at Critical Loop

🏢 About Critical Loop

Critical Loop is at the forefront of the energy transition, combining cutting-edge energy storage technology with intelligent control software to make power more accessible and efficient. Working here means contributing to a mission-driven team that values innovation and sustainability in a fully remote, collaborative environment.

About This Role

As a Software Engineer on the data infrastructure team, you'll own the telemetry data pipeline that powers real-time monitoring and analytics for a growing fleet of energy storage assets. Your work directly impacts the reliability and performance of deployed systems, enabling predictive maintenance and operational optimization.

💡 A Day in the Life

Your day might start by reviewing pipeline health dashboards and investigating any data gaps from overnight. You'll then collaborate with the operations team to build a new analytics workflow for predictive maintenance, and end the day documenting a data model change that improves query performance for site reliability engineers.

🎯 Who Critical Loop Is Looking For

  • Has deep experience with SQL and data modeling, and has built production data pipelines using Airflow, Prefect, or Dagster.
  • Thrives in a production data environment, comfortable with cloud infrastructure, Linux, logs, APIs, and observability tradeoffs.
  • Has built internal data tools or dashboards that are actively used by stakeholders, with a focus on user needs.
  • Excels at documentation and communication, able to explain complex data issues to cross-functional teams.

📝 Tips for Applying to Critical Loop

1

Highlight specific projects where you scaled data infrastructure for IoT or device fleets, emphasizing reliability and query performance.

2

Showcase your experience with energy or industrial data, even if from a different domain, to demonstrate domain adaptability.

3

Include examples of dashboards or tools you built that had measurable impact on operations or decision-making.

4

Mention your familiarity with state machine behavior or dispatch optimization, as these are key to the role.

5

Tailor your resume to emphasize production data environment skills, not just academic or hobby projects.

✉️ What to Emphasize in Your Cover Letter

['Your passion for using data to solve real-world energy challenges and improve grid reliability.', 'Proven track record of building scalable data pipelines and tools that stakeholders love.', 'Ability to work autonomously in a remote environment while maintaining clear communication.', "Specific experience with telemetry or asset monitoring that aligns with Critical Loop's mission."]

⚠️ Common Mistakes to Avoid

  • Submitting a generic application that doesn't reference energy or telemetry data.
  • Overemphasizing frontend or mobile experience without connecting it to data infrastructure.
  • Neglecting to mention remote work experience or self-discipline, as the role is fully remote.
