Senior Software Engineer (Hybrid - Poland)

About the Position

Bitcoin.com, one of the world's leading crypto content and onboarding platforms, is on the lookout for a Senior Software Engineer (Hybrid - Poland) to join our team in Warsaw. We are at the inception of a new project, starting from a blank repository in Rust, and we are in the early stages of defining our architecture. Join us in our mission to bring crypto to the next billion users.

Location: Warsaw (remote for the first few months, then hybrid)

Responsibilities

• Design and build the core services behind the product: APIs, data models, integrations, and make the architectural calls that will shape the system for years.
• Own significant pieces of the product end-to-end, from design through production, including on-call ownership and incident response.
• Partner directly with Product and Design to shape requirements, pushing back where needed so what gets built holds up under real-world load.
• Set the technical standard for the codebase: write code others can maintain, and hold the team to that bar through reviews and mentorship.
• Drive architecture and technical decisions while the foundations are still being laid, and bring the judgment to know which decisions are expensive to reverse.
• Mentor other engineers and help level up the team's practices around testing, instrumentation, and code quality.

Requirements

• 5+ years of professional experience, with a track record of owning systems in production, not just shipping features.
• Strong proficiency in Rust, Go, Java, or Kotlin; production experience in Rust is a must.
• Proven experience designing REST APIs at scale; contracts, versioning strategy, and the judgment to know what will and will not age well.
• Deep experience with AWS or equivalent, containers, and CI/CD, including having built or hardened these systems, not just used them.
• Fluent with AI coding tools like Claude Code, with strong judgment on when to trust, and when to override, their output.
• Experience mentoring engineers and/or leading technical initiatives.
• Clear written and verbal English, and a self-driven work style.
• BS in Computer Science or equivalent experience.

Nice to Have

• Payment rails (SEPA, SWIFT, ACH) or card issuing.
• Regulated fintech: PSD2, KYC/AML, PCI DSS.
• Crypto custody, on-chain settlement, stablecoin flows.
• Monitoring and analytics tools (Sentry, New Relic).
• Experience setting technical direction or architecture for a product from its earliest stages.
• Solid blockchain fundamentals: ERC20, RPC nodes, UTXO vs account models.

We Offer

• Competitive salary and benefits.
• Build a new product from the ground up, not maintain someone else's.
• Room to grow in a fast-moving global organization.
• Shape the architecture and technical culture of a fast-moving global organization.
• One of the most recognized names in crypto.
• Flexible, modern environment.
