Your mission

Take full ownership of quality as a system, not a phase.
You will transform QA from a supporting function into a company-wide quality engineering discipline, driving process maturity, security awareness, and automation-first culture.

What you will actually do:

— Own and evolve QA strategy at the company level:
 define how quality is built, measured, and scaled across all projects

— Lead QA transformation initiatives:
 • move from manual-heavy QA to automation-first approach;
 • eliminate process chaos and introduce predictable, repeatable delivery models;
 • standardize QA practices across teamxs without killing flexibility.

— Embed security into QA processes (not as a checkbox):
 • define security testing standards;
 • integrate basic security checks into SDLC;
 • raise security awareness across engineering teams.

— Own non-functional quality:
 • performance & load testing strategy;
 • data integrity & database testing;
 • reliability for Live systems.

— Build a modern automation ecosystem:
 • define automation strategy across projects;
 • ensure frameworks are scalable, maintainable, and actually used;
 • drive high ROI automation (not “automation for the sake of automation”).

— Scale quality metrics that matter:
 • defect leakage;
 • automation efficiency;
 • team performance and delivery health.

— Build and lead a high-performance QA organization:
 • hire strong engineers, not “manual testers”;
 • grow people into T-shaped quality engineers;
 • mentor leads and shape future QA leaders.

— Partner with Engineering and DevOps to make quality a shared responsibility, not a QA bottleneck

What makes this role interesting:

— You are not “leading QA team” — you are shaping how the company builds software;
— You will work on processes that actually need fixing, not maintaining legacy bureaucracy;
— High level of ownership and decision-making power;
— Direct impact on engineering culture and delivery quality;
— Strong focus on growth and learning (courses, conferences, certifications);
 — Flexible work format (remote / office);
 — Paid vacations (23 business days) and sick leaves;
 — Full transparency on company performance.

We expect you to bring:

— Strong experience as Lead / Staff QA with real ownership of quality processes;
— Proven track record of building or transforming QA practices (not just supporting them);
— Deep expertise in:
 • test automation strategy and frameworks;
 • QA process design and scaling;
 • non-functional testing (performance, reliability, data).
— Solid understanding of security fundamentals in QA;
 (you don’t need to be a pentester, but you know where QA adds value in security)
— Experience working in multi-project / outsource environments is a big plus;
— Ability to operate on both levels:
 • strategic (define direction);
 • hands-on (get into tools, frameworks, problems when needed).
— Strong system thinking: you see QA as part of engineering ecosystem, not isolated function;
— Good technical background:
 • APIs, web, mobile;
 • logs, debugging, observability tools;
 • CI/CD understanding.
— English: Upper-Intermediate or higher.

Awesome if you have:

— Experience implementing OWASP-based practices or security testing workflows;
— Programming experience (Java / JS / Python) for building robust automation;
— Experience with quality metrics systems and data-driven decision making.

THE ROLE

You will be the analytical owner of your product domain- turning data into decisions for Product, R&D, Operations, and Business teams. Day to day, you will work hands-on in SQL and BI tools, partner closely with PMs and engineers, and help shape the strategic direction of the product through evidence.

WHAT YOU'LL DO

• Own all analytical aspects of your assigned product domains.
• Build and maintain reports, dashboards, and metrics, and monitor the integrity and validity of the data behind them
• Use analytical tools, data mining, and business logic to consult the Product team on day-to-day questions and decisions 
• Analyze and optimize products and activities- take part in design and implementation as a key voice in strategic product decisions
• Own and manage multiple data initiatives and projects, both ongoing and ad-hoc
• Define alerts and monitor performance to improve process efficiency
• Provide supporting data to help prioritize new features and initiatives 

• Work closely with Product, R&D, Operations, and Business teams

   

WHAT YOU'LL NEED (must-have)

• 4+ years in a Product / Data / Business / Operations Analyst role in a data-rich environment 
• Current position MUST be an analyst role at a tech company (no finance, banking, or insurance backgrounds) 
• Excellent SQL - daily, hands-on query writing. This is not a role where SQL is occasional; expect to live in it.
• Strong verbal English (B2+ or higher). You will present findings to PMs, engineers, and business stakeholders directly in English every week - fluency matters.
• Excellent communication skills - the ability to deliver the results of an analysis clearly, concisely, and confidently 

• Proven experience using AI tools in your analytics workflow (e.g. ChatGPT, Claude, Gemini, or similar for query generation, data exploration, or summarization)

   

NICE TO HAVE (advantage, not required)

• Hands-on experience with Tableau, Power BI, or Looker
• Experience analyzing datasets via an LLM tool

• Passion for sports

   

WHO THIS IS NOT FOR

• Analysts coming from finance, banking, or insurance -we are looking specifically for tech / SaaS / product backgrounds
• Anyone whose English is below confident B2; this role is stakeholder-facing in English daily
• SQL-light profiles- if you write a few queries a week rather than every day, this role will not fit
