Loop Earplugs is reinventing how people experience the world by enabling them to live life at their own volume. 2024 was a pivotal year at Loop – we hit 14,000,000 earplugs sold, were named ‘The Best Earplugs for Concerts’ by The New York Times, and expanded our product offering to a complete range of solutions for day and night. Oh – and not to mention making history as the first company to win Deloitte’s Fast 50 Belgium twice.
But this is just the beginning. As we continue to develop disruptive products, we’re constantly on the lookout for the next big idea - and building a team who can make it happen.
Being a Looper means making a difference. Whatever your role, this is your stage to make a real impact and bring your ideas to life. Better yet, you’ll join a fast-growing, global team of 250+ people who are passionate, down-to-earth and eager to tackle challenges together.

Build AI-driven systems and help transform how teams work at scale.
As a Senior AI Engineer, you play a critical role in transforming how teams operate by developing AI-driven tools that solve real business challenges. You work closely with stakeholders to turn complex needs into simple, scalable solutions. Whether it’s automating customer feedback analysis, streamlining campaign workflows, or building tools that improve asset creation, your work directly influences how teams operate. You combine deep technical expertise with business understanding to drive measurable impact across the organization.
The roleYou take full ownership of designing and shipping production-ready AI systems from scoping to deployment. You build solutions that automate workflows, accelerate decision-making, and create efficiency across teams. Using NLP, LLMs, and agentic workflows, you translate business problems into intelligent systems that are reliable and scalable.
You select the right technical stack — Streamlit, FastAPI, Azure, or GCP — and ensure strong integration, adoption, and measurable outcomes. In this senior role, you help define engineering standards, guide architectural decisions, and elevate how AI solutions are built and deployed.
What you’ll do
- Design, develop, and deploy AI-driven systems integrating NLP, machine learning, and automation
- Lead end-to-end ownership of AI products from opportunity identification to production deployment
- Build applications using frameworks such as Streamlit, Gradio, or FastAPI
- Create integrations via APIs and webhooks to connect AI solutions with internal systems
- Fine-tune and evaluate LLMs for specific business use cases
- Define technical standards and contribute to best practices for AI development and deployment
- Monitor, optimize, and scale AI systems through strong MLOps practices
You won’t
- Deliver experiments without production follow-through
- Build systems without clear performance or adoption metrics
- Overengineer solutions that should remain simple
- Avoid accountability for technical direction and outcomes
How you’ll succeed
You combine technical depth with ownership and clarity. You are comfortable defining architecture, setting standards, and driving projects independently. You communicate complex concepts in a simple way and align stakeholders around practical solutions. You move between experimentation and production with discipline. You measure success through adoption, performance, and efficiency gains. You stay current with AI developments and apply them responsibly to improve systems and workflows.
What you’ll bring
- 7+ years of experience building AI/ML solutions, with strong production experience
- Degree in Computer Science or a related technical field
- Advanced proficiency in Python and ML frameworks such as PyTorch and scikit-learn
- Strong experience with NLP, LLMs, and modern GenAI approaches (RAG, agentic workflows, tool use, multi-modal systems)
- Experience with data preprocessing, model evaluation, and performance optimization
- Hands-on experience with CI/CD, Docker, Kubernetes, and cloud platforms (preferably Azure or GCP)
- Experience with MLOps, including monitoring and scaling AI systems
- Ability to lead technical direction and mentor others
Loop isn’t for everyone. We might not be a match if you:
- Prefer experimentation without production responsibility
- Avoid defining architecture or setting technical standards
- Struggle to connect AI systems to measurable business impact
- Feel uncomfortable taking ownership of end-to-end delivery

What We Do
Our story began when Loop's founders, Maarten and Dimitri, had a common problem: ringing ears after a night out. They discovered that they were not alone, as 1 in 4 adults suffer from hearing damage. But why weren't they wearing earplugs? This question sparked the inception of Loop. At Loop, we are dedicated to revolutionizing the way earplugs look, feel, and sound. Whether you need hearing protection or simply want to ensure comfort for your ears, Loop allows you to live life at your own volume. Based in Antwerp with offices in Amsterdam, New York, and Shanghai, we are a rapidly growing team of over 250 people. .
