Description
You're the engineer who maintains 50+ SaaS products while others are still guessing. We need DevOps professionals capable of navigating unknown AWS environments, stabilizing disorder, and driving uptime beyond 99.9% through genuine monitoring, genuine automation, and genuine root-cause analysis. You'll break down complex projects into single-day tasks, deliver production-quality Python or JavaScript, and leverage AI as your assistant.
Most organizations talk about "cloud" while manually nursing individual servers. We're systematizing reliability across dozens of acquired products where original developers have departed and documentation is incomplete. That's the challenge: you'll leverage agents and contemporary tooling to analyze unfamiliar systems 5–10× faster, document your findings, and automate solutions so the same failure never recurs. Rather than judging you on certifications and vendor badges, we'll observe how you troubleshoot in real time, produce a legitimate 5-Whys that identifies a single preventable root cause, and create automations that withstand production conditions.
This is not an L2 "execute the procedure" position. In this role, you author the procedures, architect the deployment from development through staged to 10% to 100% with soak periods and rollback triggers, and construct the monitors that detect corner cases. You block unsafe modifications before anyone executes them. You distinguish infrastructure failures you control from application bugs Engineering controls, and you route permanent solutions to the appropriate team.
You'll operate at the engineering center of reliability, managing infrastructure projects, incident response and root-cause analyses, and change requests with copy-paste-executable runbooks. If you've already operated a significant SaaS product and want to extend that expertise to an entire fleet, come forward. Bring expert-level AWS knowledge, production-quality coding skills, strict scope discipline, and daily, essential use of AI tools. If you're prepared to maintain operational continuity, please apply.
What you will be doing
- Advanced infrastructure migrations, consolidations, production-quality automations, monitoring modifications
- Diagnosing production outages, deploying immediate remediations, and authoring root cause analyses with permanent solutions assigned to the accountable teams
- Authoring, reviewing, and executing production changes, including assessing whether a proposed modification is safe to implement
What you will NOT be doing
- Spending time in Jira and constant status meetings - we value individuals who can deliver solutions, not merely monitor issues
- Supporting legacy systems forever - you'll be authorized to pursue substantial improvements
- Waiting on bureaucratic approval processes - you'll possess the authority to implement immediate remediations to resolve incidents
Key responsibilities
- Lead reliability and standardization of cloud infrastructure across our expanding product portfolio by deploying robust monitoring, automation, and AWS best practices.
Candidate requirements
- Deep AWS infrastructure expertise (this is our primary platform - other cloud experience alone won't cut it)
- Experience owning large production infrastructure and troubleshooting production outages independently (not just following a runbook)
- Experience scripting with Python and Bash for day-to-day administration operations
- Experience managing and migrating production databases with multiple engines (including MySql, Postgres, Oracle, MS-SQL)
- Experience with infrastructure automation (Terraform, Ansible, or CloudFormation)
- Linux systems administration expertise
