ACCIONA is a global company, leading in the development of regenerative infrastructure that creates a positive impact on society. Our workforce consists of more than 65,000 professionals, present in more than 40 countries across the five continents, all contributing in our mission to design a better planet. We have successfully delivered large infrastructure projects across Canada since 2001. The Senior HR Business Partner is a hands-on, high-impact role supporting ACCIONA’s Canadian operations. Created as a result of the company’s continued growth and strong project portfolio, this role reflects the evolving needs of our business and people. Operating in a fast-paced environment, the role requires the ability to manage competing priorities, work across multiple stakeholders, and deliver practical HR solutions. It combines HR partnership with a strong operational focus, requiring a hands-on approach to execution across a wide range of activities. The role partners with employees, managers, leadership, and HR colleagues, contributing to HR operations, talent initiatives, and the execution of ACCIONA’s people strategy. Working closely with the Talent Operations Director, it plays a key role in keeping things moving day-to-day, taking the lead on initiatives, and working side by side to make sure priorities are delivered. This is an opportunity for someone adaptable and solutions-oriented, who is comfortable navigating both operational and more complex HR matters. The role offers broad exposure and the opportunity to take on increasing ownership as ACCIONA continues to grow. The role is based in-office in Mississauga, close to the airport, with periodic presence required at project sites across the GTA and occasional travel within Canada, with some flexibility for broader travel if required. This is a new position within the Mississauga office.
