Building and Sustaining the Global Nuclear Workforce

About our history

Thomas Thor was founded in 2009 by three individuals that realised the need for an organisation dedicated to building and sustaining the global nuclear workforce. The nuclear energy industry is truly global and has been built on strong foundations of international cooperation over many decades. Our role is to support organisations in the nuclear industry in finding the professionals they need to succeed. As well as being extremely well connected within the global community of nuclear professionals, we also have a long and successful track record of bringing professionals from other industries and major projects to the nuclear industry. We act to increase diversity within the nuclear workforce in terms of gender, ethnicity, nationality and industry background, and our commitment to diversity is reflected in our own team.

Since 2009 we have grown from a single office in Amsterdam to an organisation with a truly global footprint and eight offices across Europe, North America and the Middle East. There are 60 of us delivering our core services in recruitment, executive search and HR consulting across the world. We strongly believe in well-being, and actively promote and facilitate initiatives to promote health, happiness and well-being within our organisation. I speak for our whole team when I say that we are proud to be working towards a clean energy future.
