Newfire is seeking a  Senior Android System Engineer

What's the Project?
Joining the team that is building a high-impact clinical software solution designed to modernize real-time communication within busy healthcare environments. Developed as a high-performance interactive application for large-format displays, it replaces traditional dry-erase boards with dynamic, centralized patient data, shift schedules, and key operational insights - running on custom Android devices we build, sign, and manage ourselves. Candidates joining this project will tackle exciting engineering challenges at the intersection of custom AOSP builds, robust device-level integration, and over-the-air fleet management, collaborating closely with hardware/device partners to deliver the privileged, system-level capabilities the application depends on across a fleet of specialized display units.

Your day-to-day activities:

• Build, sign, and maintain custom AOSP images; write patches (e.g., to mainline modules such as NetworkStack) and apply them to the OEM's RK-class tree
• Implement privileged, system-level capabilities: OTA apply via update_engine, remote reset, system log capture, input injection/screen capture, and device identity (mTLS / hardware attestation)
• Evaluate technical tradeoffs (e.g., Privileged App vs. Device Owner strategies, capture/injection approaches) and prototype solutions to inform core roadmap decisions
• Collaborate with hardware partners to implement device-level capabilities, privileged app permissions, and custom OS integrations; verify behavior on real devices
• Help maintain the Kotlin on-device agent and its integration with the MDM and our OTA / remote-management backend
• Participate in active sprint ceremonies, engage in peer code reviews, and work closely with product management and client engineering leads to execute on parallel technical tracks

You’re a perfect match if you have:

• Hands-on experience building and modifying custom Android builds (AOSP) - Soong/Make, platform/AVB/OTA key signing, custom system images, and applying patches to a vendor BSP tree (Rockchip / RK-class SoCs a plus)
• Deep privileged / system-app experience: platform-signed apps, @SystemApi/hidden-API usage, SELinux/sepolicy, Device Owner and Device Policy Manager APIs, and the trade-offs between them
• OTA / firmware update experience: update_engine and A/B (Virtual A/B), AVB, OTA packaging and signing (ota_from_target_files), and rollback behavior
• System-level Android capabilities: remote factory reset, system-level log capture, input injection, screen capture, adbd, and OS-level networking (e.g. DHCP client behavior)
• Proven capability interfacing directly with device OEMs/manufacturers to debug SDKs, system permissions, and hardware-software integration constraints, with a verify-on-device-first instinct
• Track record of driving technical research spikes - evaluating low-level architectural tradeoffs (e.g. Privileged App vs. Device Owner, capture/injection mechanisms) and presenting clear recommendations to stakeholders 
• MDM & Fleet Management: experience integrating with a third-party MDM and/or building enrollment, remote-management, and OTA workflows for managed hardware fleets
• Clear, confident verbal and written communication skills to collaborate directly with cross-functional product, application, and OEM stakeholders
• As a Senior team member, you will be expected to actively participate in our hiring processes by serving on interview panels for future roles across the company

Nice to have:

• Healthcare Domain Knowledge: familiarity with clinical environments, EHR integrations, or healthcare compliance standards (HIPAA)
• C/C++ / native, kernel, or U-Boot familiarity
• Strong understanding of REST architecture and OOP principles/design

Please note that employment will be contingent upon providing documentation verifying your legal work authorization in the country of residence, in accordance with applicable law.
