Our Tools

We constantly use cutting edge technology and at the same time, we endorse experimentation. Our internal monitoring systems make sure all our experiments are performed in isolation so hey, go nuts!

This is an outline of our current tech:

  • Our web app is in ReactJS using Redux and supported by NodeJS
  • Our Back end is in PHP using Yii, Laravel, and Lumen
  • We use ReactNative for our mobile app
  • All our applications are dockerized
  • Our servers work on Kubernetes - the master of the universe!
  • We like microservices. It is our way to move from a legacy monolith to a Services Oriented Architecture and to modernise our stack
  • We like serverless technologies even more
  • We use databases of all sorts to suit our needs: MySQL, Aurora, ElasticSearch, Redis, DynamoDB.
  • Data Science is our way to the future! Our projects run on Java and Python and also consume a number of third party tools!

If you are curious to find out more about our tech stack, keep reading in our blog.


About the role

As a backend engineer, you will contribute to our core application, existing and new microservices, serverless parts of our stack and also interact with a multitude of databases.

Our core application is written in PHP, using the Yii framework and we also have a number of microservices built on the Yii, Laravel, Lumen, Spring Boot and Flask frameworks. We strive to use serverless technologies, ranging from Nodejs lambdas to complicated ETL operations.

Our databases are our horsepower, so you will closely engage with increased data loads on MySQL and Aurora databases while using our ElasticSearch cluster to perform search operations.

The final product is assembled and dockerized by the CircleCI pipeline to deliver the best performance and experience to our users.


Consider these four points to give this role a closer look

  • You will work with creative and open-minded people who are not afraid to listen to your opinion, which will be highly appreciated and valued.
  • You will participate in an agile team and develop features based on our roadmap
  • You will deliver high quality scalable and well-tested code by following our comprehensive coding standards and follow our coding principles.
  • Oh and.. we have a few more services to work with such as Redis, Redshift, DynamoDB, Kinesis, Lambda so as to increase the number of tools available. Cool, right?

Ideally, you’ll

  • Have some experience working in a large scale web application and a good understanding of how the web works
  • Have good knowledge of PHP and you’ll also know how to use Composer
  • Have used at least one popular PHP framework (Yii, Laravel, Lumen etc)

  • Be aware of the most popular/common services provided by AWS

And you’ll

  • Think analytically and methodically with attention to detail
  • Refactor problematic, incomplete parts and constantly improve our codebase
  • Read, understand & debug code
  • Follow coding standards and apply good practices
  • Deliver testable, efficient, reusable, high quality and easy to read code


Bonus points if you

  • Have worked on a serverless environment
  • Are familiar with other databases such as Redshift, PostgreSQL, DynamoDB
  • Have interacted with ElasticSearch or similar search engine (SOLR)
  • Have used MongoDB or other NoSQL database to store application data

  • Are a confident user of debugging & profiling tools like Xdebug



A few of the many perks of joining the PeoplePerHour team:

  • Competitive salary with an annual pay review
  • Private health insurance
  • Flexible work - freelancing is all about flexibility 
  • Days off - We encourage breaks and freshness so we expect you to be with your loved ones on your birthday and name-day! 
  • Unlimited coffee for encouragement!


What should you do next?

If you feel this is the right role for you, please submit your CV.

Next, we set up a phone interview with one of our engineers. This will focus on your technical skills and culture fit.
