StarkWare is a fast-growing five-year-old startup that is leading the way in scaling Ethereum. It has built the SaaS platform StarkEx and the permissionless network StarkNet. As Layer 2 solutions over Ethereum, they retain Ethereum’s security while scaling by orders of magnitude. Adoption is fast, and StarkEx today processes more transactions than all other ‘Layer 2’ solutions combined. StarkNet (Alpha) is a decentralized permissionless Validity-Rollup. Both solutions are based on STARKs, a cryptographic system pioneered at StarkWare.

As our Senior Software Engineer in StarkWare, you will design and develop complex high-performance, high-quality software, spanning across algorithms, application logic, and infrastructure.

Our system is built in a microservice architecture that interacts with external systems (such as the blockchain and our partners’ systems) and meets demanding performance, resilience, and security requirements. The code is written mostly in Python, Rust, and in C++ and utilizes continuous delivery and automated testing methodologies.

The right candidate:

• Has at least 3 years of development experience in a high-level object-oriented language (preference for Python and C++).
• Is a University graduate in Computer Science (with a high GPA).
• Has experience building complex, high-scale, high-performance software.
• Is curious by nature and a quick learner.

Ideally experienced with:

• Advanced OOP and design patterns.
• Performance optimizations.
• Linux operating system, its internals, and ecosystem.
• Interaction with NoSQL databases at scale.
• Implementation of services in a microservice architecture.
• Interaction with tools such as Kubernetes, Docker, Kafka, Flask, or similar.
• Algorithm development.
• Cryptographic primitives and protocols.
• Blockchain technologies.
• CI/CD and TDD methodologies.
