About the position

You will work alongside a Senior Rust Developer to lead the implementation of a SaaS platform in Rust. No prior experience with Rust is necessary, only the motivation to learn it.

  • Be directly involved in overseeing the main platform development and lead its implementation.
  • Work across the full product tech life cycle from discovery to delivery. Build internal and external tools to support HeartCore global expansion. Build a web platform and integrate with external APIs.

  • Take features from concept to fully-fledged product.

Requirements

  • Ruby on Rails expertise (3+ years). This is a hard requirement.
  • Available to start working before the end of August 2023 (the sooner the better)
  • Deep experience in building complex modern web applications. We’d expect a developer to typically take 5 years to pick up this level of experience.

  • Good knowledge of security best practices.
