• 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.

Required Qualifications

• Proficiency in Elixir or Erlang/OTP, with working knowledge of the BEAM runtime, or demonstrated ability to learn and apply functional programming concepts.
• Experience with, or demonstrated interest in, embedded Linux systems development.
• Working knowledge of Linux internals, including device trees, kernel configuration, system boot processes, and shell tooling.
• Demonstrated ability to deliver projects from design through deployment with minimal supervision.
• Strong written and verbal communication skills, with the ability to collaborate effectively across teams.
• Demonstrated ability to learn and apply new tools, languages, and technologies as required.
• Must be authorized to work in the United States without the need for employer sponsorship now or in the future.

Preferred Qualifications

• Experience with the Nerves framework or embedded Elixir development.
• Experience with Phoenix, LiveView, or other Elixir-based web frameworks.
• Working knowledge of C/C++ for hardware-adjacent development or driver support.
• Familiarity with IoT communication protocols, such as MQTT, Z-Wave, or BLE.
• Exposure to HVAC or building automation systems.
• Experience integrating access control systems or similar hardware-based platforms.
• Ability to read and interpret hardware datasheets and schematics at a foundational level.
• Experience contributing to open-source projects or shared technical libraries.
