A well-funded, rapidly growing Series A healthcare AI startup is hiring a Senior Software Engineer to help scale the core systems behind an AI-powered clinical review platform.

You'll join a small engineering team at an important stage of growth, working directly with senior technical and product leadership. This is a hands-on role with significant ownership, where you'll design fault-tolerant backend systems, build AI-driven data and document-processing workflows, and help establish engineering standards as the platform scales.

• Mentor engineers through code reviews and architectural guidance.
• Partner closely with product and customer-facing teams.

• 6+ years of backend software engineering experience.
• Strong professional experience with Python, TypeScript, and AWS.
• At least 2 years at a venture-backed, high-growth startup.
• Experience building and scaling distributed systems in production.
• Clear end-to-end ownership of high-impact engineering projects.
• Strong systems-design fundamentals and ability to explain architectural trade-offs.
• Stable career progression, ideally including internal promotions.
• Excellent communication and a product-first approach.
• Ability to work from the NYC office Monday through Thursday.
• Existing permanent U.S. work authorization; visa sponsorship is not available.

Nice to have

• B2B SaaS experience.
• Production AI/ML or LLM applications.
• Document-processing or data-extraction systems.
• Healthcare or life-sciences experience.
