What to Expect
You’ll be joining our growing Engineering team as a Mid‑Level Backend Engineer, reporting to the Engineering Manager. Our backend team powers critical capabilities like customer decisioning, third‑party service integrations, automation for operational teams, and self‑serve functionality for customers.
You’ll join a culture of high trust and autonomy and no micromanagement, where you’ll have the chance to quickly make an impact on our mission.
Over the next year, you’ll:
- Develop a deep understanding of our core user journeys and backend systems.
- Gain autonomy in delivering medium‑sized projects and play an increasingly important role in driving larger initiatives alongside senior engineers and stakeholders.
- Collaborate cross‑functionally with product managers, designers, and frontend engineers to deliver features that directly impact Raylo’s growth and customer experience.
- Work with a modern backend stack including Ruby on Rails (8.0), Sidekiq Enterprise (200k+ jobs daily), Heroku, GitHub Actions (CI/CD), Playwright (E2E testing), and GraphQL APIs.
What You’ll Do
- Build, maintain, and scale backend services using Ruby on Rails and related technologies.
- Collaborate with product and frontend teams to deliver features that enable new customer experiences and operational efficiencies.
- Participate in code reviews and pairing sessions, sharing knowledge and learning from others.
- Integrate and optimise third‑party services that power our subscription platform.
- Continuously improve backend systems with a focus on scalability, reliability, and performance.
- Take ownership of medium‑sized projects, from design to delivery, and contribute to larger initiatives with senior engineers.
- Write clean, tested, and maintainable code, with CI/CD pipelines in GitHub Actions and end‑to‑end testing in Playwright.
- Work on asynchronous job processing at scale with Sidekiq Enterprise.
You’ll Succeed with
- 2–4 years of backend engineering experience, ideally in a fast‑paced startup or scale‑up environment.
- Strong proficiency in Ruby on Rails and experience with Sidekiq for large‑scale job processing.
- Experience deploying and running applications in Heroku (or similar PaaS), with confidence in CI/CD pipelines.
- Familiarity with GraphQL APIs and automated testing frameworks such as RSpec.
- A collaborative mindset, with strong communication skills and the ability to make progress in ambiguous situations.
- A proactive, curious, and problem‑solving attitude, with a passion for working on real business problems through technology.
- An eagerness to continuously learn and improve your craft, especially within Ruby and Rails.
