Were looking for a Full Stack Engineer to join our innovation team - a small, high-autonomy group focused on discovering and building next growth engines.

This is a startup-within-a-startup opportunity: youll help take early ideas from 0→1, validate them quickly in the market, and shape what could become the companys next major product line.

We move fast and operate in ambiguity - but we do it with care. Youll build lean, production-ready prototypes that can evolve into scalable solutions, balancing speed with technical soundness. Our goal is to move fast without breaking things that matter.

Youll collaborate closely with R&D, Product, and Data teams, ensuring your experiments align with the companys architecture, principles, and long-term direction.

Who are you?
Youre a builder at heart - someone who loves turning rough ideas into working products. Youre comfortable switching between backend, frontend, data, DevOps, or QA if thats what it takes to move forward.

You thrive in uncertainty but know when to pause and build things the right way. You understand how to make pragmatic trade-offs between time to market and maintainability.

You enjoy working independently, but you also value alignment and collaboration with the broader engineering organization to ensure what you build can grow sustainably.

How will you contribute?
Build and deliver end-to-end prototypes and MVPs across varied tech stacks - from web apps to AI-driven tools.

Balance speed and craftsmanship: build for learning, but with an architecture that allows scaling if the experiment succeeds.

Collaborate with Product, Data, and R&D peers to validate hypotheses, integrate with existing systems, and share learnings.

Take ownership from ideation to delivery - including scoping, development, and feedback loops.

Contribute to a culture of experimentation, pragmatism, and technical excellence.
