• Ship fast, iterate, communicate blockers

Requirements

• 4+ years of production Python experience (FastAPI or similar async frameworks)
• Strong SQLAlchemy / PostgreSQL skills (complex queries, ORM patterns, performance)
• Experience integrating third-party APIs (payment, e-commerce, webhooks)
• Mandatory: daily working experience with Claude Code, Cursor, or similar AI coding tools
• Mandatory: demonstrated ability to leverage AI effectively - prompt engineering, reviewing AI output, steering implementations toward production quality
• Comfortable with AWS (ECS, RDS, S3, Secrets Manager - or equivalent cloud)
• Strong debugging skills - catch and correct AI-generated mistakes
• Ability to quickly understand unfamiliar codebases and spot issues
• Self-driven, proactive, no hand-holding needed
• English: working proficiency (async team communication)

Nice to Have

• Experience with Shopify API or Stripe integration
• Familiarity with Terraform and infrastructure-as-code
• Docker and container orchestration (ECS Fargate)
