Senior Backend-Oriented Full Stack Developer

About the Role:

End-to-end ownership: You’ll work across the stack on each task: from backend architecture and infrastructure, through tests and automations, to extending capabilities in our developer-facing APIs and SDKs. We build features start to finish.

Tough and varied problems: You’ll deal with real-time event metering at scale, complex business logic powering our billing engine, integrating with third-party systems while managing valid entity state, and making features accessible across multiple language SDKs.

Modern tech stack: Our stack includes serverless architecture, real-time streaming platforms, both SQL and NoSQL databases, and large-scale batch processing.

Meaningful impact: You’ll be building critical systems. The work is fast-paced and trusted — billing has no room for mistakes. We move quickly, but balance it with stability, because in billing, every detail matters.

Teamwork that delivers: You’ll work closely with developers, QA, designers, and sometimes even customers. We collaborate directly, stay aligned, and get things done together.

Requirements:

• 5+ years of hands-on experience in software development, with a strong backend focus
• Fluency in TypeScript or Python – deep understanding of language features, ecosystem, and best practices
• Solid understanding of databases – SQL or NoSQL, knowing how to model, query, and optimize effectively
• Experience building APIs that are clean, consistent, and used by other developers (bonus for SDK design)
• Strong sense of ownership – you take responsibility for what you build and care about quality, performance, and maintainability
• Good communication skills – you can explain your thinking, ask the right questions, and work well with teammates and stakeholders

Nice to Have:

• Comfortable jumping into frontend code when needed
• Experience working with serverless platforms or event-driven systems
• Prior exposure to developer tooling, SDKs, or billing/finance systems
• Familiarity with batch processing frameworks like PySpark
• Contributions to open source or internal tooling that improved team velocity
