Mobile System Architect (IRC283197)

You will define and oversee the technical architecture of a security-critical Android gateway application that communicates with wearable cardiac monitoring devices for a major U.S. healthcare provider.
Your role combines solution design, architectural governance, cross-team collaboration, and deep Android expertise — including BLE communication, secure data flows, background reliability, and MDM/enterprise constraints.

You will work closely with product, firmware, backend, and security teams to ensure that the mobile gateway is robust, compliant with medical-grade standards, scalable, and maintainable for long-term product evolution.

Job Description

• 8–10+ years of experience in Android development, including deep expertise with Kotlin.
• Strong experience designing and implementing complex mobile architectures (MVVM + coroutines + flows + modularization).
• In-depth understanding of BLE communication patterns (GATT, characteristics, data exchange strategies, reconnection logic).
• Advanced knowledge of background work management: WorkManager, foreground services, and reliability strategies.
• Experience designing secure mobile systems: encrypted storage, key management, TLS, certificate pinning.
• Strong exposure to enterprise environments: MDM/Device Owner mode, kiosk mode, device restrictions.
• Ability to create architecture diagrams and documentation using UML 2.0 or similar standards.
• Solid understanding of cloud-integrated mobile solutions.
• Practical experience building system-level integrations with backend and firmware components.

Nice-to-Have

• Experience in regulated industries (healthcare, medical devices, FDA-aligned workflows).
• Knowledge of IoT ecosystems, firmware protocols, FOTA workflows.
• Experience with cross-platform or multi-client architectures (iOS, React Native, Flutter).
• Performance profiling, stability engineering, and system-level debugging.
• Understanding of database schemas (SQL/NoSQL) at architectural level.
• Hands-on familiarity with CI/CD concepts (Jenkins, GitHub Actions, automated pipelines).
   

Job Responsibilities

•  Define the end-to-end architecture for the Android gateway application, covering BLE, secure data flows, background processing, and MDM/Device Owner policies.
• Translate customer business needs and system requirements into technical solution designs, architectural diagrams, and implementation strategies.
• Shape the BLE system design (connection strategy, retries, data protocol, reliability constraints) and ensure its alignment with the overall ecosystem (patch ↔ gateway ↔ backend).
• Establish security principles for data at rest/in transit, encrypted communication channels, secure storage, and certificate pinning.
• Provide architectural oversight during development, ensuring adherence to best practices, design patterns, and regulatory constraints (HIPAA-aligned workflows, auditability, logging).
• Review and approve technical designs, API contracts, BLE protocol changes, and background processing strategies.
• Lead technical discussions with internal and external stakeholders; evaluate trade-offs and propose optimal solutions.
• Guide senior and lead engineers, enabling consistent architecture execution across the team.
• Support estimation, feasibility analysis, risk assessments, and system-level debugging.
• Drive innovation by evaluating emerging Android, BLE, IoT, and MDM technologies and identifying opportunities for improvement.
