Golden Horseshoe, Canada Open Systems Technologies Full time
Senior Ruby Developer
We develop and operate a next-generation telemedicine service that lets Canadians
access primary care and other healthcare services through an app. With nearly 2 million
members across Canada, we're reimagining the doctor-patient relationship, leveraging
technology to make Canadian healthcare more accessible, compassionate, and
patient-centered.
As our team of 40+ developers and designers scales to support the growing scope and
complexity of the healthcare services offered, **we're looking for experienced
developers to join our team**.
Our primary backend systems are written in Ruby (we use Grape+Sequel instead of Rails), with
some newer peripheral microservices developed in TypeScript/Node. Although strong Ruby
skills are a requirement for this role, experience or interest in working in TypeScript/Node and
other technologies is a big plus.
As a senior Ruby dev, you will:
1. Work with a focused team of other talented engineers, designers, and product managers to
develop our existing backend systems in a scalable fashion
2. Communicate your design through documentations such as flow charts, sequence, entity
relationship, GraphQL schema or OpenAPI schema diagrams
2. Introduce new ideas, processes, and technologies to help evolve our infrastructure and
architecture
3. Mentor junior developers through collaboration and code reviews
4. Collaborate with the product and business teams to identify new opportunities to develop new
features and products
You should be the kind of person who:
- Cares about high-quality, elegant code and architecture
- Develops in an AGILE way without compromising quality
- Thinks deeply and critically about problems, tools, and processes
- Is passionate about building systems that have a positive social impact
- Has a decent sense humor (our dev team has a weird obsession with the Simpsons,
sandwiches, and questionable emoji)
You should have:
- 3 years working experience developing in Ruby
- 5 years experience building complex, scalable backend systems
- Experience with distributed systems and microservices (Event driven architecture, CQRS,
Domain Driven Design)
- Experience with React or another framework based on unidirectional data flow
- Experience building microservices in Node.js or Deno
- Some experience/knowledge in Typescript
- Experience in designing normalized (3NF) relational SQL databases
- Experience building RESTful and GraphQL APIs at scale
- Experience writing functional tests (unit, integration and system tests)
- Knowledge of best practices such as KISS, YAGNI, DRY and SOLID principles
- Knowledge of OOP and functional paradigms
- A desire to build things for the long-term, with the understanding that the care and attention
you put into your work now will pay off later. #J-18808-Ljbffr
