About Arbitrum

Arbitrum specializes in creating adaptable, scalable blockchain solutions. Currently, decentralized applications (dapps) deployed on general-purpose blockchains face competition from numerous other applications for network resources, which can result in congestion, elevated fees, or even outages.

Our mission is to address this issue. We are developing software that empowers the most innovative blockchain applications to launch their own high-performance blockchains (rollups), allowing these applications to control their ecosystems, scale to millions of users, and deliver an exceptional user experience.

Our operations are based in a collaborative environment.

As a Staff Backend Engineer at Arbitrum, your responsibilities will include:
  • Designing and implementing backend systems to ensure the efficient functioning of Arbitrum's blockchains.
  • Developing secure and scalable crypto-native systems on EVM blockchains, such as indexers or relayers.
  • Taking ownership of new features from initial concept to deployment for Arbitrum's self-service infrastructure platform.
  • Leading data model design, ensuring databases are optimized for performance, scalability, and reliability.
  • Engaging in performance optimization efforts, profiling systems to reduce latency and enhance throughput.
  • Providing technical leadership and mentorship, including delivering constructive feedback and code reviews for junior engineers.
You may be a suitable candidate for this role if you possess:
  • A minimum of 4 years of engineering experience.
  • Proficiency in developing backend services using Go or Typescript.
  • Experience in designing, building, and maintaining robust APIs.
  • A strong capability to design efficient and scalable data models.
  • A solid background in cloud computing platforms, particularly AWS.
  • A keen understanding of security, including threat modeling and secure system architecture.
Preferred qualifications include:
  • Familiarity with modern infrastructure technologies such as containerization, infrastructure as code, and Kubernetes.
  • Knowledge of how blockchains like Ethereum or Bitcoin operate at a fundamental level.
  • Awareness of Ethereum scaling solutions, including sidechains or rollups.
  • Understanding of cryptographic primitives, such as hash functions or digital signatures.
  • Experience in developing Ethereum decentralized applications (dapps).

If you are uncertain about your qualifications, we encourage you to apply. We are committed to finding a place for exceptional candidates, even if you do not meet every requirement.
