Top Remote Blockchain QA & Test Engineering Jobs

Lead design and operation of test infrastructure at scale: test orchestration, smart selection, parallel sharding, flaky-test detection, observability, SLOs, and on-call. Define technical strategy, drive cross-team projects, mentor engineers, and reduce test feedback time to accelerate engineering velocity.

Lead backend QA efforts across the SDLC: design and execute test plans and automation, validate APIs, databases and distributed services, track defects, and improve test strategy to reduce manual effort.

Validate and test blockchain and Web3 products across the development lifecycle: create and run test plans, validate smart contract and wallet interactions, test APIs and web platforms, track and verify bugs, collaborate on releases, and improve automation, reliability, performance, and security.

Remote QA Engineer responsible for manual testing and ensuring quality of web and mobile applications. Tasks include web application testing, using Linux command line, SQL queries, bug tracking, load testing, and writing automated tests in Java.

Design, implement, and maintain automated test suites validating frontend flows, backend APIs, and on-chain execution. Build deterministic tests for order lifecycle, slippage, fees, and state reconciliation; run tests in local chain/testnet environments; integrate with CI/CD; triage failures and collaborate with engineers to improve testability and ensure high-confidence releases.

Design and execute comprehensive test plans for dApps and smart contracts, perform unit/integration/end-to-end testing, run security audits and vulnerability assessments, automate tests within CI/CD pipelines, monitor quality metrics, debug issues, and collaborate with developers and product managers to ensure reliable DeFi/EVM-compatible applications.

As a Manual QA Tester, you'll execute manual test cases across web and mobile, run regression tests, log defects, and support exploratory testing while collaborating with QA Leads and developers.

As an Automation QA Engineer, you'll design and implement test frameworks for Oracle projects, focusing on automation testing for APIs and web interfaces, collaborating with development teams to identify and resolve defects.

Design and execute test plans and strategies, perform functional/integration/regression/exploratory testing, validate end-to-end wallet and cross-chain transaction workflows, document and track defects, build and maintain automated test suites, collaborate with engineers to reproduce/debug issues, and improve QA processes and release readiness.

Build and maintain automated test suites for smart contracts and UIs, integrate testing into development, track bugs, improve frameworks, and ensure test coverage for new features.
