Staff AI Engineer

Join the Team Modernizing MedicineAt ModMed, we’re not just building software—we’re reimagining the healthcare experience. Founded in 2010 by a practicing physician and a successful tech entrepreneur, we took a radically different approach: we hired doctors and taught them how to code. This "for doctors, by doctors" philosophy has allowed us to create an AI-enabled, specialty-specific cloud platform that places patients at the center of care.A Culture of ExcellenceWhen you join ModMed, you’re joining an award-winning team recognized for innovation and employee satisfaction. From our global headquarters in Boca Raton Florida, and extensive employee base in Hyderabad India, we are a team of 4,500+ passionate problem-solvers on a mission to increase medical practice success and improve patient outcomes: Consistently ranked as a Top Place to Work 2025 Globee Business Awards: Gold Globee for “Technology Team of the Year” 2025 Black Book Awards: Ranked #1 EHR in 11 Specialties Florida Venture Forum: Venture-Backed Company of the YearWe are growing fast, thinking big, and we are just getting started.Ready to modernize medicine with us? Job Description Summary:As a Staff AI Engineer, you define and drive the architecture of AI and agentic systems across multiple teams and product domains. This is a senior individual-contributor leadership role: you influence high-impact architectural decisions, evolve the practices and standards for building agentic AI, and turn experimental AI capabilities into reliable production systems. You set direction for multi-agent orchestration, production RAG (hybrid search, re-ranking, and query routing), tool and MCP integration, and the evaluation and observability stack that keeps them dependable. You mentor senior engineers and represent AI engineering in cross-functional and strategic initiatives. A background in classical ML is an asset; the primary requirement is a proven track record of shipping production agentic AI.KEY RESPONSIBILITIESDefine and drive technical direction for AI and agentic systems, and contribute to the AI platform roadmap across teamsInfluence architecture decisions for compute, cloud, and AI infrastructure across teamsLead the design of large-scale AI/LLM systems: inference platforms, APIs, and distributed architecturesArchitect production multi-agent systems end-to-end: orchestration, state management, tool integration, and failure handlingDefine and drive best practices and standards for AI/LLM systems across teams (agent design, evaluation, observability, reliability)Lead complex production debugging and incident response across teams, and harden the resulting fixes into platform guardrailsMentor senior engineers and emerging technical leaders, raising the engineering barLead technical design reviews and architecture decision records (ADRs) for critical AI infrastructureContribute to capacity planning and cost optimization strategies for AI/LLM infrastructureGENAI / AGENTIC AI CAPABILITIESDefine and drive vector database and RAG architecture decisions across systems and teams: structured RAG, hybrid search (dense + sparse + keyword), re-ranking, and query routingLead multi-agent platform architecture decisions: runtime selection, orchestration patterns, and enterprise integration strategySet the technical direction for MCP (Model Context Protocol) adoption and agent runtime infrastructureShape agent infrastructure adoption: evaluate and standardize frameworks, tooling, and deployment patterns for agentic AIArchitect evaluation infrastructure for non-deterministic LLM systems: synthetic golden-set generation, hierarchical weighted scoring (component, composite, and system-level F1), bootstrap confidence intervals, and paired A/B comparison, treating a change as real only when it is both statistically significant and clears a minimum effect sizeGate deployments on eval results: tiered regression thresholds (hard-gate vs monitor components) wired into CI so a measurable quality regression blocks the release, with observability via tracing across multi-step chains and tool calls and drift detection on LLM inputs and outputsDrive LLM cost optimization at scale: model routing, caching, batching, token budget management, and provider cost analysisREQUIRED SKILLS & QUALIFICATIONSMaster’s or Ph.D. degree in Computer Science, Software Engineering, or a related field.10+ years of professional experience in ML/AI or software engineering, including 4+ years in senior or staff-level roles with production system ownershipDemonstrated engineering leadership, including driving technical strategy and influencing cross-team decisionsExpertise in platform and distributed-systems architecture at scale: model serving, APIs, data platforms, and AI/LLM infrastructureHands-on experience architecting and operating production agentic AI or LLM systems (multi-agent workflows, production RAG, tool and MCP integration)Deep understanding of embedding models, retrieval algorithms, and vector database internalsStrong production debugging, reliability, and incident-response skillsExperience building rigorous evaluation for non-deterministic AI systems, including statistical methods (such as bootstrap confidence intervals and minimum effect-size thresholds) to separate genuine quality changes from run-to-run model varianceCost-awareness for cloud AI/LLM workloads: capacity planning and cost optimizationProven mentorship of mid-level and senior engineersStrong communication skills for executive and cross-functional audiencesPREFERRED QUALIFICATIONS (NICE TO HAVE)Experience in Healthcare, FinTech, or other regulated industriesExperience building AI/LLM systems or platform components from the ground upDefined best practices for AI-assisted development (Claude Code): code quality standards, review, and responsible usage across teamsTrack record of conference talks, published papers, or significant open-source contributionsExperience with GPU-accelerated inference and model serving optimizationFamiliarity with workflow orchestration and streaming architectures for real-time AIModMed Benefits Highlight: At ModMed, we believe it’s important to offer a competitive benefits package designed to meet the diverse needs of our growing workforce.

The imposters are creating misleading email accounts, conducting remote "interviews," and making fake job offers in order to collect personal and financial information from unsuspecting individuals. Please be aware that no job offers will be made from ModMed without a formal interview process, and valid communications from our hiring team will come from our employees with a ModMed email address (View email address on click.appcast.io). Please check senders’ email addresses carefully. Additionally, ModMed will not ask you to purchase equipment or supplies as part of your onboarding process.
