• Practical understanding of containerization frameworks (such as Kubernetes) in hybrid or public cloud settings.
• Familiarity with building and maintaining continuous integration and deployment (CI/CD) pipelines (e.g., GitHub Actions, GitLab CI, Jenkins).
• Strong foundational knowledge of TCP/IP networking concepts (DNS, Routing, VPNs) and enterprise storage solutions (NFS, block, object).
• Excellent collaborative communication skills with a track record of thorough technical documentation.

Preferred Qualifications (Nice-to-Have)

• Hands-on expertise with major cloud platforms (AWS or Google Cloud Platform / GCP).
• Familiarity with managed container orchestrators such as Amazon EKS or Google GKE.
• Exposure to low-latency financial systems, quantitative research tools, or high-performance computing environments.

Compensation & Benefits

• Competitive base salary paired with performance-based incentive opportunities.
