Engineering Team Lead - Email Security (Imunify Email & Email Gateway)

Stack

Responsibilities

• ▹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
• ▹Own engineering quality gates for model releases: measured catch rate and false-positive deltas, plus a rollback path
• ▹Keep technical debt visible and funded in the roadmap
• ▹Report delivery status and risk to engineering leadership weekly
• ▹Own the architecture of the email stack with the architecture group: review designs, approve ADRs, make build-vs-buy calls
• ▹Review code and designs on the critical path — mail flow, rate limiting, quarantine, authentication
• ▹Own production health: SLOs, alerting, capacity, and deliverability posture (IP reputation, SPF/DKIM/DMARC, rDNS, RBL listings)
• ▹Act as incident commander for product-impacting events

Requirements

• ▹Experience leading engineers in an adjacent technical domain (e.g., infrastructure, networking, security, messaging, anti-abuse)
• ▹Track record of getting deep into complex technical territory quickly
• ▹Comfortable with a hands-on lead role: roughly 60% leadership, 40% hands-on engineering (design reviews, code review, spikes, production debugging)
• ▹Ability to read every part of the system and hold a credible technical opinion, without needing to be the team's top individual contributor
