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.

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.

• 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.

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

• Experience training or deploying ML models in production.
