Job Description
About the role
\n
EHMA builds the software behind Everpower’s family of products. We’re looking for an embedded Android engineer who can work the full stack — from the Android platform (AOSP) up to user-facing applications — on our purpose-built, accessibility-focused, purpose-built tablet and connected-device hardware. You’ll own the device software end to end: bringing up and customizing the platform, integrating hardware, and building the reliable, kiosk-grade apps people depend on every day. You’ll work on a small, fast-moving team alongside our backend engineers, and contribute to other Android/mobile work across our products as priorities evolve.
\n
\n
What you'll do
\n
• Build and customize the Android platform (AOSP) for our purpose-built tablet hardware — board bring-up, system integration, and platform services.
\n
• Build and maintain the on-device applications, including accessibility-first experiences.
\n
• Integrate with device hardware at a low level and deliver kiosk-grade reliability — lockdown, crash resilience, safe recovery for long-running unattended use.
\n
• Work with the backend team on device provisioning, over-the-air updates, remote configuration, and telemetry.
\n
• Protect proprietary on-device inference code — run sensitive logic in a hardware-backed secure environment (Android Keystore / StrongBox, Trusted Execution Environment) so it resists reverse engineering and tampering.
\n
• Contribute to other Android and mobile initiatives across our product portfolio as needs shift.
\n
\n
Where you’ll make an impact early
\n
• Shipping production platform + application builds for our device.
\n
• Establishing reliable bring-up, update, and provisioning flows with the backend team.
\n
\n
What we're looking for
\n
• Embedded development experience, able to work the full stack — from the Android platform up to user-facing applications.
\n
• Hands-on experience building AOSP (Android Open Source Project) — customizing and building the Android platform, not just apps.
\n
• Strong C++ and Java; familiarity with Kotlin.
\n
• Experience building for physical / embedded devices and delivering kiosk-grade reliability.
\n
• Familiarity with device-management concepts — provisioning, OTA updates, remote config.
\n
\n
Nice to have
\n
• Low-level hardware interaction — GPIO, MIPI, UART.
\n
• GMS (Google Mobile Services) certification experience.
\n
• Experience taking a product from birth to launch (0-to-1 / new-product development).
\n
• Residential energy industry experience.
\n
• Accessibility engineering — assistive technology and alternative input.
\n
• Hardware-backed security and on-device model protection (Keystore / StrongBox, TEE, anti-tamper).
\n
- \n
- Regulated or medical-device software experience.
