About Aalyria

Aalyria is a leading technology company that supplies laser communications technology and temporospatial software‑defined networking platforms to the aerospace industry. With technology acquired from Google, Aalyria is at the forefront of innovation in satellite and airborne mesh networks, as well as cislunar and deep‑space communications. We are revolutionizing the orchestration and management of planetary mesh networks using any radio or optical spectrum, any orbit, and any hardware across land, sea, air, and space.

This isn't a "keep the lights on" SRE role. This is a strategic, high‑impact opportunity to build the nervous system for a platform that transforms how networks of satellites, ground stations, and fleets are interconnected and orchestrated. You will be building the core observability stack that ensures the reliability of systems critical to the operation of satellite mega constellations and missions to deep space.

This is a greenfield/brownfield opportunity. You will be a trusted expert, helping to define and implement the strategy and building the tools that empower our engineers. You will support the roadmap to mature our observability stack, moving from cloud‑native tools to a robust, scalable, and insightful platform built on best‑in‑class technologies (Prometheus, Open Telemetry, etc.). If you are an SRE who thrives on platform‑building challenges and wants to be relied upon to build a production‑grade observability stack from the ground up, this role is for you.

Note: this role includes on‑call responsibilities.

• Help design and build Aalyria's centralized observability platform, integrating and scaling tools for metrics (e.g. Prometheus), logging (e.g. Loki), and distributed tracing (e.g. Tempo/Open Telemetry).
• Define, implement, and manage a robust framework of Service Level Objectives (SLOs), Service Level Indicators (SLIs), and error budgets for our core products, ensuring we are launch‑ready.
• Partner with SWEs to implement observability best practices, develop standard templates and documentation, and configure tooling (e.g., Open Telemetry libraries).
• Automate the deployment, scaling, and management of the entire observability stack using Infrastructure as Code (e.g. Terraform) and Git Ops principles (e.g. ArgoCD).
• Partner closely with the core infrastructure team to ensure deep visibility into our Kubernetes clusters and underlying GCP and AWS environments.
• Develop and lead the company's monitoring, alerting, and incident response strategy, driving a culture of proactive reliability and blameless post‑mortems.

• 4+ years of experience in an SRE or platform engineering role, with a focus on observability for large‑scale, distributed compute or network systems.
• Deep, hands‑on expertise building, scaling, and managing observability platforms (e.g., Prometheus, Grafana, Loki/ELK, Open Telemetry, Tempo/Jaeger, Honeycomb, etc.). You have proven experience using these tools to support performance analysis and debugging of complex distributed systems.
• Strong production‑level experience with Google Cloud Platform (GCP) and Kubernetes.
• Experience using Infrastructure as Code (IaC) and Git Ops principles (e.g., ArgoCD).
• Proficiency in a systems programming language, with a strong preference for Go and Python for debugging and writing tooling.
• Demonstrable experience defining, implementing, and managing SLOs, SLIs, and error budgets for production services for high availability distributed systems.

• Experience operating a multi‑cloud environment, specifically GCP and AWS.
• Hands‑on experience with Git Lab CI for CI/CD pipelines.
• Working knowledge of service mesh technologies such as Istio or…
