What you’ll do

As a Senior Ruby on Rails Engineer/Developer, you will be responsible for designing, building, deploying and maintaining a large client-facing web application and its API used to configure and provide analytics of a high-volume real-time bidding platform. As a result, there will be opportunities to contribute to open-source, review code, and share knowledge.

You will be working with experienced, passionate programmers as part of the application team within a broader engineering organization with a strong technical culture. We value a broad knowledge base and encourage our employees to develop a well-rounded skill set and be comfortable contributing to any part of the codebase.

We work in agile scrum teams, which means you will be working closely with a smaller group of co-workers. We use daily stand-ups and put a strong emphasis on communication and knowledge-sharing. Within a Scrum team, although members may have more specialized areas of expertise, each person will contribute to all types of tasks - client-side code, server-side code, and some manual QA. A variety of community-of-practice groups are also active for conversation around specific topics.

You enjoy building things. You value craftsmanship in software. You enjoy reading code, and you're probably in the habit of reading the source for your dependencies. You are using your acquired experience and maturity to challenge positively the status quo to aspire for higher code quality and development efficiency while understanding the business needs. You are a good communicator who appreciates learning from and teaching others.

In this position, the chosen candidate is expected to have a hands-on, problem-solving approach and a friendly human-facing side to communicate and manage expectations.

Our tech stack includes a Ruby on Rails GraphQL API with PostgreSQL, and a Typescript and React.js UI with Webpack.

Other things you probably enjoy or would be interested in learning:

  • Working with the Rails and Javascript ecosystems
  • Working with modern browser technologies and paradigms
  • Working on server-side code
  • Building performant, secure and accessible web applications
  • Building innovative products and features integrated with existing systems
  • Maintaining large and continuously evolving web apps
  • Translating complex business requirements into maintainable code

What you need to succeed in this role:

  • Minimum 5 years’ experience building Ruby on Rails applications with PostgreSQL 
  • Interest in building and interacting with single-page applications (React, Typescript a plus)
  • Solid experience building, testing and maintaining HTTP APIs (GraphQL APIs a plus)
  • Experience working in a team with a willingness to work in an agile multi-team environment
  • Strong database skills (regarding integrity, design, performance, etc)
  • Ability to participate in the design, implementation, and testing of the API and UI
  • Participate in code reviews and spread your expertise to the team
  • Capacity to accept constructive code review and challenge your beliefs when presented with relevant evidence
  • Strong problem-solving skills with a can-do attitude
  • Interest and experience mentoring more junior team members
  • Excellent English communication skills – verbal, written and spoken; French is an asset
