Job description

Description
Rivalry has been pushing the boundaries on what an esports betting product can be, and we’ve been doing it well. As our user base grows and we enter new global regions, the demand to create new and better products is increasing. We're focused on having the best product in the gambling space. We aren’t willing to accept being marginally better.

We are working hard to create something leaps and bounds above anything else out there. We are investing heavily into our product development team and are looking to hire a Backend Developer to join us on this journey.

Does that sound fun? Keep reading! 

The Role
This is a senior role working alongside the current backend software engineering team; however, you will also work alongside both experienced and junior frontend developers, as well as, various other disciplines in order to share and learn from one another as well as lead projects yourself. 

This role is one part planning tasks and knowledge sharing with the team, one part solo coding work, and one part team resource where people can lean on you for support.

We pride ourselves on keeping up with a modern stack, focusing both on web performance and developer quality of life. We work where we get our best work done. Be it in our Toronto office, remote or a hybrid of both. We're still a team that Pair Programs often, holds regular standups and plays games together regularly. We are a rapidly changing organization and are always open to discuss what we're focusing on and how we're getting there. We expect that you'll be a part of our feature planning, as well as helping vet our implementation options.

You will also be a part of
  • Leading a small team with a singular focus for the sprint, where you can report back to the CTO and Lead
  • Brainstorming sessions where you will contribute ideas to future features
  • Sprint Planning, where you will break down large epics into smaller actionable tasks with details
  • Code Reviews, providing feedback and direction to others
  • Pair Programming over Tuple, providing support to team members
  • Prototyping concepts as a part of idea exploration

Skills, knowledge and expertise
Our challenges involve consuming disparate data sources and transforming the data into usable normalized data sets to be actioned within our application. For instance, we have many sources of data for matches and odds. We need to take these data sources and transform them into a normalized set of matches and data. Each provider has its own scheme for organizing data. Additionally, we are always looking to optimize the real-time notifications of odds to users through web sockets and push notifications. Our core platform has a lot of the same challenges that a forex or stock trading system would have.
On a more technical level, your job will be to architect, develop and maintain our backend application code. Experience with high concurrency systems, load balanced applications, role-based access control systems, geographic and data residency patterns, clean tested code, performance optimization and instrumentation are very important for success in this role. You should have a strong understanding (4 or more years experience) of one or more of the following:
  • Relevant experience as an engineer with a good understanding of backend technologies
  • Proven development background in the following: PHP, NodeJS, Rails
  • Extensive knowledge of some or all of the following: Docker / Containerization, Kubernetes, Security Design, Queuing, Automated testing, Data pipelines
  • You feel comfortable diving into existing code and interacting with developers at all levels of seniority
  • Proven track record of shipping products in an iterative manner 
  • A commitment and drive for quality, technical excellence and result

Our stack is a makeup of
  • Laravel (backend API)
  • NodeJS (microservices and frontend)
  • VueJS (frontend)
  • Websockets (Extensive use of pusher)

Why work here
  • We offer a competitive salary and total rewards package including a comprehensive benefits package and stock options (we believe it's important for everyone on our team to own a piece of the company and share in our success).
  • A chance to work in one of the most exciting and rapidly growing industries.
  • Work with an extremely talented team who share a love for video games and esports on truly innovative projects; we’re not your typical online gambling site -  we’re a tech company first, and a gambling company second.
  • Work where you get your best work done. Whether that’s in an office (when it’s safe enough) or in the comfort of your own home. Our offices are located in Toronto, but a large portion of our company works remotely across 17 different countries.
  • Free video games! Every Rivalry employee gets a monthly stipend.
