This role is ideal for engineers who have a passion for test automation, load testing, and identifying root causes of bugs to enhance blockchain performance and scalability. If you’re excited about solving unique challenges in the Web3 space and driving innovation in blockchain testing methodologies, we want to hear from you! What You'll Be Doing:

Analyze bug tickets, debug code, and identify the root cause of errors across the Shardeum platform. Design, develop, and maintain test automation frameworks and reusable test scripts to validate core functionality, including nodes, consensus mechanisms, smart contracts, and blockchain transactions. Utilize cutting edge AI tools to make testing faster and more efficient (Cursor, Github Copilot, Windsurf, Cline, etc..) Develop and execute load testing scripts to validate system performance under high transaction loads and varying node configurations. Create comprehensive test coverage through functional, integration, system, and regression testing while optimizing test suites and identifying performance bottlenecks. Develop end-to-end (E2E) test cases for complex workflows, ensuring reliability of consensus protocols and smart contract execution. Collaborate closely with development teams to integrate testing into CI/CD pipelines, improve testing workflows, and troubleshoot dependency failures. Build and maintain internal tools to improve developer experience, productivity, and test efficiency. Troubleshoot highly complex automated testing failures using industry-standard frameworks and custom tools, working with developers and backend partners to triage issues and improve E2E reliability. Develop monitoring tools and utilities to track blockchain-specific performance metrics and test results. Participate actively in agile ceremonies, including sprint planning, stand-ups, and retrospectives, to drive testing best practices. Continuously research and adopt innovative tools, frameworks, and testing methodologies to improve quality, scalability, and efficiency of testing processes.

What We're Looking For:

5+ years of experience in Software Engineering experience with a focus on testing. Proficiency in programming languages like TypeScript/JavaScript and Node.js, with the ability to develop robust and reusable test scripts. Ability/desire to write Unit Tests in TypeScript/JavaScript and Node.js Proven ability to analyze and debug complex codebases, troubleshoot multi-tier web architecture issues, and identify root causes of failures. Experience integrating automated tests into CI/CD workflows (e.g., GitHub Actions, Jenkins). Expertise in defining and implementing release, regression, and smoke testing strategies for large, multi-team applications. Experience with white-box testing methodologies to ensure deep validation of internal components. Strong problem-solving and critical-thinking skills, particularly in analyzing blockchain-specific issues. You have a tester mindset, are curious, and excel at designing innovative and interesting test scenarios. You are creative in applying proven tools/test frameworks as well as crafting new solutions to challenging problems. Knowledge of Agile/Scrum methodologies and the software development lifecycle. Excellent verbal and written communication skills for clear bug reporting and collaboration across teams.

We'd Love If You Have:

Experience with testing decentralized applications (dApps), consensus protocols, or blockchain platforms. Experience in running nodes within blockchain networks and monitoring performance metrics. Familiarity with blockchain tools and frameworks (e.g., Web3.js, Hardhat, Truffle). Hands-on knowledge and experience with AI tools (Cursor, Github Copilot, Windsurf, Cline, etc...), and the ability to demonstrate how you utilize them in your day to day. Contributions to open-source projects related to testing, automation, or blockchain. A passion for emerging technologies, including Web3, AI, and distributed systems. Experience using or contributing to the Shardeum open-source repos. Familiarity with blockchain performance benchmarks and profiling tools. Knowledge of the Bitcoin and Ethereum whitepapers.

We are building the infrastructure for Web 3.0.
