How to Apply for AI Engineer

at Charge Point

🏢 About Charge Point

ChargePoint is the world's largest open EV charging network, powering the transition to electric mobility for millions of drivers globally. Working here means being at the forefront of sustainable transportation, where your AI solutions directly impact the reliability and accessibility of EV charging infrastructure.

About This Role

As an AI Engineer at ChargePoint, you'll lead the development of production-grade AI systems across Voice AI, Computer Vision, and Conversational AI to enhance monitoring, customer support, and automation for EV charging. Your work will directly improve experiences for millions of EV drivers and operators worldwide.

💡 A Day in the Life

Your day might start with a stand-up to align with cross-functional teams on AI features for the charging platform. You'll then dive into coding a LangChain pipeline for a new conversational AI feature, followed by a review of Elasticsearch query performance for semantic retrieval. After lunch, you could pair with a data engineer on a computer vision model for station health monitoring, then wrap up by drafting an architecture doc for a Voice AI prototype.

  • → Explore the company's sustainability reports and understand how AI contributes to their net-zero goals.
  • → Check out ChargePoint's developer API documentation to understand the data and integration points for AI solutions.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Design a RAG system for a customer support chatbot that handles EV charging issues; discuss retrieval strategy and latency optimization.
2 How would you use computer vision to monitor charging station status or detect faults from camera feeds?
3 Describe a complex AI system you deployed; walk through architecture, challenges, and how you ensured production reliability.
4 How do you approach prompt engineering for a Voice AI assistant that must handle diverse user intents?
5 Explain how you would use Elasticsearch for hybrid search in a semantic retrieval pipeline for EV driver queries.

⚠️ Common Mistakes to Avoid

  • Don't focus solely on academic research or non-production ML; emphasize production deployments and scaling.
  • Avoid generic AI buzzwords without specific examples of how you've used LangChain, vector databases, or similar tools.
  • Don't neglect the domain: failing to mention EV charging or IoT infrastructure experience may make you seem less aligned.
