Day-to-day duties will include:

  • Utilizing the newest web technologies to code and test software.
  • Participating in designing and building game-changing features.
  • Integrating our application with 3rd-party services.
  • Maintaining, improving and modernizing the existing code base and infrastructure.

Knowledge of the following will be considered a plus:

This is a remote opportunity, but you are also welcome at our Helsinki office. Either way we expect you to be available for the majority of the Finnish working day (9-5 GMT+2), and that you can be directly employed by a Finnish company. Capability for team work, a proactive attitude and in general being a “good fit” is important. Communication skills, english fluency and a willingness to participate in discussions, remotely or not, is required. An understanding of Finnish is a definite plus.

We may be a small team, but we are working together. As we are a startup you may be expected to help where you can with a variety of stuff that needs doing from time to time, just like the rest of us. (Website, demos, testing, customer support, marketing or its automation etc.)

At Seidat, we trust our employees. We want everyone to have room to grow in the direction they want, as long as they are willing to put in the work. In our mostly flat hierarchy advancement is achieved through deeds, not years. Every Seidat employee is involved in serving customers regardless of position. We have an office in the center of Helsinki and we offer equipment as needed, competitive pay and permanent employment.

As part of your application we would like to see your resume, examples of relevant projects that you have directly contributed to (including code), as well as a cover letter of why you want to work with us.

We look forward to your application!
