Principal Mechanical Engineer – India

As a Principal Engineer –Mechanical at Black & White Engineering, you’ll lead the mechanical design of complex critical buildings and infrastructure projects. You’ll work with a high-calibre global team delivering work that reflects the highest, innovative standards in the industry.

What’s in it for you

Take real ownership of complex projects

You’ll work with a high degree of autonomy — leading mechanical design from concept through to delivery, making technical decisions, managing budgets and driving projects forward. This isn’t a role where you wait to be told what to do. You’ll own your projects and be trusted to deliver them.
Work on some of the most technically demanding projects in the industry
Data centre design experience is central to this role, and for good reason. The mechanical engineering challenges involved in critical buildings and infrastructure are among the most complex in our sector — requiring genuine technical depth, precise coordination and the ability to think well beyond the immediate task.

Influence across a global business

Reporting to the Associate Director, you’ll collaborate with local and global teams, represent Black & White externally and contribute to the technical direction of the business. The One Global Team approach means your expertise won’t sit within one office — it will reach across the organisation.

Develop the team around you

Leadership at this level means more than technical delivery. You’ll mentor and coach engineers across the team, oversee performance and development, and play an active role in building the next generation of mechanical engineering talent at Black & White.

A business that is rapidly growing

With over 500% growth since 2020 and ambitious plans that show no sign of slowing, there is real opportunity here for the right person to grow alongside the business into broader leadership, wider geographic scope or deeper technical specialism.

Essential skills
