# Senior Quality Assurance Engineer Job Description

We're looking for a Senior QA Engineer to join the API3 Core team. You'll play a key role in ensuring our software is robust and well optimised. You'll have ownership over the testing process, so this is a great role if you're a self-starter.

What you'll be doing:

  • Full cycle testing: designing, documenting and executing manual tests, and scripting automated tests
  • Root cause analysis of bugs, test failures and regression testing thereof
  • Continuous improvement of the testing tools, test coverage, and automated testing environment
  • Performing investigatory tests of unreleased features and experiments to define requirements, behavior and impact
  • Recommending system improvements based on the testing experience
  • Working closely with the engineers and product owners

What skills we need you to have:

  • Senior-level professional QA engineering experience testing back-end services such as APIs, databases, distributed services (non-monolithic) and Solidity smart contracts
  • Good understanding of modern testing tools, frameworks and strategies
  • Enjoy breaking things and solving problems - not just able to find out the 'what', but also the 'why'
  • A technical scripting ability
  • Thoroughness and attention to detail
  • Professional working proficiency in English

You'll be very well qualified for the role if you have some of the following:

  • Scripting proficiency with NodeJS, Bash and/or Python
  • Experience with Blockchain and Ethereum technologies
  • Experience with smart contract security auditing and testing

What you'll be doing:

  • Maintaining regular integrations calls with our partners to keep their oracle specs up to date
  • Onboarding new partners: analysis of API endpoints, backtesting of oracle parameters through historical data, preparation of deployment files and maintaining a call schedule for implementations
  • Designing the Oracle Integrations Process and documenting it from start to end
  • Work closely together with other members of the Core Tech Team (from engineers to product owners) to manage the relationship with our partners

What skills we need you to have:

  • Solid understanding of APIs, Solidity smart contracts and Oracles
