About the job

At Kantox, we are looking for a talented Software Engineer to grow our testing efforts and help us in the successful delivery of innovative FX solutions. You will be part of Engineering as a quality advocate 🚀

The Kantox Engineering Manifesto

Kantox is a team sport. Our engineering culture is devoid of egos yet we take great pride in our work. We believe in constructively challenging each other pushing our knowledge, code and processes to the absolute limit.

Our processes are based around continual self-improvement, continuous code integration and deployment.

About The Team

Although the whole Tech Department is responsible for the quality and reliability of the platform, from the QA Team we aim to make our contributions at different stages of the development. For example, we help Product Owners to produce product requirements that can lead to a meaningful feature. We also assist developers to write thorough automatic tests to cover all possible scenarios. Additionally, we can write tests and run E2E and integration tests while constantly keeping an eye on details.

Your mission within Kantox

  • Collaborate with Product and Development teams to clarify feature requirements/user stories before development begins
  • Work closely with Developers to ensure requirements/user stories have adequate automated test coverage (back-end, frontend and API)
  • Carry out exploratory testing to uncover hard to find bugs not discovered by automated tests
  • Brainstorm and communicate test ideas, identify quality risks and help the team become better at testing
  • Mentor other engineers on good test practices and methodologies.

Who you are

  • You are creative and passionate about testing
  • You are both technical and product-oriented
  • You are eager to learn, develop skills and knowledge
  • You have a solid understanding of object-oriented programming and clean code practices
  • You have experience in one or more programming languages. We use Ruby, Elixir and Java.
  • You can use the Unix command line
  • You have experience in automation frameworks (RSpec, TestNG, Selenium, Webdriver, Capybara)
  • You are capable of writing tests yourself
  • You are familiar with version control systems (Git and Github)
  • You have excellent communication, organization and interpersonal skills
  • You have a Bachelor's or Master’s degree on Computer Science or related field
  • You have at least 2 years experience as QA or Software Engineer
  • You are fluent in English
  • Permission to work within the EU is a must

It would be great, but not required, if you have:

  • Experience in the financial industry (Fintech)
  • Hands-on experience with virtualization and infrastructure tools (Docker, Kubernetes, Ansible, AWS) and Continuous Integration infrastructure (Jenkins or similar)
  • You also speak some other language (Spanish or French)

  • An environment of innovation, accountability, and constructive feedback
  • A diverse and multicultural team of over 40 different nationalities
  • Grow your role and build your career with our learning and development opportunities.
  • A collaborative and inclusive culture of sharing and teamwork. Build connections for life.
  • Hybrid working and flexible hours so you can work when and where you feel best
  • Some testimonials: “The culture and the people at Kantox make me want to recommend Kantox as a place to work. There is a good balance between learning and growing and support from fellow team members. I feel like the people are very welcoming and make Kantox an easy place to feel at home."
