[Hiring] Principal Product Manager @Mimecast

Role Description

Mimecast protects over 42,000 organisations from sophisticated cyber threats. We're looking for a Principal Product Manager to join our Human Risk Management team — owning strategic product areas within the Human Risk Command Center (HRCC) platform and leading initiatives that shape how organizations manage and reduce human-driven security risk.

This is a high-impact, senior IC role for someone who can operate from strategy to execution. You'll define and drive the roadmap for multiple HRCC capabilities, lead cross-functional programs spanning engineering, customer success, and integrations, and serve as a subject matter expert on your areas of ownership for internal and external stakeholders. You'll also mentor other PMs as we build out the HRM product team.

Responsibilities

• Product Ownership & Roadmap
  • 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.
• Customer Retention & Product Quality
  • 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.
• Cross-Functional Execution
  • 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.

Qualifications

• 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.

Requirements

• 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.

Benefits

• Competitive salary and benefits package.
• Collaborative, distributed team environment where ownership and initiative are valued.
• Remote (US-based preferred). Occasional travel required for team offsites and customer meetings.
• The base salary range for this position is $172,000 - $258,000 base + benefits.
• This position may also be eligible for incentive plans and other related benefits.
