Software Engineer II

Our Opportunity
Chewy is seeking a full-stack Software Engineer to join our Site Analytics Engineering team. In this role, you will design, build, and maintain the applications and services powering Chewy's web and app analytics and experimentation platforms. You'll collaborate closely with storefront engineers and cross-functional stakeholders to ensure seamless integration and high performance across web and mobile platforms.
The Site Analytics Engineering team is responsible for data analytics and experimentation infrastructure - we empower our stakeholders with high quality data services, behavioral (Clickstream) event tracking, and experimentation (A/B testing) platform capabilities. As a Senior Engineer, you will help define the technical direction of our event-driven analytics platform and lead the development of scalable, reliable backend systems that enable actionable insights and measurable business impact.
What You'll Do

• Design, build, and maintain scalable backend systems, APIs, and microservices that power Chewy's internal clickstream analytics, experimentation, and data platforms.
• Develop and operate event-driven architectures using Apache Kafka to support real-time data collection, streaming, and integration, ensuring data accuracy and consistency across analytics pipelines.
• Architect and manage cloud infrastructure on AWS in partnership with DevOps, with a focus on scalability, high availability, fault tolerance, and disaster recovery.
• Implement robust, fault-tolerant data services that ingest, process, and deliver trillions of daily events to downstream systems, supporting operational dashboards, reporting, and experimentation frameworks.
• Write clean, maintainable, and well-tested code, and contribute to code reviews, design discussions, and CI/CD best practices to ensure code quality and continuous delivery.
• Automate infrastructure provisioning using Terraform and Git-based workflows to deploy scalable, containerized applications. Champion infrastructure-as-code best practices across the team.
• Ensure reliability and performance of critical services through observability (e.g., Datadog, Grafana), active monitoring, and resolution of performance bottlenecks in high-throughput environments.
• Implement secure authentication and authorization mechanisms, including SSO, RBAC, IAM policies, secrets management, and vulnerability mitigation.
• Collaborate cross-functionally with frontend engineers, data engineers, data scientists, and product managers to understand requirements and translate them into backend solutions aligned with Chewy's business goals.
• Drive a culture of technical excellence and continuous improvement through documentation and collaboration, while upholding Chewy's standards for data security, compliance, and stakeholder trust.
• Articulate complex technical ideas (e.g., why a unified metric needs a certain definition, or how a new infrastructure change will reduce latency) to both technical and non-technical stakeholders.

What You'll Need

• 5+ years of professional full-stack or backend software engineering experience, leading the design or architecture of large-scale systems in data-intensive environments, with a track record of delivering high-impact platform solutions.
• Proficiency in Java or Kotlin, with strong knowledge of building high-scale distributed systems and microservices.
• Experience building and deploying containerized applications and services using Docker and Kubernetes.
• Expertise in event-driven architecture design with a focus on scalability and fault tolerance.
• Hands-on experience with Apache Kafka or similar event-streaming platforms.
• Strong familiarity with AWS services such as EC2, ECS, CloudWatch.
• Knowledge of modern data stores and query engines including Snowflake, Databricks, Azure, or Amazon Redshift.
• Experience with Terraform and observability tools such as Datadog, Dynatrace, CloudWatch, and Grafana.
• Previous work on data platforms, experimentation frameworks, or site analytics in a high-growth or e-commerce setting.
• Proficiency in SQL databases (e.g., MySQL, PostgreSQL) for schema design, query optimization, and data modeling.
• Nice to have: Frontend development skills using TypeScript/JavaScript.

Join us to build foundational systems that power Chewy's data-driven decisions and elevate our customer experience through analytics and experimentation.
