How to Apply for Senior Software Engineer, Infrastructure

at Voltus

🏢 About Voltus

Voltus is at the forefront of the energy transition, building the distributed energy platform that connects any distributed energy resource to energy markets across the US and Canada. Their remote-first culture and mission-driven team make it a unique place to work where your technical skills directly combat climate change.

About This Role

As a Senior Software Engineer on Infrastructure, you'll own critical pieces of the core platform that every Voltus engineer and dispatch-critical system depends on. You'll mentor other engineers and set technical direction for building, deploying, and operating services, directly impacting the reliability and scalability of the clean energy grid.

💡 A Day in the Life

A typical day might involve reviewing pull requests for infrastructure code, collaborating with engineers to troubleshoot production issues, and working on automating deployment pipelines. You'll also spend time mentoring junior engineers and participating in design discussions for new features that require scalable backend support.

🎯 Who Voltus Is Looking For

  • Experienced with infrastructure as code (e.g., Terraform, CloudFormation) and container orchestration (e.g., Kubernetes, ECS).
  • Strong background in CI/CD pipelines and developer tooling to improve engineering productivity.
  • Proficient in at least one programming language (e.g., Python, Go, Ruby) and comfortable with scripting for automation.
  • Demonstrated ability to mentor junior engineers and drive technical decisions in a collaborative environment.

📝 Tips for Applying to Voltus
