• Drive Technical Strategy: Define the long-term technical vision for Brain Health in partnership with product and clinical leadership, balancing immediate delivery with scalable, fault-tolerant infrastructure.
• Lead & Mentor: Act as a technical beacon for the team, mentoring engineers, fostering a culture of technical excellence, and driving cross-functional collaboration across data science, clinical, and platform teams.

• A Strategic Builder: You don't just write code; you architect systems that scale. You have a deep understanding of distributed systems and can navigate the complexity of building AI-driven products in a regulated healthcare environment.
• A "Learn-it-all": You stay on the bleeding edge of AI and software engineering, constantly evaluating emerging technologies to optimize performance and improve the platform.
• A Cross-Functional Leader: You thrive in multidisciplinary environments, translating complex technical concepts for clinical and product stakeholders to ensure our solutions are both clinically sound and technically robust.

• Have led the design and delivery of complex, user-facing products end-to-end — across product surfaces, backend services, and AI/ML systems.

• Have worked in early-stage or fast-moving, rapidly evolving environments, and have ideally built products from 0 to 1.
• Are technically proficient in modern AI application development, with demonstrated depth in working with LLMs (prompt engineering, RAG, agentic systems, evals) and a strong fullstack foundation (e.g., Python, TypeScript/NestJS).
• Take a product-focused approach to building AI solutions that are robust, safe, and genuinely useful in users' hands.
• Have successfully driven cross-team alignment to get impactful work shipped, and work with influence over authority.
• Have experience establishing engineering standards, system architectures, and development best practices — especially around evaluation, safety, and reliability for AI systems.
