How to Apply for Senior AI Research Scientist (Model-based RL)

at Phaidra

🏢 About Phaidra

Phaidra stands out for its mission-driven focus on using AI to drastically reduce industrial energy waste and environmental impact, while also offering a fully remote, collaborative culture. The company applies cutting-edge AI research directly to real-world industrial control systems, making a tangible difference in sustainability.

About This Role

As a Senior AI Research Scientist, you will lead the development of model-based RL agents that control industrial systems, directly impacting energy efficiency. Your work involves designing planning-based controllers, building world models, and ensuring safe deployment, bridging the gap between research and practical impact.

💡 A Day in the Life

A typical day might start with a stand-up with your research team to discuss progress on world model training, followed by coding a new planning algorithm in Python. After lunch, you might mentor a junior researcher on sim-to-real transfer, then analyze experimental results from a deployed controller on a real industrial plant, iterating on safety constraints.

🎯 Who Phaidra Is Looking For

  • Deep expertise in model-based RL, including planning algorithms like MPC or MPPI, with a strong publication record in top venues (NeurIPS, ICML, CoRL).
  • Hands-on experience closing the sim-to-real gap, e.g., deploying RL agents on physical systems or working with industrial simulators.
  • Solid understanding of safe RL and constrained control, with practical experience implementing safety constraints.
  • Proven ability to mentor junior researchers and translate complex research into deployable solutions.

📝 Tips for Applying to Phaidra

1

Highlight specific projects where you designed and deployed model-based RL agents on real hardware, not just simulations.

2

Emphasize any experience with industrial control systems (e.g., HVAC, data centers) or related domains like robotics.

3

Showcase your work on safety and constraints, e.g., papers on safe RL or constrained MDPs.

4

Tailor your CV to include metrics: energy savings, sample efficiency, or deployment success rates.

5

Mention familiarity with Phaidra's technology stack (e.g., Python, TensorFlow/PyTorch, ROS) and industrial protocols.

✉️ What to Emphasize in Your Cover Letter

['Your passion for using AI to tackle climate change and industrial efficiency.', "Specific examples of model-based RL projects you've led, especially those with real-world deployment.", "Your experience with safe RL and how you've ensured reliability in autonomous systems.", "Why Phaidra's mission and remote culture align with your career goals."]

🔍 Research Before Applying

To stand out, make sure you've researched:

  • Read Phaidra's blog posts and case studies on their AI control systems for industrial plants.
  • Review recent papers from Phaidra's research team (e.g., on model-based RL or safe control).
  • Understand the industrial domains Phaidra targets (e.g., data centers, steel plants) and their specific challenges.
  • Familiarize yourself with the company's values: remote-first, interdisciplinary collaboration, and environmental impact.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Describe a model-based RL project where you had to close the sim-to-real gap. What challenges did you face and how did you overcome them?
2 How would you design a safe exploration strategy for an industrial cooling system with hard constraints?
3 Explain your approach to training a world model that is both accurate and computationally efficient for real-time MPC.
4 How do you stay updated on the latest RL research, and how would you decide which new methods to integrate into Phaidra's stack?
5 Walk us through a time you mentored a junior researcher. How did you help them grow?

⚠️ Common Mistakes to Avoid

  • Overemphasizing model-free RL or deep learning without connecting to model-based control or planning.
  • Lack of concrete examples of real-world deployment; avoid purely theoretical work.
  • Ignoring safety and constraints; this role is critical for industrial applications where failures are costly.
