Senior AI Engineer (with a Software Development Background)

Hi 👋🏽 I’m Stijn, AI Engineer at Altura
You’ll find the standard role details further down, but first, here’s the essence: our current context and why we’re hiring an additional AI Engineer.

Why We’re Hiring

We’re a small, fast-moving team with more AI ideas than we can currently bring to life. We’ve secured the budget via a series A (yay) to add another senior AI engineer who can help us turn those ideas into reality: someone experienced enough to drive change, push projects forward, and shape how we build and scale our AI capabilities.

We’re mature enough to give you a strong foundation—production traffic, customers who love our product, real infrastructure—but still early enough that your ideas will shape how we work and what we ship.

If you’ve ever been frustrated by slow decision-making, endless meetings, or layers of approval that keep you from building at speed, you’ll like it here. We value engineers who thrive on solving tough technical challenges, push through complexity, and deliver meaningful progress without the bureaucracy.

You’ll have the room to experiment, own big pieces of our AI roadmap, and help us define what great engineering looks like as we scale.

TL;DR

We are looking for a Senior AI Engineer with a software development background. You’ll turn the latest AI breakthroughs into real product features. You will apply state-of-the-art AI techniques (LLMs, RAG, fine-tuning, agents) to concrete business problems in bid management. You’ll have the freedom to experiment rapidly, prototype bold ideas, and turn the most promising ones into production features that are used by customers in days, not months.

This is the role for someone who loves being at the frontier of AI: trying, testing, breaking, building, and who wants to see their ideas shape a fast-growing SaaS product.

Our Tech Stack

• Frontend: Vue / React
• Backend: .NET, Python (FastAPI)
• AI: Azure OpenAI, Pinecone, BM25, FastText, LangChain, Azure ML, Cosmos DB, Langfuse
• Infra: Fully integrated within Azure DevOps (CI/CD, pipelines, containers)

The role and your challenge

Over the past year, we’ve built out core retrieval-augmented generation pipelines that automate knowledge search and document processing for tenders. Based on this foundation, we build many AI automations like custom summaries and automatic requirement answering on tenders. We’ve proven that AI can fundamentally change how bid teams work.

Now we’re scaling up: we want to explore and productize new AI capabilities at speed. That’s why we’re looking for you!

You will

• Build and iterate on RAG pipelines, agents, and LLM-based workflows.
• Prototype with frameworks like LangChain, OpenAI function calling, or whatever tomorrow’s standard will be.
• Work closely with backend engineers to move from “scrappy prototype” to “production feature.”
• Own experiments end-to-end: from idea → POC → deployed feature → learnings.
• Ensure scalability, performance, and maintainability without slowing down experimentation.
• Contribute to the growing AI platform foundation we’re building inside Altura.

You have

• Proven software engineering experience in SaaS and strong knowledge in Python and related frameworks (bonus: experience with .NET or fullstack).
• Solid understanding of modern LLM applications (RAG, embeddings, vector DBs, agents).
• Solid experience with evaluating and testing LLM applications.
• Experience with cloud-based ML/AI workflows (Azure ML, AWS Sagemaker, or similar).
• Familiarity with tools like Pinecone, Langfuse, or open-source alternatives.
• A hacker’s mindset: you love to try, break, fix, and ship.
• Curiosity about the latest in AI and the drive to apply it to real business problems.

You Should Apply If

• You love high-impact roles where you can collaboratively build processes as we scale.
• You want to feel like your work matters and see tangible results in weeks.
• You thrive in environments that reward creativity and independence.
• You get energy from solving uncharted problems with cutting-edge AI tools.

You Should Not Apply If

• You prefer long research cycles over rapid prototyping.
• You need strict role definitions and close supervision.
• You are afraid of failure — here we test, fail fast, and try again.

We offer

• Work: Be part of an AI-built SaaS startup going scaleup 🚀
• Compensation: Competitive salary and Virtual Stock Units (VSUs) 💸
• Free: 26 vacation days 🏖️
• Tec: All the tools and tech stack you want 🛠️
• Flexibility: Work remotely when and how you want 🔄
• Grow globally, Learn locally: we work in English but offer free weekly Dutch lessons 🌍
• Fun: Speed at the go-kart track or bowl your colleagues out during our company outings, but feel no need to join 🏎️
• Development: Grow your skills with a budget you can unlock by presenting a case to leadership tied to our OKRs💡
• Laptop 💻
• Hybrid working: 2 days/week in our beautiful Amsterdam office 🏫
