Job description

Technology that speaks your language

Domera Labs builds Ami, the first AI companion for seniors. Ami brings the power of a smartphone into a more human form: voice-first and deeply personalized We at Domera Labs are rethinking human-machine interaction from first principles by introducing a better interface to interact with technology: voice By combining the most intuitive hardware design with frontier AI, Ami makes AI accessible for the fastest growing demographic worldwide. The goal is to make the everyday life older adults more seamless, while addressing that generation's biggest challenge: loneliness and isolation. With Ami we are building the category leader of a new hardware paradigm by building a full standalone device (and not a gadget) that aims to makes the smartphones of today redundant. The underlying technology of Ami combines a model-agnostic streaming pipeline consisting of proprietary models and off-the-shelf frontier models to create a hyper-personalized and proactive user experience. The backbone of Ami is built by our foundational lab that builds a social intelligence model that is optimized for social interaction, human behavior and interpersonal skills. Domera Labs has secured large distribution agreements, a model co-development partnership with a leading AI lab, and ODM manufacturing proposals. We are looking for people who want to build at the intersection of human-machine interaction, mass-consumer facing hardware and shape frontier research with social/non-quantifiable benchmarking.

Core Responsibilities

You own the software that makes Ami work. Your primary responsibility is to architect, write and ship the on-device application and services for our mass-market consumer device, from voice interaction and cloud connectivity to onboarding, recovery and everyday reliability. You will work directly with our ODM and silicon partners to integrate that software with the underlying platform.

Our target hardware uses a Qualcomm SoC with Android/AOSP or embedded Linux depending on the final platform selection.

Our users are 75 years old and there is no screen, no settings menu, and no IT support. If the device does not work out of the box, it fails. Your job is to make the following work.

• On-device application: build and own Ami's application and services, including interaction logic, real-time audio streaming, cloud communication, local state and recovery from network interruptions or service failures

• Device identity and fleet management: provisioning, unique device identity, secure key storage, and the systems that let us know what every unit in the field is doing

• The maintenance channel: a reliable service and diagnostics path to the device (BLE, USB-C, or both) for field debugging, factory test, and recovery

• Out-of-the-box experience: first-boot network onboarding that a senior can complete alone, with no screen and no smartphone as a crutch. This is the single highest-stakes piece of the product

• Flash and update management: partition layout, A/B OTA with rollback, staged fleet rollouts, and bricking as a category of bug that never happens

• Base platform behaviors: boot and recovery, factory and soft resets, button and LED mappings, audio feedback, power states and battery behavior

• The audio front end: working with our ODM and silicon partners on mic array, echo cancellation, wake word, and the latency budget from mic to first spoken token

• Bringing the device through EVT, DVT, and PVT with our ODM as the technical counterpart on our side

What we are looking for

• A builder's mindset: ship > fail > learn > improve

• Stay focused when multiple priorities compete and the ranking is unclear

• Work seamlessly across research and engineering

• Can navigate ambiguity and make progress in fast-moving research environments

• This is a founding-level position. You will work directly with the founders, shape the architecture from the ground up, and see your work in users' hands within months, not years.

Technical Requirements

• You have shipped a connected consumer device to production, not just to a demo table. You know what goes wrong between DVT and mass production

• Strong hands-on experience building production device applications and services on Android/AOSP, using Kotlin or Java and C/C++ for native components and hardware integration. You can own the on-device application end to end, including background execution, connectivity, audio and integration with platform services. Experience with embedded Linux is a plus; Python proficiency for tooling and testing is expected.

• Experience developing for AOSP-based devices beyond standard smartphone apps: integrating privileged applications and services, working with system permissions and hardware interfaces, and collaborating with an ODM or silicon vendor on the underlying platform. Qualcomm platform experience is a plus.

• Wireless connectivity in the real world: Wi-Fi provisioning, BLE, and ideally cellular. You have debugged a device that would not join a network in someone's home

• OTA and flash: bootloaders, secure boot, A/B partitioning, rollback, and staged rollouts across a fleet

• You can diagnose issues across application code, platform services and hardware interfaces

• A builder's mindset: you'd rather ship and measure than debate

• Bonus: real-time audio pipelines (I2S, DSP, AEC, wake word), on-device ML inference, factory test and manufacturing line bring-up, regulatory certification (CE, FCC), power optimization for battery life, experience in NLU / NLP

We lean toward senior engineers who can independently own production device software, but demonstrated ownership matters more than years of experience. Experience integrating real-time AI services into a consumer product is a plus.

What you get

• Founding-team equity and a real say in technical direction

• A product with signed launch partners, not a demo in search of a market

• A small team, short decision paths

• Cash compensation range of CHF 80 - 100k with significant equity incentives

• Opportunity to shape the future of hardware and social intelligent AI models

We encourage you to apply even if you do not believe you meet every single qualification.
