Big data developer
Piwik PRO Marketing Suite

Piwik PRO is a product that was founded by the AdTech & MarTech experts who develop custom applications for customers under the Clearcode brand. We provide advanced solutions for marketers—web analytics, content personalization for web and mobile, data management and retargeting— tailored to the individual needs of enterprise clients.

We develop and maintain infrastructure able to handle up to 1000 requests per second, process terabytes of data, and ensure the high availability of services. Our team adjusts the tools and technologies to the actual problems we meet during our daily operations. Our main products are deployed both on-premises (self-hosted, PaaS) and in the cloud (SaaS). Each adheres to the strictest privacy and security regulations while ensuring our clients full data ownership. We’re a trusted partner for governments and enterprises operating in industries where data security is fundamental. Our customers include The European Commision, The Government of Canada as well as global financial and telco corporations.

About our work:

  • We work on a product called Piwik PRO Marketing Suite, mostly developing its core functionality – the Web Analytics module
  • In our day-to-day work we face challenges like scaling trackers and recording data in a way that makes it accessible and ready for fast aggregation and filtering; we want to be able to generate reports based on huge data sets
  • Working on the application, we focus on its performance, scalability, and of course we create new features – that’s why we spend a lot of time on research
  • Everything we do – from the process (Agile), to research, specification, implementation, and deployment – is carried out by our team; we have full control from A to Z over the decisions being made

A few tidbits:

  • More than 20 GB data growth daily
  • Data center including at least 8 machines
  • Over 15 million hits in one location on a daily basis
  • Databases weighing in at more than 4TB
  • Microservices architecture (Docker, Rancher)
  • High availability and load balancing are our daily bread


This project is a never-ending challenge. We started as a 4-person team, now it’s 10. We have the green light to expand and in the near future, to create 2 independent teams. This expansion is the fruit of the success of our platform and of our desire to develop it further. We already know that we will work on:

  • New features of the web analytics module
  • Improving the integration of our products (Web Analytics, Tag Management, and others)
  • Scalability (+100M req/day)
  • Stability (development of existing infrastructure)

Who we are looking for:

If you have experience in building similar applications or if you think you have skills and knowledge that could be useful to us, drop us a line. We will schedule an informal meeting with the team to talk about our common vision. At first we didn’t want to put down a list of requirements – after all, help can come from various places. But we do think that the following would be good:

  • a few years of commercial experience with IT projects
  • very good knowledge of popular programming languages (preferably PHP and JavaScript)
  • experience working with huge databases (SQL or NoSQL)
  • an impeccable command of English

Yet these are all skills that can be improved with time. During the recruitment process we will place an emphasis on cultural fit with the team. If we like each other, we will inspire one another.

We can promise you:

  • Flexible cooperation
  • An attractive salary (9000-12500 PLN net on a VAT invoiced B2B contract)
  • A development tools package with a regularly updated resource library, regular events with lectures given by our colleagues, knowledge-sharing (tech and business) groups
  • Private healthcare
  • A Multisport Card
  • A lunch Card
  • Unforgettable parties and integration trips
  • A completely unique work atmosphere – we really like to keep things informal

Please don’t forget to include the following statement in your CV: “I hereby give consent for my personal data to be processed for the purposes of recruitment, in accordance with the Personal Data Protection Act dated 29.08.1997 (uniform text: Journal of Laws of the Republic of Poland 2002 No 101, item 926 with further amendments)”

About Team

Kuba Bomba - Product Manager

How do we work?

We develop an original product, a marketing stack called Piwik PRO Marketing Suite. We follow agile methodologies, especially SCRUM and Kanban, but we are always striving to improve our workflow. During our two-weeks sprints, we deploy to the test environment on a daily basis in order to later deploy stable versions to the production environment. To organize our work, we use the Atlassian stack – JIRA to manage the tasks and Confluence to help us create and maintain documentation. For code versioning, we use the distributed version control system Git, within GitHub. When developing software, we use the Continuous Integration methodology. We are enthusiastic about microservices architectures and we are gradually rewriting the whole application according to that approach. We put an emphasis on process automation, especially for code testing. We use Travis on a daily basis. Additionally, every pull request is subject to closer look, which we conduct in the form of a peer code review.

What makes us special?

Everyone has real influence on the vision of the project and its development direction; we have a flat organizational structure. We take every team member’s opinion into consideration as to to the structure of the organization and choosing technologies. The relationships in the team are informal and friendly, at the office as well as after work. We meet up to play board games, Quake, football, and console classics.

We welcome people who:

  • Are able to effectively manage their own time
  • Have a willingness to develop themselves and expand their comfort zone
  • Want to have a real impact on the development of the product
  • Communicative and with a great sense of humor
