Security Product Engineering Manager

ActiveCampaign is the autonomous marketing platform that empowers teams to automate their campaigns with AI agents. They are seeking an Engineering Manager to lead their Security Product Engineering team, responsible for authentication and authorization services, while driving operational excellence and collaborating with various teams to enhance security architecture.

Responsibilities:

• Lead and develop a team of senior and staff-level engineers — provide hands-on technical mentorship, clear prioritization, and career development that keeps strong ICs engaged
• Spearhead the migration and standardization of identity services onto a centralized platform, partnering with Platform Engineering on the long-term architecture
• Drive operational excellence by hardening the existing identity stack, reducing incident frequency, and building the observability and rigor necessary to run mission-critical infrastructure
• Participate in architectural and code reviews — you should be able to evaluate an identity flow, review a platform configuration, or debug a token validation issue alongside your engineers
• Partner with engineering teams across the organization to improve their integration experience with identity services — better documentation, clearer APIs, faster onboarding
• Collaborate with security and compliance teams to ensure identity architecture supports regulatory requirements and fraud prevention initiatives
• Shape the security culture by moving the team toward broader platform security concerns, establishing secure development patterns that allow other engineering teams to build with confidence
• Represent the team in incident reviews and cross-functional planning, translating high-level security trade-offs for non-technical audiences without losing the underlying substance

Requirements:

• 5+ years of hands-on software engineering experience with significant depth in identity, authentication, or authorization systems—you have built and operated these systems at scale
• 3+ years of engineering management experience leading engineers (not just tech-leading projects) — you know how to run effective 1:1s, give hard feedback, and create clarity in ambiguous environments
• Hands-on, current technical skills — you can read and review code, evaluate architecture decisions, and credibly challenge or support your team's technical direction
• Proven success in system consolidation, ideally having led the migration from legacy or bespoke auth implementations to standardized, centralized platforms
• Strong understanding of modern identity protocols and standards (authentication, authorization, federation, token-based architectures)
• Strategic vision to see beyond identity, with a background in infrastructure hardening and secure development lifecycles (SDLC)
• Strong communication skills — you can translate identity and security concepts for product managers, platform engineers, and executives without losing the technical substance
• Experience working in a SaaS environment with multi-tenant identity concerns and the security implications that come with them
• Familiarity with fraud-adjacent identity concerns: account takeover prevention, credential stuffing mitigation, adaptive authentication
• Background in platform or application security beyond identity — secure development lifecycle, infrastructure hardening
• You've built or significantly improved developer-facing documentation, SDKs, or integration guides for identity services
• Experience operating in a security organization that functions as an engineering team, not a compliance checkpoint
