• Experience deploying and operating services on a major cloud platform (AWS, Google Cloud or Azure).
• Deep understanding of the software development lifecycle and agile methodologies.
• Strong problem-solving skills, self-sufficiency and a proactive “can-do” attitude.
• Fluent English communication skills, both written and verbal.

Nice to Have:

• Experience coordinating with offshore development teams.
• Background in web-based SaaS platforms.
• Exposure to large-scale data processing or Big Data technologies.
