Fullstack разработчик

EPAM builds and scales a multi-tenant SaaS platform serving real estate and asset-management data at scale.

• Design and implement features across a Ruby on Rails 8 monolith using established patterns: form objects, query objects, service objects, Pundit policies, and ViewComponents;
• Build dynamic, server-rendered UI with Hotwire (Turbo + Stimulus) and Bootstrap 5, and richer interactive interfaces with React + TypeScript (MUI, ag-grid, react-select, chart.js) bundled via Vite;
• Model and optimize data in PostgreSQL, write efficient queries, design indexes, eliminate N+1s, and author safe, zero-downtime migrations;
• Implement asynchronous and scheduled work with Sidekiq for data ingestion pipelines, file processing, and long-running jobs;
• Write comprehensive automated tests (RSpec request/system specs, Vitest) as a standard part of every change;
• Ship code through a CI/CD pipeline that builds Docker images, pushes to AWS ECR, and deploys to Kubernetes clusters across staging and production;
• Collaborate on infrastructure managed via Terraform and Kubernetes manifests housed in dedicated infrastructure repositories.

• 5+ Years of professional software development experience;
• 3+ Years building production applications with Ruby on Rails, including a working grasp of Rails conventions, ActiveRecord, and background processing with Sidekiq;
• Proficiency in PostgreSQL, writing efficient queries and reasoning about indexes and schema changes;
• Expertise in React and TypeScript, and flexibility to use a server-rendered Hotwire (Turbo/Stimulus) environment;
• Familiarity with authentication and authorization patterns (e.g. Auth0, OmniAuth, Warden, Pundit, or comparable tools);
• A test-first mindset, writing meaningful tests and verifying behavior rather than assuming it;
• English proficiency at B2 level or higher;
• Nice to have: Deeper PostgreSQL expertise in query tuning, indexing strategy, connection pooling, and safe zero-downtime migrations, Knowledge of AWS services (ECR, S3, RDS) and deploying containerized applications to Kubernetes, Experience with Terraform and infrastructure-as-code workflows, especially where app and infra live in separate repositories, Familiarity with multi-tenant architectures (subdomain-based tenancy), Exposure to data-pipeline / ETL work, file ingestion (S3 multipart, SFTP), and document/spreadsheet processing, Experience with observability tooling (Sentry, New Relic, Prometheus) and production hardening (rate limiting, secure headers, health checks).
