Job summary

Commure is seeking a Senior Software Engineer to own the networking backbone of a multi-cloud, AI-driven healthcare platform. You will design, implement, and operate end-to-end network infrastructure used across product teams to enable scalable, secure, and reliable services.

In this role you will tackle multi-cloud foundations, hybrid connectivity, Kubernetes networking, edge services, and zero-trust security, delivering network-as-code with GitOps practices and modern observability tooling.

Qualifications

• 6+ years of experience in cloud native networking or infrastructure engineering.
• Deep proficiency in TCP/UDP/ICMP, BGP, IPsec, NAT, firewalls and segmentation.
• Experience with public cloud networking (GCP, AWS, Azure).
• Kubernetes and cloud-native networking (CNI, eBPF, Gateway API, Envoy, Istio).
