Seenons bv

<div><h2 class="jobSectionHeader">Your launchpad to a career with impact</h2> 
Seenons is a tech company on a mission: a world without waste. As a certified B Corp, we&rsquo;re building the digital logistics infrastructure that enables organizations to separate, track, and route waste to its next best use, turning a fragmented, outdated system into one that&rsquo;s circular and future-proof. 
Our international platform brings together all players in the waste industry for circular waste management. We help large organizations reduce waste and save valuable resources from going to waste. We are currently active in four European countries and are planning to expand. As of now we are looking for a Software Engineer Intern (internally we use the title Product Engineer Intern) to join our Tech team.<h3 class="jobSectionHeader">
About the role</h3>
You'll join our engineering team of 8, working across our internal Cockpit and three customer-facing apps (Waste Saver, Data, Partner Portal). We work as one team, broken into smaller monthly projects - so you'll get to touch most of the platform during your time with us.
What you&rsquo;ll be doing:<ul><li>
Ship features end-to-end across the stack (frontend, backend, a bit of data, a bit of infra - whatever the problem needs)</li><li>
Use AI tooling (Claude, agents, and more) as a core part of how you build</li><li>
Talk to the people who'll use what you build, whether that's our internal business users or our customers out in the world</li><li>
Contribute to our internal libraries, patterns and the way we work</li></ul><h3 class="jobSectionHeader">
We&rsquo;d like to hear from you, if you</h3><ul><li>
Are AI-native: you've already built things with LLMs, you know what they're good at and (more importantly) what they're not, and you're allergic to &quot;but AI said so&quot; as a defense.</li><li>
Are eager to take ownership and have proved it with school projects, side projects, internships, or something you can show us.</li><li>
Have some experience with TypeScript, JavaScript or Python - ideally with a frontend framework (we use Vue), a backend one (we use NestJS), or both. Want to contribute full stack, even if you don't know all parts of it yet.</li><li>
Are pragmatic - you'd rather ship a useful 80% than polish a 100% that nobody asked for.</li><li>
You ask &quot;why are we doing this?&quot; and &quot;have we talked to a user?&quot; before reaching for the keyboard.</li><li>
Thrive in a dynamic environment where collaborating with a product manager, designer, engineers and end-users is part of the job.</li><li>
Study in the Netherlands and would like to work from the office at least three days a week.
</li></ul>Ah, one more thing...
If you&rsquo;re not entirely sure whether you meet all the requirements, but you&rsquo;re enthusiastic about us and the role, apply anyway! We want people who are also willing to take risks. Together we learn and grow.<h3 class="jobSectionHeader"> 
What you get with us</h3><ul><li>
Drive impact in the pursuit of a zero-waste future.</li><li>
Learn by doing alongside engineers who'll review your PRs properly.</li><li>
Join a supportive, collaborative team of 80+ international colleagues in a thriving scaleup.</li><li>
Work from our Amsterdam Houthavens office with a panorama harbor view, close to Amsterdam CS and Sloterdijk - with commuting costs reimbursed.</li><li>
Join fun events and office drinks to celebrate successes.</li></ul><h3 class="jobSectionHeader">
Done wasting?</h3>
Great, so are we. Tell us why this role excites you and how you&rsquo;d use your skills to help us grow. No long cover letter needed, just thoughtful input in our application form will do. Apply now, and let&rsquo;s build a waste-free future together.</div>

WHO WE ARE
We&rsquo;re Elements, a digital agency with almost 30 years of experience building mission-critical mobile apps for leading companies. But we don&rsquo;t just write code, we create an environment where technology, people, and processes merge to deliver measurable business value. We have evolved beyond traditional development. Our approach is to combine strong and deep rooted Software Engineering principles with advanced AI powered workflows using the latest tooling and AI models to solve complex business challenges. We build faster, smarter, and with higher quality.

You have genuine curiosity for your field, staying up to speed with the latest innovations and sharing knowledge with colleagues.
With our increasing focus on mobile applications, both for our existing and greenfield projects, you will have the exciting opportunity to apply your skills across a range of innovative applications.
In an industry that never stands still, and even less in the era of AI, we embrace the evolution of technology as an opportunity rather than a blocker. You will have the space to explore and master diverse tech stacks, ensuring our solutions remain cutting edge. Whether it's adopting a new framework or exploring a new language, your willingness to learn and adapt is what will drive both our projects and your career forward.

Your tech skills and experience:<ul><li>
4-5 years of professional experience with React Native, including hands-on project work</li><li>

 Solid full-stack or backend engineering, especially with TypeScript (backend and/or frontend, for example with Next.js) &mdash; or another modern stack whose ideas you can bring across
 </li>
 <li>
 Genuine enthusiasm to learn Elixir and Phoenix &mdash; production experience isn't required, and we'll support you in getting there

 <li>
 Writes clean, well-organized, well-tested code, and treats code review as a way the team grows together
