Project Manager - SaaS Product Launch Coordination

We are launching a new B2B SaaS product in Q4 and need a freelance PM to own the launch coordination across engineering, design, marketing, and sales. Responsibilities include maintaining and enforcing the project timeline in Linear, running weekly cross-functional syncs, managing dependencies between 6 squads, writing weekly exec status reports, coordinating beta customer onboarding, creating launch day runbook, and managing post-launch bug triage prioritization. PMP or equivalent certification preferred. Must have shipped a SaaS product in a PM capacity — share your most relevant launch in your proposal.
