NorthwoodSpace Senior Infrastructure Engineer (Platform) owns and operates cloud infrastructure stack supporting global phased array ground stations. Responsible for infrastructure as code, cloud networking, incident response, and security compliance.

Responsibilities

Own and operate all components of the cloud infrastructure stack: cloud accounts, hosted k8s clusters, CA, secrets, IAM, the observability pipeline. Take a defined scope and execute it without ongoing oversight.
Build and maintain infrastructure as code. Define and implement GitOps practices and proper CI gates to test, audit, and approve infrastructure changes.
Implement cloud-side networking: VPCs, transit route tables, VPNs and Direct Connect attachments, egress and ingress inspection. Partner with the network engineering on cloud to site handoff.
Carry on-call for the cloud stack. Resolve the majority of incidents independently and run post-incident reviews for the ones you own.
Partner with security engineering and compliance on controls implementation in your areas: policies, IAM boundaries, logging coverage, evidence collection, CVE mitigation.
Treat toil as a design signal. When manual work repeats, automate it or fix the underlying system.
Write and maintain runbooks, design docs, and component documentation. Keep them current with the system.
Collaborate across infrastructure, platform software, security, and ground station operations on cross-cutting work.
