CloudLinux is the maker of Imunify360 — a suite of security products protecting millions of websites across the web hosting industry. Our email security line covers both sides of the email problem for hosting providers an inbound anti-spam engine integrated with hosting control panels and an outbound SMTP gateway that protects sender reputation and keeps legitimate mail out of the spam folder. We are looking for an Engineering Team Lead to run the team that builds and operates this product line. You will lead a small senior fully remote squad (currently 7–8 people Go and Python engineers a deliverability engineer an anti-spam engineer and data analysis/annotation) and be accountable for what the team ships how reliably it runs and how the people on it grow. This is a hands-on lead role not a pure people-management role. Expect roughly 60% leadership (delivery technical direction coaching incident command) and 40% hands-on engineering (design reviews code review spikes production debugging). You are not expected to be the top individual contributor on the team — you are expected to be able to read every part of the system and hold a credible technical opinion about it. You don t need to arrive as an email expert. If you have led engineers in an adjacent technical domain — infrastructure networking security messaging anti-abuse — and have a track record of getting deep into complex technical territory fast we will teach you the email side. The system you would inherit Inbound filtering an Rspamd-based engine with a trained rule/ML model released on a regular retraining cycle and measured on spam catch rate and false-positive rate. Outbound gateway a Halon-based SMTP relay with per-domain warm-up ladders rate limiting quarantine feedback-loop (ARF) processing and a customer portal — Go services on bare metal. Panel integrations cPanel/WHM Plesk DirectAdmin plus Debian/Postfix deployments for large hosting partners. Data plane Elasticsearch Redis Grafana dashboards and alerting corpus and annotation pipelines feeding model training. Delivery GitLab Jenkins Jira weekly release cadence blameless post-mortems within 24 hours. What you will own Delivery Turn the product backlog into a credible sequenced engineering plan — estimates dependencies and a release train the team actually hits. Run the team s weekly cadence planning release readiness status reporting with real numbers rather than adjectives. Own engineering quality gates for model releases no detection model ships without a measured catch rate and false-positive deltas against the previous model and a rollback path. Keep technical debt visible and funded — negotiate it into the roadmap rather than absorbing it silently. Report delivery status and risk to engineering leadership weekly every item carries an owner and a due date. Technical direction Own the architecture of the email stack together with the architecture group review designs write and approve ADRs and make build-vs-buy calls with explicit trade-offs. Review code and designs on the critical path — mail flow rate limiting quarantine authentication — and set the bar for tests observability and safe rollout. Own production health SLOs alerting capacity and the deliverability posture of our sending infrastructure (IP reputation SPF/DKIM/DMARC rDNS RBL listings). Act as incident commander for product-impacting events coordinate remediation across teams keep partners informed and author the post-mortem within 24 hours with named owners and dates. People Lead a distributed team across the globe 11s goal setting performance reviews and career development. Hire define the profile run technical interviews onboard and mentor engineers Set the working agreements that make async work — written decisions public-by-default communication durable artifacts over meetings. AI-augmented engineering We evaluate engineers here partly on how effectively they work with coding agents. As the lead you are expected to model and coach this prompt specificity review quality on agent-generated code tool-boundary awareness context provision iteration effectiveness error recovery and end-to-end task completion. The team has already scaffolded its repositories for agent-assisted development extending that to the model and rule pipelines is live work. Working with the Product Owner The Product Owner sets priorities owns partner commitments and the roadmap narrative. You own the plan to deliver them and the technical risk in doing so. Escalate scope-versus-capacity conflicts early and in writing with at least two mitigation options. First 90 days 30 days Own the release train and the weekly status be able to trace an inbound message and an outbound message end to end through the stack complete 11s with every team member and produce a written read on the team s strengths and gaps. 60 days Own on-call and incident command for the product line publish the current SLOs and the top three reliability risks with mitigations land at least one non-trivial change yourself. 90 days Present a technical roadmap for the email stack agreed with the PO and the architecture group including a debt-paydown line item and a staffing recommendation. Requirements Must have 5+ years as a software engineer with 2+ years leading a team of engineers (team lead tech lead with people responsibility or engineering manager) in a product company. Strong hands-on Linux background comfortable reading and reviewing production code in Go and/or Python and debugging live systems on the box. Track record of shipping and operating a distributed backend service under real production load — you have carried a pager and run incidents. Experience mastering a complex technical domain quickly and making credible architectural decisions in it. Practical fluency with observability and data tooling to judge quality yourself not via reports (Grafana Kibana/Elasticsearch Redash or equivalents). Demonstrated people leadership 11s performance conversations hiring and growing engineers. Experience working in an agentic / AI-assisted development workflow or a clear appetite to lead one. Professional proficiency in English written and spoken. Availability to work EU hours. Nice to have Working knowledge of email infrastructure SMTP SPF/DKIM/DMARC rDNS IP reputation and warm-up RBLs feedback loops. Experience with open-source mail stacks — Rspamd SpamAssassin Postfix Exim Halon — or the web hosting ecosystem (cPanel/WHM and other control panels). Exposure to the ML model lifecycle training data quality evaluation metrics and the trade-offs in tuning detection systems. Experience running incident and escalation management with external partners.
