Design, build and improve the core components of the AIMS including integration framework, metric computation system, model full lifecycle management system, and model onboarding tools.

• Prototype and ship new AI management solutions in both technological (pre-evaluation, post-evaluation, LLM monitoring, agent monitoring) and healthcare (bias, governance, compliance, performance, ROI, etc.) verticals.

• Break down ambiguous, high-level problems into concrete technical solutions and engineering plans.

• Work autonomously and collaboratively with Product, ML, Security, Infrastructure and other engineering teams.

Qualifications:

• 5+ years of experience in building backend systems and AI applications.

• You can design and defend architecture decisions with privacy and security considerations built into your thinking.

• You've taken a vague product requirement and shipped a working system without a detailed spec handed to you.

• Excellent communication skills with the ability to engage non-technical stakeholders from business and hospital teams.

Preferred Qualifications:

• Hands-on experience with Java, Spring Boot, Python, Postgres, Azure, and Kubernetes.

• Experience in startup or early-stage environments, including building and shipping products from 0 to 1.

• Experience working with AI/LLMs in production, healthcare data standards (HL7/FHIR), or systems in highly regulated industries.
