职位要求 / 描述

At Offchain, 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. We're laying the foundation that will define the next generation of digital commerce, governance, and human interaction. This involves tackling real-world challenges that come with scaling blockchain technology, without compromising on its core principles: decentralization, security and transparency.    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.    Why Offchain?   Offchain 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 that exists today.   Arbitrum’s ecosystem is undergoing tremendous growth with hundreds of projects and dApps on Arbitrum One today. Over 100 different teams have used Offchain technology to build their own Arbitrum chains. Major players in the space, Robinhood, BlackRock, Ethena Labs, Securitize, Aave, and Apechain are all using the Arbitrum stack.   Arbitrum’s thriving ecosystem wouldn’t exist without our advanced technology stack. Arbitrum, Prysm, ZeroDev. These aren’t just product names. These are tools that are actively reshaping what's possible on Ethereum and advancing its core infrastructure.   To top it all off? We’re backed by $124 million in funding. We’ve demonstrated consistent execution with billions in secured value, thousands of supported projects, and infrastructure processing millions of transactions seamlessly. Who You Are： • Eager to dive into blockchain technology, even if it’s new territory • Enjoy solving infrastructure problems in unconventional ways and thinking beyond standard patterns • Use tools like k9s or ArgoCD for speed and abstraction, but comfortable dropping into YAML, logs, or low-level debugging when things go sideways • Experienced with GitOps-style systems and treating both infrastructure and application delivery as code • Have scaled deployment automation using patterns like ArgoCD ApplicationSets or similar tooling • Curious about how things work under the hood and not satisfied with surface-level fixes • Comfortable in Linux, fluent in shell scripting, and productive in languages like Python or Go • Comfortable operating within a cloud platform (e.g., AWS, GCP, Azure), with a strong understanding of the underlying components making it easy to adapt to or migrate across providers • Participated in an on-call rotation, responding to incidents, troubleshooting under pressure, and driving postmortems to improve system reliability over time • Design systems with security in mind, applying principles like least privilege and threat modeling • Bring a strong technical foundation, excellent problem-solving skills, and a genuine commitment to high-quality work • Take ownership, collaborate openly, and contribute to a culture of clarity, curiosity, and continuous improvement What You've Done： • Operated production Kubernetes clusters and built scalable, declarative infrastructure using Terraform or similar tools • Deployed and maintained Kubernetes environments, managed system components, and troubleshot applications running on the platform • Designed CI/CD workflows with ArgoCD, GitHub Actions, CodeBuild, or similar tools, covering both infra and app deployments • Designed and operated observability systems using time-series metrics, logs, and dashboards with tools like Prometheus, Loki, Mimir, Grafana, and CloudWatch • Diagnosed tough networking and storage issues across complex, distributed systems • Implemented secure-by
