How you can contribute to gridX
Build the integration layer behind a distributed energy platform.
At gridX we're building the software infrastructure that connects real-world energy hardware, batteries, inverters, EV chargers, heat pumps, and smart meters, into one unified energy ecosystem.
As a Senior Go Engineer, you'll develop the systems that allow thousands of devices from dozens of manufacturers to communicate reliably with our platform in real-world environments. This is not typical backend CRUD development. Your software runs on Linux-based IoT gateways at the edge, communicates via protocols like Modbus, REST, EEBUS, and OCPP, connects to the cloud through HTTP and gRPC, and translates hardware-specific protocols into a unified data model.
What you'll work on
- Device integrations: Build and maintain Go services that poll measurements, send control commands, and handle communication failures, retries, and recovery flows across real hardware environments.
- Integration framework: Help evolve our next-generation integration stack with mTLS security, mDNS discovery, and declarative device configurations, while migrating existing drivers into the new architecture.
- Tooling & ecosystem: Contribute to internal validation tooling and integration frameworks used by both gridX engineers and external OEM partners to develop and verify device integrations.
- AI-assisted engineering: We actively use AI-assisted and agentic coding workflows across implementation, testing, code review, and specification analysis. You'll help shape how these workflows evolve within the team.
Day-to-day, that means
- Implementing integrations based on datasheets and protocol specifications
- Designing resilient systems for unreliable communication and real-world timing constraints
- Migrating imperative drivers into declarative integration models
- Debugging low-level communication issues using tools like tcpdump and register dumps
- Contributing to protocol specifications, tooling, and integration architecture
- Collaborating closely with firmware teams, hardware manufacturers, partners, and domain experts
- Mentoring teammates and contributing to technical direction across teams
This is how you and your application stand out
What matters beyond code
- Pragmatism over perfection: You focus on delivering robust solutions, iterating quickly, and avoiding unnecessary complexity.
- Ownership: You take responsibility beyond implementation — from architecture and debugging to operational reliability in the field.
- Product thinking: You care about the impact your work has on users, partners, and the broader energy ecosystem.
- Curiosity for the domain: You're excited by complex systems, connected hardware, and renewable energy technology.
- Engineering excellence: You write maintainable Go code, think deeply about system design, and enjoy improving tooling, architecture, and developer experience.
