THE OPPORTUNITY

• We are an early-stage AI-powered SaaS company hiring our first dedicated Senior DevOps / Site Reliability Engineer to own production infrastructure, reliability, security, PostgreSQL operations, monitoring, recovery, and deployments.
• This is a senior hands-on role working directly with the Founder/CTO. It is ideal for an experienced DevOps, SRE, Platform, Cloud Infrastructure, or Production Engineer who enjoys taking ownership of real production systems and building reliable infrastructure from the ground up.
• Our environment includes Supabase, PostgreSQL, serverless/edge functions, scheduled database jobs, Vercel, and modern web infrastructure.

WHAT YOU WILL OWN

• Own production reliability across development, staging, and production.
• Manage deployments, configuration, environment variables, secrets, and CI/CD workflows.
• Operate and troubleshoot PostgreSQL in production, including performance, indexing, backups, restores, and disaster recovery.
• Monitor scheduled jobs and detect failures, delays, or unexpected behavior.
• Strengthen authentication, access controls, secrets management, database security, and multi-tenant data isolation.
• Review and improve Row-Level Security policies.
• Implement vulnerability monitoring, dependency patching, and remediation processes.
• Build dashboards and alerts for application errors, database performance, deployments, authentication, scheduled jobs, and infrastructure health.
• Lead production troubleshooting, incident response, root-cause analysis, rollback procedures, and operational runbooks.
• Recommend infrastructure, reliability, security, and scaling improvements as the platform grows.

WHAT WE NEED

• 5+ years of experience in DevOps, Site Reliability Engineering, Platform Engineering, Cloud Infrastructure, Production Engineering, DevSecOps, or a closely related field.
• Strong hands-on experience with PostgreSQL in production.
• Experience with database backups, restores, performance tuning, indexing, and troubleshooting.
• Experience supporting serverless, edge-function, or modern cloud architectures.
• Strong experience with CI/CD, deployments, environment management, and production troubleshooting.
• Solid knowledge of access control, secrets management, authentication, vulnerability management, and secure cloud operations.
• Experience implementing monitoring, logging, alerting, and observability.
• Demonstrated ownership of real production incidents.
• Ability to troubleshoot independently across infrastructure, database, application, and integration layers.
• Strong professional English and communication skills.
• Ability to operate successfully in a fast-moving startup with significant individual ownership.

STRONG PLUS

• Hands-on experience with Supabase, Vercel, Deno, Node.js, pg_cron, Row-Level Security, multi-tenant SaaS, Sentry, Datadog, or Grafana.
• Direct Supabase experience is strongly preferred, but candidates with deep PostgreSQL and comparable serverless production experience are encouraged to apply.

WHAT SUCCESS LOOKS LIKE

• You will establish reliable production visibility, tested database recovery, strong security controls, effective incident response, practical operational documentation, and an infrastructure foundation capable of safely supporting continued product and customer growth.
