We are looking for a strong Backend Python Tech Lead to build and run the backend of our crypto-banking product. This is a hands-on role: you will own key technical decisions, set engineering practices, and help the team deliver safely and fast.

What you will do

- Design, build, and maintain backend services using Python, Django, PostgreSQL.

- Work deeply with Django ORM: schema design, migrations, query optimization, data integrity, and performance.

- Integrate and operate Fireblocks for secure digital asset operations (wallets, transactions, approvals, policies).

- Integrate with external services (KYC/KYT, Travel Rule, banking/FX partners, internal services).

- Build secure and auditable flows: balances, transfers, limits, status tracking, idempotency.

- Improve reliability: background jobs, retries, rate limits, error handling, observability.

- Ensure security and compliance-by-design: permissions, audit trails, secure secrets handling.

- Mentor engineers, drive code reviews, testing, and release discipline.

- Work closely with Product/Compliance to turn requirements into clear technical solutions.

What we expect

- Strong production experience with Python + Django.

- Strong PostgreSQL skills (indexes, transactions, query plans, locking basics).

- Excellent ORM skills (efficient queries, avoiding N+1, correct relations, safe migrations).

- Solid experience with API integrations (timeouts, retries, idempotency, webhooks).

- Engineering leadership: architecture ownership, good trade-offs, delivery focus.

- Security mindset and good coding practices.

- Fluent English and Russian

Nice to have

- Experience with CI/CD pipelines and release workflows.

- Docker and practical infrastructure basics (environments, secrets, monitoring/alerts).

- Experience with Fireblocks in production.

- Fintech / crypto / payments background.

What success looks like

- Backend architecture is clear, maintainable, and scalable.

- Fireblocks and other integrations are stable, observable, and safe.

- The team ships with predictable quality: reviews, tests, clean releases.

- Product and compliance needs are translated into simple, secure backend solutions.
