## Job description

## ABOUT US

We're tackling one of healthcare's most critical challenges in medical imaging and diagnostics. Our company operates at the intersection of cutting-edge AI and clinical practice, building technology that directly impacts patient outcomes. We've assembled one of the industry's most comprehensive and diverse medical imaging datasets and have a proven product-market fit with a substantial customer pipeline already in place.

## ROLE OVERVIEW

We’re looking for a Product Engineer who thrives at the intersection of product and engineering. You should have strong coding skills across the stack, a deep appreciation for intuitive user experiences, and the technical expertise to design end-to-end systems.

In this role, you’ll own product features end-to-end, from ideation through to building responsive, user-centric web apps and backend services. You’ll partner directly with users, both internal and external, technical and non-technical to build intuitive solutions that will allow us to effectively scale our business.

## KEY RESPONSIBILITIES

- Work with our clients to build and maintain the integration layer connecting our applications to customer systems, including PACS, RIS, and EHRs, using medical communication protocols such as DICOM and HL7 through site-to-site VPN
- Onboard with new clients, partnering closely with their team to understand their systems in order to implement an optimal custom integration
- Build and maintain key internal applications that allows us to effectively distribute case assignments, conduct Radiologist peer reviews, and provide critical insight and analytics into our business and how well it is doing.
- Proactively identify process gaps, inefficiencies, automation opportunities, and risk in the current processes
- Fully manage medium-to-large projects independently by having deep experience in domain knowledge, both functionally or technically, and make independent design decisions

## QUALIFICATIONS

- Have 5+ years of experience developing user-facing software applications
- Deep proficiency in modern web application technologies for the frontend (e.g., TypeScript, React) and backend services, with a strong understanding of web architecture; especially in interactive and real-time applications with performance considerations.
- A strong, independent contributor who is comfortable navigating ambiguity, works in uncharted territory, and also has curiosity to learn a complex business area.
- Experience in building products that customers love. You’ll have come from a background where you have set and led the technical direction of a product from an early stage
- Skill in quickly understanding systems design tradeoffs and keeping track of rapidly evolving software systems, working through trade-offs, and balancing competing priorities
- Excellent communication skills and the ability to work cross-functionally with technical and non-technical stakeholders, including external customers and vendors
- Experience operating in a startup or startup-like environment, i.e. a small, fast-moving team with high autonomy

The anticipated annual base salary for this position is up to $250,000. This range does not include any other compensation components or other benefits for which an individual may be eligible. The actual base salary offered depends on a variety of factors, which may include as applicable, the qualifications of the individual applicant for the position, years of relevant experience, specific and unique skills, level of education attained, certifications or other professional licenses held, and the location in which the applicant lives and/or from which they will be performing the job.

## About Epsilon Labs, Inc.

## Company Overview
- **One-liner**: Epsilon Health is a tech-enabled teleradiology practice that combines board-certified radiologists with proprietary AI to deliver accurate, rapid diagnostic reports.
- **Entity Type**: Private (venture-backed startup, pre-Series A)
- **Headquarters**: San Francisco, CA, USA
- **Founded**: 2024
- **Founders**: Not publicly disclosed (key executives include Dr. Roi Bittane – Chief Medical Officer, and Rustin Rassoli – Founder/Executive; team also includes leaders from Google DeepMind, Meta, and Twitch)

## Core Business
- **Primary industry**: Healthcare – Teleradiology / Medical Imaging / Health Tech
- **Target customers**: B2B – Imaging centers, hospitals, health systems, and payers in the United States
- **Mission**: “To make sure no diagnosis is missed, delayed, or wrong.”

## Products & Services
- **Epsilon Platform (Proprietary AI + Workflow)**: A SaaS-enabled interpretation service that integrates AI models for triage, flagging critical findings, and automating busywork. Radiologists use the platform to increase speed and accuracy while reducing burnout.
- **Teleradiology Services**: 24/7 remote radiology interpretation with a turnaround time of 24 hours or less; critical findings flagged immediately. Combines human expertise with AI assistance.

## Market Standing
- **Valuation/Market Cap**: Not publicly available (early-stage startup)
- **Key Metric**: Total funding not disclosed; backed by venture studio Atomic (based on team background). Headcount ~6 employees (as of mid-2025).
- **Notable Investors/Partners**: Implied backing from Atomic; no formal funding announcement found.
- **Growth Signals**: Founded in 2024, actively hiring for Research Scientist, Research Engineer, and Senior Backend Engineer roles. Addresses a massive market gap: 700 million scans/year in the US, with a radiologist shortage projected to reach 15,000 by 2030.

## Competitive Advantages
- **Integrated AI + Human Workflow**: Unlike point solutions that fail in production, Epsilon builds AI directly into its practice, allowing continuous iteration across hospitals and imaging centers.
- **Speed & Accuracy**: 75% of critical findings flagged immediately; reports delivered in 24 hours or less.
- **Radiologist-Centric Design**: Removes administrative busywork to let radiologists focus on interpretation, reducing burnout.
- **Team Depth**: Combines clinical leadership (former CMO of Envision Radiology) with top-tier ML engineering (Google DeepMind, Meta, Twitch alumni).

## Strategic Focus
- **Scale the practice** to meet growing imaging demand by onboarding more radiologists and imaging center partners.
- **Deepen AI capabilities** for automated triage, detection, and workflow optimization.
- **Expand partnerships** with health systems and payers to improve patient outcomes and reduce costs.

## Why Work Here
- **Culture**: “Radiology rebuilt from the ground up” – a mission-driven environment focused on solving a critical healthcare crisis. Emphasis on collaboration between radiologists, engineers, and technologists.
- **Work Policy**: Hybrid – in-office presence in San Francisco (SOMA area) with remote flexibility for certain roles (Built In lists both “In-Office” and “Remote Workspace” options).
- **Engineering Culture**: Small, high-impact team with autonomy; roles span ML infrastructure, computer vision, and backend systems. Opportunity to shape the product from an early stage.
- **Perks**: Not detailed, but typical for early-stage health tech (likely equity, health benefits, and the chance to work on life-saving technology).
