Senior Fullstack Developer with Product Mindset // Small Improvements

Small Improvements Full Time Berlin, Germany 1 week ago
We’re looking for a Developer with 6+ years of experience building complex products. Projects range from small to large across the whole stack (Java, TypeScript, React, CSS).

This is a “remote-first hybrid position” based in Berlin: You can work remotely a lot, but should be based in Berlin or nearby. It’s a full-time position,  after the first 3 months we can also offer a 32h week. The salary range is between €70k and €100k depending on experience, plus 3k€ annual training budget and other smaller perks.



<strong>About us</strong>

We’re a tight-knit company based in Berlin, with remote staff in the UK and the US. We’re building an employee feedback & performance solution for medium-sized companies worldwide.

Small Improvements helps people give and receive feedback, so they can learn from it and improve. At the same time our customers benefit from lower attrition and more motivated staff, so it’s a win-win situation.

<strong>What you'll do</strong>

Our development team consists of seven permanent developers that are aided by freelancers occasionally. You will join them in improving our core product.

More specifically, you will:
<ul>
<li>Dive into the codebase and improve existing features across the board</li>
<li>Define and develop new features together with the PM-team based on customer feedback, data analysis, and your expertise</li>
<li>Maintain our application by fixing bugs and structural weaknesses and making sure they never reappear</li>
<li>Work with all staff (technical or not) to continuously improve our processes and structures (we value feedback, efficiency and transparency)</li>
<li>Review, test, deploy to staging and production, and ensure overall system stability</li>
<li>Research and learn new tools and libraries along the way, when the need or interest arises</li>
</ul>


<strong>Who we're looking for</strong>

You'll fit in perfectly if this feels like you:
<ul>
<li>You like to get things done, you take ownership,  you can inspire and mentor others, but you're also humble and love to learn from others.</li>
<li>You have advanced knowledge of object-oriented programming and modern frontend development, including the ability to work with CSS.</li>
<li>You're passionate about product work, and have good knowledge of interaction design. No need to be an expert, but your goal when working with PM is to find efficient <em>and</em> usable solutions for our customers.</li>
<li>You're interested in great architecture and clean code. We have a monolithic application and use many ideas from DDD, Clean Architecture, Software Crafts(wo)manship and Functional Programming.</li>
<li>You're keen on using AI where it makes sense, and stop where it gets dangerous.</li>
<li>You're experienced in "remote-first". We do have a lovely office and get together regularly, but we work remotely most of the time. You don't wait for information to come to you, you're actively sharing and learning in Slack, GitHub and Linear.</li>
</ul>
