Founding Engineer

Overview

Sapyon is building the real-time optimization layer for Amazon advertising: hourly analytics, budget automation, keyword intelligence, and ranked AI actions in one platform. As a Founding Engineer, you’ll shape architecture and ship the systems advertisers depend on.

This is an early-stage role: broad scope, direct impact on product direction, and the chance to set engineering standards while we scale.

Responsibilities

• Design and build core product surfaces and backend services end-to-end
• Own reliability and performance for data pipelines fed by Amazon Marketing Stream
• Implement automation engines (budget rules, keyword actions, recommendation flows)
• Make pragmatic architecture decisions that stay simple as we grow
• Collaborate closely with design and go-to-market on what to ship next
• Raise the bar on code quality, observability, and operational hygiene

Requirements

• 3+ years building production software (startup or high-ownership environment preferred)
• Strong in at least one modern stack (e.g. TypeScript/Node, Python, Go) and solid SQL
• Experience shipping full-stack features, including APIs, data models, and customer-facing UI
• Comfort with ambiguous problems and turning them into clear technical plans
• Bias for shipping, measuring, and iterating with real users

Nice to have

• Streaming data, event-driven systems, or time-series analytics experience
• Prior work in ads, e-commerce, or B2B SaaS
• Infrastructure familiarity (AWS, containers, CI/CD)
• Interest in AI-assisted product features grounded in real metrics
