Job Description

Our generative AI-powered products are making a huge impact in the Healthcare industry. As an AI Platform Engineer, you will collaborate closely with a cross-functional team of researchers, clinical scientists, and product engineers. You will design and build the runtime, orchestration engine, and evaluation platform for agentic orchestration and LLM-driven workflows.

Job Responsibility

  • Design and build GenAI systems that turn LLMs into composable, dependable tools—leveraging retrieval, tool use, agentic reasoning, and structured outputs
  • Design and implement a highly reliable and scalable agent runtime: orchestration, shared state and memory, tool-calling interfaces, and scheduling for cost, latency, and quality
  • Build secure, sandboxed execution for agent actions and code
  • optimize cold start, isolation, and observability
  • Ship unified interfaces for multiple model sizes and providers
  • integrate with open tool ecosystems such as MCP-style connectors for data and actions
  • Develop an evaluation platform for online and offline assessments, A/B tests, safety checks, and regression gates that improve agent reliability over time
  • Partner with Research to deliver new agent capabilities end to end—from prototype to production

Requirements

  • Experience building agent applications with tool-calling, context engineering, or open connector integrations
  • Fluency with LLM APIs, prompting strategies, and orchestration patterns (e.g., LangChain, LlamaIndex, or custom pipelines)
  • Experience with retrieval systems (e.g., semantic and lexical retrieval, vector DBs, efficient kNN), function calling, tool use, or agentic workflows
  • Strong coding skills in one or more of: Python, Java, Go
  • Comfortable with service design, APIs, and data models for high-throughput systems
  • Working knowledge of containers and kubernetes concepts
  • Familiarity with metrics, tracing, on-call rotations, and incident response practices
  • Self-motivated with a willingness to take ownership
  • Strong communication skills and ability to work collaboratively in a team environment

Nice to have

  • Prior work on agent orchestration pipelines: task routing, planning, memory graphs, vector search, or browser automation
  • Experience with evaluations, preference optimization, or RL to improve LLM reliability

What we offer

  • Generous Time Off: 14 paid holidays, flexible PTO for salaried employees, and accrued time off for hourly employees
  • Comprehensive Health Plans: Medical, Dental, and Vision coverage for all full-time employees and their families
  • Generous HSA Contribution: If you choose a High Deductible Health Plan, Abridge makes monthly contributions to your HSA
  • Paid Parental Leave: Generous paid parental leave for all full-time employees
  • Family Forming Benefits: Resources and financial support to help you build your family
  • 401(k) Matching: Contribution matching to help invest in your future
  • Personal Device Allowance: Tax free funds for personal device usage
  • Pre-tax Benefits: Access to Flexible Spending Accounts (FSA) and Commuter Benefits
  • Lifestyle Wallet: Monthly contributions for fitness, professional development, coworking, and more
  • Mental Health Support: Dedicated access to therapy and coaching to help you reach your goals
  • Sabbatical Leave: Paid Sabbatical Leave after 5 years of employment
  • Compensation and Equity: Competitive compensation and equity grants for full time employees
