Job Requirements
- Strong proficiency in at least one of: Python, TypeScript/JavaScript, Go
- Experience designing and building test frameworks from scratch (not just adding tests to an existing suite)
- Deep familiarity with API testing — REST, webhooks, idempotency, retry behavior, edge cases at integration boundaries
- Working knowledge of databases (SQL) and the ability to write test data seeding/cleanup logic correctly
- Experience testing payment flows, ledger systems, or compliance pipelines (strong preference, will train for the right engineer)
- Understanding of idempotency, double-spend prevention, and eventual consistency in distributed systems
- Familiarity with webhook-based event systems and out-of-order delivery scenarios
- Experience integrating test suites into CI pipelines (GitHub Actions, GitLab CI, or similar)
- Ability to instrument tests for flakiness detection, coverage tracking, and runtime performance
- Comfort operating in a cloud environment (AWS, GCP) and reading service logs/traces
- You can define what "this test passing" actually means in production terms
- You've contributed to or owned an incident post-mortem with concrete prevention steps
- You understand canary deployments, feature flags, and how to write tests that survive staged rollouts.
Benefits
- Work on infrastructure that handles real money for millions of users
- A team that treats quality as a first-class engineering problem, not a compliance checkbox
- Remote-friendly with a distributed, high-ownership engineering culture.
