Enterprise Customer Success Manager

Are you ready to drive real change in healthcare? At Semble, we’re transforming private healthcare with our SaaS clinical system. Already trusted by thousands of clinicians and used in the care of millions of patients, we’re the UK market leader in private primary care and the fastest-growing practice management software provider. Backed by leading investors, including Mercia Ventures, Octopus Ventures, and Smedvig Ventures, we’re scaling rapidly, and we need an exceptional Enterprise Customer Success Manager to drive impact across some of our most influential customers.

Location

This is a London-based hybrid role. In the Success team, we expect two days per week in our London office, with flexibility for the remainder. Regular client visits are part of the role, and you should be comfortable with travel across the UK.

The role

The private healthcare sector is moving fast. PE-backed clinic groups are expanding across multiple sites, and patient-facing healthtech businesses are scaling their clinical operations at pace. Ambitious operators are growing quickly, often without the internal structures that more established organisations have spent years developing. They choose Semble because they need a platform that can grow with them, and a CS partner who understands that pace.

As an Enterprise CSM at Semble, you will own a focused portfolio of up to 40 accounts spanning upper mid-market to enterprise, with individual ARRs typically ranging from £50 k to £400 k (with some larger Enterprise accounts expected in the future). Some will be large, well-structured healthcare organisations where your work centres on deepening value and unlocking the next stage of growth. Others will be scaling operators where internal processes are still forming, senior stakeholders are changing, and the commercial relationship needs consistent, active management from your side. NRR is your core metric. You will maintain a clear picture of where every account stands against it, working closely across sales, product, support, and marketing to protect and grow revenue. How you manage and coordinate across those internal relationships matters as much as what you deliver directly with your customers.

You’ll report to Emma, our Head of CS and join our CS team with a remit to own and develop how we manage some of our most strategically important accounts.

What you’ll own

• Your portfolio's commercial health: A clear, live view of where every account stands against NRR, what needs attention, and where the growth opportunity sits.
• Your knowledge of your book should be instinctive rather than something you pull together before a review.
• Relationships at every level: From the people using Semble day to day through to the senior leaders who hold the budget.
• Senior access is not assumed here; it is built through the quality of your work and the credibility you earn over time.
• Expansion you found, not expansion you were handed: Proactive identification and progression of commercial opportunities, working in close partnership with sales.
• Customer insight that actually lands: Translating what you hear on the ground into specific, actionable input for product, marketing, and leadership.

What you’ll bring

• Senior CSM experience: A track record of managing high-value accounts (£50 k to £500 k+ ARR), with evidence of conducting QBRs and engaging at exec/C‑suite level.
• A clear upward trajectory in CS: Ideally including promotion within the same organisation, not just a series of lateral moves.
• NRR ownership: A personal track record of positive NRR and exceptional GRR across an owned portfolio, with strong renewal and upsell performance you led rather than just supported.
• Stakeholder progression: You can point to specific accounts where you built your way into senior and executive relationships from operational starting points.
• Commercial instincts: You think in revenue terms and act on them, treating expansion conversations and commercial risk as natural parts of how you manage a portfolio.
• Comfort with a wide product: You’ve worked with software that customers critically depend on to run their business.
• Product curiosity and adoption ownership: You take genuine interest in how a wide, operationally embedded product works in practice across different types of customers.
• Resilience in fast‑moving environments: Experience with fast‑scaling or operationally demanding clients where you’ve created clarity and commercial outcomes.
• AI literacy: You actively use AI tools to increase your own effectiveness and have hands‑on experience building or customising workflows and agents.
• Data and systems fluency: Proficient in Excel, CRM (HubSpot or equivalent), BI tooling and customer health tools.
• Degree educated or equivalent.

Bonus points for

• Experience working in healthtech or with customers in the private UK healthcare market.

Why join Semble?

• Be part of something big: be part of a mission‑driven company transforming healthcare.
• Work with exceptional people: join a smart, ambitious, and supportive team.
• Impact: join an evolving Enterprise CS function with genuine scope to shape how we manage and grow our most strategic accounts.

What you’ll get in return

• The great feeling that comes with knowing you do something that matters.
• Autonomy and ownership – we’ll set the vision and share the context, then we trust you to run with things.
• 36 days off: 25 holidays + bank holidays + 3 extra days (birthday and ‘feel good’ days).
• Private health Insurance – covering physical and mental health, as well as dental and optical!
• Get the tech you need – you will get the latest MacBook and take your pick across a wide range of equipment to set up your home office ergonomically.
• Work alongside an inspiring team – our two founders have started Semble after a successful startup exit.
• Fantastic office space in Central London, right outside Monument – with a roof terrace, weekly animations, loads of natural light, and cute doggies!
• The usual free bits coming with nice offices (barista coffee, tea, fruits, happy hours and activities…).
