As the AI Engineering Lead, you will play a key role in architecting and building complex AI systems end-to-end. This is a hands-on leadership role for engineers with high-agency and strong technical depth. We’re looking for experienced builders with a strong product mindset and a track record of shipping complex AI systems.
If you are an experienced builder who thrives at the intersection of AI, ML, data engineering, and full-stack development - this is your opportunity to set the technical direction, mentor others, and shape how users interact with AI.
We are looking for senior engineers with a strong background in SWE, AI & ML - and the capability to lead the team and grow into a founding engineer role.
Technical skillset:
Commitment & Mindset:
Leadership & Communication:
Software Stack: Typescript, Python, React, Next, Docker, Terraform, Postgres AI Stack: Vector databases, LLMs, Embeddings, observability & evals
Step 1: Intro call
Casual intro meeting with one of the founders to get to know each other and introduce Mercura
Step 2: Technical interview
💡 At Mercura, we value our applicants' time. That's why we compensate you with €50 if we ask you to complete a take-home challenge.
The technical interview consists of two parts:
For the take-home exercise, we’d provide you with a task. You’ll have 2–3 hours to complete it, focusing on data and AI engineering (e.g., NLP, embeddings, LLMs). The challenge will be based on a practical problem we’ve encountered in our day-to-day work, so it should give you a realistic sense of what the role involves.
Later, you’ll present your results to us. The presentation will include a brief algorithmic live-coding challenge, similar to a competitive programming task.
Step 3: Meet the team
Meet the other co-founders and team members to get a feel for our culture and working style.
