Life at Plume

At Plume, we believe that technology isn't about moving faster, it's about making life’s moments better. Which is why we’ve built the world's first, and only, open and hardware-independent service delivery platform for smart homes, small businesses, enterprises, and beyond. Our SaaS platform uses WiFi, advanced AI, and machine learning to create the future of connected spaces—and human experiences—at massive scale.

We now deliver services to over 60 million locations globally and have managed over 3 billion devices on our platform. We’re expanding rapidly, pioneering a new category, and we achieved our Series F funding in just four years. Our customers include many of the world's largest Internet Service Providers (ISPs) who look to Plume to help them evolve their smart home offerings while gleaning insights from their own data.

With a bias for action and a love for being trailblazers, the team at Plume embodies a combination of relentless curiosity and imaginative innovation. We challenge ourselves to think in ways that other companies don't, work to do what should be done (rather than what can), and if we can’t do it exceptionally well, we don’t do it. It’s how we've assembled a team of world-class builders, thinkers, and doers. And it’s how we’re reinventing what’s possible every day.

Role Description

We're looking for a Senior Manager of Information Security to lead and mature our security program at a critical inflection point. We've already achieved ISO 27001 and SOC 2 Type 1 certifications — the foundation is in place. Now we need a hands-on leader who can turn that foundation into a durable, well-run program: formalizing policies and procedures, building a high-functioning security team, and protecting our infrastructure, networks, cloud environments, and applications — all without slowing down the engineers and developers who build our products.

This is not a "policy for policy's sake" role. You'll be the person who makes security a natural part of how we build software, not an obstacle to it.

Responsibilities

Program & Governance

Own and mature the information security program, ensuring full alignment with ISO 27001 and SOC 2 requirements, including the transition to SOC 2 Type 2.
Author, formalize, and maintain the policies, standards, and procedures required to close any remaining gaps and sustain certification readiness (risk management, access control, incident response, vendor/third-party risk, change management, business continuity, etc.).
Run the internal control environment: risk assessments, control testing, audit evidence collection, and remediation tracking.
Manage relationships with external auditors, pen testers, and compliance partners.

Security Engineering & Operations

Own the security of infrastructure, networks, cloud environments (AWS/GCP), and applications end to end.
Set the strategy and roadmap for identity and access management, network and cloud security architecture, endpoint protection, vulnerability management, logging/monitoring, and incident response.
Establish and continuously improve secure SDLC practices — threat modeling, secure code review, dependency and supply-chain security, CI/CD pipeline security.
Own incident response: build the plan, run tabletop exercises, and lead the response when needed.

Team Leadership

Lead, coach, and develop security team — establishing clear roles, workflows, and a sense of ownership.
Build a team culture rooted in partnership rather than gatekeeping: security as an enabler engineers want to work with, not a blocker they route around.
Define how the team engages with Engineering and Product (embedded reviews, self-service tooling, clear SLAs) to minimize friction and rework.

Cross-Functional Partnership

Act as the primary security voice to Engineering, Product, IT, Legal, and executive leadership.
Translate security risk into business terms for leadership and the board; make pragmatic, risk-based decisions rather than defaulting to "no."
Support sales and customer trust efforts (security questionnaires, customer audits, trust center) as a well-run program becomes a competitive advantage.
