Founding Engineer

Full-Stack Founding Engineer

Hiring a full-stack founding engineer to join our team and focused on product engineering and shipping new features.

Architecting and implementing full-stack product features in Typescript/React/Node is the core of what you'll be doing. Real examples include:

• Build out agentic workflows that design, build, and optimize online shops
• Build out product & payments processing infrastructure
• Launch analytics infra on Clickhouse/Kafka that support billions events/month

• Is proficient in Typescript/React/Node
• Uses Cursor/Claude Code to accelerate their work
• Has built products 0 -> 1 with real users and revenue
• Is OK operating independently without product/design
• Is ALWAYS SHIPPING. We don't spend weeks planning features at Replo
• Has a product and customer-focused mindset
• Has experience being burned by deployment and maintenance issues. If you have a strong opinion on how products should be built, that's good
• Values writing clean, maintainable software, including documentation (e.g. the code needs to be correct and run fast, but we're the ones that have to read it and understand it)
• Is comfortable with ambiguity and defining software architecture patterns to solve customer pain points

• Have a CS degree or formal computer science/STEM backend
• Have started a company before
• Enjoy attending hackathons
• Worked at an early-stage (Series A or earlier) startup previously
• Have not wasted hours interview-prepping on Leetcode
• Have an eye for visual design (or past experience in product design, Figma, etc).
