Experienced Developer

Role: Deliver well-scoped features and bug fixes across the backend platform with minimal supervision and grow toward owning whole subsystems.

Responsibilities:

• Implement features within existing modules following the codebase's patterns: keep controllers thin, push business logic into service objects/interactors, and use models for persistence and invariants.
• Build new GraphQL types/mutations or REST endpoints; write request specs and keep API documentation current.
• Add Sidekiq workers and scheduled jobs following established patterns for retries, error reporting, and idempotency.
• Write Rails migrations safely, with awareness of locking and zero-downtime deployment constraints.
• Implement third-party integrations under guidance, with proper retries, error handling, and webhook ingestion.
• Solid practical experience developing React features/components using hooks, routing, API integration, and modern tooling; capable of independently implementing requirements, debugging issues, and following established frontend architecture and best practices.
• Add and maintain authorization policies, feature flags, and audit trails where appropriate.
• Write comprehensive RSpec unit, request, and integration tests; keep code coverage healthy.
• Run linting, static analysis, and dependency audits locally before opening a PR; resolve issues you introduce.
• Debug failing CI runs in GitHub Actions and address regressions promptly.
• Update Docker / Docker Compose configurations for local dev when new services are added.
• Participate in PR reviews and give constructive feedback to peers.

Skills Required:

• 3-5 years of working experience.
• Solid Ruby on Rails (2+ years), comfortable with Active Record associations, scopes, validations, and callbacks.
• PostgreSQL: writing safe migrations, basic indexing, joins, and reading EXPLAIN output.
• RSpec, FactoryBot, and stubbing external services in tests.
• Git, GitHub PR workflow, and basic GitHub Actions troubleshooting.
• Docker basics: building images, running containers, and using Docker Compose locally.
• Familiarity with at least one of: Sidekiq, Redis, Memcached, OpenSearch/Elasticsearch.
• REST API design fundamentals; some exposure to GraphQL.
• AWS basics: reading logs in CloudWatch, locating a task in ECS, and retrieving a secret from Secrets Manager.

Preferred

• Templating engines (Slim/ERB) and form helpers.
• Payment-flow experience.
• TypeScript at a level sufficient to read AWS CDK stacks.
• Basic performance debugging tools.
