Job description

Join Mendix, a Siemens company, as a Staff Software Engineer focused on AI Tooling, helping build the future of Generative AI.

About Mendix

Mendix is on a mission to fundamentally reinvent how applications are created. We believe in abstracting the development process, empowering everyone involved in an enterprise's digital future—from business analysts to software engineers and even CEOs—to meaningfully participate. Our goal is to create better applications faster and shape the future of software development itself.

Join Our Innovative Team

Are you passionate about the cutting edge of technology and eager to make a real impact? We're looking for a talented Staff Software Engineer to join our dynamic team and help us build the future of Generative AI.

In this role, you'll be instrumental in developing the tools, frameworks, and services that empower developers to create powerful solutions using Generative AI. Your work will span everything from tooling and evaluations to building solutions for accessing Large Language Model (LLM) providers. You'll directly influence the quality of our GenAI offerings and, in turn, enhance the lives of our customers and developers. Imagine a future where our AI tooling helps developers create higher-quality applications, faster—you'll be a key part of making that a reality.

What We're Looking For

• Strong Programming Skills: Proficiency in Python or TypeScript, with a keen interest in frameworks and backend solutions.
• Operational Expertise: Experience in an operations role, preferably with hands‑on experience in AWS and Kubernetes (K8s).
• Generative AI Knowledge: A genuine interest in and demonstrated knowledge of the modern AI landscape, including but not limited to Context Engineering, the full RAG (Retrieval Augmented Generation) lifecycle, and best MLOps practices.
• Passion for Technology: A deep passion for technology, coupled with strong problem‑solving and analytical skills.
• Agile Mindset: The ability to break down complex challenges into manageable parts and construct solutions with short, iterative feedback cycles.
• Ownership & Collaboration: A strong sense of ownership over your work, a commitment to helping your team succeed, and a love for thriving in a collaborative environment where teamwork is celebrated.

Why Us?

At Siemens Software, flexibility is how we work—hybrid by default, built on trust and autonomy. Together, 30,000 people across more than 200 countries build technology that shapes the real world. You'll grow through real projects, strong technical peers, and global mobility, backed by the scale and benefits of an industrial software leader.
