Job description

Описание

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.

Задачи
  • Turn the product backlog into a sequenced engineering plan with estimates, dependencies, and a release train
  • Run weekly planning, release readiness, and status reporting using measurable data
  • 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
  • Extend agent-assisted development to model and rule pipelines
  • Take ownership of the release train and weekly status within the first 30 days; trace inbound and outbound messages through the stack; complete 1:1s with every team member and document team strengths and gaps
  • Take ownership of on-call and incident command within the first 60 days; publish current SLOs and the top three reliability risks with mitigations; deliver at least one non-trivial change
  • Present an agreed technical roadmap for the email stack within the first 90 days, including a debt-paydown item and staffing recommendation
Требования
  • 5+ Years as a software engineer and 2+ years leading a team of engineers in a product company
  • Strong Linux proficiency at software-engineer user level
  • Ability to read and review production code in a modern high-level language such as Python or Go, and debug live systems
  • Track record of shipping and operating a distributed backend service under real production load, carrying a pager, and running incidents
  • Experience quickly mastering complex technical domains and making credible architectural decisions
  • Practical fluency with observability and data tools, such as Grafana, Kibana/Elasticsearch, or Redash, to assess quality directly
  • Demonstrated people leadership, including 1:1s, performance conversations, hiring, and growing engineers
  • Experience with agentic or AI-assisted development workflows
  • Understanding of ML-driven systems, including model-quality evaluation, training, and production operations
  • Professional proficiency in written and spoken English Availability to work EU hours
  • Будет плюсом: working knowledge of email infrastructure, including SMTP, SPF/DKIM/DMARC, rDNS, IP reputation and warm-up, RBLs, and feedback loops; experience with open-source mail stacks such as Rspamd, SpamAssassin, Postfix, Exim, or Halon, or the web hosting ecosystem and control panels; exposure to ML model lifecycle, training-data quality, evaluation metrics, and detection-system tuning trade-offs; experience running incident and escalation management with external partners
