Senior Backend Developer

At Vayu, your code will directly power how companies generate revenue from their product usage. You’ll design backend systems that process real-time events, pricing logic, and financial data at scale.

We’re building a modern revenue infrastructure platform for B2B companies. While traditional pricing models (flat-rate subscriptions or per-license billing) were once sufficient, today’s leading companies require more dynamic models, based on consumption, usage provisioning, service tiers, or even customer satisfaction, and that creates serious technical complexity.

Vayu integrates easily into modern applications, transforming complex billing into predictable, scalable revenue management.

We’re growing fast, backed by strong funding and real customer demand, and we’re looking for a senior engineer to help us scale smart.

Your Mission At Vayu

• End-to-end ownership: You will build features from concept to launch, from designing backend architecture and managing infrastructure, through writing tests and automations, to extending capabilities in our developer-facing APIs and SDKs.
• High-impact challenges: Design and maintain scalable real-time event metering, complex billing logic, and integrations- all while ensuring data integrity and multi-language SDK support.
• Modern tech stack: You will leverage serverless architectures, real-time streaming, SQL and NoSQL databases, and large-scale batch processing to build scalable, reliable systems.
• Teamwork that drives results: You will collaborate closely with developers, QA, designers, and even customers to stay aligned and deliver impactful solutions together.
• Career growth opportunities: A rare opportunity to expand your tech skills, build from scratch, take on new challenges, and lead technically.
  
  

• System-level thinking: You understand how complex, event-driven systems work end to end, can follow how data flows, identify edge cases, and design for performance and scalability.
• 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 ownership mindset: You take full responsibility for the systems you build, with a deep focus on quality, performance, and long-term maintainability.‍
• Great communication skills: You explain complex ideas in a clear and structured way, engage in thoughtful technical discussions, and help align engineers, product, and stakeholders around smart decisions.
