  • Deep comfort and practical experience with containers and orchestration technologies, specifically OpenShift
  • Demonstrated ability to architect, develop, and deploy highly performant, large-scale AI/ML systems into production environments
  • Strong understanding of modern software development principles, clean code practices, data structures, algorithms, and distributed systems
  • Proficiency with Relational (preferably, PostgreSQL) and Vector (preferably, pgvector) databases

Nice to have:

  • Proficiency in additional programming languages such as Java, JavaScript/TypeScript, or Golang
  • Experience with specific frameworks like Spring (AI, Boot), N8N, or Flask
  • Familiarity with messaging and integration platforms such as Kafka or JMS/MQ
  • Experience with UI development using modern frameworks like React JS or StreamLit for interactive AI applications
  • Practical experience in model risk management, developing AI guardrails, and establishing end-user adoption pathways for Generative AI solutions
  • A proven track record of contributing to open-source projects or publishing relevant research in AI/ML
What we offer:
  • Unprecedented Impact & Visibility: Contribute to critical, high-visibility projects that are transforming a global enterprise
  • Cutting-Edge Technology: Work with the latest Generative AI models, agentic frameworks, and cloud-native technologies, enhanced by access to AI-assisted development tools like Devin and Copilot
