Principal Civil/Structural Engineer-Hybrid

About the opportunity:

The Civil/Structural team specialises in solving the most complex and technically demanding structural engineering problems.

Each project is unique, but typically involves consideration of dynamic load effects due to extreme hazards, including seismic, blast, and impact. We have to look beyond code checks to get a deeper insight into structural response and failure mechanisms, considering ductility, nonlinear buckling, and soil structure interaction.

We work things out as a team, starting from first principles, researching methodologies, challenging assumptions, thinking outside the box, and constantly learning.

We work to the highest standards. Our complex analysis models are rigorously validated. Everything we do has to be fully evidenced and justified through independent third party review and ultimately to the nuclear safety Regulators. As a result, this is one of the most varied and challenging roles you can take on as a civil/structural engineer. The main locations will be based around Winnersh or Glasgow. However other UK office locations considered. Responsibilities will Include:
