Job Description

Senior Full-Stack Software Developer

🔥 Since our Series A last year, we've become one of the fastest-growing startups to hit Series-B metrics, and now we're hiring for a Senior Full-Stack Software Developer to join our team to work on building the foundations of our products and vision.

We're looking for talented and motivated developers with 4+ years of experience. Our developers own products from end-to-end. If you're interested in building elegant software with far-reaching effects in our modern healthcare landscape, join us!

What You'll Do

  • Design initial feature specifications.
  • Build robust backend APIs.
  • Write intuitive frontend code.
  • Oversee ongoing improvements for launched products.
  • Drive projects from concept to completion in an environment of autonomy and creativity.
  • Shape not just our product, but our culture: who you work with, and how we all work together.
  • Make foundational technical decisions critical to the company's success.
  • Work incredibly closely with co-founders, investors, and customers to deeply understand problems and build the best product.

Our current stack includes: React, React Native, Typescript, and Firebase.

How We Work

  • We're a hybrid team with members across Canada and the US.
  • Our main tools of collaboration are Slack, Notion, Figma, Google Meets, and email.
  • We foster an environment where you can learn the inner workings of a growing startup.
  • You'll contribute during investor meetings and demonstrate your features to potential customers.
  • We genuinely expect you to take advantage of this learning opportunity of a lifetime, even to potentially start your own venture in the future.

About You

We're looking for a product-minded developer who:

  • Actively engages with the 'why' behind what they're building.
  • Has a thirst for using technologies to leapfrog human problems.
  • Has a strong track record of bringing products to life.
  • Has experience in a backend framework (like Node ).
  • Is proficient with the staples of full-stack web development: HTML, JavaScript, and CSS.
  • Understands the balance between moving fast and building for the long haul in an early-stage startup.
  • Can minimize scope, prioritize ruthlessly, and implement rigorously.
  • Takes ownership and sees things through to completion.
  • Can take a stand yet commit even when they disagree.
  • Doesn't need heavy direction and enjoys the 'grey' areas.
  • Likes open-ended problems and thrives in the face of uncertainty – the elements of a startup environment.

Our Interview Process

Our interview process is designed to be thorough and respectful of your time:

  • Take-Home Assignment: A practical exercise to assess your coding skills.
  • Technical Interview: A deeper dive into your technical expertise and problem-solving.
  • Team Interview: An opportunity to meet potential teammates and discuss collaboration.
