About Optexity

Optexity is a product-driven research lab building clinical reasoning and computer use models on data no other lab can reach. We deploy directly inside clinics and hospitals — including systems with no APIs, using integration infrastructure we've built and open-sourced — and in return become their preferred partner. That gives us proprietary clinical reasoning trajectories from practicing physicians, and a feedback loop between real patient encounters, our models, and the products built on top of them.

We're a small, fast-moving founding team with multiple published papers in NeurIPS, ICML, CVPR etc and background from Apple, Amazon, Microsoft, CMU, IIT.

We are backed by world-class investors and leaders like Jeff Dean, Neotribe VC, PearVC, Together Fund and Zapier Fund.

How we work

Customer obsession — we start with the customer and work backwards

Intellectual honesty — ideas matter more than titles; we communicate directly and assume good intent, even in disagreement

Bias for action — we build and learn with customers rather than debate in the abstract

Extreme ownership — we own outcomes, not just tasks, and see problems through

About the role

You are a software engineer who works directly with our customers. You will be deployed inside practices, clinics and hospitals in New York, understand how doctors and staff actually work, and build the integrations and product features that make Optexity work in their environment. Many of these systems have no APIs, so you will often be building the way in. You will own the customer’s technical outcome from first meeting to daily usage.

Deploy and set up Optexity inside practices and clinics, including systems with no APIs, using the integration infrastructure we’ve built and open-sourced

Sit with doctors and staff to understand their workflows and requirements, and turn them into working software

Build and improve data pipelines and integrations with EMRs and other clinical systems

Work with the core team on our search and chat system, and bring real customer feedback into the product

Debug and resolve customer issues quickly, and own them until they are fixed

Help drive customer success: onboarding, training, and increasing usage

Make general solutions from one-off customer problems, so each deployment makes the next one faster
