About Benji

Benji is building the infrastructure layer for loyalty and brand connectivity. We enable companies to integrate, launch, and scale loyalty experiences across partners through a single platform -turning fragmented ecosystems into programmable networks.

We work with leading enterprise brands and move fast to bring new partnerships and integrations to life.

The Role

We’re looking for a Senior Backend Engineer (or full stack with a strong backend emphasis) to own core platform services and help define how we build software in an AI-native way.

This role sits at the intersection of:

• Backend platform engineering
• Distributed systems & event-driven architecture
• Partner integrations & API design
• AI-powered engineering workflows

You will:

• Design, build, and extend Benji’s Python microservices across campaigns, users, rewards, orders, and partner integrations
• Own event-driven workflows, data integrity, and cross-service orchestration at production scale
• Build and evolve AI-native engineering standards - agents, MCP tooling, and LLM-powered product workflows

This is not a maintenance role - you’ll be building the core infrastructure that powers loyalty flows for enterprise brands.
