Senior Software Engineer - HLS

Life at UiPathThe people at UiPath believe in the transformative power of automation to change how the world works. We’re committed to creating category-leading enterprise software that unleashes that power.To make that happen, we need people who are curious, self-propelled, generous, and genuine. People who love being part of a fast-moving, fast-thinking growth company. And people who care—about each other, about UiPath, and about our larger purpose.Could that be you?About the RoleJoin the HLS team and help build UiPath's most ambitious product - an AI agentic orchestration platform that's been recognized as our Invention of the Year for two consecutive years. As a Senior Software Engineer, you'll be at the forefront of our Act 2 strategy, building the infrastructure that allows enterprises to seamlessly orchestrate AI agents, robots, and human-in-the-loop workflows to achieve critical business outcomes.What You'll DoBuild and Scale: Design, develop, and maintain backend services for HLS products using AI Coding Assistant for building distributed systemsHands-On Development: Write production-quality code daily, leveraging AI tools (Claude, GitHub Copilot, etc.) to enhance your development workflowPrototype and Ship: Take ideas from concept to working demo in days, validate with real customers, and turn the ones that prove value into production systems. Measure what matters: Design evaluations, measure quality against real customer data, and understand when metrics mislead. Our systems are often non-deterministic. Responsible shipping means measuring honestly, not chasing vanity numbers.Customer-Centric Engineering: Deeply understand who will use the features you build and why they need them, translating customer needs into elegant technical solutionsEnsure Reliability: Contribute to building highly scalable, reliable distributed systems that enterprises depend onOn-Call Rotation: Participate in on-call rotation (approximately one week every 2-3 months) to ensure system reliabilityWhat We're Looking For:Required QualificationsBuilder mindset — you enjoy turning ideas into working systems and taking ownership from concept through productionStrong backend engineering in Python and/or C# — most HLS product development is Python (agents, APIs, ETL), while core platform work includes C#. Willingness to work across both is important.Experience building production AI systems — LLMs, tool-calling, structured outputs, orchestration, and evaluation of model behavior in real-world workflowsExperience with agentic or workflow-based systems — multi-agent architectures, orchestration frameworks (LangGraph, LangChain, or equivalent), durable workflows, retries, and long-running execution patterns Experience with healthcare systems or standards such as Epic, Cerner, X12 EDI (835/837), CARC/RARC denials, HL7/FHIR, ICD-10/HCPCS, prior authorization, claims, or revenue cycle workflowsComfortable working with non-deterministic systems — debugging failures, evaluating quality empirically, and distinguishing between model, prompt, and data issuesDistributed systems experience — designing resilient systems with idempotency, replayability, state management, and long-running jobsStrong analytical thinking — able to reason quantitatively about system quality and make sound decisions using imperfect signalsComfortable with ambiguity and rapid prototyping — able to move from idea to proof-of-concept quickly and iterate based on customer feedbackHealthcare domain experienceNice to HaveData science and evaluationExperience with applied ML techniques such as classification, anomaly detection, ranking, or predictive modelingExperience evaluating AI systems using experimentation, metrics, and empirical analysis to improve quality and reliabilityData and retrieval systemsExperience with large-scale data platforms (Snowflake, columnar warehouses, denormalized data models) Familiarity with retrieval-heavy architectures, RAG systems, or citation-grounded AI workflows Engineering for trustworthy AIExperience blending deterministic and probabilistic systems (rules engines + AI)Experience designing eval-driven systems, regression testing for LLM outputs, or human-in-the-loop review workflows PHI/HIPAA-aware engineering and multi-tenant system design Platform and product developmentFrontend familiarity (React, TypeScript) Workflow orchestration platforms (Temporal, Airflow, Maestro, BPMN, Step Functions)Kubernetes and distributed infrastructure Experience in startups, applied research, or 01 product environments Open-source contributionsHow We WorkHLS operates like an internal startup inside UiPath: small teams, fast iteration, and real customers in the loop. We build quickly, test ideas with users, and turn the best ones into products. Some ideas won’t make it — that’s expected. You’ll work in short cycles, demo frequently, and adapt as we learn. We care more about solving the right problem than protecting a plan that no longer fits. If you enjoy ambiguity, rapid feedback, and building where product boundaries move fast, you’ll likely thrive here.About the TeamYou'll be working with Lax and the Maestro backend team to build the core orchestration engine that powers enterprise AI automation.
