Job description
Amazon is establishing a NEW COSM (Central Ops Systems Management) team in Brazil — a rare
opportunity to become a founding member of a strategic function that is the foundation of Amazon's
delivery operations in the country.
What is COSM?
COSM is responsible for managing backend system configurations that underpin the entire Amazon
delivery network. COSM teams around the world — including the consolidated teams from US, Japan and
Europe — process more than 10,000 requests for configuration annually, ensuring that delivery stations,
routes, and parameters operational are always accurate and up to date
As a COSM Specialist in Brazil, you will be one of the first professionals to join this team, working directly
with established COSM teams in Japan, North America, and Europe to bring global best practices to the
unique context of the Brazilian market. This position offers a god combination: learning from
experienced teams with the freedom to build something new.
You'll perform daily configurations on Amazon's operations systems — including JAS (Jurisdiction Authority
Service), TEZCO, and other platforms — that directly impact the efficiency of delivery stations across
Brazil. Each correct configuration means packages reaching the customer faster; each documented
process means a stronger team in the future.

• Key job responsibilities
• Perform daily configuration requests for delivery stations (RGU (Regional Geographic Unit)
  configurations, jurisdictions, exclusion zones)
• Process and validate configuration changes in JAS (Jurisdiction Authority Service), TEZCO, and
  other operating systems
• Configure sort paths, pick paths, and routing parameters for various station types (Large DS,
• Exchange Points, Mini DS, EDSPs, and AMXL)
• Monitor configuration SLAs and escalate blockers for senior team members when appropriate
• Support station launches, closures, and relocations with accurate system configuration
• Maintain up-to-date documentation and SOPs (Standard Operating Procedures) for configuration
  processes
• Collaborate with Central Operations teams on scheduling and routing configurations
• Validate data accuracy before implementing changes to the production environment
• Participate in on-call rotation for urgent setup needs
• Track and report configuration metrics and ticket resolution times
• Support testing for new automation tools and provide feedback for improvements
• Assist in creating training materials and knowledge base updates
• Process configuration tickets following established procedures and defined deadlines
• Coordinate with station managers to understand specific configuration requirements

A day in the life
Your day begins by reviewing the queue for configuration tickets and prioritizing urgent requests. You process RGU updates for multiple stations, validating jurisdiction data and exclusion zones before
implementing changes to JAS. During the morning, you participate in the team's daily standup, sharing
progress and identifying blockers.
In the afternoon, you work on configurations for the launch of a new operation, coordinating with the Central Operations team to ensure that all routing parameters are correct. You test changes in the development environment before promoting them to production. It also spends time documenting a new configuration process that you optimized, contributing to the team's knowledge base.
Occasionally, you receive urgent requests that require immediate action, and your ability to work under
pressure while maintaining attention to detail is essential. You end the day by updating ticket metrics and preparing a summary for the next shift on duty.

About the team
COSM Brazil is being created in 2026 as part of the strategic expansion of Amazon's Central Operations in
Latin America. This team will be the regional hub for managing delivery system configurations throughout
Brazil — a country with continental dimensions and one of the fastest growing e-commerce logistics
networks in the world.
The COSM Brazil team will be part of Amazon's Central Operations (Central Ops) organization, which is responsible for ensuring that all operating systems in the delivery network work flawlessly, scalable, and
