Careers — Arthur Ventures
Sr. Software Engineer – API Team at Avalara
Seattle, WA, US

The successful candidate will be a well-rounded software development engineer with strong experience in C# and database design, passionate about developing useful software that will be deployed around the world. 

API team engineers write their own tests and develop their own requirements with assistance from business analysts.  Team members are expected to carefully balance tradeoffs such as usability, security, performance, maintainability, comments, code reviews, automated deployment, and ongoing analysis and improvement.

Avalara’s API team works in an agile/scrum model with low overhead and each employee is expected to self-select their work items in conjunction with their colleagues.  All projects are built using pull requests and each PR must demonstrate that it passes both code review and integration tests before it can be merged.


Job Duties
 

  • Write maintainable, clean code with lots of comments and documentation.
  • Only optimize for performance after the simple approach is tried and performance metrics demonstrate an opportunity for improvement.
  • Be inquisitive and learn about the world of accounting, tax compliance, audits, and business practices whenever the opportunity presents itself.
  • Implement both SQL-based and NoSQL-based data storage solutions in the appropriate contexts
  • Think through your API from the perspective of an attacker and demonstrate every way something could go wrong.
  • Sketch out your own test cases in the planning phase.
  • Write integration tests and unit tests for every pull request.
  • Read and understand requirements, and search out ways to “go big” – to solve the underlying problems.

  • Work with the developer relations team to ensure that each feature is useful for, and simple enough to be understood by, the target audience.
