Senior Software Engineer, Billing

 Job Description: 

As a Sr. Backend Engineer, you will be a key player in our team, responsible for the design, development, and maintenance of our next-generation Billing service.  

 Responsibilities: 

• Design, construct, test, and maintain a highly scalable, event-driven billing service. 

• Build and operate ingestion pipelines that consume usage events from Pub/Sub and other upstream sources. 

• Implement metering, rating, aggregation, and reconciliation logic that guarantees correctness and idempotency at scale. 

• Ensure systems meet business requirements, regulatory needs, and industry best practices. 

• Collaborate with product managers, architects, engineering leaders, and test engineers to deliver new billing capabilities. 

• Drive improvements on billing reliability, accuracy, performance, and cost efficiency. 

• Troubleshoot and support the platform in production, including on-call rotations. 

 Qualifications: 

• 5+ years of software engineering experience. 

• 3+ years of Java backend development, with hands-on experience using Spring Boot. 

• Degree in Computer Science, IT, or similar field; a Master's is a plus. 

• Strong Computer Science fundamentals in design, data structures, algorithms, problem solving, and complexity analysis. 

• Experience designing and implementing RESTful APIs and event-driven services. 

• Strong understanding of event-driven architectures and asynchronous processing. 

• Experience with messaging systems (Pub/Sub, Kafka, or similar) and at-least-once / exactly-once processing semantics. 

• Hands-on experience with the GCP ecosystem (Pub/Sub, GCS, GKE, Cloud SQL, BigQuery, or similar). 

• Experience architecting, developing, and operating internet-scale, distributed, mission-critical services. 

• Prior experience in developing new features and debugging complex issues with minimal supervision. 

 Nice-to-have: 

• Previous experience building or operating billing, metering, rating, or invoicing systems. 

• Familiarity with file-based data formats such as CSV and Parquet. 

• Experience with stream processing frameworks (Apache Beam/Dataflow, Flink, Spark Streaming). 

• Previous experience in the Contact Center or Telco industry.
