• Team Collaboration: Work closely with product, security, and infrastructure teams on container orchestration solutions that align with company goals and customer needs.
• Challenging Problems: Build backwards compatible solutions to complex problems while optimizing services to run efficiently and troubleshooting when deployments fail.
• Drive Innovation: Constantly seek opportunities to improve automation, testing, and deployment processes.
