Job description

Requirements Core Engineering

• 6+ years of professional experience building production web applications
• Strong proficiency in Ruby on Rails and PostgreSQL — comfortable writing migrations, query objects, service objects, and background jobs
• Solid experience with React / Next.js (App Router, Server Components) and TypeScript
• Familiarity with RESTful API design, versioning strategies, and serialization patterns
• Experience with Sidekiq or equivalent background job processing at scale (queue prioritization, retries, cron scheduling)
• Comfortable working with Redis for caching, rate-limiting, and distributed locking

AI-Augmented Development

• Proficient in coding with AI tools — uses LLM-based coding assistants (Claude Code, Copilot, Cursor, or similar) as a daily part of the development workflow, not just for autocomplete but for architecture reasoning, debugging, code review, and test generation
• Comfortable using AI to accelerate unfamiliar territory — e.g., picking up a new library, understanding legacy code, or exploring architectural trade-offs

Product & E-Commerce Domain

• Hands-on experience with order lifecycle management — cart, checkout, payment capture, fulfillment, returns
• Familiarity with payment gateway integrations including tokenization, webhooks, and PCI considerations
• Understanding of shipping & logistics workflows — carrier rate-shopping, label generation, tracking
• Comfort with multi-market / multi-currency platforms — i18n, locale-aware pricing, geo-based routing

Architecture & Infrastructure

• Experience with modular monolith or Rails Engines architecture — isolating bounded contexts within a shared codebase
• Familiarity with Docker, Kubernetes (EKS), and CI/CD pipelines (Buildkite, GitHub Actions)
• Understanding of observability — structured logging, error tracking (Sentry), and APM (New Relic)
• Experience with CDN-backed asset delivery and frontend performance optimization (Core Web Vitals)

Testing & Quality

• Strong testing discipline — RSpec for backend, Playwright or Cypress for E2E, factory-based test data (FactoryBot)
• Familiarity with code quality tooling: Rubocop, ESLint, Prettier, Stylelint

Desired Candidate Profile

• Experience with ML/AI in e-commerce — product classification, recommendation engines
• Familiarity with SWR for client-side data fetching and Material UI component libraries
• Experience with state machines (AASM) for complex entity lifecycles
• Knowledge of cross-border e-commerce logistics
• Familiarity with AWS services — S3, CloudFront, DynamoDB, Lambda
