Role
Who you are
- We’re looking for strong research engineers who want to build the core models and algorithms behind our core platform and agents. People here own their work end-to-end, ship real improvements, and are trusted to make high-impact technical decisions
- 5+ years of experience with a minimum of 3+ in AI/ML engineering or research
- Prior experience post-training and deploying LLMs in production environments
- Fluency in Python and modern ML tooling (training, evaluation, inference, data pipelines)
- Track record of taking research ideas from prototype → reliable, measurable production impact
- Strong experimental judgment: formulating hypotheses, establishing useful baselines, designing evaluations, and interpreting results carefully
- (Bonus) Prior experience utilizing and improving speech-to-text (STT), text-to-speech (TTS) models, and/or duplex models
- A PhD is not required. We value demonstrated research ability and the quality of the models, experiments, and systems you have helped build
What the job involves
- As a Research Engineer, you’ll be responsible for building industry-leading healthcare AI models and model pipelines that power Assort’s voice agents and overall patient platform, taking them all the way from idea to production
- You’ll own large initiatives that push the boundary of what models and agents can accomplish in the healthcare space while maintaining high levels of reliability, efficiency, and precision of accomplishing tasks
- Lead research and engineering efforts to improve core conversational capabilities in production, including instruction following, tool calling, retrieval, and memory
- Investigate research questions in speech and audio, and design experiments to test hypotheses about model behavior and capabilities
- Build and iterate on end-to-end models and pipelines that optimize for quality, efficiency, and user experience
- Identify opportunities for model-task optimization to ensure the right model architectures are used for different tasks based on performance, latency, and cost
- Partner with platform and product engineers to integrate new models into production systems
- Break down ambiguous research ideas into clear, iterative milestones and roadmaps
- Train, fine-tune, validate, and further develop models built in-house at Hume and models developed by our customers
- Design evaluation protocols and benchmarks that measure model quality, generalization, robustness, and progress against research objectives
- Analyze datasets, model outputs, and failure cases; compare training approaches and use the evidence to guide the next round of model development
Our take
Assort Health is a fast-growing healthcare tech company focused on improving how patients connect with providers by designing tools for the complexity of modern healthcare systems.
What Assort really focuses on is a problem most people have experienced, struggling to book or manage an appointment. Clinics are often overwhelmed with calls, and usually understaffed, creating long wait times and the opportunity for mistakes. Assort's voice agents step in to handle those calls, figure out what patients need, and get them booked in correctly.
Already, clinics using Assort are seeing more appointments booked and a smoother experience for all. The company is also starting to expand into other areas like referrals and billing. In just a short amount of time, it has scaled quickly across the US, supporting thousands of providers and raising over $222M, which shows just how much demand there is for fixing these systems.
