The Discipline â¤ď¸
Our engineering discipline builds the technology that enables MoonPay to learn quickly and scale easily. We organise in small cross-functional squads of 4-6 engineers and an embedded Product Manager, Product Data Analyst and QAE. We currently have squads across Crypto / NFT / Payments / KYC / Core Product and others. Weâre pragmatic and believe in having a fluid structure, this means people can move between teams or specialise.
Tech Stack đť
- Typescriptas our programming language of choice
- Node.jsas our backend platform
- TypeORM,TypeDI,TypeGraphQLandrouting-controllersas our backend libraries
- Postgresas our core database
- Redisfor caching
- Bullto manage background tasks
- Herokuto host our backend services
- SomeAWSservices to send emails, store objects and manage private keys
- New Relic,CoralogixandSentryfor logging and monitoring
- GitHubto manage our source code
- ethers.jsto interact with different EVM compatible blockchains
- Jestto run our tests â
What youâll do đ
- Take ownership of MoonPayâs native crypto stack. This is a new area for us and youâll be owning the architecture and implementation from day one.
- Build lightweight hot wallets to handle Ethereum key generation and outbound transfers to our customers.
- Work with Ethereum layer 2 scaling solutions like Polygon (Matic) and zkSync to offer layer 2 ETH assets to our customers.
- Work on other innovative blockchains where few have ventured such as Flow.
- Work with Product Managers to come up with the best solutions and implementation plans for new features or changes to existing ones.
- Contribute to the estimations, planning and execution of projects, features, and integrations.
- Write fully tested, high quality and performant code.
As a Senior you will be expected to:
- Mentor and coach Engineers.
- Champion the writing of high quality code.
- Contribute to our overall approach and standards within the Engineering discipline.
- Lead squads from an Engineering perspective, partnering closely with Product Managers.
You should apply if â
- Youâve built production-grade cryptocurrency wallets.
- You have extensive engineering experience at leading startups or fast growing tech companies focusing on the crypto stack.
- You are confident in developing, releasing and maintaining server applications in a fast paced, iterative environment.
- You have either had experience with Solidity, Ethereum and Bitcoin or are confident you can cross train and up skill quickly.
- Youâve got a deep understanding of blockchain fundamentals, theories, principles and best practices.
- Bonus points if you make open-source contributions or have experience in Blockchain, Web3 or FinTech.
Researchhas shown that women are less likely than men to apply for this role if they do not have solid experience in 100% of these areas. Please know that this list is indicative and that we would still love to hear from you even if you feel you only are a 75% match. Skills can be learnt, diversity cannot.
We promote a diverse and inclusive culture at MoonPay.
Logistics đ
Unfortunately, we are unable to offer visas of any kind at this time!
Our interview process takes place on Zoom and tends to consist of the following stages:
- Recruiter call (20-30 minutes)
- Initial screen (30-45 minutes)
- Remote take-home task
- Final interview (2 hours)
Please let us know if you require any accommodations for the interview process, and weâll do our best to provide assistance.
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.
