How to Apply for Senior Go Engineer – IoT & Energy Integrations (all genders)

at GridX

🏢 About GridX

GridX is at the forefront of the energy transition, building a virtual power plant that integrates millions of distributed energy resources. As a remote-first company with a strong engineering culture, they offer the chance to work on impactful green-tech solutions while shaping AI-assisted workflows.

About This Role

As a Senior Go Engineer, you'll own critical services that connect IoT devices to GridX's platform—polling measurements, sending commands, and handling failures. Your work directly enables a decentralized, intelligent energy grid, with opportunities to evolve the integration framework and mentor peers.

💡 A Day in the Life

Your day might start with a stand-up discussing integration issues with OEM partners, then diving into code to improve mDNS discovery or add a new device profile. After lunch, you could review a colleague's PR on the integration framework, and later brainstorm with the team on how to leverage AI for automated test generation.

🎯 Who GridX Is Looking For

  • Strong Go expertise with a track record of building and maintaining production-grade services, especially in distributed systems.
  • Pragmatic and product-oriented: you balance code quality with speed, and take ownership of end-to-end features.
  • Curious about IoT and energy systems—you're excited to learn about protocols like mTLS, mDNS, and device configurations.
  • Comfortable with remote collaboration and contributing to open-source or internal tooling that other engineers rely on.

📝 Tips for Applying to GridX

1

Tailor your resume to highlight Go projects with IoT or energy themes—mention specific protocols or hardware you've worked with.

2

In your cover letter, explicitly connect your experience with mTLS, mDNS, or similar secure communication protocols.

3

Showcase any open-source contributions or side projects that demonstrate your ownership mentality and product thinking.

4

Mention your familiarity with virtual power plants, energy management, or smart grid concepts to stand out.

5

If you have experience with AI-assisted development tools (e.g., GitHub Copilot, Codex), note how you'd shape workflows at GridX.

✉️ What to Emphasize in Your Cover Letter

['Emphasize your Go system design skills and experience with distributed, fault-tolerant services.', 'Highlight any IoT or embedded systems background, even if from hobby projects or academic work.', "Express genuine interest in the energy transition and how your role contributes to GridX's mission.", 'Demonstrate your pragmatic, ownership-driven approach with a specific example of a project you shipped end-to-end.']

🔍 Research Before Applying

To stand out, make sure you've researched:

  • Read GridX's blog or tech talks about their virtual power plant architecture and IoT integration challenges.
  • Understand the basics of energy markets and how virtual power plants aggregate distributed resources.
  • Familiarize yourself with common IoT protocols (MQTT, CoAP, OPC UA) and how they differ in energy contexts.
  • Check GridX's GitHub for open-source projects or libraries they maintain—contribute a small fix or issue.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Design a Go service that polls thousands of IoT devices, handles timeouts, and retries with exponential backoff.
2 How would you implement mTLS for secure device-to-cloud communication? Walk through certificate management.
3 Describe a time you had to balance feature velocity with code quality—what trade-offs did you make?
4 Explain how you'd approach debugging a flaky integration with an OEM device that intermittently drops connections.
5 How would you contribute to an integration framework used by both internal teams and external partners?

⚠️ Common Mistakes to Avoid

  • Avoid generic applications—don't just list Go experience without connecting it to IoT or energy.
  • Don't overlook the 'ownership mentality' requirement; avoid answers that shift responsibility to others.
  • Don't underestimate the distributed systems aspect—prepare for system design questions, not just coding puzzles.
