About Us

We’re a venture-backed fintech startup on a mission to make crypto safer and more compliant. Our platform helps digital asset businesses navigate evolving regulatory landscapes through intelligent screening, monitoring, and reporting tools. We believe in building systems that are scalable, secure, and developer-first.

We’re looking for a Senior Software Engineer to join our core engineering team and help design, build, and scale the infrastructure that powers our crypto compliance platform.

What You’ll Do

  • Build and scale Python-based microservices and REST APIs that power compliance workflows (e.g., sanctions screening, transaction monitoring)
  • Architect and maintain highly available, secure backend systems in the cloud (AWS/GCP)
  • Design and manage data pipelines and databases to ingest and analyze real-time and batch crypto transaction data.
  • Implement robust DevOps practices for continuous delivery, observability, and infrastructure-as-code.
  • Ensure compliance-grade security, logging, and auditability of backend systems.
  • Collaborate with product, data, and compliance teams to translate regulatory requirements into technical features
  • Mentor junior developers and contribute to architectural decisions and best practices.

What You Bring

  • 5+ years of backend engineering experience, with a strong focus on Python
  • Proven experience designing, scaling, and maintaining microservices and RESTful APIs
  • Strong understanding of relational (PostgreSQL) and NoSQL databases
  • Solid experience with cloud infrastructure (AWS preferred) and infrastructure-as-code tools (Terraform, CloudFormation)
  • Hands-on experience with Docker, Kubernetes, and CI/CD pipelines
  • Familiarity with secure development practices, API authentication (OAuth2, JWT), and compliance-oriented logging/auditing
  • Excellent communication skills and a startup mindset — you're proactive, adaptable, and ready to take ownership

Bonus Points For

  • Fintech or crypto industry experience
  • Knowledge of blockchain analytics, chain forensics, or crypto compliance tools
  • Familiarity with screening APIs (e.g., ComplyAdvantage, Chainalysis, Elliptic)
  • Experience with event-driven systems (Kafka, Pub/Sub)
  • Previous startup experience or greenfield system design

Why Join Us?

  • Early-stage opportunity with real impact and ownership
  • Mission-driven team solving one of crypto’s biggest challenges
  • Competitive compensation, equity, and flexible work environment
  • Work with smart, passionate people at the intersection of fintech, crypto, and regtech
