Description

We are looking for a hands-on Technical Product Owner / Business Analyst to join our in-house Platform Team and take ownership of the day-to-day backlog and delivery flow.

This is a hands-on execution role with a strong focus on requirements, documentation, backlog management and delivery quality. You will not be responsible for setting the overall product strategy — your focus is making sure that the agreed priorities are translated into high-quality work and delivered as expected.

Requirements

• Experience as a Product Owner, Business Analyst or similar role working directly with software development teams.
• Strong experience working in an Agile/Scrum environment.
• Excellent requirements-gathering and analytical skills — you can turn a business request into a clear, buildable solution.
• Strong written communication skills and experience creating detailed specifications, user stories and acceptance criteria.
• Good technical understanding and the ability to communicate comfortably with developers, understand system dependencies, limitations and integrations.
• A hands-on approach to validation — you are comfortable checking delivered functionality yourself rather than relying solely on a "Done" status.
• Strong attention to detail and a structured approach to managing information and documentation.
• Excellent communication and stakeholder management skills.
• Experience working with Jira, Confluence or similar tools.
• Experience in iGaming / online casino is required.

Nice to have:

• Experience with VIP, CRM, bonuses, gamification or experimentation platforms.
• Experience working with multiple stakeholder groups competing for the same development capacity.
• Experience working with in-house platforms or internal product teams.

Responsibilities:

• Own and maintain the platform backlog — keep it structured, prioritised and continuously ready for development.
• Work closely with Product Managers and domain owners across VIP, Payments, Casino, Sportsbook, CRM and other product areas to understand their needs.
• Challenge vague or incomplete requests, ask the right questions and identify the actual business requirement behind the initial ask.
• Break larger initiatives into clear, manageable and deliverable features.
• Write detailed user stories, functional requirements and acceptance criteria that developers can work from without ambiguity.
• Maintain accurate and up-to-date product and feature documentation in Confluence or equivalent tools.
• Lead backlog refinement sessions with the development team and ensure everyone has a shared understanding of the requirements.
• Stay involved during development, answer questions, clarify requirements and quickly resolve ambiguity or blockers.
• Review and validate delivered features against acceptance criteria before they are considered done.
• Work closely with QA where deeper testing or additional scenarios are required.
• Identify dependencies, risks, scope changes and gaps early and communicate them to the Platform Lead.
• Keep stakeholders informed about progress, status and potential issues related to their requests.

What success looks like:

In your first 3 months, you will have full ownership of the day-to-day platform backlog. The development team will consistently have clear, refined and buildable work ahead of them, while stakeholders will receive clear answers on their requests and status.

The Platform Lead will be able to rely on you to manage the backlog and execution flow independently, identify issues early and ensure that what reaches production is aligned with what was actually requested.

Benefits

• Freedom to choose where to work: work from anywhere in the world with the freedom of remote options.
• Flexibility: enjoy flexible working hours that let you balance your personal and professional life while staying focused on delivering great results.
• Corporate English speaking club: improve your English proficiency with regular practice and expert guidance.
• A Culture That Cares: thrive in a friendly environment where a strong corporate culture builds connections, drives innovation, and makes you feel truly valued.
• Comfort Fuels Success: experience comfortable conditions that inspire productivity and foster professional growth, giving you the tools and space to excel.
• Accelerate Your Growth: seize career advancement opportunities in a rapidly expanding marketing company. As the company scales, so will your professional journey.

The role involves day-to-day legal support of the business, contract work, regulatory matters, and cooperation with compliance, finance, payments, marketing, and management teams.

Responsibilities
