Senior Go Engineer – IoT & Energy Integrations (all genders)

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.

**Tech environment:**Go • Linux • Docker • Kubernetes • gRPC • Protocol Buffers • Modbus • EEBUS • OCPP • React/TypeScript • CI/CD • Nix
