Linus Health
The Role:
We00re looking for a Staff Software Engineer to lead our mobile apps across iOS (Swift) and React Native. You00ll set technical direction, design and build reusable component libraries, and raise the bar on quality, performance, and accessibility. You00ll also champion AI-assisted engineeringe—both to accelerate development (e.g., code generation, testing, refactors, documentation) and to integrate AI-powered visualizations that help clinicians and patients make sense of complex brain-health data. This role is highly cross-functional and pivotal to our mission. What You00ll Do:
Own the mobile architecture
across iOS (Swift/SwiftUI/UIKit) and React Nativeffffff—modularity, performance, security, and observability Create and maintain reusable mobile component libraries
(design-system alignment, theming, accessibility, localization, dark mode) Ship AI-enabled features
that surface insights visually (charts/plots/progressions) and responsiblyffff, privacy-by-design, auditable outputs Raise engineering standards : testing (unit/snapshot/e2e), CI/CD for mobile, OTA strategies, release automation, crash analytics, and telemetry Mentor and unblock
engineers; drive clear design docs, ADRs, and code reviews; partner deeply with Product, Design, Data Science/Medical, and Security Lead cross-team initiatives
(performance, reliability, offline/edge patterns, network/data sync, app startup time, bundle size reduction) Champion AI-assisted workflows
to boost delivery speed and quality (intentional prompts, verification practices, secure usage guidelines) Collaborate with Data Science/Medical
to integrate model outputs safely and clearly into the UI, including uncertainty and context visualization About You:
Must Haves:
10+ years of software engineering experience with significant time in mobile; 5+ years building and shipping iOS apps in Swift; 3+ years with React Native at scale. Expert inSwift/SwiftUI (and/or UIKit), Xcode tooling, Instruments, and Apple platform fundamentals (background tasks, permissions, Keychain, App Store Connect, TestFlight). StrongReact Native fundamentals (bridge/native modules, performance profiling, Hermes, Metro/bundling, OTA, navigation). Proven track record designingreusable component systems (design tokens, accessibility, theming, API ergonomics, documentation). Hands-on experience usingAI to accelerate coding (scaffold code/tests, refactors, docs) and productizing AI in-app (safe prompts, evaluation, guardrails). Depth inmobile data flows (REST/gRPC, GraphQL, streaming), offline-first sync, error handling, and app state management. Quality mindset: unit/UI/e2e testing (XCTest, snapshot testing, Detox), monitoring, crash analytics, metrics/SLOs. Security and privacy literacy suitable for healthcare contexts (e.g., PII/PHI handling patterns, least-privilege, secure storage). Clear technical communication: design docs, ADRs, tradeoff analysis, and stakeholder alignments Nice To Haves:
Experience in digital health or clinical workflows; familiarity with regulated environments Data visualization skills (e.g.,Charts on iOS, D3/Reanimated/Skia in RN) and communicating uncertainty Native Android familiarity (Kotlin) or cross-platform build/release expertise Prior ownership ofdesign systems or component libraries used across multiple apps/teams Experience withon-device ML or efficient edge inference patterns Experience architecting B2B and Consumer facing applications How You Embody Our Values:
At Linus, we live by
Be Real, Be Wise, Be Noble, Be a Team, Be Masters of Our Craft, Think Big and Act Bold . In this role, you will: Be Real:
communicate tradeoffs, risks, and results candidly—early and often Be Wise:
select architectures and AI use cases with evidence, measurement, and clear mitigations Be Noble:
prioritize privacy, safety, and clinical trust in every feature we ship Be a Team:
elevate others through mentoring, helpful reviews, and excellent docs Be Masters of Our Craft:
set exemplary standards for mobile quality, performance, and maintainability (including AI-assisted workflows) Think Big and Act Bold:
lead step-change initiatives (e.g., shared component libraries, AI-driven visualization) with staged rollouts and measurable outcomes Linus Health is an equal opportunity employer. All qualified candidates will receive consideration for employment without regard to race, religion, color, national origin, sexual orientation, gender, gender identity or expression, age, genetic information, disability or any characteristic protected by law. We believe that diversity is critical to the growth of our company and understand the importance of fostering an environment where everyone has a voice. We are also committed to providing reasonable accommodations for candidates with disabilities during the recruiting process. If you are in need of assistance due to a disability, please contact us.
