Site Reliability Engineer (Network)

The role

You will help own Loft's networks, including cloud networking, VPN and site-to-site connectivity, segmentation, and routing across offices, test equipment, and ground stations. You will also help the SRE team with reliability, incident response, planning, and user support.

What you will do

• Participate in the design and implementation of Loft's network architecture across offices, ground stations, and test equipment
• Tighten the network security posture through segmentation, access, and connectivity hardening
• Manage the network as code using IaC provisioning, CI/CD, and GitOps
• Define SLOs for connectivity and ground-station availability
• Own the observability (metrics, logs, tracing) that measures those SLOs
• Investigate and resolve reliability issues with root-cause analysis and durable fixes
• Reduce operational toil through automation
• Contribute to the SRE team's reliability and incident-response work

Required qualifications

• 4 to 5 years in network engineering
• Deep hands-on networking: routing, VPN/site-to-site, segmentation, DNS, firewalling
• Hands-on software-defined networking, managing networks programmatically as code
• Strong public-cloud networking experience, ideally GCP (VPCs, peering, hybrid connectivity)
• Comfortable operating on a Kubernetes platform (k8s, Docker) and occasionally writing code
• Infrastructure-as-Code (Terraform or similar) and a CI/CD-driven, GitOps workflow
• An SRE mindset: SLOs, observability, and reducing toil through automation
• Ability to debug connectivity issues in a complex, hybrid network environment
• Degree in Computer Science or a related field, or equivalent practical experience

Nice to have

• Network certifications (CCNP or similar)
• Hands-on experience with GitOps frameworks (ArgoCD, FluxCD)
• Interest or experience in FinOps and cost-optimized architectures
• Familiarity with security practices: vulnerability scanning, threat detection, risk mitigation
• Understanding of orchestration in resource-constrained environments, like space systems
• Grafana-centric observability stacks

Benefits

• Equity
• Up to 35 days of paid time off (vacations and RTT) and flexible working hours
• Health and life insurance
• Lunch vouchers
• Cross-office travel opportunities between San Francisco, Colorado, and Toulouse
• Company and team off-sites and events
• Relocation assistance to Toulouse when applicable

Before you apply

• Your resume must be attached in English, as it will be reviewed by people across offices
• Applicants are encouraged to apply even if they do not meet every qualification
