  • You are an energized problem-solver who actively seeks out tough technical challenges to deliver maximum business impact.
  • You are a high-trust collaborator who fosters an open challenge culture through constructive candor, mutual respect, and dedication to team success.
  • You embody a true growth mindset, continuously seeking self-development and active feedback to become a stronger partner and teammate.

What We’re Looking for (Minimum Qualifications)

  • Foundational understanding of AI/ML technologies and experience leveraging, securing, or positioning AI-driven solutions to optimize outcomes within your functional domain
  • 7+ years of experience in C programming with a strong understanding of its core principles and performance optimization
  • Hands-on experience with Python and/or Shell scripting for automation tasks to improve workflow efficiency
  • Solid knowledge of Linux/FreeBSD-based operating systems, including process management, threading, memory management, and networking
  • Proficiency in working with AWS, Azure, and GCP, including tasks like creating VM images, exporting them, and maintaining infrastructure
  • Proficiency in designing and maintaining distributed systems, with hands-on experience building, testing, and deploying via Jenkins pipelines

What Will Make You Stand Out (Preferred Qualifications)

  • Proven ability to leverage AI technologies and workflows to drive measurable operational efficiency
  • Knowledge of networking concepts and protocols, with hands-on experience translating them into system-level solutions
  • Hands-on experience with database internals, tuning, and optimization
