&lt;p&gt;&lt;strong&gt;About us&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt;Mix together a bunch of talents (absolutely crazy about what they do) and tell them to reinvent digital marketing. Now, add a healthy dose of corny jokes and love for some out-of-this-world hobbies. Congratulations, you’ve just created Codewise! Except we already did it almost 10 years ago :)&lt;/span&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt;&lt;br&gt;&lt;/span&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt;&lt;br&gt;&lt;/span&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt;We’re a software company based in Cracow, Poland developing cutting-edge marketing technology, like Zeropark - our self-serve performance ad exchange, and Voluum - a cloud-hosted ad measurement &amp;amp; management platform. We’re addicted to helping our clients achieve their goals with our tools!&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt;Pleasant side effects of our work include being named by the Financial Times among the fastest growing companies in Europe. 3 years in a row!&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;About the product and team&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;&lt;a href=&quot;https://zeropark.com/&quot;&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt;Zeropark&lt;/span&gt;&lt;/a&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt; is the key product of Codewise, an ad-tech company based in Kraków, Poland. It allows digital marketers to advertise their products online, and website owners to monetize Internet traffic by displaying ads. &lt;/span&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt;And since we love the challenge, the Zeropark Team has launched its newest venture yet — the &lt;/span&gt;&lt;a href=&quot;https://newprogrammatic.com/&quot;&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt;NewProgrammatic&lt;/span&gt;&lt;/a&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt; search traffic platform (we’re already working with some of the biggest brands in the marketing industry, just visit our website to learn more!).&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt;Working with us you will face many technical challenges and constantly develop your skills. We handle large amounts of traffic (up to 500k requests per second), run on Amazon Web Services (20+ Java-based applications)&lt;/span&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt;, &lt;/span&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt;and are entirely responsible for the whole development cycle: technical design, programming, testing, deployments, and taking care of our production environment.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt;We work in 2 scrum teams, 10 engineers in total — Backend, Frontend, and QA. We cooperate closely with UX designers, Content Writers, Product Owners, and other colleagues from the business side of the project.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt;We’re a mature team that still thrives on its start-up nature — we move fast, we experiment a lot, we’re not afraid to fail, and we learn from mistakes.&lt;/span&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt; The things we value are clean code practices and code reviews, as well as helping each other and sharing knowledge.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Key responsibilities&lt;/strong&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li style=&quot;font-weight: 400;&quot;&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt;Designing, building, testing and maintaining our high-performance software and its AWS infrastructure&lt;/span&gt;&lt;/li&gt;
