Job description
The Embedded Software Engineer is responsible for developing and maintaining firmware for SmartRent devices, including Z-Wave controllers (hubs) and access control systems. This role supports the integration of hardware devices with SmartRent platform services, enabling reliable communication between field devices and cloud-based systems.
This role contributes to firmware development using the Nerves framework and Elixir-based systems and collaborates with hardware, platform, and application teams to implement new functionality, support device reliability, and maintain existing device software.
Responsibilities
- Lead medium- to large-scale development efforts across the embedded stack, from firmware through device interfaces, operating with a high degree of autonomy while collaborating with cross-functional teams.
- Design, develop, and maintain firmware for SmartRent IoT devices using Elixir and the Nerves framework.
- Lead the bring-up of new hardware platforms, including driver development, peripheral integration, and system validation.
- Develop and maintain device-local user interfaces running on embedded hardware using technologies such as Phoenix, Flutter, and gRPC.
- Integrate third-party systems, including HVAC, access control, and Z-Wave platforms, by interpreting vendor documentation and supporting required communication protocols.
- Develop and maintain automated tests and supporting documentation to ensure system reliability and prevent regressions across deployed devices.
- Develop project timelines, manage deliverables against defined milestones, and communicate risks, dependencies, and requirement changes proactively.
- Support team development through code reviews, technical guidance, knowledge sharing, and mentorship of less experienced engineers.
- Contribute to internal tooling, shared engineering resources, and open-source initiatives aligned with SmartRent's technical ecosystem.
