 Every customer interaction with Together relies on the systems we build. Whether it's a researcher accessing their models, an enterprise team collaborating on a shared project, or a developer making an API call, we make authentication seamless and invisible for simple cases while providing robust, enterprise-grade capabilities for complex organizational structures. Our work directly enables Together's growth from individual users to large enterprise teams, and we're actively building the next generation of collaboration features that will unlock new ways for customers to work together securely and efficiently across all Together products.

 Location: Hybrid in Amsterdam, NL or remote UK, Ireland &amp; Germany
 </li>
 <li>
 Full-time: This means 40 flexible hours, Monday through Friday.
 
 
 </li>
 </ul>
 You'll own well-defined features and small projects end-to-end, shipping work that lands in front of customers. You'll get guidance as you take on unfamiliar problem spaces, with plenty of room to grow toward more autonomy over time. We pair, review each other's code, and learn in the open &mdash; it's a strong environment to level up in.
 
 
 
 Responsibilities
 
 
 
 <ul>
 <li>
 Build and ship features across the stack &mdash; TypeScript/Next.js on the frontend and Elixir/Phoenix services on the backend (which you can grow into)
 </li>
 <li>
 Own well-defined pieces of work end-to-end, from implementation through testing and rollout
 </li>
 <li>
 Contribute to our identity and access features: SSO, OAuth, organizations, projects, API keys, and role-based access control
 </li>
 <li>
 Learn the Elixir/Erlang VM (BEAM) and how we run it in production
 </li>
 <li>
 Participate meaningfully in code review and build your familiarity with our testing, tooling, and workflow
 </li>
 <li>
 Surface blockers early and collaborate with the team to work through them
 </li>
 <li>
 Work with relational (PostgreSQL) and non-relational (MongoDB) data
 
 
 </li>
 </ul>
 
 Requirements
 
 
 
 <ul>
 <li>
 Around 2&ndash;3 years of professional experience writing and shipping production code
 </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>
 <li>
 Writes clean, well-organized, well-tested code, and treats code review as a way the team grows together
 </li>
 <li>
 Comfortable owning scoped work and surfacing blockers early
 </li>
 <li>
 Curious, open to feedback, and willing to propose new approaches and make mistakes
 
 
 </li>
 </ul>
 
 Nice to Have
 
 
 
 <ul>
 <li>
 Interest in, or some exposure to, identity and access concepts &mdash; authentication, authorization, SSO, OAuth (this is a great team to learn them on)
 </li>
 <li>
 Any exposure to functional programming (Elixir, Erlang, or similar)
 
 
 </li>
 </ul>
 If you don't meet 100% of the above, you should still consider applying. It's completely fine if you haven't used Elixir yet &mdash; if you're excited to learn it and have a passion for this kind of work, we want to talk to you.

Software Engineer Backend

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>
