• Work with Risk to identify suspicious, incentivised or low-quality traffic and with Legal & Compliance to enforce brand, advertising and responsible-gambling requirements.
  
  CRM, Promotions and Player Lifecycle
   
• Coordinate segmented campaigns and automated journeys across onboarding, activation, retention, reactivation and loyalty using email, push, SMS and onsite/in-app channels.
• Maintain the casino and sportsbook promotion calendar, coordinating welcome offers, reloads, cashback, free spins, tournaments, major events and reactivation campaigns.
• Ensure offers, eligibility rules, limits, terms and conditions, consent and suppression rules receive all required commercial, Risk and Legal & Compliance approvals before launch.
• Run structured A/B tests across audiences, offers, messages, creatives, channels, timing and landing pages, and apply learnings to future campaigns.
  
  Analytics, Governance and Cross-functional Improvement
   
• Produce concise weekly and monthly reporting covering FTDs, conversion, CPA/CAC, ROAS, NGR contribution, LTV, retention, bonus cost, traffic quality and channel profitability.

About us

UAPP.AI is a product company. We build AI-powered mobile applications used by over 10 million people. The full product cycle stays in-house — from the idea to scale and monetization. Decisions are fast and data-driven, without bureaucracy.
 

The Role

We run a subscription product across mobile and web. Payments go direct, through our own provider stack — Stripe, Unlimit, Payable, Traspay, SolidGate, Checkout.com, ADN, Apple.

We are looking for a Head of Payments to strengthen the payments direction: onboarding new providers and products, domain compliance, fees, reconciliation and approval rate on rebills.

The role is hands-on: you work alongside the team, not only assign tasks.
 

What you will do

• Provider onboarding: new PSPs, plus new products with providers we already work with — applications via agents, merchant ID registration, entities
• Domain compliance: preparing the websites we submit for onboarding to meet provider requirements — knowing what has to be stated, how and where (terms, refund and subscription cancellation policy, pricing, product description, contacts, support) and keeping it current after underwriting
• Recurring and rebills: retry logic, soft/hard declines, payment-method update flows, reducing involuntary churn
• Approval rate: audit by GEO, provider and card scheme, routing and cascading priorities
• Commercial terms: negotiating fees and rolling reserves, auditing commissions to see where the money leaks
• Reconciliation and reporting: settlement reconciliation, payment reporting, cost transparency per product and provider
• Analytics: your own dashboards on payment metrics, built with AI tools
   

What we expect

• 4+ years in payments, at least 2 at Head / Lead level
• A portfolio of several PSPs: Stripe, SolidGate, Checkout.com, Unlimit and similar
• Merchant onboarding: applications, merchant IDs, underwriting
• Understanding of provider compliance requirements for websites: what has to be stated and where
• Recurring payments: rebills, decline handling, churn caused by failed payments
• Approval-rate and fee optimization — with numbers behind it
• Willingness to work hands-on and use AI tools daily
• English B2+
   

Nice to have

• Mobile subscriptions, IAP, web-to-app funnels
• Negotiating enterprise terms with Tier-1 providers
   

What we offer

• Fully remote, full-time
• A working stack and a team already running the direction — you join a live process
• Fast decisions without long approval chains
• A product with 10M+ users and a growing subscription business — the result of your work shows on the revenue chart
• Competitive USD-pegged compensation, reviewed on results

2. Call with the CEO

- Build the interfaces yourself in TypeScript, React, and Next.js
- Contribute to the iOS app using SwiftUI

Our Mission and Vision

At Solidgate, our mission is clear: to empower outstanding entrepreneurs to build exceptional internet companies. We exist to fuel the builders — the ones shaping the digital economy — with the financial infrastructure they deserve. To achieve that, we're on a bold path: to become the #1 payments orchestration platform in the world.

We believe the future of payments is shaped by people who think big, take ownership, and bring curiosity and drive to everything they do. That's exactly the kind of teammates we want on board.

We're building the #1 payment orchestrator in the world — and the names behind us prove it. Clients include Bolt, Ajax, Nova Post, MEGOGO. Trusted by giants like J.P. Morgan. Ranked #2 in the "Employer of the Year 2026" award by Forbes Ukraine.

About the Role and the Team

Our Platform stream acts as a backbone for product teams, handling the complexities of infrastructure, efficient technical solutions, and development frameworks. This allows product teams to concentrate on what they do best: developing and refining product features and experiences.

⚡ This role is for a builder. You'll take ownership of teams inside our Platform stream — the merchant-facing side of the shared services every other product team and merchant at Solidgate runs on.

Your mentor — Mykola Stasiuk, Senior Product Manager on the Platform stream, who leads the other two, data-oriented teams.

What You Will Own

You'll shape and evolve these core components:

• Auth — authentication, authorization, access management across all admin panels
• Notification system — how merchants and internal teams get informed, reliably
• Audit and Approval Manager — logging and approval workflows that hold up under scrutiny
• File Management — file upload, export, and report generation
• Bulk operations and MCP
• UI Kit — the shared component library other teams build their interfaces on

Why This Is Exciting

• Real leverage — one good decision here moves dozens of teams and every merchant at once, not just your own backlog
• Strong technical culture — you'll work with engineers who think about architecture, not ticket counts
• Fast feedback — ship something, and you'll see how it performs within days, not quarters
• Since the domain is technical, you're working shoulder-to-shoulder with engineers constantly — meaning you build technical depth in a fraction of the time other PMs take
• You shape it, not inherit it — parts of this domain are still being formed, so you decide how it works

You'll be great at this if:

• you have 2+ years in a B2B product — what matters isn't your title, but your background: a technical foundation and real cases where you've built new solutions and features, and shaped the direction of the product
• you're comfortable enough with APIs and CI/CD that you don't need an engineer to explain the basics
• you bring curiosity, drive, and strong cognitive skills to everything you do
• you're a structured thinker who brings order to ambiguous, cross-team requests
• you find common ground with strong-opinioned engineers without losing your own point of view

We exist to fuel the builders — the ones shaping the digital economy — with the financial infrastructure they deserve. To achieve that, we’re on a bold path: to become the #1 payments orchestration platform in the world.

We believe the future of payments is shaped by people who think big, take ownership, and bring curiosity and drive to everything they do. That’s exactly the kind of teammates we want on board.

We're building the #1 payment orchestrator in the world — and the names behind us prove it. Clients include Bolt, Ajax, Nova Post, MEGOGO. Trusted by giants like J.P. Morgan. Ranked #2 in the "Employer of the Year 2026" award by Forbes Ukraine.

About the Role
We're looking for a Lead Marketing Designer who will shape how Solidgate looks, feels, and is remembered.

You'll get full ownership of Solidgate's creative function, along with the resources and trust to build, change, and transform it. You'll shape and evolve our visual language: a design code built on typography, color, composition, imagery, and motion that makes Solidgate recognizable at a glance, across every channel and at every scale.

This is a leadership role, not a task queue. You'll set the art direction, create concepts for key marketing campaigns, lead a team of freelance designers, and build a clear process for design requests from marketing, sales, and content. Together, you'll bring the brand to life across events, social, email, sales materials, and the website.

We're making a big bet on marketing, and design is at its heart. No design for decoration. Fast execution and visible impact.

What you'll own
— Building and leading Solidgate's creative and brand function
— Art direction and the quality bar across everything we put out
— The brand: identity, guidelines, website visuals, and brand assets
— Concepts for key marketing campaigns, from idea to launch
— A team of contractors, and growing an in-house design team over time
— A clear process for design requests from marketing, sales, and content

You're a great fit if you have
— 4+ years in design, including experience as a Lead, Art Director, or Creative Lead, ideally in B2B product companies, fintech/SaaS, or B2B marketing agencies
— Experience leading designers or freelancers: setting briefs, giving feedback, and owning the final result
— Strong grasp of typography, composition, layout, and branding fundamentals
— Proficiency in Figma, Photoshop, and Illustrator, plus experience preparing materials for print
— Video editing and motion skills (After Effects, Premiere Pro, or similar) for short social content
— Strong understanding of modern AI tools and workflows, and the ability to build them into the design process
— Ability to manage multiple stakeholders and shifting priorities, and to make decisions without a detailed brief
— English proficiency at B1 level or higher

Nice to have
— Experience with web graphics and animation
— 3D skills (Blender, Cinema 4D)
— Experience creating or refreshing brand guidelines

Why it's exciting:
 Ownership from day one. The creative function is yours to build: vision, team, processes, and results.
 No limits on tools or ideas. Experiment with AI, new formats, and bold solutions. Whatever drives results is welcome.
 Ship fast, see impact. Your work goes straight into campaigns, emails, and sales materials, and you see the results every day.
 Design that moves the business. You work side by side with the teams that bring in clients. You know the goal, you influence the metrics, and nothing is designed just for decoration.
 Range. Social, presentations, events, product content, email. No two weeks look the same.
 Room to scale. We're growing fast and investing heavily in marketing, so your function grows with us.
