We are currently looking for a Head of Commercial (Merchant Sales & Portfolio Growth) to join Flintn, a business building and scaling an all-in-one payment platform for online businesses.

  • a strong team;
  • well-established processes.

Next comes a strong growth focus: product development, testing, and integrations aimed at building a global payment platform.

 

What you’ll be focusing on:

  • To build and later lead our commercial function.
  • New merchant acquisition across the European, North American and LatAm markets.
  • Lead generation: outbound, partnerships, ISV and platform channels, events.
  • The Account Management function — retention, expansion, processed-volume growth, and the authorisation-rate value we deliver to merchants.
  • Commercial process: ICP, playbooks, pricing discipline, CRM hygiene.
  • Forecasting of sales and growth in turnover.
  • Hiring and coaching as the function grows.
  • Platform growth commitments and targets fulfilments.

 

You are our ideal candidate if you:

  • Fintech understanding, auth-rate and routing narrative, writing playbooks.

  • Subscription metrics (MRR, involuntary churn, dunning), SaaS-merchant understanding.
  • Retention, expansion, QBRs, portfolio metrics, TPV growth.
  • Merchant sales or general B2B sales understanding.
  • Owned a portfolio number, not just personal bookings; can explain how they moved it.
  • Self-sourced and closed complex merchant deals; holds a price floor.
  • Treats risk as commercial design; knows what they would decline.
  • Hired, coached, and corrected a mis-hire.

 

Our hiring flow:

  • Step 1: Pre-screen.
  • Step 2: Interview with the CEO.
  • Step 3: Test Task.
  • Step 4: Bar-Raising.
  • Step 5: Reference Check.
  • Step 6: Job Offer!

 

What you can expect from working with us:

  • A chance to work on an early-stage payment product. You’ll have the opportunity to make architectural decisions, work with AI and high-level engineering, enjoy technical freedom, and directly influence the product’s development vector. The startup drive — backed by the stability and support of a holding company.
  • From idea to action — minimal steps. Any proposal can turn into real changes in the product or processes. If you have an idea, it will be heard.
  • Your office is wherever it’s convenient for you: home, our Kyiv office, coworking spaces in Lviv or Warsaw, or anywhere else with a stable Wi-Fi connection.
  • Flexible working hours. Plan your day for maximum efficiency: start between 8:00 and 11:00 and finish between 17:00 and 20:00, considering team collaboration hours.
  • Continuous growth is a must. Courses, conferences, and an internal library — we invest in your development because the team’s speed and performance directly depend on the expertise of its people.
  • Health care and wellbeing: medical insurance, a Mental Health program, and compensation for sessions with a psychologist.
    Time to recharge: 28 paid days off per year, sick leave, and all public holidays fully covered.
  • Gifts for special occasions. We celebrate important moments together — we give gifts to mark key milestones in your life and career.
  • Social Impact. The Ukrainian Victory Support program and other charitable initiatives supporting Ukraine.
    An active corporate life: quarterly team buildings, workshops, and other holding-level events.

Our business ambition is to become one of the top 10 payment providers for small and medium-sized businesses. Are you in?
