• Ensure operational readiness of the services and meet the availability and performance SLA commitments to our customers
• A strategic engineer who constantly thinks of process and operational improvements

Required technical and professional expertise

• Demonstrated experience designing, building, scaling and supporting backend systems in production with a solid grasp on good software engineering practices such as code reviews, deep focus on quality, and documentation.
• Strong programming and algorithmic skills. Proficiency in a major programming language, e.g. Java, Go, C / C++, Python, etc.
• Experience configuring and deploying distributed systems and microservices using modern tools, e.g. Kubernetes, Helm, etc.
• Strong focus on project delivery and communication skills.
• Experience in driving operational excellence for large, production services.
• A strong sense of customer centricity, teamwork, technical leadership and mentorship and are excited about team and company success.
• BS, MS, or PhD in computer science or a related field, or equivalent work experience.
