QA Engineer
Description

[Edge & Node] stands at the forefront of web3 innovation, envisioning a world driven by individual autonomy, shared self-sovereignty, and boundless collaboration. Established by the minds behind [The Graph], our mission is to establish The Graph as the unshakable foundation of open data on the internet. Through the standardization and incorporation of subgraphs across industries, The Graph has become the premier means of organizing and accessing blockchain data. With expertise in open-source software, tools, and protocols, we empower builders and entrepreneurs to create groundbreaking applications with next-generation digital infrastructure.

Our principles guide us in shaping the future, advocating for a decentralized internet devoid of concentrated power. We strive for consensus-driven truth rather than authoritarian rule and prioritize censorship resistance to uphold our vision of an information age free from single-entity control. By embracing open-source values, we challenge the status quo of web2 and emphasize transparency and collaboration as catalysts for true innovation. We envision a permissionless future where central gatekeepers are a thing of the past, transitioning from trusting intermediaries to trustless systems enabled by smart contracts.

The Product Engineering team, known for its dynamism and collaboration, focuses on developing and enhancing user-facing products with meticulous attention to detail. From creating responsive front-end interfaces to architecting scalable back-end solutions, the team possesses a diverse skill set to tackle complex challenges with excellence.

We are currently in search of a skilled QA Engineer to join our team. We seek someone who is customer-centric and detail-oriented, capable of identifying edge cases and diagnosing issues effectively to uphold high standards of reliability and quality across our products.

Daily Responsibilities:

  • Perform manual testing for new features and bug fixes.
  • Evaluate and prioritize reported issues.
  • Develop automated tests to enhance product quality.
  • Establish processes and frameworks to improve coding standards.

Desired Qualifications and Skills:

  • A bachelor's degree in Computer Science, Engineering, or a related technical field, or equivalent practical experience.
  • Strong communication and writing abilities.
  • Proficiency in JavaScript or another scripting language.
  • Experience with SQL.
  • Familiarity with Web3 technologies.

About The Graph:

The Graph serves as the indexing and query layer for web3, facilitating developers' creation of open APIs called subgraphs for querying applications via GraphQL. The platform supports data indexing from various networks such as Ethereum, NEAR, Arbitrium, and more to cater to diverse blockchain needs. Over thousands of subgraphs have been deployed to date for prominent applications like Uniswap, Synthetix, and many others.

Developers can leverage The Graph to efficiently present blockchain data and deploy subgraphs either through Subgraph Studio or explore existing ones within the Graph Explorer. The Graph community welcomes developers to participate as Indexers, Curators, and Delegators on the mainnet and engage in technical discussions through various platforms like Telegram, Discord, Twitter, and more.

[The Graph Foundation] oversees The Graph Network with support from various entities within The Graph ecosystem including Edge & Node, StreamingFast, and others.
