Software Engineer III

Location: San Mateo, CA, United States; Hybrid

Role Overview:

We’re seeking a Software Engineer III to design and build scalable backend services, data pipelines, and master data management (MDM) solutions that power our next-generation e-commerce platform. You’ll play a key role in developing the foundational data and services layer that enables reliable, consistent, and high-quality data across the enterprise—driving business growth, operational excellence, and AI-powered innovation. 

As a Software Engineer III, you’ll work independently on complex backend and data engineering problems and produce high-quality code with minimal oversight. You’ll triage production issues, contribute to root cause analysis, and maintain comprehensive technical documentation. Your expertise in distributed systems, data modeling, integration patterns, and AI-augmented development will be instrumental in delivering reliable, scalable solutions. You consistently demonstrate technical excellence, take ownership of your work, and communicate effectively with cross-functional teams. You’re proactive in identifying and resolving issues, passionate about data quality and governance, and committed to raising the quality bar.

What you’ll do:

• Design and build scalable backend microservices, data pipelines, and integration services with minimal oversight, ensuring high code quality, reliability, and performance
• Develop and maintain master data management solutions that ensure consistency, accuracy, and governance of core business entities across the enterprise
• Write modular, testable, resilient, production-grade code with strong attention to edge cases, idempotency, and data integrity
• Design and implement data models, schemas, and APIs that support domain-driven design principles and composable, event-driven architectures
• Leverage AI/ML tools (Claude Code, GitHub Copilot, etc.) to enhance developer productivity, automate data quality checks, and integrate intelligent capabilities into data workflows
• Implement and optimize RESTful/GraphQL APIs and event-driven integrations (Kafka, message queues) with internal and third-party systems
• Effectively debug and resolve production issues across distributed systems. Identify and communicate potential risks. Participate in Root Cause Analysis (RCA) sessions
• Collaborate effectively with architects, data engineers, product managers, and domain stakeholders. Clearly communicate technical information to both technical and non-technical audiences

What you bring to the team:

• Bachelor’s degree in Computer Science, Data Science, or equivalent practical experience
• 3 – 5 years of experience in software development with a strong focus on backend systems, data engineering, or data platform development
• Mastery of at least one modern programming language (e.g. Go, Python, Java) with deep understanding of algorithms, data structures, concurrency, and optimization
• Expertise in building RESTful/GraphQL APIs, microservices architecture, and event-driven systems (Kafka, SNS/SQS)
• Strong understanding of data modeling (dimensional, relational, graph), schema evolution, and data governance practices including master data management concepts: entity resolution, data stewardship, golden record creation, and cross-system data synchronization
• Strong knowledge of SQL (PostgreSQL, MySQL) and NoSQL databases (Cassandra, MongoDB, Redis), with experience in data warehousing platforms (Snowflake, Redshift, BigQuery) and data lake architectures
• Experience with AWS (or other cloud providers) utilizing services such as EC2, S3, Lambda, Step Functions, Glue, EMR, and ECS/EKS. Understanding of infrastructure-as-code (Terraform, CloudFormation) and CI/CD pipelines
• Proficiency using AI-powered development tools (Claude Code, GitHub Copilot) for code generation, refactoring, and documentation. Understanding of prompt engineering and LLM integration patterns for building AI-augmented data workflows
• Experience in retail, ecommerce, or consumer goods industries preferred. Strong problem-solving and debugging skills across distributed backend systems, data pipelines, and integration layers
