.About the team

The Seller Acquisition & onboarding team is the backbone of the Marketplace
ecosystem. We are responsible for architecting and scaling the global platform that powers the end-to-end seller journey. Our mission is to build seamless, high-performance systems that manage:

• Global Onboarding & Sales Funnels: Engineering robust pipelines to bring millions of diverse sellers onto our marketplace with minimal friction.

• Intelligent Activation Flows: Building automated, data-driven workflows that accelerate seller time-to-market and drive early-stage success.

• Full-Lifecycle Program Management: Designing complex tools and services that allow for the sophisticated management of seller programs at a massive global scale.

What You’ll Do

• Architectural Leadership: Design and deploy enterprise-grade, full-stack solutions that act as the primary system of record for global operations.

• Technical Strategy: Lead the transition from reactive task execution to proactive, "agent-aware" architectures, identifying efficiency gaps before they impact the business.

• Hybrid Engineering: Own and write high-performance code across the stack, utilizing Java and Python to build robust middleware and backend services.

• Infrastructure & Cloud: Manage and optimize cloud connectivity—specifically within GCP or AWS—using tools like Dataflow, Pub/Sub, or BigQuery to power real-time data synchronization.

Mentorship & Excellence: Serve as an "Example of Excellence," guiding the team’s technical evolution and fostering a culture of "Quality at Source" through rigorous code reviews and global engineering standards

Cloud & Infrastructure (AWS/GCP)

• Cloud-Native Architecture: Proven track record in building serverless and containerized applications using AWS Lambda/Fargate or GCP Cloud Run/GKE.

• Infrastructure as Code (IaC): Mastery of Terraform, Pulumi, or CloudFormation for managing immutable infrastructure.

• Reliability Engineering: Experience implementing the Circuit Breaker pattern, Retry logic with exponential backoff, and Bulkheading to ensure system resilience.

Distributed Systems & Data

• High-Volume Messaging: Deep expertise in event-driven architectures using Apache Kafka, RabbitMQ, or Google Pub/Sub for asynchronous processing.

• Database Excellence: Advanced proficiency in both SQL (PostgreSQL/MySQL) and NoSQL (DynamoDB/MongoDB/Cassandra). Understanding of schema design, indexing strategies, and query optimization.

• Observability & Tracing: Experience with distributed tracing (Open Telemetry, Jaeger) and centralized logging (ELK stack or Datadog) to monitor complex request paths.

Security & Governance

• Identity Management: Implementation of robust auth protocols including OAuth 2.0, OpenID Connect (OIDC), and JWT-based stateless authentication.

• Security First: Expert knowledge of web security best practices (OWASP Top 10), including SQL injection prevention, XSS mitigation, and data encryption at rest and in transit.

Strategic & Leadership Skills

• System Design: Ability to architect systems for global scale, handling trade-offs between consistency and availability (CAP Theorem).

• Modern DevOps: Mastery of CI/CD orchestration (GitHub Actions, Jenkins, or GitLab CI) and container orchestration with Kubernetes.
