Mentor and coach junior engineers, perform code reviews, and drive engineering best practices across cross-functional teams.
Collaborate with UX researchers and accessibility specialists to ensure apps meet WCAG and inclusive design principles for diverse populations.
Design robust data models and schemas for longitudinal health data, ensuring efficient query performance and data lineage for analytics and compliance.
Coordinate with regulatory, legal, and compliance teams to support audits, prepare HIPAA, SOC2, and other evidence, and implement product changes required for certifications.
Optimize system cost and performance on cloud platforms (AWS, GCP, Azure), including autoscaling, caching strategies, and database tuning.
Drive vendor integrations (telehealth, biometric sensors, coaching platforms) — manage API contracts, SLAs, and versioning.
Participate in cross-functional planning, sprint ceremonies, and help prioritize technical debt that impacts reliability, privacy, or scalability.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis.
Contribute to the organization's data strategy and roadmap.
Collaborate with business units to translate data needs into engineering requirements.
