Job description

Senior Customer Success Manager

Curvestone exists to transform how high-stakes, regulated industries work. Finance, insurance, and law firms shouldn’t be slowed down by outdated, manual processes — they deserve modern, intelligent systems that let them move faster and serve clients better. That’s why we’re building at the forefront of applied AI: automation that is secure, regulator-ready, and proven to handle the critical workflows others can’t.

Our mission is to become the platform of choice for automating the workflows that run regulated businesses. By turning clunky, manual reviews into smart, scalable processes, we help firms unlock efficiency, resilience, and confidence in how they operate.

This is a real-world application of the way in which AI can transform the way professional services work.

Opportunity

We are hiring a Senior Customer Success Manager to own strategic enterprise accounts and help shape the future of Customer Success at Curvestone.

You will work closely with our Head of Customer Success to deliver measurable ROI for clients and ensure that Curvestone AI becomes deeply embedded in their critical workflows. This is a hands‑on, high‑impact role where you will both manage senior client relationships and contribute to building the playbooks, processes, and scalable programmes that will underpin our growth.

Why should you choose Curvestone for the next stage in your career?

• Work with a transformational AI product that’s reshaping how regulated industries operate.
• Tackle a huge market in finance, insurance, and law — with demand for change accelerating fast.
• Backed by recent funding and early customer wins, we’re now building out our go‑to‑market function — the perfect moment to join and make your mark.
• Step in as the first CSM hire and play a defining role in how the function scales up
• Be part of a tight, ambitious team culture where you’ll learn fast, make an impact, and celebrate wins.
• We offer a competitive package, including base salary, commission, and equity.

What You’ll Do

• Lead customer onboarding, ensuring smooth implementation and fast time‑to‑value
• Partner with clients to understand their use cases and processes, map success outcomes, and embed Curvestone AI into their operations
• Own and grow a portfolio of enterprise accounts (six‑figure ACVs), ensuring adoption, retention, and expansion
• Build trusted relationships with senior stakeholders (e.g. Heads of Compliance, General Counsel, CIOs)
• Run regular success reviews, QBRs, and executive check‑ins
• Collaborate cross‑functionally with Solution Engineering, Product, and GTM teams to deliver a seamless customer journey
• Collaborate with Sales on renewals and upsells, ensuring commercial outcomes
• Design and implement CS processes, playbooks, and scalable enablement resources
• Capture and prioritise customer feedback for Product and Engineering
• Act as a senior member of the CS team, supporting and mentoring junior colleagues

About you

• 4+ years of proven Customer Success experience in Enterprise SaaS (B2B), ideally managing six‑figure ACV accounts
• Proven track record of driving renewals and leading upsell/expansion opportunities, not just supporting them
• Experience managing a portfolio of enterprise accounts, with measurable success in adoption, retention, and growth
• Strong client‑facing skills, with the ability to build trusted relationships at senior levels (e.g. Heads of Compliance, General Counsel, CIOs)
• Comfortable navigating technical workflows and product integrations at a high level
• Analytical mindset, able to work with customer health metrics, usage dashboards, and CRM tools to track and improve outcomes
• Comfortable working in a fast‑paced startup environment, thriving with autonomy and ambiguity

Desirable

• Experience in regulated industries (legal, compliance, finance, insurance)
• Experience with or strong interest in AI / GenAI products or data‑driven platforms
• Familiarity with usage‑based SaaS pricing models
• Experience mentoring junior CS team members
• Background as an early CS hire or helping to build out a CS function

What Success Looks Like (First 90 Days)

• Build strong relationships with your initial portfolio of enterprise customers
• Lead successful onboarding for at least one new account, ensuring fast time‑to‑value
• Deliver a QBR and success review that clearly demonstrates ROI and drives expansion opportunities
• Partner with the Head of CS to refine and document the first set of Curvestone CS playbooks
• Provide actionable client insights that directly influence the product roadmap

Our client ICP:

Curvestone serves regulated, document‑heavy industries where compliance is business‑critical. Typical clients are in financial services (mortgage networks, lenders, wealth managers), insurance, and law firms.

We engage with mid‑to‑large‑sized firms that need to scale compliance and oversight without scaling headcount. The buyers we target include:

• Compliance & Risk Leaders – seeking consistency, audit readiness, and Consumer Duty assurance.
• COOs / Operations Leaders – focused on efficiency, cost savings, and process automation.
• Technology / Transformation Leaders – looking for extendable platforms that integrate with existing systems.

Interview process:

Step 1: Intro Call – A short screening conversation focused on background, motivation, and overall fit

Step 2: Hiring Manager interview – A more detailed discussion on skills, mindset, and alignment with the CSM role at Curvestone.

Step 3: Technical interview with Head of Customer Success

Step 4: Final Conversation – A closing stage with a senior leader or team member, ensuring alignment on values, expectations, and mutual fit
