The Company

Our client is a highly-funded, high-growth scale-up building AI-powered products that address real-world enterprise challenges. Backed by top-tier investors with a recent $50M Series A, they are redefining how companies deploy AI in production.

You will be joining a highly talented, global engineering team that values ownership, thoughtful execution, and speed.

The Product

The company has built a breakthrough Managed AI Delivery Platform. Instead of generic AI wrappers, they deliver highly tailored AI solutions to large enterprises in days, not months.

At the core of the platform is a unique architecture of deep technical building blocks—spanning search, reasoning, agents, and automation. These blocks are dynamically orchestrated by a "Blueprint" (a spec file) customized for each specific enterprise use case.

The product connects securely to any data source (SaaS, APIs, databases, files) and is entirely LLM-agnostic. It enables enterprises to deploy complex AI features like automated workflow triggers, deep data extraction from unstructured files, and AI-native observability dashboards. Crucially, it does all this without requiring model fine-tuning and without sharing data outside the customer's secure perimeter.

️ The Role

As a Full Stack Software Engineer, you will be at the heart of this product engine. You will work across the stack to design, implement, and ship the high-quality workflows, reusable components, and internal tools that allow the platform to scale.

This is a high-ownership role where you will take features from idea to production. You will collaborate directly with product teams and enterprise customers to tailor specific solutions, extending the platform and UI/UX layer as needed. If you love seeing your code in production within days and want to build the infrastructure that makes rapid, enterprise-grade AI possible, this is the team for you.
