  • Build and optimize media handling pipelines (image/video upload, compression, CDN delivery via CloudFront).
  • Architect and tune database schemas (Postgres  DynamoDB single-table design) with focus on cost-efficient scale.
  • Collaborate with mobile/frontend engineers to deliver seamless, low-latency user experiences.
  • Engage in the full software development lifecycle: design, coding, testing, deployment.
  • Work in a fast-moving, agile startup environment - iterating quickly and adjusting priorities based on learning and feedback.

  • Experience with relational databases (Postgres/MySQL) and exposure to NoSQL systems.
  • Track record of shipped products or platforms we can see live today.
  • Leadership ability, self-motivation, and comfort navigating ambiguity.
  • Ready to operate with founder-level ownership and commitment.
  • Bonus: Experience with real-time data pipelines, cloud infrastructure (AWS), or consumer apps.
  • Bonus: Demonstrated experience building or scaling marketplace platforms with integrated logistics flows (matching, routing, ticketing, or fulfillment systems). e.g. Uber, Lyft, Airbnb, or Doordash.
