Trusted by Governments and world-leading pharma institutions and funded with $70m, we are on a mission to harness the power of connected data and bring precision medicine to life globally. The key to saving human lives is providing researchers across the globe with the right data to develop more precise drugs faster.\nGenerating large amounts of biomedical data has become relatively straightforward. The challenge now is finding, accessing and analysing this sensitive data stored across thousands of disconnected locations. It is frustrating and painfully difficult for researchers.\nLifebit has created a patented, federated technology that brings analysis and computation to where data resides. This enables researchers to run analyses on multiple, distributed datasets in-situ, avoiding the risky movement of highly-sensitive data.\nOur Federated AI Platform is trusted by federal agencies, national health systems, and global pharma to securely unlock sensitive biomedical and real-world data at scale. We help federal health institutions modernize data utilization and analytics in highly protected environments, supporting mission-critical federal programs and transforming how secure health data drives public health and research.\nOur technology is unmatched and momentum is on our side - and we need an exceptionally strong team to help boost Lifebit to incredible new heights.\nYour Impact\nAs an AI Engineer, you will be at the forefront of bridging the gap between massive, decentralized biomedical datasets and life-saving insights. You won't just be building \"standard\" models; you will be co-architecting AI that functions within a federated ecosystem, where privacy and security are paramount.\nYou will own the development and deployment of machine learning models-ranging from Large Language Models (LLMs) for clinical note extraction to predictive analytics for genomic research-ensuring they are optimized for our unique federated architecture. Your work will directly empower researchers to identify drug targets and disease biomarkers faster than ever before, transforming how the world approaches precision medicine.\nYour Role and Responsibilities\nAgentic Architecture & Orchestration\nDesign and implement autonomous AI agents using frameworks like LangGraph, CrewAI, or AutoGen to handle complex, multi-step scientific queries.\nDevelop sophisticated reasoning loops (e.g., ReAct, Plan-and-Execute) that allow agents to decompose high-level research goals into actionable sub-tasks.\nBuild and optimize Advanced RAG (Retrieval-Augmented Generation) pipelines that integrate structured clinical data and unstructured scientific literature.\nTool-Use & Execution\nCreate and maintain \"tools\" for AI agents, enabling them to safely interface with Lifebit’s federated APIs, SQL databases, and bioinformatic execution engines.\nImplement secure, sandboxed code-interpreter capabilities, allowing agents to write and execute Python or R code for data visualization and statistical analysis.\nFine-tune LLMs for specific function-calling and tool-use accuracy within the life sciences domain.\nSystem Reliability & Guardrails\nDevelop robust evaluation frameworks (LLM-as-a-judge) to measure agentic performance, truthfulness, and safety in a clinical context.\nImplement \"Human-in-the-loop\" (HITL) patterns to ensure high-stakes scientific decisions are always reviewed by domain experts.\nPartner with Security teams to ensure agents operate within strict data privacy boundaries, preventing prompt injection or unauthorized data egress in federated nodes.\nCollaboration & Scaling\nWork with Product and UX teams to design intuitive interfaces for interacting with agentic systems (e.g., conversational research assistants).\nScale agentic workloads in production using Kubernetes, ensuring low-latency reasoning and efficient token usage.\nRequirements\nEducation:BSc/MSc in Computer Science, Artificial Intelligence, Machine Learning, or a highly quantitative field (PhD preferred).\nExperience:2+ years of hands-on experience as an AI or ML Engineer, building a validated real product, ideally within a product-led biotech, health-tech, or SaaS company.\nTechnical Stack:Deep proficiency in Pythonand Typescript and standard ML frameworks (e.g., Langfuse, PyTorch, TensorFlow, JAX, Scikit-learn).\nNLP/LLM Expertise:Proven experience working with Large Language Models, including fine-tuning, and RAG (Retrieval-Augmented Generation) architectures.\nCloud & Infrastructure:Familiarity with AWS/Azure/GCP and experience deploying models in Docker/Kubernetesenvironments.\nDomain Knowledge:It is a plus to have experience working with biological, genomic, or clinical data is a significant advantage.\nAutonomy:A self-starter mindset with the ability to navigate ambiguity and drive AI projects from concept to production without constant oversight.\nWhat We Offer\nLifebit is synonymous with a dynamic work culture that encourages both personal and professional growth. Our mission-driven organization is dedicated to making a significant impact in science and healthcare.\nWe provide a comprehensive benefits package, including:\nCompensation: Your work is rewarded with a competitive salary and performance-based incentives.\nProfessional Development: You are granted an annual personal development budget of £1,000 and access to leading industry conferences, training, and certifications.\nFlexible Working: Receive 21-25 days of annual leave and fully remote work to maintain a healthy work-life balance.\nDiverse Team Culture: Join an international and diverse team passionate about transforming healthcare through data.\nDeep Technology & Science: Get exposure to problems and applications in the cloud, data analysis, ML, life sciences, and big data fields.\nJoin us at Lifebit for a career that promises to be your next significant venture, dedicated to advancing the scientific and healthcare fields by delivering transformative platforms for aging, defense health, and biomedical research.
