## Job description

## ABOUT LUMINAI

Healthcare operations have always depended on people to bridge the gaps that technology couldn't. It relies on complex manual work to carry out critical internal processes, yet most health systems don’t have enough resources to properly automate these tasks, leaving them stuck in outdated, labor-intensive SOPs.

Luminai structures the chaos, automates the manual handoffs, and deploys end-to-end workflows across every system, providing the integrated intelligence layer to improve processes over time. By delegating to autonomous AI systems those mission-critical workflows that previously expended valuable human time, Luminai allows doctors and administrators to do what they do best: Focus on Patients.

We've raised $60M in funding, including our recent Series B led by Peak XV Partners (formerly Sequoia India), with participation from healthcare-focused Define Ventures and continued support from General Catalyst and Y Combinator. We're backed by some of the best investors in Silicon Valley, including Kevin Weil (Chief Product Officer at OpenAI), Arash Ferdowsi (co-founder of Dropbox), Katie Stanton (former VP Global Media, Twitter), and CEOs of companies such as Flexport, Notion, Front, Ramp, and Twitch.

Our team is in-office 4 days a week (Monday - Friday, Wednesday optional WFH) in either San Francisco, California or New York, New York.

## About the role

As a Software Engineer working on Platform, you will design, build, and improve the core infrastructure and systems that Luminai runs on, ensuring the platform is reliable, scalable, and ready to support rapid growth.

## What You'll Do

- Lead platform and backend projects from planning through implementation
- Build and maintain shared libraries, services, and internal APIs that product engineers / FDEs rely on
- Improve the developer workflow: build times, CI/CD pipelines, test infrastructure, and local development setup
- Contribute to core platform direction, using system improvements to support higher scale and reliability
- Maintain and extend Luminai infrastructure across compute, data, and deployment systems
- Champion good engineering practice through code review, testing, and maintainability
- Design and implement robust APIs, authentication, and middleware that hold up under load
- Harden production systems with sensible defaults around access control and secrets management

## What We're Looking For

- Proven track record of shipping high-quality code in challenging projects
- Significant experience working with distributed systems, cloud infrastructure, and backend services (Python and/or similar languages)
- Working knowledge of security best practices for cloud infrastructure and production systems (access control, secrets management, secure networking)
- Exceptional problem-solving skills and an ability to work across the stack

## About Luminai

## Market Standing
- **Valuation**: Not publicly disclosed.
- **Key Metric**: $60.8M in Total Funding raised across multiple rounds.

## Competitive Advantages
- **Deep Focus**: Solely focused on solving a massive ($1.2T cost problem), specialized problem for a concentrated market of 200 major health systems. This creates a deep moat compared to horizontal automation platforms.
- **Trust & Compliance**: Built "AI-native from day one" with HIPAA, SOC 2, and GDPR compliance, and flexible deployment options that meet the stringent security requirements of healthcare enterprises.
- **Interconnected Platform**: Instead of siloed point solutions, each use case they solve (e.g., Referral Intake) connects and compounds on the platform, making the entire system smarter over time.
- **Leadership & Advisors**: Backed by a world-class team with deep domain expertise in AI (OpenAI) and healthcare (Cleveland Clinic, Humana).

## Strategic Focus

## Why Work Here
- **High-Impact Mission**: The opportunity to work on a generational problem—fixing U.S. healthcare operations. The company describes this as "building the healthcare operating system that should have existed all along."
- **Strong Engineering Culture**: The company is tech-heavy (41% of workforce is technical), with a focus on building AI at scale. Alumni come from top-tier companies like Palantir, Stripe, and Notion.
- **Culture & Values**: Company commandments emphasize creating meaningful impact now and delivering value, with a focus on outcomes over obstacles.
