https://www.doubleo.ai/ exists to give non-technical people the superpowers of elite AI engineers. Born from years of experience building award-winning AI tools for product teams, we’ve developed a powerful platform that allows anyone to build intelligent automations — no coding required.
Founded by leaders from Meta, Rippling, and PlayStation, and backed by top Silicon Valley investors, we’re an engineering-led company pushing the boundaries of what AI can do in real business workflows.
We’re looking for a Full Stack AI Engineer to join our tightly-knit AI team. You’ll build internal tools and customer-facing AI agents end-to-end — from back-end logic to UI, from prompt design to LangChain flows.
You’ll be part of a team where everyone is an AI engineer. We don’t silo frontend/backend or infra/data. Instead, we move fast, write 50% of our code with AI tools, and ship useful agents that save users real hours every day.
- Build full-stack AI applications using Python, LangChain, and LangGraph;
- Work on both internal workflows and external, user-facing agent tools;
- Develop and deploy RAG systems and LLM-powered agents;
- Own features end-to-end — from problem scoping and prompt design to database modeling and UI;
- Collaborate with a small, senior team to prototype quickly and ship constantly;
- Leverage AI tools to move faster and write better code.
- 5–6 years of total software engineering experience, including full-stack development;
- Hands-on with AI tools: comfortable building with LLMs, LangChain, and RAG;
- Hands-on experience. You still write and ship code daily. You’re curious, fast, and obsessed with learning;
- Strong Python skills, with bonus points for exposure to React or similar front-end tools;
- Have 2-3 years of LangChain experience;
- Familiar with building intelligent workflows or automations, not just CRUD apps;
- Bonus: experience with cloud infra, vector DBs, or fine-tuning LLMs.
- Full-time job. Please note that we won’t consider candidates planning to combine this job with another one.
- Remote work. You may be located in almost any country, just need a good Internet connection, a computer to work from, and the opportunity to adjust your working schedule for the team.
- Work with some of the brightest minds in AI from companies like Meta and Rippling.
- Join an early team with a massive impact on product and culture.
- Build things that people use immediately, not in quarters.
- Salary will be discussed during the interview. Paid in USD.
Application deadline: ASAP.
