[Hiring] Full Stack Software Engineer @GNO Partners

Role Description

You'll be a core engineer building out the next generation of our platform. Day to day, that looks like:

• Building new report tools end-to-end: from ingesting Amazon reports (CSV/Excel uploads today, APIs soon) to aggregating data across sources and producing the bulk operations files clients use to make changes on Amazon.
• Owning features across the stack: NestJS APIs, Postgres data models, React frontends, and the AWS plumbing that ties it together.
• Working closely with our team to translate Amazon seller workflows into clean, reliable software.
• Contributing to our shift toward fully automated data flow with Amazon SP-API and Ads API.
• Helping integrate AI-powered insights into reports as we build that layer out.

Qualifications

• 3-5 years of full-stack experience shipping production software.
• Strong with TypeScript, Node.js, NestJS, and React.
• Comfortable with Postgres / Supabase — you can model data well and write queries that don't fall over at scale.
• Working knowledge of core AWS services: S3, Lambda, EC2, SNS, SQS.
• Basic familiarity with AI agentic systems — you've built or experimented with LLM-powered features, tool-use, or agent workflows. You don't need to be an expert, but you should be curious and ready to build in this space.
• Pragmatic, ownership-driven, and comfortable making decisions with incomplete information.
• Clear written communication — we work async across time zones.

Requirements

• Experience with Amazon Seller Central, SP-API, or Ads API.
• Background working with large CSV/Excel datasets or report aggregation pipelines.
• Prior work on B2B SaaS or analytics platforms.

Benefits

• Real ownership over features that ship to paying clients.
• A small, senior team where your work is visible and impactful.
• Clear roadmap with meaningful technical challenges ahead — APIs, pipelines, and AI.
