About
At Offchain Labs, we aren’t just building products; we’re leading a movement. As pioneers in blockchain scalability and security, we’re at the forefront of transforming how the world interacts with decentralized applications, laying the foundation that will define the next generation of digital commerce, governance, and human interaction.
At the center of this vision is our people. Our team is made up of thinkers and doers that embrace new challenges and seek solutions that push existing boundaries. If you’re energized by solving unprecedented problems and believe in the role that decentralized systems will play in creating a more equitable digital future, then we want to hear from you.
Offchain Labs is setting the pace for the entire Ethereum ecosystem. We built the Arbitrum stack that powers Arbitrum One, the most widely adopted Ethereum scaling solution today. Arbitrum’s ecosystem is growing with hundreds of projects and dApps. Over 100 different teams have used Offchain Labs technology to build their own Arbitrum chains. Major players, including Robinhood, BlackRock, Ethena Labs, Securitize, Aave, and Apechain, all use the Arbitrum stack.
Arbitrum’s thriving ecosystem wouldn’t exist without our advanced technology stack: Arbitrum, Prysm, ZeroDev. These tools are actively reshaping what’s possible on Ethereum and advancing its core infrastructure. We’re backed by $124 million in funding and have demonstrated consistent execution with billions in secured value, thousands of supported projects, and infrastructure processing millions of transactions seamlessly.
The Role:
Build and scale automated testing frameworks across our engineering teams, implementing our QA strategy, developing automation and testing infrastructure, and expanding our QA team.
Establish rigorous, automated testing pipelines that validate the integrity of Arbitrum’s protocol, its developer tooling, and ecosystem, directly contributing to the security and trustworthiness of one of the most widely adopted Layer 2 solutions.
What you’ll do:
Refine and implement the QA strategy for engineering teams.
Establish test automation frameworks that validate correctness, security, and performance across Platform Engineering’s entire stack.
Integrate QA into the CI/CD pipeline to ensure rigorous pre‑deployment validation of protocol updates and software releases.
Develop fuzzing, property‑based testing, and other advanced verification techniques for smart contract security.
Execute load and stress testing to measure scalability under high transaction volume.
Work cross‑functionally to embed quality in the development process, partnering with software engineers, smart contract developers, and DevOps to establish a culture of quality.
Collaborate with researchers and external auditors to automate vulnerability detection and regression testing.
Work closely with developer relations to ensure that SDKs, APIs, and documentation are well‑tested and reliable for the growing Arbitrum developer ecosystem.
What you’ll need:
3+ years in QA engineering, test automation, or software quality roles.
Strong programming language skills in at least one language such as Go, Rust, JavaScript, TypeScript, Python, Java, or similar.
Strong automation skills, with proficiency in at least one testing framework (e.g., Playwright, Cypress, Pytest, Jest, Mocha, Selenium).
Deep understanding of CI/CD pipelines and integrating automated testing within DevOps workflows.
Ability to deploy to and administer virtual machines on a cloud infrastructure provider (e.g., AWS, Google Cloud).
Ability to lead a team and collaborate with various technical and nontechnical roles.
Ability to drive process change and influence engineering teams to adopt best practices.
Passion about open‑source, decentralization, and blockchain technology.
Nice to have:
Experience building QA processes from scratch in a fast‑paced, engineering‑driven environment.
Experience with blockchain‑based, Web3 products and crypto wallets.
Experience testing complex web and mobile applications, either manually or through automation.
Familiarity with blockchain, Ethereum, and Layer 2 scaling solutions (or strong willingness to learn).
Security mindset – familiarity with fuzzing, property‑based testing, and formal verification is a plus.
Experience with performance testing for distributed systems, including load testing and bottleneck analysis.
Prior experience mentoring QA engineers.
Perks:
Remote‑first global workforce + NY office.
Annual company offsite and team onsite events.
Professional reimbursement program for industry conference attendance, certifications, and more.
Medical, dental, and vision coverage (US and some other countries).
401k retirement plan with company match (US only).
Wellness stipend.
Home office setup/ergonomic equipment program.
This role cannot be performed in California or Colorado.
