Summary Generated by Built In
Role: Senior Software Engineer - Backend/Search
Team: Commerce - Recommendations & Merchandising
Experience: 3-6 years building production systems at scale
Location: Remote (India)
Employment type: Full-time
We are looking for experienced Senior Software Engineers who can independently own the design, development, and delivery of scalable software solutions with minimal guidance.
We're hiring for two complementary tracks to strengthen different parts of our engineering platform. While both roles require strong software engineering fundamentals and technical leadership, each focuses on a distinct area:
- Track A – Backend & Search Engineering: Build and optimize high-throughput backend services using Go and Python, improve search relevance, and work with large-scale data systems powered by ClickHouse.
- Track B – Data Engineering: Design and maintain robust data pipelines using Airflow and dbt/Dataform, working with BigQuery and ClickHouse to enable reliable, scalable data processing.
In either track, you'll drive technical design decisions, establish engineering best practices, mentor fellow engineers, and help scale our platform while maintaining a high bar for quality, performance, and reliability.
About the Commerce Team
The Commerce (Recommendations & Merchandising) team builds and scales our enterprise-grade e-commerce personalization platform, powering intelligent product recommendations, merchandising, search, and the data infrastructure behind them.
Our platform processes large-scale data and serves high-throughput workloads using modern technologies, including Python, Go, React, TypeScript, and a Google Cloud-based data platform built on Airflow, dbt/Dataform, BigQuery, and ClickHouse.
As part of this team, you'll help design, build, and evolve highly scalable systems that directly impact customer experiences across our platform.
What You'll Do
We're hiring for two complementary Senior Software Engineer tracks. Both roles involve technical ownership, mentoring, and building production-grade systems at scale.

- Optimize warehouse performance, pipeline reliability, and cloud infrastructure costs.
- 3–6 years of experience building and operating production software at scale.
- Strong understanding of software design, distributed systems, and engineering best practices.
- Experience with automated testing, CI/CD pipelines, monitoring, observability, and code reviews.
- Passion for mentoring engineers and driving technical excellence.
Experience with most of the following:
- Go and/or Python
- Search platforms such as Meilisearch, Elasticsearch, OpenSearch, Solr, or Vespa
- Analytical databases such as ClickHouse, BigQuery, or Apache Druid
