About the Role
As a Senior Account Manager at Colibrix One, you'll take full ownership of our most complex and strategically important merchant relationships. Beyond managing a larger portfolio, you'll act as a go-to expert within the Account Management team: mentoring colleagues, sharing best practices, and helping raise the standard of client service across the team. This is a senior individual contributor role, ideal for an experienced fintech professional who wants to deepen their impact without moving into formal people management.
Key Responsibilities

- Handle escalations and sensitive client situations, driving them to resolution and protecting long-term relationships
- Identify growth opportunities within your portfolio (upsell, cross-sell, volume expansion) and contribute to client retention and revenue targets
- Monitor portfolio performance and client health, proactively flagging risks and proposing action plans
- Mentor and coach Account Managers: support them with difficult cases, share knowledge, and help new team members ramp up
- Contribute to training materials, internal playbooks, and onboarding guides for the team
- Act as the voice of the client internally, feeding insights to Product, Compliance, and Operations to shape improvements and new solutions
- Challenge existing processes and lead initiatives that improve efficiency and client experience
- Ensure the client database and account records for your portfolio are accurate and up to date
Your Profile
- Strong client-first mindset with a track record of building long-term B2B relationships
- Confident communicator, able to negotiate, influence, and hold difficult conversations with senior client stakeholders
- Natural mentor who enjoys helping others grow and sharing expertise
- Strategic and analytical thinker, comfortable working with data to assess portfolio performance
- High level of autonomy: able to manage a complex workload and make sound decisions independently
- Proactive and solution-oriented, with the confidence to challenge established norms
What you need to succeed in this role
- 2+ years' experience in account management or a similar client-facing role within a regulated entity (payments, banking, or fintech)
- Proven experience managing key or strategic accounts, including complex merchant onboarding
- Solid understanding of payments products, merchant risk, and compliance requirements (KYC/KYB, AML)
- Experience mentoring or informally coaching colleagues is a strong advantage
- Higher education in Business Management, Economics, or a related field is an advantage
- Excellent written communication skills and the ability to explain complex topics clearly
- Fluency in English and Russian (additional languages are an asset)
What We Offer
- Opportunity to shape the future of fintech solutions within a growing company
- A collaborative and supportive team environment
