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.

• 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.

• A habit of checking first and replying second.
• Resilience under pressure.
• Attention to detail.

• Experience setting up and working with an AI support chatbot.
• Confident use of Claude.
• Background in marketing or SMM.

We are looking for an experienced full-stack engineer who works primarily through AI tools and can take ownership of features end to end. You will join a German product team building business software and mobile apps for their clients. 

The working language is German: meetings, specifications and client communication are all in German.

This is not a classic "write code all day" role. Most of the implementation is done together with Claude and other AI agents. What matters is that you understand the whole system, ask the right questions, judge whether a solution is good enough, and move tasks forward independently.

What you will do
• Deliver features across backend, web frontend and mobile apps, working mainly through AI coding agents (Claude Code or similar)
• Research unfamiliar parts of the system, evaluate the existing implementation and propose what to change
• Clarify requirements directly with the German team and with the client, including business questions
• Work with databases, REST APIs and integrations with the client's ERP and third-party systems
• Spot problems on your own and resolve them
• Take tasks from ticket to release, including testing and handover

Requirements
• 5+ years of commercial software development
• Real full-stack experience: backend, web frontend and at least some mobile development
• Experience with .NET/C# or the ability to work in it confidently; Node.js, React and React Native are also relevant
• Good SQL skills and experience with REST APIs and system integrations
• Daily hands-on use of AI coding tools (Claude Code, Cursor or similar) in real projects, not only for autocomplete
• German at C1 level or higher; you must be comfortable leading a technical or business conversation in German
• Independence: you find the information you need and do not wait for detailed instructions

What we offer
• Remote work, long-term project with a German product team
• A role where AI-driven development is the standard way of working, not an experiment
