About GridPoint
GridPoint is a private equity backed technology leader with a mission to accelerate the world's transition to a sustainable future by creating an intelligent energy network of grid-interactive buildings. Our technology platform harnesses the power and potential within a building to deliver energy, operational, and resiliency benefits — spanning Fortune 500 enterprises, utilities, government organizations, and small businesses.
About the Role
GridPoint is hiring a Software Engineer II for the Application Firmware team. You will work in Elixir on the firmware running our in-building energy controllers, the layer between our bare-metal firmware and the GridPoint cloud.
The work varies. A device-side control feature one month, a telemetry pipeline the next, a field failure after that. The target does not vary: constrained hardware installed incustomer buildings, where memory, CPU, and network are all finite.
Responsibilities
- 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
Qualifications
Required
- 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
Preferred
- 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
What Success Looks Like
Level II is where an engineer delivers a feature end to end without close supervision. The first year should look roughly like this.
Milestone What we expect
3 months Shipping scoped features through normal review; at home in the codebase and on bench hardware
6 momths Owning a feature area from design through field validation; taking part in release validation and triage
12 months Turning vague requests into designs the team agrees on; mentoring newer engineers; trusted to judge release risk
Annual Salary Range: $135,000 to $175,000
