Technical Customer Success Manager

About Us:

We’re looking for a Customer Success Manager (Technical) to join our growing CS team at Proton. You’ll own a book of our most important and high-potential customers and serve as a true partner and trusted advisor—guiding them from onboarding through expansion.

You will be responsible for strategic customer relationships: managing renewals, building executive trust, identifying growth opportunities, and helping customers achieve measurable business value. At the same time, you'll be expected to develop enough technical fluency with our product—especially around data, workflows, and reporting—to confidently guide early troubleshooting steps, assess feasibility, and collaborate effectively with technical teams when needed.

This is not a handoff role—you’ll be expected to take full ownership of your accounts, lead cross-functional collaboration, and escalate when necessary.

We’re hiring someone in the Greater Boston area open to a hybrid schedule (3 days in-office/week). Travel expected: ~10+ times/year to visit customers.

The role:

We are looking for an Enterprise Customer Success Manager to work with our customers who have adopted Proton’s AI-powered CRM. We’re looking for a driven, curious, and strategic Enterprise Customer Success Manager to join our growing CS team at Proton. In this role, you’ll own a book of some of our most important and high-potential customers, serving as a true partner and trusted advisor from onboarding through expansion.

As the valued member of the CSM team, you’ll help customers unlock measurable business value by combining deep product knowledge, strategic thinking, a passion for solving real-world problems, and a willingness to learn the technical basics needed to collaborate effectively with internal teams to move quickly toward solutions. This role is ideal for someone who thrives in complexity, takes ownership end-to-end, and is excited to make a meaningful impact across customer relationships, internal teams, and our company’s growth.

We’re looking to hire someone in the greater Boston area who is open to a hybrid schedule (3 days a week in office). Travel expected: ~10+ times per year to visit customers.

What you’ll do: 

• Own strategic relationships: Become deeply embedded within your accounts—building trust from frontline users to C-suite executives. You’ll lead executive conversations, ensure alignment on goals, and be the primary point of contact across the lifecycle.
  
  
• Drive and demonstrate value: Understand each customer’s business model and strategic priorities. Clearly articulate how Proton’s CRM and Sales AI solutions create impact, and tailor value delivery accordingly.
• Develop and execute account plans: Build success strategies for each customer, aligning adoption and growth goals with measurable outcomes. Track progress, adjust when needed, and drive toward retention and expansion.
• Drive adoption and workflow integration: Ensure customers fully leverage Proton's capabilities by embedding best practices into their day-to-day sales processes. Help customers connect our product to their internal workflows.
• Identify and pursue expansion: Proactively uncover opportunities for upsell or cross-sell (<$50K) and collaborate with Sales to expand Proton’s footprint within your accounts.
• Triage technical needs independently: Learn how our platform works—especially around data, workflows, and reporting—so you can troubleshoot, answer early-stage technical questions, and determine feasibility before looping in Solutions or Support.
• Leverage Looker for insights and storytelling: Use Looker to explore data, identify trends, and surface insights that support your recommendations and value narrative with customers.
• Solve creatively, escalate thoughtfully: When blockers arise, you’ll roll up your sleeves to dig in—whether that means reading docs or understanding what the expected behavior should look like, you’ll own the outcome while collaborating cross-functionally.
• Be the voice of the customer: Advocate internally for your accounts—ensuring their goals, blockers, and feedback are heard by Product, Engineering, and Leadership.
• Contribute to our CS evolution: Bring ideas to improve our playbooks, tools, and ways of working. We’re still building—and your input matters.

You'll be a great fit for this role if you are:

• Strategic and customer-focused—you care deeply about understanding a customer’s business, aligning solutions, and making value visible.
• Confident and comfortable with product mechanics—you don’t need to be an engineer, but you’re happy learning technical workflows, asking smart questions, and troubleshooting in Looker before escalating.
• Curious and proactive—you seek context, follow threads, and don’t wait to be told what’s broken. You action customer needs and support with follow up in a timely manner, ensuring nothing falls through the cracks.
• Accountable—you own your book, your results, and your process. You follow through and follow up until outcomes are achieved.
• Collaborative—you work well with Sales, Product, Marketing, and Support and contribute to a positive, team-oriented CS culture.
• A strong communicator—clear, structured, and confident, from Slack to the C-suite.
•  

Required experience:

• 5+ years experience in a Customer Success role, preferably in an enterprise software environment
• Proven success managing complex, multi-stakeholder relationships—including executive alignment, adoption planning, and expansion
• Ability to think strategically while managing day-to-day account activities
• Excellent communication and relationship building skills—you can adapt your message from frontline users to C-suite executive
• Experience at an early-stage startup strongly preferred
• Experience in using tools like Mixpanel and Looker or enjoy using data to guide decisions and conversations
•
