We're building a prediction-markets and order-book trading platform where prices move in real time and real money changes hands on every trade. We're looking for a QA Engineer to own the quality of that product end-to-end, from order entry and live market feeds to wallet flows, deposits, and settlement. You'll be the person the team trusts to say whether a release is ready, and the one who finds the bug before a user's balance does. If you like breaking things where correctness and money matter at the same time, this is that kind of product.
 

The work is mostly manual testing, scripts and automated smoke suites. You'll spend time near the most interesting parts of the system: order handling, real-time feeds, wallet flows, and the trading experience itself.
 

Technical Stack

- Product: React + TypeScript front end, Node.js + NestJS back end
- Real-Time: WebSockets / SSE, live market and order-book feeds
- Database: PostgreSQL, Redis
- Messaging: Kafka
- Web3: EVM chains, wallets (MetaMask, WalletConnect), testnets, block explorers
- Testing: browser devtools, Postman / curl, Playwright
- Scripting: TypeScript or Python
- Observability: Grafana, logs, and metrics
- Version Control: Git
 

What You'll Do

- Own quality end-to-end: join product discussions early, decide what needs testing, and sign off on releases.
- Test the money paths first: order placement, partial fills, positions, market resolution, payouts, deposits, and withdrawals.
- Test wallet and on-chain flows: connecting, approvals, gas, pending / stuck / replaced transactions, and chain switching.
- Verify below the UI: check balances and settlements against the database, inspect API and WebSocket traffic, and trace issues through logs.
- Script what you repeat: seed markets and test data, call APIs directly, and fire concurrent or duplicate requests to find races.
- Keep a small automated smoke suite healthy so every deploy gets a fast first check.
- File bugs a developer can act on immediately: clear steps, expected vs actual, request IDs or tx hashes, and logs.
 

What We're Looking For

- 2+ years of QA experience
- Strong exploratory testing with a risk-first mindset: you go after what can lose money before what looks wrong.
- Hands-on crypto experience as a user: wallets (MetaMask, WalletConnect), testnets, gas, approvals, and block explorers. You can tell a stuck transaction from a failed one.
- Trading basics: limit / market orders, partial fills, maker / taker, and how a prediction market resolves and pays out. You can work out the expected result before checking the UI.
- Comfortable with API testing (Postman / curl), browser devtools including WebSocket traffic, and SQL for checking data.
- Can write scripts in TypeScript to automate test data, API calls, and concurrency checks.
- Proficient with AI-assisted work: you use AI tools (Claude Code, Cursor, ChatGPT, and similar) daily to design test cases, write scripts, and triage logs, and you catch it when they're wrong. This is part of how we work day to day.
- Sound judgment, you know what blocks a release and what can ship with a ticket, and you raise questions only after doing your own homework.
 

Nice to Have

- Playwright or Cypress beyond the basics.
- Hands-on use of Polymarket, Kalshi, a CEX, or a perps DEX.
- QA on trading, fintech, iGaming / sportsbook, or other real-money / real-time systems.
- Load or concurrency testing
- Reading smart-contract test output
 

How We Work

- Small, flat team with a short path from idea to production.
- You own quality, not just test execution, and have a genuine say in how we ship.
- Open feedback, shared code, low ego.
- Developers own their unit tests; you own the bigger picture of what's covered and what's at risk.
 

What We Offer

- Fully remote work (Europe / Ukraine time zone).
- Competitive salary.
- Flat company structure: no bureaucracy.
- Opportunities for professional growth.
- Work-life balance with flexible working hours.
- Access to various learning resources and development programs.
- 20 days of vacation time.
- 5 illness days.

About product
Our product is an AI marketing service for solo founders and small teams. Our customers are English-speaking founders from all over the world. They reach us through the website chat (Crisp) and the support inbox. An AI agent handles the first line. A human steps in where a decision, hands-on help or an account check is needed.
We are looking for a Support Manager to own this second line end to end: from understanding the request to the customer reply and the ticket for engineers.
 

What you will do

• Handle customer conversations in Crisp and the support inbox in English. Reply fast, short and to the point, in one consistent company voice.
• Find the real cause instead of repeating what the customer said. Before replying, check the account in our internal tools.
• Bugs and feature requests: reproduce the issue, separate a bug from a product misunderstanding, describe the symptom and environment briefly, open a ClickUp ticket and tag the team in Slack. Get back to the customer once it is fixed.
• Manual account operations.

Tools we work in: Claude, Crisp, Stripe, ClickUp, Slack, Clerk, internal admin panel, Gmail.
 

What we expect

• 1+ year in customer support for a SaaS or another online product.
• Written English at B2 level.
• A habit of checking first and replying second.
• Resilience under pressure.
• Attention to detail.
• Ability to work independently.
• Understanding of how social networks work (Reddit, X, Facebook, Instagram, Threads) at the level of an active user: connecting accounts, limits, bans, the difference between a page and a group.

Nice to have

• Experience with Crisp, Intercom, Zendesk or a similar helpdesk.
• Experience setting up and working with an AI support chatbot.
• Confident use of Claude.
• Background in marketing or SMM.
• Basic understanding of how a web product works: what logs are, how to record a bug video, how to explain a problem to a developer.

What we offer 

• Health Insurance.
• GYM.
• English classes.
• 22 days off and 12 sick days.
• Paid national holidays.
• Teambuilding twice per year.

NuxGame is a B2B iGaming technology provider. We deliver turnkey casino and sportsbook platforms, game aggregation, and sweepstakes products to operators worldwide, across four product lines: Turnkey Traditional, Sweepstakes Turnkey, Game Aggregation, and Sweepstakes Game Aggregation.

Our customers are operators. Their back office teams work in our platform every day, and their players use it every time they deposit, verify their identity, or withdraw.

We are looking for a Product Manager to join our Finance Team. You will own everything on the platform that touches money, player identity, and player protection—spanning seven product domains with one dedicated engineering team behind you.

What You Will Do

• Payments and PSP
  • Own the payment roadmap across all four product lines and decide what gets built, what gets configured, and what gets refused.
  • Own the internal payment gateway as a product: integration contract, provider onboarding, error handling and retries, logs, and the tooling support uses to investigate a stuck transaction.
  • Own the technical and product side of PSP relationships and work with our PSP Manager, who owns commercial terms and provider selection.
  • Drive deposit and withdrawal conversion: cashier UX, method visibility and ordering, error minimisation, hosted versus platform side flows, retry and cascading logic.
  • Own crypto and Web3 coverage: networks, confirmations, on ramp providers, wallet based authorisation and deposits.
  • Shorten the time it takes to launch a new provider by standardising the integration, so a new PSP becomes configuration rather than custom development.
• Fraud, KYC and Compliance
  • Own the fraud and risk engine: rules and thresholds, risk scoring, verification flows, duplicate account and bonus abuse detection, manual review load.
  • Own third party KYC and AML integrations end to end, from provider evaluation and platform requirements through rollout to operators.
  • Turn licensing and jurisdictional requirements into configurable platform capability instead of per operator custom work.
  • Hold the balance between fraud prevention and conversion, and defend where you put the threshold.
• Auth and Identity
  • Own registration and login as a conversion product, including social and Web3 registration.
  • Own the relationship between authentication and verification: what a player can do before KYC, what unlocks after it, and how that differs by jurisdiction and by operator.
  • Own back office authentication, permissions, and audit logs as an operator facing product.
• Segmentation
  • Own segmentation as a shared service: how segments are defined, evaluated, and consumed across payments, limits, verification, and reporting.
  • Make it usable by operators without engineering involvement: rule builder, preview and validation before a segment goes live, predictable behaviour when several segments match one player.
  • Own the cost side of it: evaluation performance on large player bases and what happens when a segment changes mid-session.
• Reporting, Limits and Responsible Gambling
  • Own operator facing financial reporting, dashboards, and export tooling.
  • Own the limit framework (deposit, loss, wager, session) and geo blocking as jurisdiction aware, operator configurable capability.
  • Own the responsible gambling toolset and make sure it satisfies the licences our operators hold.

What We Expect From You

• You own the roadmap for your domains and you defend it. Prioritisation is your call to make and to explain, not something you escalate by default.
• You write specifications that an engineer can build from without a business analyst in between: scope and non scope, flows, edge cases, dependencies, acceptance criteria.
• You work with data yourself. You define the metric, pull the number, and check it before you act on it.
• You go deep on the technical side. You read API documentation, review integration contracts, and hold your own in a discussion with engineers.
• You design for many operators at once. Every decision is a decision about configuration, defaults, and backward compatibility, not about a single customer.
• You close the loop after release. A feature that shipped and moved nothing is not a delivered feature.

Requirements

Must Have

• 5+ years in product management, with at least 3 years owning payments, fraud and risk, or financial products in iGaming, fintech, or payments.
• Hands on experience with PSP and payment aggregator integrations: REST APIs, request and response construction, webhooks and callbacks, idempotency, status and error mapping, reconciliation.
• Practical understanding of the trade offs between hosted payment pages, iframe, and fully platform hosted cashier flows, including where PCI scope, conversion, and support load land in each.
• Experience with several payment method families: cards, e-wallets, bank transfer and local rails, vouchers, and crypto (networks, confirmations, on ramp providers).
• Experience integrating KYC and AML providers, and owning or building a rule based fraud or risk engine.
• Experience with rule based configuration and player segmentation: defining segments, resolving conflicts between overlapping rules, and giving business users a safe way to change them without a release.
• Working knowledge of the regulatory requirements affecting deposits, withdrawals, KYC, and responsible gambling in at least two or three jurisdictions.
• Data fluency: deposit success rate, approval rate by provider and method, withdrawal processing time, chargeback rate, verification funnel conversion. You can pull these yourself.
• B2B product experience. Our users are operators and their back office staff, not only end players.
• Structured written communication in English. Russian or Ukrainian for internal team communication.

Nice to Have

• Experience in a multi tenant white label platform serving dozens of operators at once.
• Sweepstakes or social casino experience, where purchase and redemption flows differ from classic deposit and withdrawal.
• Experience with payment orchestration platforms, smart routing, and cascading.
• Experience with Metabase or a comparable BI stack, and enough SQL to validate a number.
• Practical use of AI tooling in the product workflow for discovery, documentation, and analysis.

What We Offer

• Full ownership of a product area that directly moves revenue for dozens of operators, with a dedicated engineering team behind it.
• A direct line to the CPO and to top management. Decisions here take days, not quarters.
• Remote work with a distributed team, or an office in Limassol if you prefer one.
• Competitive salary, flexible hours, and paid time off.
