Software Engineer II
Summary
GridPoint is hiring a remote Software Engineer II to build Elixir application firmware for in-building energy controllers — writing device control logic, telemetry pipelines, and cloud sync within tight memory/CPU limits, and debugging on real hardware. Core stack: Elixir/OTP with embedded systems work; Nerves, C/C++, and IoT protocols preferred.
- Build and maintain features in our Elixir application firmware, from story to release
- Structure application services as OTP supervision trees with isolated, restartableprocesses
- Define and implement device control logic, scheduling, local data collection, andconfiguration
- Develop solutions that function within the memory, CPU, and storage limits of thetarget hardware
- Debug on real hardware: bench units, serial consoles, and logs from the field
- Maintain the interfaces to the GridPoint cloud for telemetry, control, and config sync
- Verify your own work on hardware before calling it ready to ship
- Work with stakeholders to define test plans and develop them alongside the solution
- Work with the Bare-Metal Firmware and Hardware teams on drivers, bring-up, andpower behavior
- Bachelor's in Computer Science, Computer Engineering, Electrical Engineering, orequivalent experience
- 2–5 years of professional software engineering experience
- Elixir, or strong functional programming experience and a record of picking up newlanguages
- Understanding of concurrent, fault-tolerant design: processes, message passing,supervision
- Enough embedded or systems background to design within hardware limits
- Comfortable debugging on physical devices, not only locally
- Git-based development and code review
- Production Elixir and OTP; Nerves or similar
- Enough C/C++ to read embedded firmware and work with the bare-metal team
- Device telemetry, OTA update, or fleet management
- MQTT, Wi-Fi, cellular, or LoRaWAN
- Control protocols such as Modbus and BACnet, over both serial and TCP
- Energy management, building automation, HVAC controls, or commercial IoT
- Working alongside hardware and QA through bring-up and validation
