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. #J-18808-Ljbffr HRB
