Overview

Description

As a Rails Engineer for our product “Spacely,” you will take the lead in developing and operating our web service, as well as implementing new features.

You will be primarily responsible for developing functions used by clients in the real estate industry, such as 360-degree content management, property data management, access analytics, and marketing tools tailored to real estate businesses. By bringing technology to an industry where analog practices still dominate, particularly in the essential area of housing, you will have the opportunity to contribute to driving digital transformation (DX).

This role offers the chance to work on the core development of our product, including not only the foundational features that support the entire Spacely platform but also external APIs and large-scale batch data processing. You will be involved in the development process from the planning phase through to implementation—not just handling one part of the product. Working closely with our research team, you’ll have the chance to turn experiments and academic insights into meaningful value for users.

Our team fosters a culture that embraces new technologies, with adoption driven by those who propose them. We actively incorporate innovative approaches and are open to bold technical decisions, encouraging engineers to take initiative and explore new possibilities.

Responsibilities

  • Web development using Ruby on Rails
  • Development of bi-directional APIs for integration with external systems
  • Documentation creation (e.g., external API specifications, internal design documents)

Required Skills

  • Experience in web development using Ruby on Rails (3+ years preferred)
  • Front-end development experience (JavaScript/HTML/CSS)
  • Experience with RDBMS (MySQL or PostgreSQL)
  • Experience writing test code using RSpec
  • Knowledge of AWS

Preferred Skills

  • Development experience with Vue.js or React.js
  • Knowledge of MySQL tuning and query optimization
  • Understanding of search engines (e.g., ElasticSearch or Algolia)
  • Experience writing API documentation using OpenAPI
  • Experience with Agile or Scrum development methodologies
  • Experience developing APIs for mobile applications
  • Experience in designing architecture and launching and operating services
  • Experience managing development teams of several members
