Calgary, Alberta, Canada atVenu Full time

Reports To: Development Manager/Principal Engineer 

About the Job:

We're looking for a Senior Software Developer (API) to join our growing team at atVenu. This newly created role reflects our continued expansion and focus on scalable, high-quality API design.

As a key technical contributor, you'll collaborate closely with Product Managers and development teams to design, build, and maintain robust APIs ranging from inventory control to payment transaction feeds for our enterprise customers as well as our scrappier startup users. You'll be a hands-on leader—skilled in balancing trade-offs, solving complex problems, and driving cross-team solutions. Your expertise will help shape our technical direction while mentoring other developers and championing engineering excellence.

You Will:

  • Collaborate with Product Managers and cross-functional teams to understand business needs and translate them into pragmatic, performant technical solutions. 
  • Deliver high-value projects with no direct supervision; engaging senior staff members to validate new ideas, test assumptions and provide mentorship. 
  • Design, develop, and maintain scalable and compliant APIs that can support our platform within Canada, the United States, Europe and counting.
  • Implement and enforce API security best practices, including authentication, authorization, rate limiting, data validation, and protection against common vulnerabilities (e.g., injection attacks, CSRF, and data leakage).
  • Architect services and systems using accepted design patterns that allow for iterative, autonomous development and future scaling
  • Proactively identify technical debt before it turns into a long-term problem while balancing the effort/reward of corrective action; will encourage team to do the same.
  • Anticipate future use cases and make design decisions that minimize the cost of future changes.
  • Act as the project manager for long projects and/or complex groups of user stories, inclusive of scope, schedule budget; will ensure milestones are reasonable to support agile practices.
  • Sit on architecture review boards; will expand beyond API dev projects.
  • Provide mentorship to more junior developers.

You Should Have:

  • At least 8 years progressive experience as a software developer, with at least 2 years of specialization in publishing and maintaining public APIs.
  • Be considered an API dev subject matter expert; you will be our internal north star when it comes to API development. 
  • Experience in the fintech industry, with heightened awareness around security, geography and overall API best practices. 
  • Be highly adaptable, with proven ability to learn/use various programming languages; preferably with hands on Ruby on Rails, GraphQL, AWS experience. 
  • Proven ability to trouble-shoot complex technical problems and participate in code/architecture reviews.
  • Excellent team player: able to work across teams, acting as a leader when required and managing conflict independently, with the knack of leaving everyone involved feeling heard and respected.
  • A genuine interest in the live event space, you know how to work hard and play hard.
