Senior Software Engineer

WHY SHUTTLEBASE?

Imagine websites that rebuild themselves on autopilot to sell more, convert better, and grow faster. At Shuttlebase, we’re making that happen — merging generative AI, large-scale data pipelines, and experimentation into a self-evolving web.

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.
