Astra is building mission-critical infrastructure for moving money at scale. Our platform processes billions in annual transaction volume with 99.9%+ uptime, powering real-time transfers, bank debits, card disbursements, and complex financial compliance systems. We provide APIs and automation tools that enable businesses to move money programmatically while maintaining strict regulatory requirements.
We're looking for a Backend Engineer to build and ship features across the financial systems that move real money every day. You'll join a small team of experienced engineers working on our distributed microservices architecture, taking on features across payments, fraud detection, compliance, and user management from design through production.
This role is for an engineer who already delivers independently and is ready to take on broader scope. You'll work on larger, cross-domain problems, get real exposure to architecture decisions, and grow quickly in a domain where correctness and reliability matter.
Own features end to end: Design, build, test, and deploy backend features and services across payments, fraud, compliance, and user management, then run and monitor what you ship
Integrate with financial partners and APIs: Build and maintain integrations with banks, card networks, and other third-party services, handling the edge cases that money movement demands
Contribute to design: Write and review technical designs for your own work, participate in architecture discussions, and learn how our domain-driven, event-driven approach fits together
Improve performance and reliability: Find and fix bottlenecks and failure modes across our microservices, and help raise the quality of our tests and observability
Collaborate across teams: Work closely with product and compliance to turn business and regulatory requirements into working software
Required Experience
3+ years of professional software engineering experience building production backend systems
Track record of delivering features independently, from ambiguous requirements to production, with sound judgment on when to ask for help
Solid foundation in algorithms, data structures, and computer science fundamentals
Working experience with distributed systems, event-driven architectures, or microservices
Ability and willingness to travel up to ~15% annually
Education
Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent practical experience. We care more about demonstrated ability than credentials.
Technical Skills
Backend development: Python 3 and web frameworks and APIs (we use Flask)
Databases: Experience with SQL and NoSQL databases
Cloud infrastructure: Google Cloud Platform, or similar cloud platforms
Architecture patterns: Familiarity with domain-driven design, clean architecture, and CQRS is a plus
Preferred Experience
Financial systems: Payment processing, fraud detection, or compliance systems
Financial regulations: Familiarity with AML, KYC, PCI DSS, or similar regulations
Banking integrations: Experience with financial APIs and money movement systems (ACH, card networks)
Third-party integrations: Experience building and maintaining integrations with external services
Scale and reliability: Experience with systems processing high transaction volumes
Direct impact: You'll be a big part of a small engineering team building systems that power a growing fintech platform
Complex problems: Work on sophisticated challenges that few engineers get to solve
Room to grow: A path to broader scope and, over time, technical leadership as the team scales
Financial innovation: Build systems that enable new financial products and services
Competitive compensation with equity in a growing fintech company.
