About ExpiWell

ExpiWell is a mobile platform built for experience sampling and ecological momentary assessment (EMA) research. We help researchers and clinicians collect real-time data from participants in their daily lives through intuitive mobile experiences and survey tools.

About the Role

We are seeking a Senior / Staff iOS Native Software Engineer to own the technical direction, system design, and long-term evolution of the ExpiWell mobile ecosystem. This is a high-level engineering role requiring deep, battle-tested expertise in native Apple ecosystems.

This is not a generalist web or frontend JavaScript role. Our core platform is a native iOS application, and your foundational engineering strength must be rooted deeply in native Apple frameworks. However, because we are driving our transition toward a unified mobile platform, architectural experience with React Native and the JavaScript/TypeScript ecosystem is a strict requirement. You will be the bridge that ensures our native infrastructure integrates seamlessly with our cross-platform future while adhering to rigorous clinical data standards.

Our Current Codebase & Tech Stack

To give you an exact picture of what you will be stepping into, our repository and architecture primarily center around:

• Swift: Modern native core implementation, native modules, and platform architecture.

• Apple Frameworks & Kits: Deep application of HealthKit, SensorKit, CoreLocation, and CoreMotion for participant telemetry and health metrics collection.

• JavaScript / TypeScript: React Native expansion for shared business logic and cross-platform feature parity.

What You'll Do

• Architectural Leadership: Own the overarching architecture, design patterns, and technical roadmap for our production iOS (Swift) and React Native applications.

• Biometric & Biomechanic Telemetry: Design and optimize data collection services that query and process passive/active research metrics using HealthKit and SensorKit.

• Core Mobile Telemetry: Optimize hardware-level native services including location monitoring (CoreLocation) and motion processing frameworks (CoreMotion) for geofencing and location-based survey triggers.

• Data Strategy & Privacy: Architect bulletproof offline-first data persistence layers using CoreData and Secure Keychain, adhering strictly to global compliance baselines (HIPAA, GDPR, and SOC 2).

• Bridge Architecture: Write high-performance native bridging modules to connect native iOS Swift logic with our React Native and JavaScript/TypeScript ecosystems.

• Legacy Modernization: Strategize and execute the incremental refactoring, modularization, and modernization of our legacy native codebases without interrupting active clinical research studies.

• Release & Infrastructure Ownership: Direct the entire App Store submission pipeline, provisioning profiles, CocoaPods dependency management, and automated Xcode deployment infrastructure.

Required Qualifications

• Expert-Level Native iOS Mastery: Deep professional experience in native iOS application development with a proven track record operating at a Senior, Lead, or Staff level.

• Framework Expertise: Complete mastery of UIKit, Storyboards, Auto Layout, CoreLocation, CoreData, HealthKit, and SensorKit.

• Compliance & Security Rigor: Solid understanding of building apps that strictly comply with HIPAA, GDPR, and SOC 2 Type 2 guidelines (end-to-end encryption at rest and in transit, access control enforcement, and audit logs).

• Cross-Platform Competency: Production-grade architecture experience using JavaScript/TypeScript and React Native to build cross-platform feature parity.

• Language Proficiency: Advanced command of Swift and modern native iOS architectures.

• App Store Pedigree: Complete history of deploying, configuring, and maintaining highly rated commercial apps directly on the Apple App Store.

Preferred Qualifications

• Experience designing flexible engines for complex dynamic forms, custom survey validation logic, or matrix questions.

• Engineering background in health-tech, remote patient monitoring (RPM), or data-intensive research applications.

• Experience building and scaling custom automated build pipelines (Fastlane, Xcode Cloud).

• Understanding of broader cross-platform ecosystems, including Android execution environments.

Why ExpiWell

• Drive the technical vision for technology used globally in critical behavioral and health research.

• Collaborative, research-driven engineering team environment with high technical autonomy.

• Flexible, fully remote working structure within Bangladesh.

• Competitive monthly salary package aligned with the absolute top tier of local senior standards.

• Opportunity to serve as the ultimate technical authority and shape our mobile architecture.

To Apply

Please submit your resume, portfolio/GitHub links of apps you have engineered, and a summary detailing your experience handling native Swift codebases alongside React Native systems and healthcare compliance data structures.

• Job Type: Full-time

• Work Location: Remote (Open to candidates across Bangladesh)
