Company mission
To make brain health accessible for everyone by transforming the way we measure, monitor, and maintain brain function.
Role
Who you are
- 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 in Swift/SwiftUI (and/or UIKit), Xcode tooling, Instruments, and Apple platform fundamentals (background tasks, permissions, Keychain, App Store Connect, TestFlight)
- Strong React Native fundamentals (bridge/native modules, performance profiling, Hermes, Metro/bundling, OTA, navigation)
- Proven track record designing reusable component systems (design tokens, accessibility, theming, API ergonomics, documentation)
- Hands-on experience using AI to accelerate coding (scaffold code/tests, refactors, docs) and productizing AI in-app (safe prompts, evaluation, guardrails)
- Depth in mobile 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
Desirable
- 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 of design systems or component libraries used across multiple apps/teams
- Experience with on-device ML or efficient edge inference patterns
- Experience architecting B2B and Consumer facing applications
What the job involves
- We’re looking for a Staff Software Engineer to lead our mobile apps across iOS (Swift) and React Native. You’ll set technical direction, design and build reusable component libraries, and raise the bar on quality, performance, and accessibility
- You’ll also champion AI-assisted engineering—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
- Own the mobile architecture across iOS (Swift/SwiftUI/UIKit) and React Native—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 responsibly—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
Our take
An aging population in the US means that Alzheimer's is on the rise. This is an extremely costly illness, due in large part to direct care requirements. However, Azheimer's can be present up to 20 years before symptoms arise, and if caught early can be treated far more effectively.
Linus Health's digital screening platform offers doctors a quick, user-friendly test for cognitive health. Its AI-powered assessments analyze performance on the company’s scientifically validated test and draws out insights based on performance that would be difficult to detect with the human eye.
The platform also automates numerous workflows around neurological diagnostics, cutting hours per week of manual administration. Its rapid growth and impressive fundraising makes sense as Alzheimer's becomes a bigger and bigger issue. And the company continues to make strong partnerships as it positions itself as a key player in this fight.
