Senior SW Engineer (Full Stack)

We’re a well-funded, very early-stage startup with a massive vision. Joining now means you’re not just an employee — you’re helping set the technical and cultural DNA of the company. If you’ve ever wanted the autonomy of a founder with the backing of top-tier investors, this is it.

What You’ll Build & Achieve

As our Senior Fullstack Engineer, you’ll be hands-on across the stack — designing, building, and scaling systems that power our AI-driven platform. Expect autonomy, speed, and a ton of ownership.

• Architect and build scalable systems — from backend APIs to frontend dashboards — that process tens of millions of web events per day.

• Design large-scale data infrastructure that explains how websites are built, why they perform the way they do, and how to optimize them.

• Train and integrate LLMs into production to automatically hypothesize, generate, and validate website variants.

• Shape engineering culture & practices — your fingerprints will be all over our tech stack, architecture, and team processes.

• Experiment, prototype, and iterate — research + product + AI + scale, all at once.

This isn’t about maintaining yet another SaaS app — it’s about building an AI engine that redefines how digital products are created.

Who We’re Looking For

• A software craftsman — you write clean, scalable code and know how to ship at speed.

• 5+ years fullstack experience (Python, JS, AWS preferred, but not a blocker).

• Experience leading teams or driving major projects.

• Background in CS, EE, Math, or equivalent hands-on mastery.

• An AI enthusiast who wants to build with LLMs and shape how they’re applied in the real world.

Bonus Points:

• Startup experience (you thrive in zero-to-one).

• Experience training or deploying ML models in production.
