Informacje o stanowisku

Sigma IT Poland is a division within NEXER GROUP – a custom software development company. In Poland, we started in 2017 and are now 180+ crew with an office in Wrocław, Warsaw, and Cracow. We have the opportunity to work with world-renowned brands from Scandinavia, the UK, and Western Europe. Our goal is to grow stronger, rather in competencies than in pure numbers.

Would you like to join projects that are developing in modern technologies and with supportive team? You are in the right place

We are looking for an experienced Fullstack Developer with the ability to work primarily with the frontend rather than the backed. The ideal candidate will have a strong foundation in frontend development, with skills in C#, .NET 6+, React, TypeScript, and a solid hands-on understanding of CI/CD workflows. Experience with additional tools and technologies such as Storybook, Cypress, AWS, and GitLab CI/CD workflows is highly desirable. Fluent English is a must.

You will be part of a 50-person team divided into several smaller agile sub-teams. The main goal of the project is to replace an old contract management system with a modern web-based solution to simplify the management of a large number of contracts from different markets.

It will be implemented for the Swedish company in the automotive sector and will be developed using new backend technologies such as .NET and AWS, together with the React frontend. Emphasis is placed on code quality and testing, which contributes positively to the project. 

Regular technical and architectural meetings are held, allowing team members to propose solutions and actively participate in discussions. Solutions are not imposed from the top; every suggestion is considered, fostering a collaborative development environment.

By joining us, you gain the following:

  • Exciting projects, a multinational and inspiring environment for talented IT professionals. Various projects in diverse, cutting-edge industries. Biotech, Automotive, Internet of Things, or AR/VR;
  • Code review done by skilled engineers (over 60% of our team are people with over 5 years of experience in the industry);
  • Becoming part of a team of motivated individuals is here to stay. We value loyalty – as you grow, we grow with you;
  • Respect for your private life so you dont have to work overtime or on weekends;
  • Online and offline integration events - including remote X-mass party and annual WOW tour trip abroad - so far weve been in Cape Town and Barcelona.

Perks and benefits:

  • Fully remote work from your convenience or in our office in Wrocław, Warsaw or Cracow;
  • Choice of employment form: we offer B2B or employment contract;
  • Free benefits such as Luxmed, Multisport, and life insurance in Nationale Nederlanden;
  • Attractive referral system (9,5k for senior, 6k for mid, 2,5k for junior);
  • Personal Training Budget and Passion Day - an extra day off for your passion, hobby, and growth to spend as you please;
  • Flexible working hours with no micro-management approach. Our core hours are 9-15, the rest of the working time is your decision;
  • We provide high-quality work equipment + 2 additional monitors and accessories.

If you apply for this position and match our expectations, then:

1) You will be invited to an online meeting with the Recruiter to learn more about the project and ensure that we meet your expectations.

2) You will participate in an online technical review meeting.

3) You will have an online meeting with our client.
