Site Reliability Engineer (Network)

Overview

As a Site Reliability Engineer with strong networking skills in our Cloud Infrastructure (SRE) team, you help the team own the networks that keep Loft running: cloud networking, VPN and site-to-site connectivity, segmentation, and routing across our offices, test equipment, and ground stations. You keep them reliable, observable, and secure as we scale. You coordinate with IT on the network components that interface with the physical infrastructure used by employees, and with the Test-Infrastructure team to ensure our test equipment is securely accessible.

You’ll work the way an SRE team works: defining reliability in measurable terms (SLOs for connectivity and ground-station availability), instrumenting the systems that prove it, managing the network as code, and automating away toil so on-call load doesn’t grow with the fleet. Beyond the network, you’ll help the SRE team across its broader scope by participating in all the daily work just like a regular SRE: platform reliability and expansion, incident response, planning and user support.

Responsibilities

• Participate in the design and implementation of Loft’s network architecture ; cloud networking, VPN/site-to-site, segmentation, and routing across offices, ground stations, and test equipment
• Tighten the network security posture : segmentation, access, and connectivity hardening
• Manage the network as code : IaC provisioning, CI/CD, and GitOps
• Define SLOs for connectivity and ground-station availability, and own the observability (metrics, logs, tracing) that measures them; Grafana-centric stacks are a plus
• Investigate and resolve reliability issues with root-cause analysis and durable fixes; reduce operational toil through automation
• Contribute to the SRE team’s broader reliability and incident-response work, fostering the SatDevOps culture and Loft’s DNA

Must haves

• 4–5 years in network engineering , with deep hands-on networking: routing, VPN/site-to-site, segmentation, DNS, firewalling
• Hands-on Software-Defined Networking : comfortable managing networks programmatically / as code (everything we run is IaC)
• 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 haves

• 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

Benefits

• 100% company-paid medical, dental, and vision insurance option for employees and dependents
• Flexible Spending (FSA) and Health Savings (HSA) Accounts offered with an employer contribution to the HSA
• 100% employer paid Life, AD&D, Short-Term, and Long-Term Disability insurance
• Flexible Time Off policy for vacation and sick leave, and 12 paid holidays
• 401(k) plan and equity options
