GNO Partners

GNO Partners builds the GNO Platform: a suite of tools that helps Amazon sellers optimize their advertising, pricing, and performance. We ingest large volumes of marketplace data daily (Amazon SP-API, Ads API, Amazon Marketing Stream) and turn it into automated bidding optimization, placement management, pricing intelligence, and monitoring that runs while our customers sleep. This is a real data-engineering and product problem, not a CRUD app.

We're hiring a hands-on engineering leader to run day-to-day delivery so our CTO can focus on architecture and product direction. You'll spend roughly half your time in the code and half running the team: prioritization, planning, 1:1s, and making sure the right things ship at the right quality.

This is a player-coach role. If you've stopped coding, or if you've never managed, this isn't the right fit.

• Delivery. Sprint planning, prioritization against business goals, estimates, and unblocking the team daily.
• Quality. Code review culture, test discipline, and production reliability of our ingestion pipelines and scheduled jobs.
• People. 1:1s, onboarding, growth conversations, and first-round hiring screens as the team scales.
• Shipping code. You'll carry meaningful features yourself, especially early on; that's how you'll earn the team's trust.

The CTO retains technical vision, architecture direction, the hiring bar, and infrastructure strategy. You two will work as a pair, not a hierarchy of approvals.

• TypeScript end to end (strict mode)
• Backend: NestJS API, Temporal workflows for data ingestion and background monitoring
• Frontend: React, TanStack Router/Query, AG Grid, Tailwind
• Data: Postgres (Supabase), AWS data warehouse (Iceberg, Athena)
• Integrations: Amazon SP-API, Amazon Ads API, Amazon Marketing Stream
• AI: LangChain/LangGraph with LLM-powered features in production
  

• 7+ years as a software engineer, with 2+ years leading a team of 3-8 while still shipping code
• Deep TypeScript/Node.js experience; you can review a NestJS service or a React data grid and give substantive feedback the same day
• Experience with data-heavy systems: high-volume ingestion, background job orchestration, or warehouse/analytics pipelines
• You've run delivery before: planning, scoping, cutting the right corners, and saying no
• Comfortable being the #2 technical voice; you'll challenge the CTO in private and align in public
  

• Temporal (or similar: Airflow, Step Functions) in production
• Amazon marketplace ecosystem experience (SP-API, Ads API, seller tools)
• E-commerce, ad-tech, or analytics product background
• Experience introducing lightweight process to a team that previously had little
  

• Roadmap items ship predictably without the CTO's day-to-day involvement
• You've personally shipped features across the API, worker, and frontend
• The team knows what they're working on this week and why, and quality has gone up, not down
