About the role
- As a Founding Engineer, you'll work across the stack to build core product experiences and the systems behind them.
- You'll partner closely with product and design, own projects from idea → shipped → scaled, and help shape the engineering culture and technical direction as we grow.
Responsibilities
- Build 0→1 product features end-to-end: discovery, technical design, implementation, launch, and iteration.
- Use the latest AI tools every day - build with them, push their limits, and learn alongside teammates doing the same.
- Build product experiences with strong UX quality: interaction design, performance, and polish.
- Design and operate systems that scale: reliability, observability, capacity planning, cost/performance trade-offs.
- Collaborate tightly with founders and teammates, turning ambiguous problems into crisp execution.
- Strong track record building and shipping 0→1 products (startup, new product line, or major greenfield initiative).
- Ploy is building an AI-native growth engine for modern marketing teams - combining high-leverage product experiences with reliable, scalable systems.
Requirements
- Strong product sense: you can reason about user workflows, trade-offs, and "what matters" without needing perfect specs.
- Systems mindset: you enjoy making software fast, reliable, and maintainable as usage grows.
- Experience scaling products and systems through inflection points (10× traffic, new customer segments, new pricing/billing complexity).
- Experience with AI-powered products (LLMs, agentic systems, evaluation/observability, prompt/tooling pipelines).
- Experience in the web and marketing space
