• Automate critical user journeys, regression scenarios, and high-risk product areas.
• Analyze failed automated tests, identify root causes, and improve test reliability.
• Integrate automated tests into the development and release processes.
• Expand automation coverage during non-release weeks.

Manual Testing
 

• Perform functional, regression, integration, exploratory, and usability testing.
• Test web applications across different browsers and screen sizes.

• Participate in planning, refinement, and release discussions.
• Identify quality risks early and communicate them clearly to the team.
• Contribute to test planning and define appropriate testing coverage for new features.
• Improve QA documentation, processes, and testing standards.

Would be a plus:
 

• Interest in mobile automation (Appium) - there will be an opportunity to explore this area in the future.
• Interest in sports, fitness, baseball, coaching, or performance-tracking products.

Work conditions:
 

• 4 weeks of paid vacation per year.
• Flexible working hours.
• Medical insurance for your peace of mind.
• Professional development support - Launch Labs covers courses, training, and skill growth.
• Individual and group English classes.

We're looking for a CRM Channels & Integrations Manager who will take full ownership of our direct communication channels: SMS, WhatsApp, Telegram, Push Notifications, and IVR.

This is a highly operational and technical role sitting at the intersection of vendor management, API integrations, and CRM operations.

You'll be responsible for the entire lifecycle of communication providers: sourcing vendors, negotiating commercial terms, integrating them into Smartico, monitoring channel health, optimizing costs, and ensuring maximum delivery performance.

Our primary market is India, where communication channels require continuous attention due to changing provider quality, pricing fluctuations, OTP traffic, and strict regulatory requirements. This is not a "set it and forget it" role—you'll own these channels end-to-end.

• OTP traffic monitoring and fraud prevention;
• controlling sending limits and caps;
• monitoring provider balances;
• invoice reconciliation;
• communication channel budgeting;
• optimizing communication costs.

Incident Management

• Respond quickly to incidents such as:
  • delivery failures;
  • blocked sender IDs;
  • provider outages;
  • OTP attacks and SMS pumping.
• Escalate critical incidents to the CRM Lead.
• Prepare post-mortem reports and preventive action plans.
• Keep Product, CRM and CVM teams informed about major channel issues.

Cross-functional Collaboration

• Consult Product and CRM teams on communication channels and webhook configuration.
• Support IVR routing and communication flows.
• Prepare regular reports on channel performance, costs and improvements.

What We're Looking For

• Proven experience working with SMS aggregators, WhatsApp Business Providers (BSP), or similar communication providers at scale.
• Experience managing multiple vendors and negotiating pricing.
• Hands-on experience with:
  • REST API
  • Postman
  • Webhooks
  • API documentation.
• Ability to independently integrate providers without relying on developers.
• Understanding of communication channel economics:
  • message pricing
  • delivery quality
  • conversion
  • ROI.
• Experience monitoring large-scale communication channels.

Nice to Have

• Experience in iGaming, Betting, or Online Gambling.
• Experience working with Smartico or similar CRM/CDP platforms.

Playson is looking for a People Business Partner with knowledge of the Ukrainian language who can operate close to the business, work directly with leaders on organisational challenges, and help maintain a high-performance environment without turning the company into a bureaucratic HR machine.

This role is not about running HR processes for the sake of process.

We are looking for someone who can:

• help leaders make strong people decisions;
• maintain high talent quality;
• Identify organisational risks early.
• and ensure leadership, hiring, and performance problems do not silently accumulate over time.

The PBP works primarily through leaders - not around them.

What you’ll bring

• Knowledge of the Ukrainian language is a must
• 5+ years of experience in HRBP, Head of People, HRD, organisational partnership, or similar leadership-facing roles.
• Strong experience working with leaders in fast-moving environments.
• Ability to challenge stakeholders directly, constructively, and without unnecessary politics.
• Strong judgment and ability to operate in ambiguous situations.
• High level of ownership, maturity, and communication clarity.
• Ability to connect people and topics with business reality and execution impact.
• Comfortable with difficult conversations, organisational tension, and imperfect environments.
• Ability to remain calm, structured, and pragmatic under pressure.
• Ability to build trust with strong personalities and leadership teams while still being able to challenge them when needed.
• Ability to simplify complexity instead of adding bureaucracy.
• Strong business and organisational awareness.

• Interest in scalable organisational practices, operational clarity, and AI-supported People infrastructure.

   

What you’ll do

• Partner with leaders on hiring, team structure, organisational effectiveness, performance, ownership gaps, and delivery risks.
• Push discussions toward decisions and outcomes instead of endless alignment loops.
• Help leaders define what “strong” actually means for critical roles and challenge weak hiring compromises.
• Support leaders in addressing underperformance early and directly.
• Identify early organisational signals such as leadership gaps, burnout, unhealthy dependencies, misalignment, or execution risks.
• Help improve feedback quality, leadership practices, and decision consistency across teams.
• Support practical and scalable organisational approaches instead of overcomplicated HR frameworks.
• Contribute to improving internal documentation, operational clarity, and AI-supported People knowledge infrastructure over time.

This role is not:

• an employee support hotline;
• a process coordinator;
• a “culture activities” owner;
• a passive mediator avoiding uncomfortable conversations;
• or someone hiding behind frameworks instead of making judgment calls.

The goal of the role is not to centralise ownership inside the People function.

We expect PBPs to strengthen leadership capability, improve decision quality, and help leaders become more effective and self-sufficient over time.

We value:

• clarity over ambiguity;
• direct communication over corporate politeness;
• speed with accountability;
• impact over activity.

What we offer

• Hybrid work & flexible schedule
• Medical insurance (+1 coverage option)
• Professional development reimbursement
• Online English classes
• Employee referral bonus program

Recruitment process

• HR Interview
• Leadership Interview
• Final Interview

If you are comfortable working closely with leadership, solving organisational problems, and helping strong teams scale without unnecessary bureaucracy, we’d love to hear from you.
