* Work directly with AI/ML systems, web agents, and full-stack development.
* Shape the technical architecture and culture of a fast-growing YC-backed startup.
**You will be a perfect fit if you…**
* Have 2+ years of backend engineering experience and a solid foundation in both Computer Science and software engineering principles. We're also open to exceptional college grads with strong intern/co-op experience.
* Are fluent in Python and TypeScript and have worked with FastAPI and/or NextJS in the past.
* Understand how databases (KV, SQL, Document based) work, when each of them should be used and how they can be optimized.
* Have previously developed, tested and scaled RESTful APIs in the past.
* Are self-motivated, like to take ownership, have low ego; desire to work on a fast-paced, intense, fun team. Passion for building a world-class engineering culture.
* Are product-focused, understanding that technology is a means to build an amazing product, not an end in itself.
* Value code quality, but are pragmatic, shipping fast when needed.
* Are excited about AI/ML applications and have previously worked in LLMs, agents, and automation
**Nice to have:**
* Knowledge of OOP design patterns, clean architecture, event sourcing and Test Driven Development.

* Thorough knowledge of the Linux operating system.
**About our hiring process:**
1. 30 minute interview with a founder to discuss your background
2. If we think you are a potential fit, we will send you a take home assignment.
3. One hour interview diving into your take home submission where we’ll ask you about your solution, etc.
4. Final interview with the full team.
**What it means to join the team:**
* **Own the engine room**. Architect and ship the core services that power our multi-agent AI workflows: rock-solid restful APIs, data models built for evolution, and deployment/debug tools that just work.
* **Be the go-to expert.** Troubleshoot critical issues in production, mentor peers on system design, and evangelize best practices across services and languages.
* **Move at startup speed.** Partner directly with customers: jump on customer calls, diagnose pain points, and deliver impactful improvements in hours, not quarters.
