Job description

As Customer Success Manager, you will own the end-to-end customer lifecycle for a portfolio of Fortune 500 accounts — from set-up and onboarding through adoption and value realisation. You will partner with Account Managers on renewals and commercials, with a mandate to deliver customer outcomes, value, and margin.

Key Responsibilities & KPIs:

1️⃣ Value & Success Ownership

  • Co-define success plans: business outcomes, metrics, and exit criteria for pilots.

  • Lead value realisation: publish ROI reports, run bi-annual Value Review cadence with executives.

  • Partner with AMs to secure renewals and expansions.

2️⃣ Product-Led CS:

  • Design scalable onboarding flows, templates, and enablement assets.

  • Run one-to-many onboarding and training programs.

  • Say no to bespoke unless it scales into repeatable patterns.

3️⃣ Automation & Margin:

  • Track and manage COGS per account; drive account-level margin improvement plans.

  • Automate onboarding, reporting, and handoffs across CS/Support/Eng.

  • Instrument time tracking and efficiency metrics for the CS function.

4️⃣ Customer Engagement & Change Management

  • Manage executive comms during incidents/outages; own post-mortems with Engineering; define SLAs with AM/Support.

  • Multi-thread across stakeholders, train champions, and create certification paths.

  • Run user councils, office hours, and adoption programs.

🎯 KPIs will be responsible for 🎯

  • Monthly Active Users (MAUs)

  • Penetration of MAUs

  • Efficiency metric (profitability per account)

  • NPS (in collab with Account Management)


Preferred experience

  • At least 4/5 years experience in B2B enterprise Customer Success (or less if you’ve built CS from scratch).

  • Experience managing Fortune 500 accounts through complex onboarding and adoption cycles.

  • Strong program management skills: able to orchestrate multiple workstreams with exec visibility.

  • Proficiency with product analytics, automation, and data tools.

  • Executive communication skills: confident with VP/C-suite.

  • AI-literate: able to use/compose prompts and leverage no-code tools to automate CS workflows.

  • A product-led mindset: you look for scale, automation, and repeatability before customization.
