive in a collaborative environment where group output and team achievements weigh heavily than individual inputCan travel to our company-wide off-sites three times per yearIt would be even better, but not essential, if you have:Experience working in a fully remote, international teamExperience with Temporal or similar workflow orchestration platformsPrevious startup experienceExperience with MLOps practices and tools, and monitoring machine learning systems in productionKnowledge of browser-based automation methods, such as playwrightKnowledge of CI/CD practices and tools such as GitLab CI, Argo CDProficiency with SQL and NoSQL databasesWorked with Kubernetes and infrastructure as code (IaC) tools such as TerraformThis role will report to the Chief Scientist and can be placed anywhere within 3 hours of the UK time zone.BenefitsThe teamUnitary is a remote-first team of c. 20 people spread across Europe and North America who are fiercely passionate about making the internet a safer place, and deeply motivated to become a force for good.
