India

We are seeking a highly skilled Senior Backend Engineer with strong expertise in ASP.NET and a proven track record in building scalable, data-intensive systems. The ideal candidate is a back-end generalist who thrives at the intersection of API design, distributed systems, and data engineering. This role requires hands-on experience with API gateways, event-driven architectures, pub-sub systems, and large-scale data pipelines, making it well-suited for someone who is passionate about solving complex backend and data challenges.
Key Responsibilities

  • Backend Development: Design, develop, and maintain robust backend services and APIs using ASP.NET.

  • Database Management: Work with relational and NoSQL databases (MongoDB, DynamoDB) for high-performance data storage and retrieval.
  • Scalability & Performance: Architect systems that scale for high throughput and reliability across distributed environments.
  • Collaboration: Partner with frontend engineers, data scientists, and DevOps teams to deliver end-to-end solutions.
  • Best Practices: Champion clean code, test-driven development, CI/CD, observability, and performance optimization.

  • 5–8 years of experience in backend development, with a strong focus on ASP.NET/ .NET Core.
  • Deep understanding of API design principles, REST/GraphQL standards, and API gateway management.
  • Proven experience with event-driven systems (pub-sub, message queues, event scaling).
  • Hands-on expertise with Apache Kafka, Apache Spark, or similar streaming technologies.
  • Strong background in ETL pipeline development and working with large datasets.
  • Experience with NoSQL databases such as MongoDB and DynamoDB.
  • Solid understanding of cloud-native architectures (AWS, Azure, or GCP).
  • Strong problem-solving skills with the ability to design scalable and fault-tolerant systems.

Preferred Qualifications

  • Exposure to data platforms (e.g., Snowflake, Redshift, BigQuery).
  • Experience with containerization (Docker, Kubernetes) and microservices.
  • Knowledge of monitoring, observability, and logging tools (e.g., Prometheus, Grafana, ELK stack).
