Site Reliability Engineer (Network)

Toulouse, Occitanie4-5 years

Wanna join the adventure?

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. You coordinate 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.

About this role:

Participate in the design and implement 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 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 that power 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 rather than appliance-by-appliance (everything we run is IaC)

Strong public-cloud networking experience, ideally GCP (VPCs, peering, hybrid connectivity)

Comfortable operating on a Kuburnetes 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

Some of Our Awesome Benefits:

Equity, we want you to have an active role in our success

Up to 35 days of Paid Time Off (vacations & RTT ) and flexible working hours, we want you to be at your best

Health and life insurance, we care about your health

Lunch Vouchers, because let’s be honest, we love food! (we even have a slack channel about it #loft-gourmand)

Cross-office travel opportunities between San Francisco, Colorado, and Toulouse to learn from our differences

Company and team off-sites and many other events to work & celebrate together

Relocation assistance to Toulouse when applicable

*Research shows that while men apply to jobs where they meet an average of 60% of the criteria, women and other underrepresented people tend to only apply when they meet 100% of the qualifications. At Loft, we value respectful debate and people who aren’t afraid to challenge assumptions. We strongly encourage you to apply, even if you don’t check all the boxes.

Who We Are

Loft: Space Made Simple.

Founded in 2017, Loft provides governments, companies, and research institutions with a fast, reliable, and simple way to deploy missions in orbit.

We integrate, launch, and operate spacecraft, offering end-to-end missions as a service across Earth observation, IoT connectivity, on-orbit AI, national security missions, and more. Leveraging our existing space infrastructure and an extensive inventory of satellite buses, Loft is reducing years-long integration and launch timelines to months. With more than 30 missions flown, Loft’s flight heritage and proven technologies enable customers to focus on their mission objectives.

With a growing fleet on track to reach 30 satellites by 2027, we are scaling up quickly across our offices in San Francisco, CA | Golden, CO | and Toulouse, France to meet accelerating demand for space infrastructure.

As an international company your resume will be reviewed by people across our offices so please attach a copy in English.
