Role
Who you are
- 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, etc.)
- 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 be a team leader & collaborate with various technical and non-technical roles
- Ability to drive process change and influence engineering teams to adopt best practices
- Passionate about open-source, decentralization, and blockchain technology
Desirable
- 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
What the job involves
- As we continue to scale our ecosystem, we are looking for a Senior Quality Engineer to build and scale automated testing frameworks for our Engineering teams
- This is a hands-on, high-impact role where you’ll implement our QA strategy, develop automation and testing infrastructure, and help us expand our 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 part of our QA team, 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
- Refine and implement the QA strategy for our 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 ProcessPartner 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
Our take
The Ethereum blockchain has seen a surge in activity over the past year or so - but, much to users' frustration, its transaction volume has failed to scale accordingly, leading to hefty gas fees and slow transaction times. Offchain Labs is one of a few players developing Layer 2 rollup solutions, and its Arbitrum rollup has gathered substantial momentum and support in a relatively short time.
Offchain Labs’ Arbitrum claims to offer all the benefits of a rollup - less costly, more efficient - without compromising on security. It is, at the time of writing, the only scaling solution for Ethereum that has working fraud proofs, and at the end of 2021 was dominating the layer 2 rollup market share.
This kind of high profile and superior efficacy determines a successful blockchain technology. With Offchain Labs’ leadership pedigree, it’s no surprise the company is leading rollup innovation efforts. This sector, however, moves at lightning speed—and the competing ZK rollups are by no means out of the picture just yet.
