• Use a variety of testing methodologies to ensure performance, stability, and reliability in our code and products (unit, integration, cluster, end-to-end, performance, fault tolerance).
• Deploy code to the cloud; learn and use AWS, K8s, CI/CD, Front-end frameworks, and Back-end service building techniques.
• Participate in the refinement of the team’s Product Backlog, estimating work and other Agile ceremonies as a strategic voice to the team.
• Collaborate with cross-functional stakeholders to align goals and deliver high-quality solutions. 
• Foster a positive team environment to promote collective growth. 
• Provide mentorship to junior engineers.
