💬 In short:

🔸 The project is on the right track, but still young enough for you to become its co-author.

🔸 Here you will get freedom, income and a share in a business that grows every day.

We're not a big agency, and we don't want to be. We're a team of under 20 people, we've been doing this for nearly 12 years, and we care more about doing good work than growing fast.

Right now, we need a PM who gets that — and can bring structure without killing the energy.

You'll own projects end-to-end across clients in biotech, fintech, telecom, recycling, and beyond — from early discovery through to live operations. Day-to-day, you'll work closely with designers, less so with developers, and occasionally coordinate with marketing. You'll report to the PM department lead and work directly with the CEO.

You're not expected to be an AI expert — but we do expect you to think about where it fits. Whether that's streamlining how briefs get written, how feedback gets processed, or how documentation stays current — we want someone who sees AI as a working tool, not a buzzword.

What you'll be doing:

• Defining project objectives, timelines, resource plans, and success criteria
• Translating business requirements into clear, actionable briefs for the team
• Running discovery, sanity checks, and ongoing project analysis
• Presenting solutions and progress updates to clients
• Collecting and synthesizing feedback between clients and internal teams
• Maintaining accurate, up-to-date project documentation
• Decomposing scope, managing priorities, and owning delivery accountability
• Auditing existing processes and establishing better ones where needed

Must-haves:

• 3+ years of PM experience in a digital agency or product environment
• Fluent English — written and spoken (you'll be client-facing)
• Strong analytical thinking and structured communication
• Experience managing full product lifecycles — from concept to launch
• Comfort with tools like ClickUp, Airtable, Float, Notion, or equivalents
• Ability to lead without authority — mentorship mindset, not just task management
• Practical curiosity about AI — you actively look for ways to use it in your workflow, not just follow the hype
• Genuine curiosity and a drive to keep learning

Nice to have:

• Background or exposure to digital marketing
• Experience working with startups or early-stage products

What you'll get:

• Full remote
• Flexible working hours
• 30 days of paid time off per year (including sick leave)

Hiring process:

• Qualification call with our recruiter
• Team interview with the PM lead and CEO
• English proficiency conversation

About the Mission

We are building an AI-driven payments ecosystem designed to transform a $50B industry still dominated by slow, legacy processors. As Head of ISO, your mission is to architect, lead, and scale our merchant acquisition engine. You will set the commercial direction, build high-performing processes, and drive measurable revenue impact - first through hands-on execution, and then by leading automated, scalable systems you help define.

What You’ll Do

• Architect and launch the ISO function end-to-end: strategy, operating model, tooling, and execution;
• Own the full merchant pipeline: prospecting → qualification → underwriting coordination → negotiation → closing → onboarding/activation;
• Define and refine commercial fundamentals: pricing strategy, merchant segmentation, and offer frameworks aligned with risk and margins;
• Build scalable operational workflows and enforce portfolio health ratios (chargebacks, fraud, dispute rates), in close coordination with Risk/Compliance and Processing partners;
• Map and manage banking/acquiring coverage (“bank mapping”) and route merchants to the right partners based on vertical, geography, and risk profile;
• Build and maintain relationships with PSPs, acquirers, and key commercial partners to unlock approvals, improve conversion, and expand capacity;
• Standardize playbooks, scripts, and governance, ensuring every opportunity is tracked, advanced, and optimized for conversion;
• Drive process automation with Product & Engineering: convert manual tasks into AI-powered workflows across outreach, qualification, CRM hygiene, and reporting;

• Deliver advanced reporting, forecasting, and KPIs to leadership; act as a senior commercial partner shaping revenue strategy and growth targets.

You’re a Strong Fit If

• You’ve built or scaled an ISO/merchant services function and know what “from zero to repeatable engine” looks like;
• You have strong domain understanding of underwriting, processing economics, risk, and portfolio management;
• You are equally comfortable leading and executing - entrepreneurial, hands-on, and operationally rigorous;
• You thrive in fast-changing environments, build structure quickly, and drive predictable outcomes at scale;
• You operate with urgency, handle high-stakes initiatives, and take full ownership of results.

Required Skills

• Extensive experience in ISO / merchant services / payment processing, ideally with proven ISO build/launch exposure;
• Track record of closing complex merchant deals and managing merchant portfolios with strong risk awareness;
• Ability to define pricing/segmentation and align commercial execution with underwriting and partner constraints;
• Strong operational discipline: scalable workflows, CRM governance, forecasting, and KPI-driven management;
• Excellent communication, negotiation, and relationship management; leadership maturity and resilience.

Nice-to-Have

• Experience in fintech, SaaS, or payment technology environments;
• Familiarity with CRM systems, outbound engines, or automation workflows;
• Background in building or managing distributed commercial teams.

Why This Role Matters

• Shape the commercial backbone of a fast-moving, high-impact payments ecosystem.
• Direct access to founders and leadership, with zero bureaucracy and high decision velocity.
• Full ownership and autonomy: you build the system, the team, and the results from scratch.
• Competitive compensation with significant performance-based upside.
• A rare opportunity to lead innovation in one of the most lucrative and underserved segments of fintech.

We’re building financial infrastructure designed to outperform legacy processors by an order of magnitude.

This is a role for someone who wants their work to change how financial infrastructure is built.


What You’ll Do

• Ship features in days — not months — with iterative, high-velocity execution
• Design backend systems supporting hundreds of merchants with zero bottlenecks
• Own the Laravel-powered backend stack end-to-end
• Drive engineering decisions and lead by impact, not hierarchy
• Help shape a no-fluff, high-performance engineering culture

• You thrive in ambiguity and move with urgency
• You ship fast, learn faster, and solve problems without waiting for permission
• You know when to optimize and when to deliver quickly
