Principal Product Manager

Mimecast protects over 42,000 organisations from sophisticated cyber threats. They are seeking a Principal Product Manager to join their Human Risk Management team, responsible for owning strategic product areas and leading initiatives to manage human-driven security risks. The role involves defining and driving the product roadmap, leading cross-functional programs, and mentoring other product managers.

Responsibilities:

• Own the end-to-end roadmap for a subset of HRCC capabilities, including the Human Risk Insights Report and related analytics and reporting features
• Define clear problem statements, success metrics, and prioritization rationale grounded in customer feedback, usage data, and business goals
• Partner with engineering to scope, sequence, and deliver features — driving quality outcomes on time and with clear tradeoffs articulated
• Translate complex customer needs into product requirements, UX direction, and acceptance criteria
• Lead strategic product initiatives from concept through launch, including PR/FAQ-style business cases for new capabilities
• Build and maintain a structured process for tracking at-risk HRCC accounts, partnering with CS and Support to intervene early and prevent churn
• Serve as the PM point of contact for a set of customer escalations related to HRCC product issues — triaging, prioritizing, and communicating resolution plans
• Identify systemic patterns in customer escalations and translate them into product investments that reduce recurring friction
• Partner with Integrations PM to ensure third-party integrations are well-positioned for customer enablement and adoption, and contribute to integration adoption programs in collaboration with customer success and solutions engineering teams
• Drive cross-functional accountability across engineering, CS, support, MSOC, and go-to-market teams — keeping complex, multi-stakeholder programs moving without direct authority
• Maintain clear documentation, status tracking, and stakeholder communication for programs you own
• Own go-to-market readiness for features you ship — including positioning, internal enablement, and adoption planning in partnership with product marketing and sales engineering
• Provide mentorship and guidance to other PMs on the team, helping elevate product thinking and execution standards across the HRM group

Requirements:

• 8+ years of product management experience, with 3+ years in B2B SaaS or enterprise software
• Proven track record owning features or product areas end-to-end — from discovery and requirements through delivery, launch, and adoption
• Strong analytical instincts — you use data to define problems, measure outcomes, and prioritize ruthlessly
• Experience driving cross-functional programs involving engineering, CS, and go-to-market teams
• Experience managing customer-facing product conversations and executive-level escalations, with the ability to balance customer needs against roadmap constraints
• Familiarity with risk management concepts. Direct cybersecurity experience is a plus
• Ability to work closely with engineering on technical decisions — you don't need to write code, but you can hold your own in architecture and data model discussions
• Comfort working with product analytics tools (Pendo, Amplitude, or equivalent) to track adoption and inform prioritization
• Proficient in leveraging generative AI tooling (Claude, ChatGPT, Cursor) to accelerate analysis, documentation, and prototyping workflows
• Strong communicator — written and verbal — with the ability to distill complex problems into clear narratives for engineering, leadership, and customers
• Detail-oriented with strong operational instincts — you can run a structured program, maintain accountability across teams, and keep things moving without being told
• Comfortable operating in ambiguity — you can structure problems, validate hypotheses, and move quickly with incomplete information
• Experience mentoring other PMs or leading through influence without direct authority
