Senior Software Engineer (Back-End)

  • By Karolina Dabek
  • 12 October 2021

Back-end engineers enjoy all the pros and cons of distributed programming. The Company ship changes to production multiple times a day andthey delivery pipeline makes your code ready to join thousands of already running containers in just 5 minutes. The Company services land on Kubernetes that is hosted on AWS. They also leverage the power of AWS serverless like Lambdas, DynamoDB, AppSync, Cognito, just to name a few. Services communicate either via messaging or good old HTTP. The Company platform is defined entirely as code (Terraform, Ansible) and they get lots of goodies out of the box – alerting, logging and telemetry to name a few. They are believers in the DevOps culture, but they still have some things to do to get there.


Our Client are looking for engineers who are ready to tackle complex challenges with the right tools. They don’t expect our future colleagues to have the experience with every language or tool we use at production. They write mainly in Go and Python but, as everything in life, these can be learned and they are sure that our bootcamp will get you up to speed. We are also a team of engineers with diverse backgrounds and we are more than happy to learn from your experience too.


The new engineer will join one of the company product teams:

  • Tutoring team which gives students an option to connect with an expert within a few seconds.
  • Textbook Solutions team, working on the latest product from the company which allows students to access millions of top-quality educational solutions from thousands of textbooks across the globe.

And will be responsible for:

  • Designing, developing, and maintaining code for the company platform to enhance the great learning experience for our users.
  • Solving complex challenges such as performance, scalability, and security
  • Collaborating with other software engineers to design scalable services, plan feature roll-out, and ensure high reliability and performance of your deliverables.
  • Conducting code reviews, contributing high-quality documentation, and building robust test suites for your features


  • 5+ years of experience writing web services in a general-purpose programming language
  • Experience with databases/data stores
  • Interest in TDD and specific experiences using a test heavy approach to solve problems and create solutions
  • Ability to brainstorm and co-create new solutions, both business and technical
  • Familiarity with a complex, high-performance platform
  • Established ability to diagnose technical problems, debug complex problems across the whole stack, and automate routine tasks
  • Focus on the needs of our users, both internal and external
  • Understanding of core testing principles
  • High level of self-organization and ability to make your own decisions
  • Great communications skills and ability to learn fast


  • Knowledge of Go or Python
  • Experience building distributed systems at scale
  • Experience building microservices
  • Experience working with public cloud provider offerings (AWS, GCP, Azure, etc)
  • Knowledge of Deep Learning techniques and frameworks
  • Statistics/Data Science experience
  • Experience working with messaging queues and/or streaming platforms
  • Experience working with GraphQL
  • Experience working with NoSQL databases


  • Location: Kraków or Barcelona, or remotely from Poland/Spain
  • Salary: 15 000 – 23 000 PLN gross/monthly
  • Start date: as soon as possible (however, we’re happy to wait for the right person)
  • Some of our benefits – the final offer will depend on the location:
    • Flexible working hours and the possibility to work remotely
    • Personal development budget 800$ per year +  unlimited time off policy for participation in conferences and workshops and access to an online learning platform with courses from Udemy, Harvard Manage Mentor and many others
