Senior PHP Engineer

Brno (CZ) / Full-time / 80,000 - 100,000 Kč per month

With us, you won't be writing another average website or web app – instead, you’ll be designing, building and operating our perpetually-running monitoring engine and suite of surrounding systems. Not only will you have a direct hand in the product, you contribute towards further improving the scalability of a fast growing startup.

Although this vacancy is in English, most of our team speak both English and Czech.

What is ContentKing?

ContentKing is a website monitoring service used by digital marketers around the globe. For customers like Netflix, Shopify, Adidas, and Fedex, we monitor their websites 24/7, keeping track of any changes and alerting them whenever anything goes wrong.

Trusted by 5,000+ digital marketers at companies like:

The Challenges

Being an engineer at ContentKing comes with a multitude of challenges:

  • ContentKing monitors sites with millions of pages and maintains an index with a huge amount of data that is constantly being updated.
  • Being a monitoring service, we have a strong focus on high availability and redundancy to minimize the risk of downtime.
  • We have a constant stream of new trial accounts coming in, and this requires our platform to support rapid scalability.
  • We deal with a vastly versatile data set: the web is very unstructured and comes with many challenges.

We are seeking someone to take on these battles with us.

Our Culture

If you're looking for a job where you get specs and then mindlessly jam out code, this won't be it.

We’re a small team, so working at ContentKing means contributing to the product on a conceptual level as much as contributing to the codebase.

That’s why every team member takes a lot of ownership, and we have a culture that's all about transparency and data sharing:

  • Want to know what features customers are requesting?
    → Check feedback and feature requests on Productboard.
  • Interested in seeing what users are reporting to Support?
    → Check Intercom or the #support channel on Slack.
  • Eager to know our business metrics, such as revenue?
    → Check Geckoboard on any of the screens in the office.
  • Have ideas how to improve the product or our processes?
    → Share them, and you'll likely see them get implemented.

Being an engineer at ContentKing means being part of a tightly knit team of people passionate about product.

Our Craft

Our codebase is our crown jewel, and we take great care of it.

That's why we value:

  • Independent modular architecture,
  • Continuous refactoring to keep the code ready for changes (and simply a pleasure to work with), and
  • Iterative revisiting and polishing rather than rewrites.

Updates to our monitoring engine get released daily, while it runs 24/7 as an orchestra of connected subsystems.

On top of industry standards like Sentry and ELK, we invest in our own diagnostic tooling and measurements. The ability to monitor systems’ performance on dedicated Grafana dashboards has proven invaluable to us.

We develop in swift cycles – not only to quickly respond to customer feedback, but also to continuously reflect on our processes and priorities. We employ PhpStan and a suite of automated tests to cover our back. We read and review each other’s code both on GitHub and on-screen.

Project sponsorship

ContentKing is proud to sponsor the Nette PHP Framework and PHPStan projects.


We are looking for colleagues who feel comfortable challenged by the above description and meet the following requirements:

  • Have 3+ years of experience with PHP,
  • Have 3+ years of experience with SQL,
  • Be familiar with modern design patterns,
  • Have the ability to clearly reason arguments, and
  • Be able to communicate in English.

Having experience with any of the following is a bonus:

  • Go
  • Elasticsearch
  • Graph databases
  • PHP in CLI
  • GraphQL
  • Message queues (RabbitMQ, Kafka)
  • Application architecture design

Our Interview Process

The interview process consists of three steps:

  1. First interview, meeting our PHP engineers
    The purpose of this meeting is to get to know each other’s backgrounds and experience. We share our challenges and ways of working, and would love to get your thoughts on that.
