Senior Backend Engineer: Attribute Enrichment (Remote)

About the role

This role focuses on developing new backend services that deliver machine learning-generated enriched attributes to customers, along with a high-throughput, low-latency Badges service. The work involves designing these systems for heavy traffic, ensuring they are highly available, and implementing continuous integration and deployment pipelines. A key part of the job is managing enriched items, their metadata, and derived attributes within a dedicated database, focusing on data consistency, performance, and availability for other services and APIs.

The Senior Backend Engineer will be responsible for setting up observability, monitoring metrics, and alerting for the services they build, utilizing tools like Prometheus, Grafana, PagerDuty, and AWS CloudWatch. This includes writing and maintaining unit, integration, and end-to-end tests to ensure the reliability and quality of the backend services. The position requires a strong computer science background and familiarity with networking principles to contribute effectively to the platform's architecture.

Success in this position means delivering robust, scalable, and well-tested backend solutions that enhance Constructor's e-commerce search and discovery platform. It involves collaborating with cross-functional teams to integrate new features and ensuring that the attribute enrichment and badges products drive meaningful revenue and conversion gains for leading global e-commerce brands. The ideal candidate will demonstrate proficiency in Python and experience with designing and maintaining high-load real-time services and public APIs.

The base salary for this role ranges from $115,000 to $195,500 USD, with stock options offered in addition.
