About INQUD

INQUD is a crypto payment infrastructure for businesses. We build products that allow companies to accept and send crypto payments: on-ramp, off-ramp, mass payouts, recurring payments, and a full merchant backoffice.

We are a small, tight-knit product team that has been working together for 3–6 years with zero turnover. We ship fast, iterate quickly, and don’t hide behind processes — everyone owns their work end-to-end.

Tech stack: Node.js (backend), React (frontend), Kotlin, PostgreSQL, ClickHouse, AWS, Kubernetes, blockchain integrations (EVM, Solana, TRON), Sumsub (KYC/AML), Grafana, DataDog.

The Role

We’re looking for a QA Engineer who wants to build quality from scratch — not just close tickets. You’ll be the person who brings structure, automation, and a quality mindset to a fast-moving fintech product.

This is not a maintenance role. This is a greenfield opportunity: there’s an existing test suite that needs to be brought into CI/CD, a product with complex financial flows that needs proper coverage, and a team that will give you full ownership and trust.

Prove yourself — and there’s a clear path to QA Lead within 6–12 months.

What You’ll Do

• Own the entire QA process: manual testing, automation, API tests, performance testing, release quality
• Build and maintain an automated test framework (you choose the stack — we’ll support you)
• Integrate automated tests into CI/CD pipeline — this is priority #1
• Design and execute API tests for complex financial flows (deposits, withdrawals, AML checks, refunds)
• Set up and run performance/load testing for payment processing endpoints
• Define test strategy: what to automate, what to test manually, risk-based prioritization
• Participate in sprint planning, estimate QA effort, flag risks early
• Work directly with 2 backend and 2 frontend engineers, PO, and Head of Engineering
• Improve QA processes with minimal disruption — evolve what works, fix what doesn’t

Must Have

• 5+ years of QA experience (manual + automation)
• Hands-on experience with at least one E2E automation framework (Playwright, Cypress, Selenium, or similar)
• Strong API testing skills (Postman, REST Assured, or code-based approach)
• Experience integrating tests into CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins, or similar)
• Understanding of test strategy: when to automate, when not to, risk-based testing
• Fintech or payments domain experience (“transaction stuck in pending” needs no explanation)
• Crypto/blockchain domain knowledge (wallet flows, AML, on-chain transactions, payment processing)
• AI-native approach to QA: you use AI tools daily for test generation, API contract analysis, exploratory testing hypotheses, and log triage
• Fluent Russian (team communication language)
• English: reading documentation, technical communication

Nice to Have

• Performance/load testing experience (k6, JMeter, Gatling, or similar)
• Basic security testing knowledge (OWASP Top 10, common fintech vulnerabilities)
• Experience in small product teams (not just large enterprise or outsource)
• Diverse background: worked in different environments (startup, product, outsource) and understands trade-offs
• Familiarity with monitoring/observability tools (Grafana, DataDog)

Who You Are

This section is as important as technical skills. We’ve learned from experience that culture fit matters more than a perfect CV in a small team.

• You adapt to existing processes before trying to change them. Your first month is about listening and understanding, not restructuring.
• You’re autonomous but not isolated. You don’t need micromanagement, but you communicate proactively when something is off.
• You’re ambitious but not political. You want to grow to Lead because you want to build great QA — not for the title.
• You’re flexible in your approach. You don’t come with “the one true framework” — you assess the situation and propose what fits.
• You finish what you start. Initiatives that live forever in “in progress” are not achievements.
• You’re comfortable in a team where everyone is a friend, not just a colleague. We care about each other and expect the same.

What We Offer

• Competitive salary (B2B contract), based on experience
• Fully remote — work from anywhere (we prefer UTC+1 to UTC+5 overlap for team sync)
• Stable product team — zero turnover, everyone has been here 3–6 years
• Real ownership — you own QA end-to-end, no bureaucracy
• Clear growth path to QA Lead within 6–12 months based on results
• Direct access to PO and Head of Engineering — no layers of management
• Modern fintech/crypto product with real users and real money at stake

About the role

We are looking for a Game Artist who will bring casino games to life across multiple verticals: crash games, RNG table games, live dealer experiences, and slots. You are a "visual visionary" who understands that in iGaming, art is about "visualising the win" and building player trust through high-quality aesthetics. You will work within our specialised AI-First Art Production pipeline, using advanced tools to accelerate ideation while maintaining the "premium-by-default" quality. We value the final result and your creative thinking more than a specific software stack, as long as your output seamlessly integrates into our Figma-based workflow.

What you’ll do

•Asset Creation: Design and render high-quality assets, including character sets, reel symbols, and backgrounds tailored to the game's theme.

•Branding & Marketing Art: Create compelling game logos and game covers (store tiles/thumbnails) that capture the player's attention in crowded lobbies.

•AI-First Exploration: Follow our workflow: start with AI generation for research and ideation, then use our decision tree to polish, overpaint, or finalise the output to reach professional standards.

•Layout & Composition: Develop visual concepts for both Landscape and Portrait orientations, ensuring proper "safe area" management for mobile and desktop.

•Style Fidelity: Maintain strict adherence to defined style attributes (outlines, gradients, shading, perspective) while aligning visuals with the game’s core mechanics.

•Figma-Centric Handoff: Ensure all final assets are correctly uploaded to the Figma project file in both raster and vector formats, ready for the design and dev teams.

• Strong Portfolio: Case studies showing "game-ready" asset sheets (symbols, environments) with a focus on visual hierarchy and readability at small scales.

• AI Tool Literacy: Proficiency in using AI tools (Freepik, Midjourney, Gemini, or GPT) for rapid prototyping and assets like Recraft for efficient raster-to-vector conversion.

• Technical Knowledge: Understanding of texture atlases, 9-slice guides, and asset optimisation for web/mobile performance.

• English B1+: Ability to join reviews, discuss visual feedback, and document asset libraries.

Mindset & Soft Skills

• "Premium-by-Default" Mindset: A high internal quality bar for detail, logic, and visual consistency.

• Efficiency: Ability to work within a timeboxed "AI-First" exploration phase before committing to manual

adjustments.

• Responsibility: Taking ownership of the visual identity for game assets, the game logo, and the game

cover.

Nice to have

• Previous experience or basic understanding of Game UI/UX.
