Job description

Omni Calculator is looking for a part-time researcher and content writer with expertise in one of the following fields: physics, mathematics, finance, or "general science" (topics that don't belong to a specific category but require critical thinking).

As a researcher at Omni, you will be responsible for creating calculators from idea until the final product. You will choose your topic, research it, and propose the most optimal tool that helps our users. 

  • Researching problems in your area of expertise (online sources, scientific articles)

  • Building calculators for these problems (the building process is fairly easy to learn)

  • Choosing keywords to optimize your text around

  • Writing high-quality texts for various target groups 

  • Participating in ongoing projects, e.g. cooperating with the marketing team in creating calculators about recent newsworthy topics


  • A certain degree of expertise in your area (physics, mathematics, finance, or science in general).

  • Excellent written English skills (C1 level, we don't need the actual certificate).

  • An ability to write engaging texts for both laymen and advanced readers in your area of expertise.

  • Good self-organization and time management skills. 

  • An ability to commit to at least 16 hours of work per week.

Nice to have (but not required)

  • Content writing and SEO experience.

  • Experience in popularizing science, teaching, etc.

  • Unique interests that can be turned into calculators :D


  • Flexible working schedule and ability to work fully remotely.

  • A beautiful office in the old town of Kraków (Karmelicka 14/7, Kraków).

  • A multisport card (if you’re in Poland).

 Salary & Employment

  • The base salary is 3-3.3k net PLN, depending on the type of contract. This amount is for a full-time engagement (168 h per month), proportionally less if you work part-time.

Research and writing skills

Your role at Omni Calculator will be writing calculators and an accompanying text.

Please choose two out of the nine questions listed below and write a few paragraphs (between 200-300 words) explaining these topics. You can expand the field by holding and dragging the bottom right corner. 

Most often the answers will require some research - consulting online sources is perfectly acceptable (and even expected). However, please do not ask anyone else to correct your English. Try to find a balance between simple and technical language. Focus on explaining your reasoning and any formulas you introduce.
