Senior Backend Engineer (Node.js)

We are looking for a highly skilled Backend Engineer to help design and scale the core services powering our platform.
You will work on business-critical backend services, contribute to architectural decisions, and help solve complex scalability, performance, and reliability challenges.

What you'll do:
Design backend services capable of handling growing traffic and increasing product complexity
Build APIs and internal platform components that become the foundation for future development
Improve system reliability, observability, and operational efficiency
Analyze bottlenecks and optimize performance across services and databases
Solve production issues and prevent them from recurring through better architecture and engineering practices
Drive technical discussions and influence long-term engineering decisions
Partner with product and engineering stakeholders to deliver solutions that balance speed and quality

You are likely a strong fit if:
You have spent years building and operating backend systems in production
Node.js and TypeScript are technologies you know deeply rather than tools you've only used occasionally
You understand trade-offs in system design and can justify architectural decisions
You are comfortable owning services end-to-end, from implementation to monitoring and incident response
You have practical experience with AWS and modern cloud-native development
You have worked with document databases, caching layers, and asynchronous processing patterns
You can quickly isolate problems in complex systems and drive them to resolution

Preferred Qualifications

Experience with event-driven architectures and asynchronous processing
Hands-on knowledge of messaging systems and distributed workflows
Experience building systems in fintech, trading, marketplaces, or other high-load environments
