The role
As a core member of the backend engineering team, you will build and maintain major features, through inception, design, implementation, and launch, working closely with product and engineering disciplines across the company. The perfect candidate has an in-depth understanding of distributed systems, blockchain, and hands-on experience architecting and developing existing blockchain smart contract platforms. You will spend the majority of your time on cross-functional self-contained feature teams focused on delivering value to the customer, while other projects will be more internally focused on integrations, scalability, and performance.
Responsibilities
- Participate in the design and implementation of a decentralized protocol for crypto derivatives trading. This includes developing, testing, and deploying the backend and smart contracts needed to do so.
- Design and develop any APIs and/or SDKs required to support trade execution services.
- Own monitoring, alarming, analytics, and reporting on all services you build, ensuring high performance and responsiveness
- Communicate requirements effectively within and across teams
Requirements
- 7+ years of backend engineering experience, ideally building products from ideation to launch with a strong engineering team
- Demonstrable, in-depth knowledge and experience with at least one modern language such as Javascript, Python,Golang, Java, C++
- Proficient in basic cryptography concepts
- Hands-on experience creating upgradeable smart contracts and building on blockchain
- Comfortable working cloud-native AWS infrastructure and/or Kubernetes
- B.S. in Computer Science or a related field (M.S. a plus)
Nice to have
- Deep knowledge of the cryptocurrency ecosystem (BTC, ETH, etc.) and underlying technologies (blockchain, PoW, PoS, etc.)
- Interest and understanding of L1/L2 blockchain technology and ZK-Rollups
What is the meaning of Layer 2?
Layer 2 in the context of cryptocurrency and blockchain technology refers to a secondary framework or protocol that is built on top of an existing blockchain system (the main chain or Layer 1)
The primary purpose of Layer 2 solutions is to solve the scalability and speed issues that many blockchains face, especially those that have become popular and heavily used, like Ethereum
Here are the key aspects of Layer 2 solutions:
- Scalability Enhancement: They help in scaling the main blockchain by handling transactions off the main chain. This reduces the burden on the main chain, allowing for faster and cheaper transactions.
- Types of Layer 2 Solutions: There are various forms of Layer 2 solutions, including state channels, sidechains, plasma chains, and rollups. Each has its own mechanism for interacting with the main chain and handling transactions.
- State Channels: These involve two parties engaging in numerous transactions outside of the main chain, which are then consolidated into a single transaction. This is especially useful for situations where multiple transactions occur between the same parties.
- Sidechains: These are separate blockchains that are connected to the main chain via a two-way peg. They operate independently and can have their own consensus mechanisms but are secured by the main chain.
- Plasma Chains: Plasma chains are similar to sidechains but with a more hierarchical structure. They report back to the main chain regularly and are optimized for mass transaction handling.
- Rollups: Rollups process and store transaction data on a sidechain but post transaction data to the main chain. They come in two varieties: optimistic rollups and zk-rollups, each with its own method of transaction verification.
- Security Considerations: While Layer 2 solutions are generally secure, they can have different security models compared to the main chain. This is an important consideration for users and developers.
- Impact on User Experience: For end-users, Layer 2 solutions can greatly improve the experience by reducing transaction fees and increasing transaction speeds.
- Adoption and Development: Many blockchain projects are actively developing Layer 2 solutions to enhance their networks. This is an ongoing area of innovation in the blockchain space.
