Senior Network Reliability Engineer

Group 1001 is a consumer‑centric, technology‑driven family of insurance companies on a mission to deliver outstanding value and operational performance by combining financial strength and stability with deep insurance expertise and a can‑do culture.

The Platform Engineering Services team at Group 1001 is building a Site Reliability Engineering practice with a network scope. We’re hiring an Sr. Network Reliability Engineer who embodies Innovation and Excellence, and will apply SRE principles — code‑as‑source‑of‑truth, SLOs and error budgets, alerting on symptoms rather than causes, failure‑mode‑first design, and the elimination of toil — to the firm’s network platform from carrier edge through cloud fabric to Kubernetes pod boundary.

This is not a “keep the lights on” role. You will systematically engineer the lights‑on work out of existence, build the abstractions that let other engineering teams express network intent in code, and treat the network as a single engineered system rather than a collection of vendor consoles.

You will operate inside a Dev Sec Ops  practice spanning multi‑cloud, multi‑region environments, and you will partner closely with Cloud and Data Platforms, the NOC/SOC, and Cyber Security to extend reliability practice across the firm.

• Define SLOs and error budgets for the network platform — DNS resolution, edge availability, mesh ingress success, cross‑region path health — and use them to gate changes, not just to color dashboards.
• Lead postmortems with a focus on permanent remediation, not pattern‑recognition.
• Alert on symptoms users feel, not on causes that may or may not produce impact.
• Move network state into code using Terraform (or Pulumi), Ansible, and Python to replace CLI‑driven configuration with declarative, version‑controlled, peer‑reviewed change running through Infra CI/CD.
• Build network policy as intent, not rule lists; express permitted flows, isolated segments, inspected egress, and DNS zone sharing; engineer compilers that translate intent into per‑vendor configuration.
• Use Policy as Code (OPA/Rego, Sentinel, Cilium Network Policy) to catch invariant violations at plan time, not apply time.
• Design, deploy, and manage network infrastructure using Terraform or Ansible, moving the firm away from manual configuration to a code‑first approach.
• Engineer the cloud network platform: operate and extend our multi‑account AWS Landing Zone, build platform abstractions for new accounts or services with declarative inputs.
• Extend platform thinking into the container tier, covering Kubernetes networking, service mesh (Istio, Linkerd, Consul Connect), eBPF‑based observability and policy (Cilium, Hubble), and integration points where mesh‑level authz meets cloud‑tier identity.
• Improve telemetry and observability with intent; build alerts as structured payloads with runbook links, suspected blast radius, and dependency‑aware suppression.
• Author system‑health dashboards for operators and end‑user monitoring dashboards that reflect actual user experience; use Grafana, Elastic, Open Telemetry where each fits.
• Mentor and grow the team, provide technical guidance to junior engineers, foster a culture of learning, and work out loud across Platform Engineering so the patterns you build cross‑pollinate to adjacent domains.
• Handle hardware when required; provide maintenance and configuration support for routers, switches, and firewalls at data centers and offices; bring code‑first practices to physical hardware where possible.
• Serve as an escalation point for network issues, perform troubleshooting with a focus on root cause analysis and permanent remediation, author runbooks and SOPs for the NOC.

• Deep understanding of TCP/IP, BGP, OSPF, VPNs, and SD‑WAN architecture.
• Proven experience with Terraform (state management, modules) and Ansible (playbooks, roles) or similar in a production environment.
• Proficiency in Python for automation and API interaction.
• Hands‑on experience with Cloudflare, Zscaler, and/or enterprise firewalls.
• Experience configuring monitoring tools (Datadog, Prometheus, Grafana) to create meaningful alerts and…
