About the Role
At 3E, we believe that long-term customer success is the foundation of sustainable growth—for our clients and for our business. We’re seeking a strategic, relationship-driven Customer Success Manager (CSM) on a 2-year fixed-term contract to support a key book of business within our EMEA region. This role offers an exciting opportunity to make a significant impact, with the potential for future opportunities as our organization continues to grow.
In this role, you’ll act as a trusted advisor and advocate for your customers, helping them unlock the full potential of their investment in 3E solutions. You’ll lead with insight, drive adoption, and shape success plans tailored to real business outcomes. Your efforts won’t just influence renewals and expansions—they’ll directly impact customer satisfaction, retention, and growth.
You’ll work in close collaboration with dedicated Account Managers (AMs), aligning efforts across shared books of business. Together, you’ll identify and prioritize high-value accounts, proactively engage key stakeholders, and navigate risks with clarity and confidence.
Success in this role means delivering measurable customer outcomes and strong Net Revenue Retention (NRR), maintaining a high cadence of proactive, value-led engagements, cultivating trusted relationships across customer and internal teams, and taking ownership in a dynamic environment where strategic thinking and operational excellence go hand in hand.
If you’re energized by meaningful work, thrive in collaborative settings, and are ready to make an impact in a high-growth, mission-driven organization, this is your opportunity to do more.

- Become a subject matter expert in 3E ERC+ and other 3E products and contribute to team knowledge sharing
- Track usage, engagement, and account health metrics to inform actions and demonstrate impact
What Makes You a Great Fit
- 2+ years in Customer Success, Account Management, or client-facing SaaS/tech roles
- Experience managing a book of business and working in tandem with Account Managers
- Proactive mindset with excellent communication and relationship-building skills
- Strong business acumen and data-driven decision-making
- Comfortable operating in ambiguity and fast-changing environments
- Confidence in engaging with global stakeholders
- Fluent in English and Bulgarian, with excellent written and verbal communication in both.
