About us

SenTech AI is an early-stage deep-tech startup building AI-driven products at the intersection of wellness, sensor technology, and everyday digital experiences. We're a small, ambitious team that moves quickly, values clear thinking, and builds real products that reach real users. As an intern with us, you'll be close to the work that matters — not on the sidelines.

About the role

We're looking for a Product Design Intern to help us turn ideas into working products — websites, mobile apps, and other digital applications. A defining part of how we work: we don't write code by hand — we build with AI tools. We're looking for someone genuinely curious about how to use AI tools to design, prototype, and ship real products , rather than someone who wants to spend the day programming.

This is a great fit if you enjoy thinking through what to build and why , breaking messy problems into clear steps, and figuring out how modern AI tools can bring an idea to life.

What you'll do

• Help translate ideas and user needs into clear product concepts and requirements
• Prototype and build products (web, mobile, and beyond) using AI-powered development tools
• Research users, competitors, and market trends to inform product decisions
• Break down complex problems into structured, logical plans
• Work closely with the founder and team to test, iterate, and improve

What we're looking for

• A background in a STEM / technical field (engineering, sciences, mathematics, or similar)
• Strong logical and analytical thinking — you enjoy structuring problems and reasoning them through
• Product mindset — you care about the user, the "why," and the end result, not just the technical detail
• Genuine curiosity about using AI tools to build products , and comfort learning new tools quickly
• A positive, reliable attitude and a real willingness to learn
• Fluent English (our working language)

What we offer

• Internship allowance
• A genuine path to a job position for the right person — this internship is designed as a real starting point, not a dead end
• Hands-on experience shaping real products from idea to launch
• A front-row seat in an AI-first, deep-tech startup
• Mentorship, room to grow, and the freedom to take real ownership
• A friendly, supportive team that genuinely invests in your development

Eligibility

Please note that we are not able to provide visa sponsorship or immigration support for this role. To apply, you must already hold the right to live and intern in the Netherlands without sponsorship , and be enrolled at, or a graduate of, a Dutch university . We kindly ask that only candidates who meet these requirements apply, as we are unfortunately unable to consider applications that fall outside them.

Please note

This role is not a pure software-engineering position. We don't build products by writing code ourselves — we use AI tools to do that. If your main interest is hands-on programming, this particular role likely won't be the right fit — but if you're excited about directing AI tools to create products, we'd love to hear from you.

How to apply

We'd be delighted to hear from you. Please apply via LinkedIn by sending your CV along with a short note about why this role interests you . If you've built or experimented with anything using AI tools — however small — we'd love to see it.

We thank everyone in advance for their interest and the time they take to apply, and we look forward to meeting you.
