Job description

Scion Staffing has been engaged to conduct a search for a Senior Mobile Application Engineer for an innovative early-stage digital health company developing connected technology to improve pediatric care and family health outcomes. This is a remote three-month contract that may have the potential for contract-to-hire. Must be located in the US.

POSITION OVERVIEW

The Senior Mobile Application Engineer will lead the development of a parent- and caregiver-facing mobile application for a connected pediatric health device. This hands‑on engineer will transform established designs and product requirements into a secure, testable, and release‑ready MVP while collaborating with design, hardware, and firmware partners. The ideal candidate is comfortable taking ownership, communicating potential risks early, and delivering reliable software within a fast‑moving startup environment.

PERKS

Meaningful opportunity to build technology that supports children, caregivers, and improved health outcomes. High‑impact role with ownership of the mobile application from development through release. Collaborative remote environment working with experienced healthcare, engineering, design, and product professionals. Competitive compensation aligned with the candidate’s experience and the specialized nature of the engagement.

RESPONSIBILITIES

• Design, build, test, and prepare for release a caregiver‑facing iOS and/or Android application that communicates with a Bluetooth Low Energy‑enabled health device.
• Develop reliable device discovery, pairing, connection, reconnection, data synchronization, and recovery functionality while maintaining separation between the mobile application and device‑communication layers.
• Implement session tracking, adherence calculations, secure data handling, data exports, and easy‑to‑understand progress views using established Figma designs.
• Collaborate with design, product, hardware, and firmware partners to define, test, and troubleshoot the application interface and device‑data protocol.
• Establish automated and manual testing for connection interruptions, synchronization failures, application‑state recovery, security, privacy, and other connected‑device scenarios.
• Manage mobile builds and applicable app‑store submissions while creating clear requirements, architecture, testing, and development documentation to support future regulated‑development activities.

QUALIFICATIONS

• Bachelor’s degree in Computer Science, Engineering, or a related technical field, or equivalent professional experience.
• Minimum of five years of professional software‑development experience, including end‑to‑end ownership of mobile applications that have been successfully released / shipped.
• Strong hands‑on experience building and releasing mobile applications using React Native, Flutter, native iOS/Swift, or native Android/Kotlin.
• Hands‑on experience integrating mobile applications with Bluetooth Low Energy peripherals, including GATT communication, pairing, reconnection, and synchronization of live and stored data.
• Professional experience in healthcare, digital health, connected health, medical technology, or another environment involving sensitive health‑related information.
• Experience working from Figma designs and implementing secure data management, application testing, debugging, release builds, and app‑store submission processes.
• Ability to work independently and collaboratively in a startup environment, communicate effectively across technical and nontechnical teams, and deliver production‑quality software within a defined timeline; familiarity with HIPAA considerations, IEC 62304, design controls, or regulated software documentation is a plus.

COMPENSATION AND BENEFITS

This position offers a competitive hourly rate up to $100/hr (DOE).
