Onix-Systems — вакансії

We are looking for a highly skilled Senior Ruby on Rails Developer to join our dynamic team. You will be responsible for designing, developing, and maintaining robust, scalable, and high-performance web applications. The ideal candidate has deep experience with Ruby on Rails, a strong understanding of relational databases, and expertise in building transactional business applications and RESTful APIs.
The target application has been in development for 2-3 years, meaning you will be working with an existing codebase. The application serves as a backend API for a React frontend, so experience with such an architecture is required. While knowledge of React is a plus, it is not mandatory.

Key Responsibilities:

• Design, develop, and maintain Ruby on Rails applications with a focus on performance and scalability.
• Write clean, efficient, and well-tested code using RSpec and observe style requirements dictated by Rubocop.
• Architect and optimize PostgreSQL databases, ensuring efficient queries and schema design.
• Design and implement RESTful APIs using Grape and other frameworks.
• Develop and manage asynchronous background jobs using Sidekiq or similar task managers.
• Work with Redis for caching and job queue management.
• Deploy and maintain applications in Linux/Docker/Kubernetes environments.
• Use AI assistive technologies (e.g., GitHub Copilot, Cursor) to improve development workflows and efficiency.
• Maintain and enhance an existing codebase, ensuring adherence to Clean Architecture or related modern design patterns.
• Collaborate closely with frontend teams building React applications to ensure seamless integration between backend APIs and frontend components.
• Maintain a disciplined approach to task management, ensuring timely delivery and high code quality.
• Communicate effectively in English with team members, stakeholders, and clients.

Requirements:

• Extensive experience with Ruby and Ruby on Rails
• Solid experience with RSpec for testing and adherence to style guides like Rubocop
• Strong SQL knowledge with PostgreSQL and experience with Redis
• Experience in developing transactional business applications and designing scalable database schemas
• Proven expertise in REST API design, particularly with Grape
• Experience with Sidekiq or other asynchronous job processing frameworks
• Excellent knowledge of Linux and Docker; basic familiarity with Kubernetes
• Strong task management skills and ability to work independently
• Familiarity with AI-assisted development tools (e.g., GitHub Copilot, Cursor, or similar)
• Fluent English communication skills (spoken and written) are crucial
• Experience working on an existing codebase for long-term projects (2-3 years)
• Experience with backend API development for React frontends
• Understanding of modern design patterns, particularly Clean Architecture or similar.
