Senior Software Engineer

Overview

About us

ecares health is a healthcare technology startup spun out of Essen Health Care, a large multispecialty provider group in the Bronx. We're building the care coordination OS that brings concierge medicine to underserved communities. Our platform powers proactive outreach, intelligent care programs, and automated scheduling, helping provider groups ensure no patient falls through the cracks.

Through our unique relationship with Essen Health Care, we have access to clinical and operational experts who help drive our product strategy and refine our vision. Our platform is currently live with active users at Essen, and we are finalizing expansion to more practices across New York City in the coming months.

Why ecares

Healthcare is full of absurd complexity: a patient has two tax IDs, three insurance plans, referrals that expire in ways that don't make sense, and an EHR that was built in 1999. A clinical rule that sounds simple ("high-risk diabetes patients should see endocrinology every 90 days") touches eligibility logic, scheduling constraints, provider credentialing, and half a dozen integrations.

There are a hundred health tech startups with AI in their names, but few are interested in leveraging LLMs, and other cutting-edge technology, to build the operational infrastructure that makes care coordination work. And none are as committed as we are to the belief that technology is society's strongest lever to improve health at a population level.

Job Summary

Position Title: Senior Software Engineer

The role:

We're hiring Software Engineers to join our founding engineering team. You'll take well-scoped technical work from our principal engineers and ship it, end to end: features, integrations, bug fixes, infrastructure improvements. You'll work across the full stack, and you'll have full ownership over what you build.

Responsibilities

What you'll own

The work here spans the full platform. Some examples of what you might be building in a given week:

• Implementing clinical rules that determine which patients need outreach and for what (e.g., a diabetic patient who hasn't seen endocrinology in 6 months)

• Building AI automations that interact with payor and Medicaid systems to understand and leverage insurance benefits on behalf of patients

• Working on EHR integrations that pull patient data, push appointment updates, and keep systems in sync

• Using LLMs to deliver critical patient context to care coordinators so they can educate and engage patients

• Improving infrastructure: API performance, data pipelines, deployment tooling, test coverage

Day to day, you'll pick up work from a prioritized queue, build it well, write tests, submit PRs, and ship. You'll work with principal engineers when the technical approach needs clarification and participate in code review across the team.

Qualifications

What we're looking for

• 5+ years of professional software engineering experience

• Comfortable working across the stack, backend and frontend

• Strong fundamentals: data structures, system design basics, debugging, writing testable code

• Self-directed and comfortable with focused, independent work

• Thorough. You think through edge cases, write tests, and care about getting it right

• Excited to own features and work with the team to deliver them our users

Our stack: Python (FastAPI), React/TypeScript, MSSQL, Redis, Azure (Container Apps, Static Web Apps, DevOps Pipelines), Terraform. The ability to learn and contribute is more important than matching our stack exactly.

Nice to have

• Health tech or healthcare experience

• Experience with EHR systems or healthcare data

• Experience working in compliance-heavy or regulated environments

• Familiarity with Azure cloud services

• Background working with underserved communities or in mission-driven organizations

Location

Based in the Bronx, co-located with Essen Health Care. We sit next to the care coordinators, clinicians, and operators who use the platform every day and work in a community that we serve. Instead of scheduling a user research session, you can walk down the block and see someone using what you built.

Hybrid: 3 days on-site, 2 days remote.

Why this role

You'll be a founding engineer building something from the ground up. You'll make decisions that shape the platform for years. You'll learn healthcare deeply, which is a career-making domain. And you'll work alongside strong engineers on a small team with no bureaucracy, and where what you build goes directly into the hands of the people who deliver care.

Equal Opportunity Employer

Essen Health care is proud to be an equal opportunity employer, and we seek candidates who desire to work in and serve an ethnically diverse population.
