Software Engineer, Generative AI

At Abridge, we’re transforming healthcare delivery experiences with generative AI, enabling clinicians and patients to connect in deeper, more meaningful ways. Our mission is to power deeper understanding in healthcare. We’re a growing team of practicing MDs, AI scientists, PhDs, creatives, technologists, and engineers working together to empower people and make care make more sense. Our offices are located in the Mission District in San Francisco, the SoHo neighborhood of New York, and East Liberty in Pittsburgh.

About the role

We are looking for GenAI Software Engineers of all levels who are passionate about making a positive impact. You’ll collaborate closely with a cross-functional team of researchers, clinicians, and engineers to translate cutting-edge language model capabilities into dependable, real-world clinical systems. Your focus will be on designing advanced LLM-driven workflows that can reason through complex clinical contexts, leverage agentic capabilities and structured tool use, navigate branching chains of LLM calls, integrate seamlessly with retrieval systems, and consistently generate outputs that meet the highest standards of clinical reliability and trust.

A major part of this role will involve developing and applying rigorous evaluation frameworks (both automated and human-in-the-loop) to continuously assess accuracy, robustness, multilingual capabilities, and more. You’ll design experiments to probe failure modes, simulate edge cases, and stress-test LLM workflows under realistic load and challenging real-world conditions. You’ll apply a disciplined, data-driven approach to understanding model behavior—developing tools to measure system performance, conduct A/B tests against established baselines, and generate clear, actionable insights that inform deployment decisions.

This high-impact role will own the end-to-end productionization of LLM workflows: deploying models into low-latency, high-uptime environments, building monitoring and observability systems, implementing post-processing guardrails, and managing workflow versioning.

Responsibilities

• Design and build agentic systems that turn LLMs into composable, dependable tools—leveraging retrieval, tool use, agentic reasoning, and structured outputs.
• Collaborate with ML and infra engineers to scale and optimize agentic workflows, managing latency, context windows, and model choice.
• Write high-quality, modular code that’s graceful under failure, flexible to change, and easy to iterate on.
• Own major architectural decisions—how we architect workflows, define data flow, cache intermediate state, and structure generative outputs.
• Drive rigorous evaluation: build benchmark datasets, develop automated and human-in-the-loop frameworks, design experiments to surface failure modes and edge cases, run A/B tests to inform deployment, and distill insights from clinician feedback to evaluate and guide model improvement.
• Leverage frontier capabilities: rapidly prototype with new models and model capabilities, open-source tools, and novel prompting techniques.

Requirements

• 3+ years of experience building production-grade systems, with 1–2+ years focused on LLM-powered or agentic products.
• Deep fluency with LLM APIs, prompting strategies, and orchestration patterns (e.g., LangChain, LlamaIndex, custom pipelines).
• Experience with retrieval systems (e.g., semantic and lexical retrieval, vector DBs, efficient kNN), function calling, tool-use, or agentic workflows.
• Working knowledge of model evaluation, experience building diverse datasets, conducting both automated and human-in-the-loop evaluations, running A/B tests, and working with subject matter experts to guide model improvement.
• Strong Python fundamentals—including ability to write clean code, design comprehensive test-cases, and familiarity with core language features and standard libraries; experience with async programming, performance profiling, packaging, and deployment tooling is strongly preferred.
• Must be willing to work from our SF or NYC office at least 3x per week. Relocation assistance is available for candidates willing to move to San Francisco.

We value people who are eager to learn new things and recognize that great team members might not perfectly match a job description. If you’re interested in the role but aren’t sure whether or not you’re a good fit, we’d still like to hear from you.

Benefits

• 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.
• Competitive compensation and equity grants for full-time employees.
