Ruby

We are looking for a Senior Full-Stack Ruby Software Engineer to build and scale a multi-tenant SaaS platform serving real estate / asset-management data at scale. You'll work across the entire stack — from PostgreSQL query optimization and background data pipelines to server-rendered Hotwire views and interactive React + TypeScript front-end components — and own features end-to-end, from spec through production deployment on AWS-backed Kubernetes. This is a hands-on engineering role on a team that values high test coverage, clean conventions, and shipping reliable software to a demanding production environment.

Чим ви будете займатися у цій ролі

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

Навички

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

Буде перевагою

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)
