About the role

Key responsibilities & impact

Build and scale the infrastructure behind the service. Design and operate the systems that carry millions of messages a day — compute, networking, routing, and throughput — at a volume where a fraction of a percent is thousands of clients.
Run storage at scale. Petabytes of customer data across a distributed storage fleet: capacity planning, performance tuning, backups, and data integrity.
Automate everything you touch. Our infrastructure lives in code. If you did it manually twice, the third time should be a pull request.
Engineer how we ship. Build the testing and deployment pipeline that lets a platform this large change safely — infrastructure tests, preflight checks, progressive rollouts. Confident releases are an engineering achievement, not an accident.
Own monitoring and observability. Metrics, logs, SLOs, and alerting — build the systems that surface a problem while it's still small, so it's solved before anyone notices it.
Fight spam and abuse. Tune the filtering engines, rate limits, and authentication that stand between millions of mailboxes and everyone trying to get into them.
Solve problems at the root. When something surfaces, the interesting question isn't how to close the ticket — it's what change makes that entire class of problem stop happening.
Share what you learn. Review code, write the runbook, explain the failure mode. The team gets stronger, or it doesn't scale.

Requirements

What you’ll need

Strong Linux experience (5+ years) — deep and hands-on, not just comfortable at a shell.
On-prem and cloud. We run most of our systems on our own hardware, with parts in the cloud (GCP, AWS, Cloudflare). We're looking for either a strong on-prem and virtualization background (Proxmox, KVM, bare metal) with cloud exposure, or a strong cloud background with real hands-on on-prem experience.
Infrastructure as Code — Ansible, Terraform, or equivalents. You trust automation, and know how to do it right.
Programming or scripting in Go or Python (bonus if both). Occasionally Lua or Rust show up too — we're happy to lean on AI for the long tail.
Production experience with databases, caches, and queues — MySQL, PostgreSQL, Redis/Valkey, Memcached, or similar.
Containers and orchestration — you've experience running workloads on Kubernetes and Docker.
Storage fundamentals — filesystems, distributed storage, replication (Ceph or similar) is a plus.
Networking fundamentals — DNS, TCP/IP, TLS, HTTP, and routing.
