About KriptoK

KriptoK is a non-custodial multichain wallet built for the next generation of direct-to-consumer blockchain products. We are making swaps, dApps, tokenized assets, vaults, and onchain finance easier to use across high-growth markets. The product spans multiple ecosystems including Bitcoin, Ethereum, Solana, Sui, BNB Chain, Base, Arbitrum, Tron, HyperEVM, Avalanche, and more. As we scale, quality, reliability, and user trust are critical. We are looking for a QA Engineer who can help us test deeply, catch issues early, and make sure KriptoK feels fast, reliable, and polished before features reach users.

What you’ll work on

• Test mobile app features across iOS and Android, including wallet creation, onboarding, swaps, sends, receives, dApps, WalletConnect, token discovery, and transaction flows.
• Perform detailed regression testing before each release.
• Test integrations across multiple chains including Solana, EVM networks, Sui, Tron, HyperEVM, Avalanche, Bitcoin, and others.
• Identify, reproduce, document, and track bugs clearly for the engineering team.
• Test edge cases around failed transactions, network changes, token visibility, gas, slippage, wallet permissions, signing flows, and app performance.
• Work closely with product, design, and engineering to improve user experience and release quality.
• Help build QA checklists, release processes, test cases, and internal testing standards.
• Support testing for new product launches, growth campaigns, rewards, vaults, tokenized assets, and event-based features.

What we’re looking for

• Experience testing mobile apps, ideally in crypto, fintech, wallets, exchanges, or other high-trust consumer products.
• Strong attention to detail and ability to think like a real user.
• Comfortable testing across different devices, operating systems, chains, and transaction types.
• Ability to write clear bug reports with screenshots, recordings, reproduction steps, expected behavior, and actual behavior.
• Strong ownership mindset. You should care deeply when something feels slow, unclear, broken, or risky.
• Comfortable working in a fast-moving startup environment.

Nice to have

• Experience with blockchain wallets, DeFi, swaps, bridges, dApps, or WalletConnect.
• Familiarity with tools such as TestFlight, Firebase, Jira, Linear, GitHub, Sentry, Postman, or analytics platforms.
• Basic understanding of transaction hashes, block explorers, RPC issues, token contracts, and wallet permissions.
• Automation testing experience is a plus, but not required.

Why join KriptoK

• You will play a direct role in making KriptoK feel trustworthy, premium, and easy to use. This is not just button-clicking QA. You will help protect the user experience of a product operating across some of the most exciting blockchain ecosystems in the world.
