NuxGame is a B2B iGaming technology provider. We deliver turnkey casino and sportsbook platforms, game aggregation, and sweepstakes products to operators worldwide, across four product lines: Turnkey Traditional, Sweepstakes Turnkey, Game Aggregation, and Sweepstakes Game Aggregation.

Our customers are operators. Their back office teams work in our platform every day, and their players use it every time they deposit, verify their identity, or withdraw.

We are looking for a Product Manager to join our Finance Team. You will own everything on the platform that touches money, player identity, and player protection—spanning seven product domains with one dedicated engineering team behind you.

What You Will Do

• Payments and PSP
  • Own the payment roadmap across all four product lines and decide what gets built, what gets configured, and what gets refused.
  • Own the internal payment gateway as a product: integration contract, provider onboarding, error handling and retries, logs, and the tooling support uses to investigate a stuck transaction.
  • Own the technical and product side of PSP relationships and work with our PSP Manager, who owns commercial terms and provider selection.
  • Drive deposit and withdrawal conversion: cashier UX, method visibility and ordering, error minimisation, hosted versus platform side flows, retry and cascading logic.
  • Own crypto and Web3 coverage: networks, confirmations, on ramp providers, wallet based authorisation and deposits.
  • Shorten the time it takes to launch a new provider by standardising the integration, so a new PSP becomes configuration rather than custom development.
• Fraud, KYC and Compliance
  • Own the fraud and risk engine: rules and thresholds, risk scoring, verification flows, duplicate account and bonus abuse detection, manual review load.
  • Own third party KYC and AML integrations end to end, from provider evaluation and platform requirements through rollout to operators.
  • Turn licensing and jurisdictional requirements into configurable platform capability instead of per operator custom work.
  • Hold the balance between fraud prevention and conversion, and defend where you put the threshold.
• Auth and Identity
  • Own registration and login as a conversion product, including social and Web3 registration.
  • Own the relationship between authentication and verification: what a player can do before KYC, what unlocks after it, and how that differs by jurisdiction and by operator.
  • Own back office authentication, permissions, and audit logs as an operator facing product.
• Segmentation
  • Own segmentation as a shared service: how segments are defined, evaluated, and consumed across payments, limits, verification, and reporting.
  • Make it usable by operators without engineering involvement: rule builder, preview and validation before a segment goes live, predictable behaviour when several segments match one player.
  • Own the cost side of it: evaluation performance on large player bases and what happens when a segment changes mid-session.
• Reporting, Limits and Responsible Gambling
  • Own operator facing financial reporting, dashboards, and export tooling.
  • Own the limit framework (deposit, loss, wager, session) and geo blocking as jurisdiction aware, operator configurable capability.
  • Own the responsible gambling toolset and make sure it satisfies the licences our operators hold.

What We Expect From You

• You own the roadmap for your domains and you defend it. Prioritisation is your call to make and to explain, not something you escalate by default.
• You write specifications that an engineer can build from without a business analyst in between: scope and non scope, flows, edge cases, dependencies, acceptance criteria.
• You work with data yourself. You define the metric, pull the number, and check it before you act on it.
• You go deep on the technical side. You read API documentation, review integration contracts, and hold your own in a discussion with engineers.
• You design for many operators at once. Every decision is a decision about configuration, defaults, and backward compatibility, not about a single customer.
• You close the loop after release. A feature that shipped and moved nothing is not a delivered feature.

Requirements

Must Have

• 5+ years in product management, with at least 3 years owning payments, fraud and risk, or financial products in iGaming, fintech, or payments.
• Hands on experience with PSP and payment aggregator integrations: REST APIs, request and response construction, webhooks and callbacks, idempotency, status and error mapping, reconciliation.
• Practical understanding of the trade offs between hosted payment pages, iframe, and fully platform hosted cashier flows, including where PCI scope, conversion, and support load land in each.
• Experience with several payment method families: cards, e-wallets, bank transfer and local rails, vouchers, and crypto (networks, confirmations, on ramp providers).
• Experience integrating KYC and AML providers, and owning or building a rule based fraud or risk engine.
• Experience with rule based configuration and player segmentation: defining segments, resolving conflicts between overlapping rules, and giving business users a safe way to change them without a release.
• Working knowledge of the regulatory requirements affecting deposits, withdrawals, KYC, and responsible gambling in at least two or three jurisdictions.
• Data fluency: deposit success rate, approval rate by provider and method, withdrawal processing time, chargeback rate, verification funnel conversion. You can pull these yourself.
• B2B product experience. Our users are operators and their back office staff, not only end players.
• Structured written communication in English. Russian or Ukrainian for internal team communication.

Nice to Have

• Experience in a multi tenant white label platform serving dozens of operators at once.
• Sweepstakes or social casino experience, where purchase and redemption flows differ from classic deposit and withdrawal.
• Experience with payment orchestration platforms, smart routing, and cascading.
• Experience with Metabase or a comparable BI stack, and enough SQL to validate a number.
• Practical use of AI tooling in the product workflow for discovery, documentation, and analysis.

What We Offer

• Full ownership of a product area that directly moves revenue for dozens of operators, with a dedicated engineering team behind it.
• A direct line to the CPO and to top management. Decisions here take days, not quarters.
• Remote work with a distributed team, or an office in Limassol if you prefer one.
• Competitive salary, flexible hours, and paid time off.

We work with iGaming operators of all sizes to help them expand into new markets or strengthen their existing brands. As a casino software company, we provide solutions that help build outstanding brands and achieve business goals. And now we are looking for a Technical Writer to join our team.

What will be your responsibilities:
• Create and maintain high-quality documentation: how-to guides, release notes.
• Simplify complex information into clear and structured content.
• Work closely with the Technical Writing Team Lead to improve documentation standards and participate in planning and content lifecycle management.
• Collaborate with engineering, DevOps, QA, product, and support teams to gather information and validate documentation accuracy.
• Use generative AI tools to assist with proofreading documentation and checking if all is written in accordance with the standard.
• Deliver documentation in sync with timelines.

What we expect from you:
• 1+ years of proven experience as a Technical Writer or in a related role in software or SaaS environments.
• Excellent written English (С1), conversational (B2);
• Solid knowledge of the Software Development Life Cycle (SDLC), Agile/Scrum methodologies, and iterative product development.
• Practical experience using AI tools (e.g., ChatGPT, Claude, Gemini) for writing assistance, prompt creation, and content acceleration.
• Excellent attention to detail, analytical thinking, proactive mindset, ownership of deliverables, and ability to work independently under deadlines.
• You can share a writing portfolio as part of the hiring process.

It’ll be a plus:
 

• Familiarity with UX writing and the ability to craft microcopy, UI text, and contextual help messages.
• Understanding of the iGaming domain (casino games, sportsbook, slots, regulatory compliance, etc).
• Hands-on experience with documentation tools such as Jira, Git, and Markdown.
• Experience documenting RESTful APIs and working with tools such as Swagger, OpenAPI, or Postman.
• Familiarity with formats like JSON, YAML, XML, and a basic understanding of HTML/CSS.

What we offer:
 

• Working hours: 09:00/10:00 to 17:00/18:00 (Kyiv time) (Mon-Fri);
• Remote work format;
• Timely payment of wages and official employment;
• A friendly team and a pleasant atmosphere without pressure, stress, and other negative things.

We believe in the importance of unlocking the inner potential of each team member, and we have an open and democratic system of work organization.

We are waiting for you on our team!

About Five Jars

Five Jars is a US-based digital product and engineering company with a distributed team across the United States and Europe.

For nearly 10 years, we have designed, built, integrated, and supported complex digital platforms for nonprofit organizations, membership-based organizations, cultural institutions, healthcare organizations, and other mid-market clients.

Our work includes digital products and platforms, custom integrations, portals and self-service experiences, web and mobile applications, managed services, and our own SaaS products, Screen Pulse and Deyra.

We are now evolving our commercial direction, with a stronger focus on digital products, integrations, platforms, automation, managed services, and recurring product revenue.

We are looking for a hands-on commercial leader who can take ownership of this transition from the business development and sales side.

The Role

This is not a traditional sales management position.

Initially, you will be the primary individual contributor responsible for business development, sales, and presales. You will personally generate and qualify opportunities, run discovery calls, prepare proposals, negotiate, follow up, and close deals.

At the same time, you will help rebuild and improve Five Jars’ commercial function, identify what works, refine our positioning and target markets, establish repeatable acquisition channels, and eventually build a small sales and business development team.

The core mission of the role is simple: build a practical and repeatable commercial function that consistently creates qualified opportunities and converts them into revenue.

What you will do

• Own both pipeline creation and sales conversion, from initial outreach or inbound inquiry through contract signature.
• Build and execute a focused lead-generation strategy across outbound, inbound, referrals, partnerships, previous opportunities, existing clients, events, and other relevant channels.
• Define and refine ICPs, buyer personas, target accounts, priority markets, and qualification criteria.
• Run business-focused discovery calls, identify client needs, stakeholders, budgets, timelines, and decision processes, and translate them into clear commercial solutions.
• Prepare proposals, estimates, presentations, follow-ups, and commercial materials, and independently close straightforward opportunities.
• Lead larger and more complex opportunities, involving founders or technical specialists when their input is needed.
• Review Five Jars’ existing sales process, CRM pipeline, proposals, lost opportunities, and lead sources, and identify where opportunities are being lost.
• Improve qualification, discovery, sales stages, CRM discipline, forecasting, follow-up, sales materials, and commercial KPIs.
• Work with company leadership to refine Five Jars’ go-to-market direction, service packaging, positioning, pricing, target industries, and commercial messaging.
• Develop existing client accounts through consultative conversations around integrations, modernization, digital products, automation, AI-enabled functionality, managed services, and other relevant opportunities.
• Support the commercial development of Five Jars’ SaaS products, Screen Pulse and Deyra, including discovery, demos, proposals, closing, and market feedback.
• Develop referral, technology, agency, and industry partnerships.
• Work closely with marketing, delivery, engineering, and company leadership.
• Over time, identify which commercial capabilities should be added, participate in hiring, and build and manage the future commercial team.

What we are looking for

• Strong experience owning the complete B2B sales cycle in custom software development, digital products, systems integration, digital agencies, or related professional services.
• Proven experience personally generating, qualifying, progressing, and closing opportunities.
• Strong track record selling services to clients in the United States.
• Experience closing mid-market technology or professional services deals, not only low-cost SaaS subscriptions.
• Strong discovery, negotiation, objection-handling, and closing skills.
• Experience preparing proposals, statements of work, estimates, presentations, and RFP responses.
• Ability to understand software delivery well enough to communicate credibly with both business and technical stakeholders.
• Experience building or improving sales and business development processes in an environment where the function was not yet fully established.
• Strong CRM discipline and ability to work with pipeline data and forecasting.
• Ability to operate independently without extensive day-to-day involvement from founders.
• A hands-on mindset. You should be comfortable doing the work yourself before building a team around it.
• Strong written and spoken English, C1-C2 level for non-native speakers.
• Based in Europe or the US, with meaningful overlap with US Eastern Time business hours.

Strong plus

• Experience selling both professional services and software products, building business development functions, working with HubSpot, developing partnerships, or selling digital products, integrations, portals, platforms, SaaS, or managed services.
• Experience or existing relationships in nonprofit, membership, healthcare, fitness, cultural, education, or association markets would also be valuable.

This role may be a strong fit if you are someone who

• Is commercially ambitious but realistic, comfortable with ambiguity, proactive, self-directed, and able to make decisions without waiting for detailed instructions.
• You care more about qualified pipeline and revenue than outreach volume or vanity metrics. You are comfortable challenging assumptions, testing new approaches, and building structure without creating unnecessary bureaucracy.
• You should also genuinely enjoy being hands-on. This is not a role where proposals, follow-ups, outreach, or discovery are delegated to an existing sales team from day one.

What you will have

• You will have access to Five Jars’ existing clients, case studies, proposals, HubSpot data, historical opportunities, and previous commercial efforts.
• You will work directly with company leadership and receive technical support from delivery and engineering specialists for complex opportunities. You will also have support from the existing marketing resource for website, content, campaigns, and sales materials.
• You will have significant ownership of the commercial function and the opportunity to influence sales processes, service packaging, positioning, commercial tools, and future go-to-market direction.
• Once a repeatable commercial model is established, you will have the opportunity to build the future sales and business development team.

What we offer

• Full-time remote work.
• Fixed compensation plus performance-based commission with no artificial earning ceiling.
• Significant ownership and autonomy in building the commercial function.
• Direct access to company leadership.
• Opportunity to influence Five Jars’ future commercial direction.
• Paid vacation, sick leave, and public holidays.
• Professional development and support for relevant industry events.
• Flexible working hours with required overlap with US business hours.

Our partner is a leading B2B iGaming supplier delivering engaging casino content to regulated markets worldwide. Since 2012, they’ve been building high-quality gaming experiences through a modern cloud-native platform that powers hundreds of operator brands across multiple jurisdictions.

Their Platform Solutions team sits at the heart of that ecosystem, enabling seamless integrations between the company, operators, aggregators and platform providers.

They’re now growing the team and looking for a Senior Integration Manager who thrives on ownership, enjoys solving technical challenges and wants to operate at the intersection of Product, Engineering and partners.

About the Role

This is not a traditional Integration Manager or Project Manager role.

They’re looking for someone who combines strong technical understanding with excellent stakeholder management and genuine ownership.

You’ll own partner integrations from initial technical discovery through to launch and beyond, becoming the primary technical contact for your portfolio of operators and aggregators. You’ll work closely with Product, Engineering and QA while representing the company externally, ensuring integrations are delivered successfully and issues are resolved efficiently.

The role is highly cross-functional and requires someone who is equally comfortable discussing API behaviour with engineers as they are leading technical conversations with partners.

Main Responsibilities

– Own end-to-end technical integrations with operators, aggregators and platform providers.
– Act as the primary technical contact for assigned partners throughout onboarding, launch and
BAU.
– Drive multiple integrations simultaneously while managing priorities and timelines.
– Troubleshoot complex integration issues, working closely with engineering teams to identify
root causes and drive resolution.
– Review API documentation, validate integration requirements and support partners throughout
implementation.
– Coordinate technical testing, certification and go-live activities.
– Work closely with Product, Engineering and QA to ensure successful delivery.
– Improve integration processes, documentation and partner onboarding experience.
– Build trusted relationships with both technical and non-technical stakeholders.

What Success Looks Like
– Successful people in this role:
– Take ownership rather than simply coordinate.
– Investigate issues independently before escalating.
– Build trust with engineers and external partners.
– Communicate technical concepts clearly.
– Drive integrations through to completion.
– Continuously improve processes rather than simply maintaining them.

Mandatory Requirements

– Strong experience in Integration Management, Technical Account Management, Solutions
– Engineering or a similar technical customer-facing role.
– Previous experience within iGaming or another API-heavy B2B SaaS environment.
– Solid understanding of REST APIs, HTTP, JSON, authentication methods and webhooks.
– Good understanding of API testing and troubleshooting methodologies.
– Experience investigating integration issues using logs and monitoring tools.
– Understanding of networking fundamentals including DNS, SSL/TLS and connectivity
troubleshooting.
– Ability to review technical documentation and API specifications.
– Excellent communication skills and confidence working directly with engineers and external
technical teams.
– Strong ownership mindset with the ability to drive work independently.
– Fluent English.

Nice to Have
– Experience with OAuth, JWT or HMAC authentication.
– Exposure to observability tools such as Kibana, Grafana or Datadog.
– Previous software development experience.
– Experience working with cloud-native platforms.
– Leadership or mentoring experience.
– Experience improving integration frameworks, tooling or documentation.

We offer

– Work on a modern cloud-native platform serving regulated markets worldwide.
– Solve technically interesting integration challenges.
– Own your work from discovery through production.
– Collaborate with experienced engineers and product teams.
– Influence how integrations are delivered and continuously improved.
– Remote-first environment with flexible working.
– Competitive salary and quarterly bonus.
– Unlimited annual leave and sick leave.
– Private medical insurance.
– Learning and development budget.
– Genuine opportunities for career growth into technical leadership.
