How to Apply for Senior AI Controls Solutions Engineer (Electrical Systems)

at Phaidra

🏢 About Phaidra

Phaidra is a leader in AI-driven control systems for industrial efficiency, focusing on reducing energy waste and environmental impact. Their unique approach combines advanced AI with deep industrial domain expertise to optimize complex systems like data center cooling and power distribution. Working here means contributing to cutting-edge technology that directly addresses climate change.

About This Role

As a Senior AI Controls Solutions Engineer, you will bridge the gap between AI and physical infrastructure by deploying Phaidra's platform on enterprise data center systems. You'll create facility models, map tag data, and ensure AI models run smoothly in production, directly impacting energy savings and operational efficiency. This role is critical for scaling Phaidra's solutions across thousands of customers.

💡 A Day in the Life

A typical day might start with reviewing system health dashboards for deployed AI agents, then collaborating with the product team to define new features based on customer feedback. You might spend the afternoon writing Python scripts to automate tag mapping for a new data center customer, followed by a call with a site engineer to troubleshoot a model anomaly.

🎯 Who Phaidra Is Looking For

  • A controls engineer with 10-15 years of experience in data center power distribution and cooling systems, able to read electrical schematics and understand SCADA/BMS architectures.
  • Proficient in Python scripting for data analysis, automation, and integration with control systems (e.g., writing scripts to map tags or automate model deployment).
  • Hands-on experience with PLC programming (ladder logic, structured text) and familiarity with industrial protocols like Modbus, BACnet, or OPC-UA.
  • Comfortable working in a fast-paced startup environment, collaborating with product teams to translate customer needs into product requirements.

📝 Tips for Applying to Phaidra

1

Tailor your resume to highlight specific data center projects, especially those involving power distribution (PDUs, UPS, switchgear) and cooling (chillers, CRACs).

2

In your cover letter, mention a specific challenge in data center controls (e.g., optimizing PUE) and how your experience addresses it.

3

Showcase your Python skills by linking to a GitHub repo or describing a script you wrote for control system data analysis or automation.

4

Emphasize any experience with AI/ML integration into control systems, even if basic, as Phaidra values bridging AI with industrial controls.

5

Research Phaidra's case studies or blog posts (e.g., on data center efficiency) and reference them in your application to show genuine interest.

✉️ What to Emphasize in Your Cover Letter

["Your deep expertise in data center power distribution and cooling systems, and how it aligns with Phaidra's mission to reduce energy waste.", 'Your ability to work with both hardware (PLCs, sensors) and software (Python, AI platforms) to deploy and maintain control solutions.', "Examples of how you've collaborated with product teams to define requirements or improve customer implementations.", 'Your passion for using AI to solve real-world industrial problems, referencing specific Phaidra technologies or projects.']

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → Read Phaidra's case studies on data center efficiency and their approach to AI-based control (e.g., 'Phaidra for Data Centers').
  • → Study their blog posts or whitepapers on AI in industrial controls to understand their technology stack and value proposition.
  • → Review their leadership team's background (e.g., founders from DeepMind) to understand the company's culture and vision.
  • → Familiarize yourself with their platform's capabilities: how they model facilities, map tags, and deploy AI agents.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Describe a time you mapped a complex data center's power distribution system and integrated it with a control platform. What challenges did you face?
2 How would you troubleshoot a scenario where an AI model recommends a cooling setpoint that conflicts with safety limits?
3 Explain how you would use Python to automate the mapping of thousands of tags from a BMS to Phaidra's schema.
4 What is your experience with PLC programming for data center applications? Walk us through a project involving ladder logic or structured text.
5 How do you stay current with data center industry trends (e.g., ASHRAE standards, liquid cooling)?

⚠️ Common Mistakes to Avoid

  • Downplaying the importance of hands-on controls experience; this role requires deep knowledge of electrical systems and PLCs, not just AI.
  • Submitting a generic cover letter that doesn't mention data centers or Phaidra's specific mission; personalize it.
  • Overemphasizing software engineering skills without demonstrating industrial domain expertise; balance is key.
