Syska Hennessy – Why Work For Us?

Creating Exceptional Environments

Syska Hennessy Group is the leading global, full-service MEP, information and communication technology (ICT) and commissioning engineer for the government and commercial sectors. With more than 500 professionals across 16 offices, we provide a full range of engineering services for projects of every size and budget: from global headquarters to small office renovations; from the premier healthcare facilities to essential mission critical facilities.

We’ve been at the forefront of innovation since the firm was founded by John Hennessy and Adolf Syska in 1928 to design complex, mechanical and electrical systems at the heart of iconic structures. Whether it’s GSA’s super-efficient Los Angeles Federal Courthouse in Los Angeles or one of the world’s tallest mixed-use structures, Lotte World Tower, in Seoul, South Korea, we are the preferred partner for clients who want to create exceptional, smart and sustainable high-performing buildings.

We are excited about the future. Our energy and simulation modeling enable clients to predict design implications across entire project life cycles and pursue carbon neutral buildings. By integrating essential systems—lighting, power, audiovisual, security, wireless and the core network—we are designing smarter buildings to improve the quality of the environment for occupants as well as reduce operating costs and environmental impact. We’re adept at design-build and alternate delivery solutions, including P3 and lean construction.

Above all, we build long-term relationships with our clients—some of whom we have partnered with for more than five decades—and attract the industry’s best talent through a learning, diverse and collaborative culture.

We are Syska.

Why Join Syska?

In 1928, two young engineers came together, combining their abilities and aspirations to create a collaborative environment that would lay the foundation for the Syska Hennessy Group.

Since that time, Syska has been at the forefront of the industry, shaping the mechanical and electrical systems of the 21st century. Employees embrace ownership of each project, bringing quality, innovation and integrity into each client relationship.

Nurturing the above core values has made Syska one of world’s leading engineering firms with more than 500 professionals across 16 offices. This coupled with the diversification of Syska’s services into both consulting and technology truly provides a unique place to cultivate your career and future.

The key to Syska’s continued success is its commitment to investing in talent. This means attracting high caliber employees for engineering and corporate roles, fostering their success through continuous learning, mentoring and providing the tools to work seamlessly. Team members are dedicated to supporting both clients and colleagues. Syska is a place where you can build an exceptional career and have a lasting impact on the world.

Giving back is a part of the Syska DNA. We continuously support employee participation in important community causes, help design public schools in impoverished areas of the world and develop high schoolers into future industry leaders through initiatives like the Architecture-Construction-Engineering (ACE) Mentor Program.

Syska is a collaborative environment where exceptional is at the forefront of everything we do. We are committed to being the best, to advancing engineering design practices, all while supporting our clients with integrity. To make all of that happen, we rely on the talent, drive, enthusiasm and the total job satisfaction of the great people who work here.

    I have been working at Syska Hennessy full-time


    The company is evolving to keep up with market trends. Through continuous improvements coupled with the company's strong brand, the current dynamic is exciting advocating those that have an entrepreneurial spirit.


    The only con that I see is that we need more of the work to be spread out amongst other team members. I can understand that the better employees are trusted to do a great job but management needs to look at opportunities on how to alleviate some of the time consuming tasks of the more busy team members. There are team members that are not as busy that can potentially help.

    Advice to Management

    Keep challenging the status quo and holding everyone accountable.

    I applied online. The process took 2+ months. I interviewed at Syska Hennessy.


    Interviewed in front of a panel which was very attentative and personable. The interview was very natural and flowed freely from both sides of the table. Interview was more geared towards familiarity and personal fit with the company rather than hoops to jump through.
