Contribute to objectives by identifying and executing cost optimizations (runtime, pipeline, infra), and quantifying savings.
Collaborate with product, design, platform, security, and data teams to translate business needs into scalable, secure, maintainable solutions.
Create and socialize technical designs, playbooks, and runbooks; lead knowledge-sharing to raise the bar across teams.
Implement robust CI/CD pipelines (e.g., GitHub Actions) with quality gates, automated testing, and secure supply chain practices.
Embed observability (logs, metrics, traces, dashboards, alerts) to enable data-driven decisions and fast incident response.
Uphold security and compliance standards (OWASP, secrets management, least privilege, threat modeling); participate in on-call/incident response as needed.
Working model:
At Liberty, we help our customers embrace today and confidently pursue tomorrow by developing online products and services that suit their needs, building trust and loyalty, and providing an exceptional experience.
Our team is very collaborative. When presented with a challenge, we may not know immediately how we will surmount it, but we do know that we can come together as a group and, with our combined skills and experiences, we can rise to any challenge.
