About our values

Think deeper: We understand that in order to grow we need to make all our decisions reality-based and change our opinion based on what we learn. We appreciate data coming in various forms – quantitative and qualitative, feedback from users and colleagues, and strong and weak signals.We treat data as the main source for leveraging insights and expect people at every level to have conversations that start with data.

Focus on impact: Results and speed matter. When we are competing to become an A-player in the digital health market, we don’t have the luxury of deliberation. We need to make decisions and changes quickly and, swiftly learn from our mistakes.We prioritize what will have the greatest impact and aren’t distracted by anything else. We create products that benefit users while we are meeting our metrics.

Take ownership: We seek to improve all facets of our company even in ways beyond our job description. We seek and take responsibility for our actions and their impact. We value and set high expectations for our own work so that it can add to the overall quality and innovation results of the team. Each one of us is empowered to make this company a success, take the lead to resolve disagreements and systemic issues.

Push the limits: We encourage our team to explore new ideas, challenge conventional thinking, and continuously improve work. This mindset can lead to breakthroughs in product development, improved operational efficiency, and increased competitiveness in the market. We believe that a culture and mindset of constantly striving to exceed existing standards, boundaries, or expectations that include innovation, experimentation, and a willingness to take risks, can bring us success. We don't accept what someone says as truth if we disagree with it, no matter what authority that person has in the company and express ourselves directly, not through back channels. We challenge ideas, from policy to product decisions, and always seek to understand the reason behind what we do.

Be a Championship Team: As a part of the championship team, you must improve your own performance constantly also know your teammates, their talents and skills and be focused on a common goal and how to achieve it together. We hold each other accountable for our contribution to the shared success or failure, and we constantly look for ways to help our colleagues to improve and for us to perform better as a team. We collaborate within the team in order to compete with challengers in the outside world. We build relationships of trust.

Team & Role Overview

The Open Platform is looking for a QA Lead / Senior QA Engineer with a strong hands-on profile to combine active manual testing with coordination of a small QA function within a product and engineering team. This is not a purely managerial role — the initial focus will be on practical work, deep product immersion, and building solid test coverage for key user scenarios. The team works across multiple products simultaneously, so this role requires strong autonomy, structured thinking, and the ability to maintain quality in a fast-paced environment. Currently, QA operates in a reactive mode, and a key goal is to transition it to a more proactive approach — engaging early, understanding product changes in advance, and reducing risks before release.

We are looking for a QA Lead / Senior QA Engineer with a strong hands-on profile to combine active manual testing with coordination of a small QA function within a product and engineering team. This is not a purely managerial role — the initial focus will be on practical work, deep product immersion, and building solid test coverage for key user scenarios.

What you'll do

• Perform hands-on manual testing of key product scenarios and release changes as a core part of the role.
• Analyze PRDs, requirements, and product updates independently, and define testing approaches throughout the development cycle.
• Engage early in product and engineering processes to contribute beyond final acceptance stages.
• Create and maintain test cases, checklists, and regression scenarios.
• Define testing scope before releases, including decisions on manual vs. automated coverage.
• Coordinate a small QA team: distribute workload, prioritize tasks, and ensure team flexibility.
• Reduce bus-factor risks through knowledge sharing and transparent coverage across products.
• Collaborate closely with engineering, product, and other stakeholders to improve quality and release predictability.
• Gradually introduce process improvements, including earlier QA involvement and better testing practices.
• Maintain a high quality bar without compromising delivery speed.

What we expect from this role

• In the first 3 months — deep immersion into the products and a strong focus on hands-on manual testing.
• Gradual improvement of QA processes, workload distribution, and team cross-functionality.
• Ensuring that all external user touchpoints are properly validated before each release.
• Developing the QA function without drifting into “management for the sake of management.”

Requirements

• 4-6+ years of experience in QA, including strong hands-on experience in manual testing of product scenarios.
• Experience as a QA Lead / Senior QA / QA Coordinator or in a similar role with ownership of a small team while remaining hands-on.
• Willingness to stay highly involved in practical work (approx. 80% manual testing, 20% leadership/process tasks).
• Experience organizing QA processes: test planning, task distribution, prioritization, and reducing single points of failure.
• Ability to work independently with requirements, PRDs, and product changes without constant guidance.
• Experience writing test cases, checklists, test plans, and maintaining regression coverage.
• Solid understanding of SDLC and the QA role across different stages of product development.
• Strong communication skills and ability to collaborate effectively with engineering, product, and other stakeholders.
• High level of ownership, attention to detail, structured thinking, and proactivity.

Nice to Have

• Experience testing web, mobile, SDKs, or developer tools.
• Understanding of how to balance manual and automated testing and make decisions around test automation.
• Experience in fintech, crypto, web3, wallets, developer platforms, or B2B2C products.

Benefits & perks

• Our business is growing at an exponential scale.
• Non-bureaucratic management that focuses on results.
• Regular performance reviews to assess your progress.
• Remote setup with access to our hubs in Dubai, Yerevan, London and Belgrade.
• Compensation for medical expenses.
• Provision of necessary equipment.
• Employees get access to the most advanced AI models via mira.tg.
• 20 working days of paid vacation annually.
• 11 days off per year.
• 14 days of paid sick leave to support your health and recovery when needed.
• Access to internal conferences, English courses and corporate events.
