ITDS is a Polish technology consulting and staffing firm that supplies engineers, analysts and project specialists to banks, insurers and other financial institutions. Its consultants work inside client delivery teams on software development, testing, business analysis, data engineering, cloud infrastructure and cybersecurity, usually on long-running programmes rather than short advisory engagements. The firm is based in Warsaw, recruits across Poland and increasingly for remote assignments elsewhere in Europe, and posts a high volume of contract and permanent technology vacancies under its own name on behalf of client employers.
