Applied AI Engineer

Job DescriptionJob DescriptionIterative Health is a healthcare technology and services company powering the acceleration of clinical research to transform patient outcomes.We built a leading performance-driven network of 100+ sites across the US, Europe, India, and Australia, conducting research directly in the communities where care is delivered across gastrointestinal, hepatology, obesity, and cardiology. By combining deep clinical trial expertise with cutting-edge AI, we connect sponsors' scientific ambitions with high-performing research teams that expedite and expand access to novel therapeutics for patients in need. Today, Iterative Health is headquartered in Cambridge, Massachusetts, and New York City with 250+ employees world-wide.We're looking for an Applied AI Engineer who can understand our data deeply enough to know what's possible, and turn that into working systems. We have a unique dataset within the industry — connecting clinical data (EMR, endoscopic video, etc.) to trial data across 80+ trial sites. The right person will dig into this data to understand its structure and gaps, build systems that translate that understanding into real outcomes for sites and patients, and bring a point of view on how new capabilities apply to our specific problems as the landscape evolves.You'll work hands-on with the data, build and ship models, LLM-based systems, and agents, and directly influence what we build and how. This role sits at the intersection of applied ML, engineering, and data science— you'll build the foundation for our predictive capabilities and help shape what that function becomes, on a small, fast-moving engineering team at a formative stage.Where You'll Drive ImpactWork with clinical, video, and clinical trial operational data to understand what's there, what's meaningful, and how to use it to drive a more efficient clinical trial systemBuild and ship ML models, LLM-powered systems, and agents — from prototype to productionStay close to the evolving AI and ML landscape and bring a point of view on how new capabilities apply to our data and problemsDefine the path from raw data to product and operationalization: what to model, how to evaluate it, and when it's ready to shipPartner with product and engineering to translate findings into shipped featuresIdentify opportunities where our data creates unique predictive advantagesEvaluate where we should build, where we should partner, and where existing approaches fall shortHelp shape the engineering culture of a small, growing team: how technical decisions get made, how problems get debated, and what rigor looks like in practicePerforms related duties as requested What You Bring to the Team5+ years of experience in applied AI/ML, software/ML engineering, or data science, with significant hands-on time building and shipping systems on real dataExperience with healthcare data, clinical research, or life sciencesDeep curiosity to understand data and connect it to the real worldStrong statistical foundations and the judgment to know when a result is meaningful versus interestingFluent in Python and SQL, comfortable across the data stack from exploratory analysis through production-ready code and pipelinesExperience working across data science, product, and engineering — able to build what's needed, not just analyze what existsExperience building and shipping production systems — including LLM-powered features (prompting, evaluation, RAG/agent pipelines) — not just research code or notebooksExperience with complex, messy, real-world data and how to make it useful without pretending it's cleanKnowledgeable about ML capabilities and frameworks, with the judgment to know when something is genuinely applicable versus hypeStrong communication skills — able to convey findings clearly to technical and non-technical audiences and make a persuasive case for what to build nextPreferred QualificationsExperience working at growth-stage startups (strongly preferred)Experience with LLM application frameworks (e.g. RAG, agent orchestration, eval harnesses)Familiarity with clinical trial operations, disease classification, or patient identification problemsExperience building or defining the roadmap for an AI function from early stages How We WorkCollaborative and low-ego team environmentHigh ownership and accountability cultureFast-paced and highly iterative growth environmentOpen communication and continuous learning mindsetMission-driven organization focused on improving patient outcomesComfortable navigating evolving business priorities and opportunities Benefits That Support YouWe believe great teams do their best work when they feel supported — professionally and personally.Hybrid work environment with in-office collaboration two days per week in either our NYC, Southlake or Boston officeComprehensive medical, dental, and vision coverage, with up to 80% of premiums covered by Iterative HealthMental health and wellness support through Spring HealthHealth HSA or FSA options, and commuter FSA contributions supported by Iterative HealthUnlimited PTO, 12 company holidays, and a company-wide shutdown between Christmas and New Years401(k) program with a company match of up to 3% (up to $3,000 annually)Weekly in-office lunch benefit every Tuesday100% company-paid short-term and long-term disability coverageAnnual wellness and professional development stipend to support your health and growthAnd more!
