About Pyyne

Pyyne is a modern technology consultancy engineering the next generation of digital products and services.

About The Role

Our client is an AI-powered growth intelligence platform for DTC brands, aggregating data from Meta, Google Ads, Shopify, TikTok, and Klaviyo with Claude AI layered on top for analysis and content generation.

The platform was built by a non-technical founder using AI-assisted tools and is not yet production-ready. This engagement is focused on turning it into a properly functioning, production-grade SaaS product with a real path to market. The current codebase has meaningful functionality but requires a disciplined engineering hand to harden, complete, and scale. We’ve done the due diligence, reviewed the code, and begun making the appropriate changes, now we need a full time dev to come in and own the product.

You'll be the sole engineer on this project, working directly with product stakeholders. You'll own the full technical roadmap and execution.

A discovery phase is currently underway. The new engineer on this project will receive a technical handoff and prioritized backlog before work begins.
