About The Position

We’re hiring a Staff Full-Stack Engineer to help drive the next generation of AI-powered healthcare experiences. This is a highly technical role with broad cross-functional impact. You’ll partner with product teams across the company — including Pharmacy, E-commerce, Care, and Core Platform — to design and ship AI-powered features for both external users and internal teams. You will set technical direction, lead architectural decisions, and create the foundational systems that enable fast, safe, and reliable AI development. This role is ideal for someone who enjoys fast iteration, values a product-driven mindset, and can balance high velocity with uncompromising standards for safety and quality.

Requirements

• 8+ years of professional experience across backend services, frontend applications, distributed systems, and data/ML tooling.
• Strong proficiency in TypeScript and Python, with experience building production systems in both languages.
• Deep familiarity with LLM- or ML-based systems and the architectural patterns needed to operate them safely at scale.
• Experience leading major technical initiatives that span multiple teams or product areas.
• A product-driven mindset with a bias toward fast, incremental delivery and continuous learning.
• Strong communication and collaboration skills across engineering, product, design, operations, and clinical teams.
• A deep appreciation for safety, privacy, and security — ideally with experience in a regulated domain such as healthcare, fintech, or life sciences.

Nice To Haves

• Experience with Databricks, Cloudflare Durable Objects, vector databases, or edge-based AI orchestration.
• Prior work on AI evaluation systems, LLM behavior monitoring, or safety frameworks.
• Contributions to open-source SDKs or complex infrastructure projects.
• Experience building tools that significantly increase developer velocity.

Responsibilities

• Lead architecture and platform development
• Design and own core AI workflow platforms, orchestration systems, and shared SDKs that power intelligent healthcare experiences.
• Build scalable, reliable systems for LLM orchestration, grounding, evaluation, and agent-like workflows.
• Create reusable frameworks and patterns that other engineering teams can adopt across the company.
• Drive multi-quarter technical initiatives and help bridge AI research prototypes with production-grade systems.
• Partner closely with Product across multiple verticals
• Work with Pharmacy, E-commerce, Care, and Operations to bring AI-powered features to life, from patient-facing journeys to internal efficiency tools.
• Collaborate on product strategy, helping translate ambiguous ideas into clear technical plans.
• Support teams in releasing features quickly through incremental, high-velocity delivery cycles.
• Ensure user-facing AI experiences meet expectations for performance, reliability and usability.
• Champion safety, privacy, and clinical integrity
• Develop evaluation frameworks and observability systems that measure AI behavior, grounding, safety, and quality.
• Establish guardrails and patterns that ensure all AI interactions comply with HIPAA, security-by-design, and privacy-first principles.
• Work with clinical, legal, and AI safety partners to ensure our systems are trustworthy and appropriate for healthcare use.
• Elevate engineering excellence
• Mentor engineers and help cultivate strong engineering practices across the Applied AI organization.
• Lead design reviews and contribute to architectural governance across engineering teams.
• Improve developer experience and remove platform bottlenecks that slow down product teams.
• Raise the overall quality bar by championing clear standards for reliability, observability, testing, and iteration.
• Build and ship across the full stack
• Develop features and infrastructure using TypeScript (AWS, Cloudflare Workers, React/Next.js) and Python (Databricks, orchestration, evaluation).
• Integrate and evaluate LLMs and ML systems through unified AI gateway.
• Build secure APIs and connectors that link to domains like EHR, Pharmacy, Payments, Orders, and Care.
• Contribute to shared libraries that standardize schemas, tool contracts, and developer experience.

Benefits

• Competitive salary & equity compensation for full-time roles
• Unlimited PTO, company holidays, and quarterly mental health days
• Comprehensive health benefits including medical, dental & vision, and parental leave
• Employee Stock Purchase Program (ESPP)
• 401k benefits with employer matching contribution
