About SellerMate AI

SellerMate is an AI-powered advertising and analytics platform for Amazon sellers and brands. We bring together data from across the Amazon ecosystem — Ads, Seller & Vendor Central, and DSP — and process it at scale to power automation, insights, and an AI agent that helps run our customers' campaigns.

About the role

We're looking for a backend-heavy full-stack engineer to build and scale the data pipelines at the core of our product. You'll work on how we sync, process, and serve large volumes of Amazon data — including a major project to unify and improve our account sync system. You'll own features end to end, primarily on the backend, while being comfortable touching the frontend when needed.

Responsibilities

- Build and maintain backend services on AWS (Lambda, ECS, SQS, S3).
- Design reliable data pipelines that handle queues, retries, scheduling, and large data volumes.
- Integrate with Amazon APIs (Ads, SP-API), handling authentication, pagination, and rate limits.
- Work with MongoDB, including schema design, queries, and performance tuning.




- Build and maintain REST/GraphQL APIs in Python/Flask that power our app and AI features.
- Help improve our tooling, deployments, and overall system reliability.

Qualifications

- 4+ years of backend engineering experience.
- Solid Python skills.
- Hands-on experience with AWS (Lambda, SQS, S3, or similar).
- Experience with queue-based / asynchronous systems and data pipelines.
- Comfortable working with MongoDB or a similar database at scale.
- Solid REST API design with a Python framework (Flask, FastAPI, or Django).
- Able to work independently and ship to production.

Nice to have

- Experience with the Amazon Advertising API or SP-API.
- Familiarity with data lake / analytics tools (Athena, S3, Parquet).
- GraphQL experience.
- Frontend skills with React / TypeScript.
- Infrastructure as code (AWS SAM, CloudFormation, or Terraform).
- Background in e-commerce, adtech, or analytics.
