• 3+ year experience with data structures, algorithm design, problem solving, and complexity analysis


• Graduate degree (MS or PhD) in Electrical Engineering, Computer Sciences, Mathematics, or related technical field
• Experience developing cloud software services and an understanding of design for scalability, performance and reliability
• Experience defining system architectures and exploring technical feasibility trade-offs
• Experience optimizing for short term execution while planning for long term technical capabilities
• Ability to prototype and evaluate applications and interaction methodologies
• Ability to produce code that is fault-tolerant, efficient, and maintainable
• Academic and/or industry experience with standard AI and ML techniques, NLU and scientific thinking
• Experience working effectively with science, data processing, and software engineering teams
