Senior Infrastructure Engineer - Remote

Overview

We are looking for an infrastructure engineer who can own our entire cloud stack. You'll build and operate the systems that power billions of requests, improve observability across everything we run, and expand our infrastructure as we grow.

In Short

• Own and improve observability across the entire stack: metrics, logging, alerting, dashboards.
• Architect and operate browser cloud infrastructure: containerized browsers, session isolation, crash recovery, autoscaling.
• Handle websocket connections, CDP tunnels, and TCP-level tuning for browser automation.
• Write and maintain Terraform for all infrastructure. Everything is code.
• Tune autoscaling, capacity planning, and cost optimization.
• Expand to new regions as we grow.
• Debug production issues: memory leaks, zombie processes, network failures.
• Build disaster recovery and incident response runbooks.
• Work with Linux systems, Dockerfiles, container orchestration daily.
• Mentor other engineers on infrastructure best practices.

Requirements

• Deep production experience with AWS: ECS, EKS, Fargate, RDS, VPC, IAM.
• Fluent in Terraform. Everything is infrastructure as code.
• Comfortable with Linux systems, Docker, container orchestration.
• Experience running headless browsers or similar workloads at scale (Playwright, Puppeteer, raw CDP).
• Understand networking: TCP, websockets, load balancing, multi-region.
• Built observability stacks that engineers actually use (Prometheus, Grafana, Datadog, or similar).
• Fluent in English, written and spoken.
• BSc or higher in CS or equivalent technical field.

Benefits

• Fully Remote. Work from anywhere.
• Equity share. Own a piece of what you're building.
• Profit sharing. When we win, you win.
• Learn fast. Touch every part of a growing SaaS. Ship real products to real customers.
• Annual team retreats (last one in Spain).
