🌳 Senior Enterprise Client/Customer Success Manager

AI SaaS | Enterprise Platforms | Fully Remote (UK )

Full-time | £90k–£110k + bonus + equity

Areti Group is exclusively partnering with one of the most exciting emerging AI SaaS businesses currently scaling globally.

This is a company entering a major growth phase, with plans to significantly expand over the next two years as demand for its platform accelerates internationally.

This is not a traditional SaaS environment buried beneath layers of process and hierarchy.

This is a lean, product-first AI business building genuinely category-defining enterprise technology — and they are now hiring multiple Senior Enterprise Customer Success Managers to help scale strategic customer delivery, onboarding, adoption, and long-term customer success globally.

While this is not a traditional HR tech or benefits platform, experience working within benefits, pensions, reward, HR tech, global mobility, or enterprise SaaS environments would be highly valuable due to the complexity of the customer landscape and implementation environment.

If you thrive in high-performance environments, enjoy solving complex customer problems, and want real ownership inside a fast-scaling AI company — this is the opportunity.

🌳 Why This Role Stands Out

Most Customer Success roles are reactive.

This one is deeply strategic.

You’ll own the most critical stage of the enterprise customer lifecycle — transforming signed customers into highly successful, fully embedded platform partners.

You’ll operate at the intersection of:

• Enterprise onboarding
• Customer success
• Strategic delivery
• Adoption & enablement
• Operational transformation

You’ll work directly with:

• Global enterprise customers
• Product & Engineering
• Operations
• Leadership
• Customer Experience teams

This is a highly visible role with genuine influence across the business.

No unnecessary layers.

No bloated process.

Just smart people solving hard problems together.

🌳 What You’ll Own

🌳 Enterprise Customer Success & Delivery

You’ll lead enterprise customers from onboarding through to successful adoption and operational rollout.

This includes:

• Running strategic onboarding and launch programmes
• Managing enterprise stakeholder relationships
• Defining onboarding plans, milestones, and success metrics
• Coordinating implementation and configuration activity
• Driving adoption and operational change management
• Supporting successful go-live delivery
• Acting as a trusted strategic partner to enterprise clients

You’ll become the operational lead and customer success owner during the most important phase of the customer journey.

🌳 Strategic Customer Partnership

You’ll partner closely with enterprise clients to help them:

• Embed the platform into operational workflows
• Drive internal adoption
• Realise measurable business value
• Navigate organisational complexity
• Scale usage successfully across teams and regions

You’ll work consultatively with sophisticated enterprise stakeholders in complex operational environments.

🌳 Cross-Functional Collaboration

You’ll operate at the centre of the delivery engine, partnering closely with:

• Sales during customer handover
• Product & Engineering on platform configuration and customer requirements
• Operations teams ahead of launch
• Leadership on delivery priorities and customer outcomes
• Internal teams improving onboarding and customer experience processes

This is a fast-moving environment where ownership and initiative are expected from day one.

🌳 Training, Enablement & Adoption

You’ll help customers maximise platform value by:

• Delivering engaging virtual training sessions
• Supporting change management and rollout initiatives
• Creating onboarding and enablement resources
• Helping customers adopt new workflows successfully
• Driving early-stage customer engagement and platform usage

This role combines strategic delivery with strong client-facing communication and operational leadership.

🌳 Delivery & Customer Success Excellence

This business is obsessed with execution quality and customer outcomes.

You’ll help improve:

• Time-to-value
• Enterprise onboarding experience
• Product adoption
• Customer engagement
• Delivery scalability
• Customer satisfaction

You’ll proactively identify risks, solve problems early, and keep enterprise programmes moving at pace.

🌳 What We’re Looking For

We’re looking for people who combine:

• Customer obsession
• Ownership mentality
• Enterprise stakeholder management

You should have:

• Experience managing enterprise or international customers
• Strong stakeholder management and communication skills
• Experience running multiple complex customer programmes simultaneously
• Experience delivering virtual onboarding or training sessions
• Experience working within fast-moving SaaS or technology businesses

Experience within:

• Benefits

...would be highly advantageous.
