Job description

WHO WE ARE

We’ve built an AI-native internal platform that powers every aspect of our Amazon brand management business. AI isn’t a feature — it’s the backbone.

• LLMs classify and respond to inbound communications
• AI generates pre-call intelligence briefs from raw enrichment data
• A RAG system feeds context into every generation pipeline
• An AI checkpoint system audits all generated content against quality gates
• The platform is already live and scaling fast:
  • 17+ background services
  • 130+ frontend pages
  • 214 backend services
  • 184 database tables
  • Dozens of autonomous AI pipelines

OUR CORE VALUES

Be A Moral Human

Serve a higher purpose. Everything we build and every decision we make is grounded in doing the right thing.

Improve 1% Daily

Strive for 1% better every day. Consistent, compounding improvement is how we build world‑class systems and teams.

Extreme Ownership

Own your actions. No excuses, no hand‑offs as a crutch. If it’s in your world, it’s your responsibility.

Solve Problems, Don’t Create Them

Every challenge has a solution. Don’t slow down the team by creating new problems — come with answers, not blockers.

Make an Impact

Focus on meaningful results. We measure success by the difference we make, not the hours we log.

Fail Fast & Fail Forward

Don’t be afraid to fail. Take that failure, learn from it, and move forward stronger. Every failure is a lesson.

Trend Intelligence Engine

• Process RSS feeds, social media, video platforms, and search trends
• Generate reports, forecasts, and content drafts
• Run autonomously on scheduled jobs

Content Quality Pipeline

• Extend the multi‑agent system (outline → audit → generate)
• Maintain binary quality gates (PASS/FAIL with citations)
• Support multiple content formats across the pipeline

Automated Lead Qualification

• Enrich leads with product data and market insights
• Build AI scoring and qualification grading systems
• Generate automated audit reports

AI Executive Assistant

• Build and maintain Slack‑integrated operations
• Automate scheduling workflows
• Triage and respond to email autonomously

DAY-TO-DAY RESPONSIBILITIES

• Build and improve AI pipelines for client performance insights

• Add tool use / function calling for real‑time data in LLM pipelines
• Debug classification errors and improve model accuracy
• Optimize LLM costs, latency, and performance
• Build dashboards for AI metrics and usage monitoring
