ABOUT THE ROLE

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

THINGS YOU'LL BE WORKING ON

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

Platform

  • Building sandbox infrastructure for our agents (managing secrets, proxies, and compute)

  • Building an eval framework for our models

  • Launching an analytics platform on ClickHouse/MSK that consumes millions of events per day

  • Building an agentic workflow orchestration architecture

  • Building a public API for Replo/Slack bots

  • Overhauling our billing system to support arbitrary usage-based billing

Programs

  • Enabling customers to buy domains directly through Replo

  • Building agent-driven insight reporting for businesses

  • Building a full product-customizer UI for custom print-on-demand products  

LOOKING FOR SOMEONE WHO

  • Can be in office 4-5 days/week in San Francisco

  • 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 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

BONUS POINTS IF YOU

  • Have a CS degree or formal computer science/STEM backend

  • Have started a company before

  • Enjoy attending hackathons
