product owner for email security

CloudLinux makes Imunify360, a suite of security products that protects millions of websites across the web hosting industry. Its email security line provides inbound anti-spam filtering integrated with hosting control panels and an outbound SMTP gateway that protects sender reputation and keeps legitimate mail out of spam folders.

• Turn the product backlog into a sequenced engineering plan with estimates, dependencies, and a release train

• Own model-release quality gates, including measured spam catch rates, false-positive deltas, and rollback paths
• Keep technical debt visible and funded by incorporating it into the roadmap
• Report delivery status and risks to engineering leadership weekly, with an owner and due date for every item
• Own the email stack architecture with the architecture group; review designs, write and approve ADRs, and make build-versus-buy decisions with explicit trade-offs
• Review critical-path code and designs for mail flow, rate limiting, quarantine, and authentication; set standards for tests, observability, and safe rollouts
• Own production health, including SLOs, alerting, capacity, and sending-infrastructure deliverability
• Command product-impacting incidents, coordinate remediation across teams, inform partners, and author post-mortems within 24 hours with named owners and dates
• Lead a distributed team through 1:1s, goal setting, performance reviews, and career development
• Hire, define candidate profiles, conduct technical interviews, onboard, and mentor engineers
• Establish working agreements for asynchronous work, including written decisions, public-by-default communication, and durable artifacts
• Model and coach effective use of coding agents, including prompting, code review, tool-boundary awareness, context provision, iteration, error recovery, and end-to-end task completion
