Ivy is an open-source developer platform for building internal business apps using pure C#. Connect your database, and our AI-powered engine generates the full-stack app in minutes.

We need an exceptional Founding AI Engineer to lead the development of our generative code engine and push the limits of what AI can do for developers.

Why Join Ivy

At Ivy, we’re not just building another framework—we’re sparking a revolution in how developers create internal business tools. We’re AI-first, open-source, and ready to take on the slow-moving giants of enterprise software. Here’s why you’ll want to jump on board:

• Ride the AI Wave: Help shape the future of tech by building tools that make AI accessible and powerful for developers everywhere.
• Empower Developers: We’re not here to replace coders—we’re here to make them superheroes. Your work will amplify what developers can achieve.
• Open Source, Open Minds: Contribute to a thriving open-source community where your code can impact developers worldwide. Your ideas will shape the future of enterprise software.
• Challenge the Giants: Take on the SaaS behemoths and traditional software dinosaurs. We’re nimble, innovative, and here to win.
• Impact: You’ll work directly with the founders, ship code that reaches users the same week, and help define the foundation of both the product and the company.
• Compensation: We pay at the top of the market—cash and equity—and reward performance better than any other tech company in Sweden.
• Balance and Thrive: Flexible hours, epic team retreats, and a culture that values your life outside of code.

Ready to join a team that’s by developers, for developers, and prepared to redefine enterprise software? Ivy’s where the future’s being built.

What we’re looking for

• You’re a seasoned engineer with hands-on experience building or fine-tuning LLM-based systems.
• You're fluent in C# and understand how to generate idiomatic, safe, and useful code.
• You have strong opinions on code generation UX, model prompting, evaluation, and safety.
• You want to build systems that developers trust, use daily, and fall in love with.
• You thrive in early-stage environments where speed, ownership, and creativity matter.

Your responsibilities

• Build Ivy’s generative engine for producing clean, structured C# code.
• Design prompt chains, templates, and feedback loops to improve generation quality.
• Integrate AI seamlessly into the developer experience—without magic or hallucinations.
• Own evaluation: automatic tests, developer feedback, and continuous improvement.
• Collaborate with product and engineering teams to ship production AI features.
• Fine-tune and experiment with custom models and domain-specific optimisations.
• Contribute to building a developer-first AI UX grounded in trust and control.
• Help us recruit and mentor a world-class AI/ML team.

Our recruitment process
