• Solid architecture: clear boundaries, backward-compatible changes, versioned contracts.
• Testing discipline (pytest, factories/fixtures, contract tests) and operability mindset (metrics/alerts).
• Security basics (PII handling, secrets, OWASP); fintech/SOC2/PCI awareness is a plus.
• Clear English communication and effective AI-assisted development habits.

Nice to have

• Experience with third-party APIs and a lightweight integrations framework (auth, retries, idempotency, webhooks).
• Fintech/payments/KYC/KYB exposure.

How we work

• Remote-first across Eastern Europe with reasonable overlap to Pacific Time.
• Product-driven, metrics-led delivery; ship with flags, measure, iterate.
