Full Stack Product Engineer
Remote · San Francisco
Own products end to end.
Doublespeed is building the infrastructure to capture attention at scale. We tinker constantly to try and push the limits of what we call social agents.
You’ll work directly with founders, move at machine speed, and have real ownership over what we build and how it feels.
We’re looking for someone who’s strong with TypeScript, React, and Node, comfortable with databases and infrastructure, and obsessive about craft and velocity.
Bonus points for experience with high-volume systems, AI tooling, or anything that has had to scale to millions of operations.
What you'll do
Ship features across the terminal end to end: bulk content creation, persona management, scheduling, the workflow builder
Wire image, video, audio, and language models into reliable, repeatable production pipelines
Build integrations with social platforms and the device fleet that posts on them
Own surfaces from schema to API to UI, and keep them fast, cheap, and reliable
Instrument what you ship and iterate based on how operators actually use it
Make good architectural calls under real constraints of cost, latency, and scale
Tools and Context
TypeScript, React / Next.js, Node in production
Postgres and SQL
Background jobs, queues, and schedulers
AI model APIs across image, video, audio, and language
Cloud infrastructure
