Senior Software Engineer (L2)

With millions of wallets created and a global audience, Bitcoin.com is one of the world's leading crypto content and onboarding platforms. We're now starting something new, from a blank repo in Rust, and we're early enough that the architecture is still being decided. Join us in bringing crypto to the next billion users. This is a fully remote position based in Europe.

Key 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
  

What We Are Looking For: 

Required 

• 5+ years of professional experience, with a track record of owning systems in production, not just shipping features


• Strong Rust, Go, Java or Kotlin; production Rust strongly preferred


• 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

Why Join Us

• 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, remote-friendly environment
