Senior Software Engineer – Backend

Here's the tl;dr:

This is Rise

We set out to build a company that helps teams make the most of their time. Why? Because time is the most valuable asset we can spend only once. Becoming more aware of the fact that we have limited time is one of our key beliefs. And, not coincidentally, the central point in Rick’s bestselling book, launching internationally in February 2022.

The Rise backend powers our front-end and apps on one side, and integrates with downstream calendar providers like Google Calendar on the other. Additionally we've built a scheduling engine that can instantly rank and score timeslots for our Find a Time feature. The initial backend is built with a Heroku/Ruby/PostgreSQL/Redis/Sidekiq stack. We are looking for a senior backend engineer to help launch and scale the Rise product.

What you'll be working on 💻

As an early engineer you'll work on many different aspects of the product. A few examples:

  • Collaborate with our client and mobile teams to define a scalable and extensible API
  • Dive deep into our event scheduling engine to improve performance or extend the capabilities
  • Optimize our development workflow (for example making the first-time local setup for new hires easier, to setting up a staging environment, improve our build pipeline)
  • Evaluate and utilize new libraries, frameworks and and tooling
  • Involvement in hiring and onboarding of new engineers

What our ideal candidate looks like 💅

  • Significant experience in building distributed, scalable, performant and asynchronous backend applications in the cloud (AWS, GCP, etc)
  • Significant experience with at least one scripting language, preferably Ruby 💎
  • Cares a lot about high quality, readable, structured object oriented code. Advocates best practices and architecture patterns. Is able to make trade-offs between extensibility, optimization and execution speed. Empowers others by reviewing code.
  • Proficient with different types of testing (integration, unit, stress, etc)
  • Experience with system observability: automates eyes and ears throughout the stack with tooling (Grafana, New Relic, Sentry, etc). Familiarity with incident handling is a plus.
  • Has a habit of being paranoid about security and privacy (input validation, network encryption, authentication, authorization)
  • Is autonomous, able to independently pick up tasks and full projects and work through them end-to-end
  • Is product and user minded: is always focused on how their work will impact or optimize the experience of Rise users

We realize that as a founding team we're from similar backgrounds, that we have unconscious biasses and that we have work to do here. This is why we explicitly want to invite and encourage people from underrepresented groups to apply.
