At Offchain Labs, we are not just building products — we’re leading a movement.
We are committed to creating a decentralized, secure, and transparent future through blockchain technology. Our mission is to push the boundaries of blockchain innovation and foster a creative, collaborative, and inclusive culture where ideas can come to life. We know that the future of blockchain technology is limitless, and the best way to achieve this is by working with the brightest minds.
We’re looking for thinkers and doers who are eager to embrace new challenges and seek solutions that will push existing boundaries. If you believe in the importance of transparency, trust, and the decentralization of control, and if you’re curious, adaptable, and want to disrupt the status quo, then we want to hear from you.
Why Offchain Labs?
Our team is committed to bridging the gap between the current state of blockchain and its potential. Our flagship product, Arbitrum One, is a dominant force in Ethereum scaling and is trusted by enterprises, developers, and users worldwide. But that’s just the beginning. Our passionate team is constantly building on this success, rolling out innovative tools such as Arbitrum AnyTrust, Arbitrum Orbit, Stylus, BoLD, and Arbitrum Nitro. Offchain Labs also contributes to the Ethereum core protocol with the Prysm consensus client.
Following the successful raising of $3.8M in seed funding in January 2019, as well as $20M in Series A and $100M in Series B funding in 2021, we are looking to expand our team. We invite individuals with a strong interest in blockchain and a talent for approaching problems from unique perspectives to join us in shaping the future of this dynamic field.
As we continue to scale our ecosystem, we are looking for a Founding QA Lead to build and implement quality assurance technology and processes from the ground up. This is a hands-on, high-impact role where you’ll define our QA strategy, develop automation and testing infrastructure, and ultimately build a world-class QA team.
Ensuring the reliability, security, and performance of a blockchain scaling solution is no trivial task. Bugs and vulnerabilities in smart contract execution, rollups, or state proofs can have massive implications. As our first QA Lead, you will establish rigorous, automated testing pipelines that validate the integrity of Arbitrum’s protocol, its developer tooling, and its ecosystem. Your work will directly contribute to the security and trustworthiness of one of the most widely adopted Layer 2 solutions in the Ethereum ecosystem.
What you'll do:
- Build the QA Strategy & Infrastructure
- Define and implement a comprehensive QA strategy for Arbitrum’s core technology, including smart contracts, sequencers, rollup mechanisms, and developer tooling.
- Establish test automation frameworks that validate correctness, security, and performance across OffChain Labs' 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.
- Introduce load and stress testing to measure scalability under high transaction volume.
- Work Cross-Functionally to Embed Quality in the Development Process
- Partner with software engineers, smart contract developers, and DevOps to establish a culture of quality across the engineering organization.
- 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.
- Grow & Lead the QA Organization
- As the QA function scales, hire, mentor, and develop a team of QA engineers, automation engineers, and test developers.
- Define clear quality KPIs and use data-driven insights to improve reliability and user experience.
What you'll need:
- Experience & Technical Skills
- 5+ years in QA engineering, test automation, or software quality leadership roles.
- Strong automation skills, with proficiency in at least one testing framework (e.g., Pytest, Jest, Mocha, Selenium, etc.)
- Deep understanding of CI/CD pipelines and integrating automated testing within DevOps workflows.
- 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.
- Ability to deploy to and administer virtual machines on a cloud infrastructure provider (e.g. AWS, Google Cloud)
- Leadership & Collaboration
- Prior experience leading or mentoring QA engineers.
- Ability to drive process change and influence engineering teams to adopt best practices.
- Passionate 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 performance testing for distributed systems, including load testing and bottleneck analysis.
Perks:
- Remote-first global workforce + soon to open NY office.
- Annual company offsite + team onsites.
- Professional reimbursement program (facilitates industry conference attendance, certifications, and more).
- Medical, dental & vision coverage (US + some other countries).
- 401k retirement plan + company match (US only).
- Wellness stipend.
- Home office set up / ergonomic equipment program.

What is 401(K) plan?
A 401(k) plan is a type of employer-sponsored retirement savings plan that allows workers to save and invest for their retirement on a tax-deferred basis
Contributions to a 401(k) plan are made through payroll deductions and are generally invested in a variety of financial instruments, such as stocks, bonds, and mutual funds
The tax-deferred nature of the 401(k) plan means that the money you contribute to the plan is not subject to income tax until you withdraw it in retirement, which can help you save more for retirement
Many employers also offer matching contributions to their employees' 401(k) plans, which can help boost your retirement savings even more.
