We're looking for a Senior Software Engineer to help build the core infrastructure powering global payments. You'll design and implement systems that process billions of dollars in transactions, working across our payment orchestration layer, merchant APIs, and real-time settlement engine.
This is a high-impact role where your code ships to production quickly and handles real money from day one. You'll collaborate closely with Product to shape what we build, with fellow engineers on how we build it, and have significant ownership over the systems you create.
Design and implement payment processing systems that handle high throughput and strict reliability requirements
Build APIs and SDKs that merchants use to integrate Coinflow into their platforms
Develop fraud detection and risk management features using real-time data analysis
Architect systems for performance, reliability, and observability at scale
Optimize database queries, caching strategies, and service communication patterns
Instrument services for monitoring, alerting, and debugging production issues
Work end-to-end on features from technical design through deployment and iteration
Collaborate with Product and Design to translate requirements into elegant technical solutions
Balance speed of delivery with code quality and long-term maintainability
Contribute to technical decisions around architecture, tooling, and best practices
Mentor other engineers through code review, pairing, and knowledge sharing
Help shape engineering culture as the team grows
5+ years of professional software engineering experience
Strong proficiency in TypeScript and Node.js; experience with React is a plus
Deep understanding of REST API design, relational and document databases (especially MongoDB), and distributed systems concepts
Experience building systems that handle high transaction volumes or strict correctness requirements
Comfortable with cloud infrastructure (AWS, GCP, or similar) and containerized deployments
Track record of shipping and maintaining production systems
Clear communicator who can discuss technical tradeoffs with engineers and non-engineers alike
Bonus: Experience in payments, fintech, or blockchain/crypto
