dirk1Lights, lumens and leadership: This is Dirk Fieberg’s career in a nutshell.

Dirk’s career in engineering began in the defense industry, where he worked on command and control systems. Transferring that electrical expertise to the lighting industry, he has spent more than two decades focused on lighting in a wide array of applications, from architectural illumination to industrial and commercial lighting to now underwater applications.

Although an engineer by trade, Dirk has a mind for business. Throughout his career, he has taken on increasing levels of business management, effectively managing people, projects, finances and new business development. Not only has his leadership helped his direct reports thrive in their roles and careers, but his volunteer mentorship of a children’s center helped guide the school through business challenges to success.

In 2016, Dirk’s engineering and business proficiency led him to co-found Arctic Rays, specializing not only in deep-sea lighting but also imaging devices, surveillance and asset tracking systems and more.

Dirk earned his master’s degree in engineering management and his bachelor’s degree in computer engineering, both from Florida Tech in Melbourne, Florida. He holds six patents and is trilingual, fluent in English, German and Spanish.

He lives in Indialantic, Florida with his wife, two children and dog. When he is not at work, he can usually be found at a theme park or working on projects in his home.


lee1Lee Frey is a leading subsea engineer, innovator and deep-sea explorer. He has spent over two decades developing novel technologies to enable ocean research and exploration. Lee also has extensive field experience, logging over 1,000 hours as a manned-submersible pilot and leading over 50 seafaring expeditions all around the world.

A Philadelphia native, Lee developed his love for the oceans at an early age, spending time along the southern New Jersey shore. At university, he combined his fascination with science with his passion for the water, obtaining bachelor’s and master’s degrees in ocean engineering from Florida Institute of Technology.

Over the course of his career, he has held engineering, operations and leadership positions in various organizations such as the Woods Hole Oceanographic Institution, Harbor Branch Oceanographic Institution, Australian Oceanographic Foundation, OceanX and others.

In 2015, Lee’s entrepreneurial drive and extensive experience in design and deployment of underwater vehicles and optics led him to partner with his longtime colleague, Dirk Fieberg. Together, they founded Arctic Rays, a small, energetic, high-tech start-up company based on Florida’s Space Coast that designs and manufactures cutting-edge underwater lighting and imaging systems. Lee lives with his family in Melbourne Beach, Florida.

mat1An aptitude for electrical engineering and a passion for the ocean have converged in Mat Jordan’s career in deep-sea technology design. After a short time in special projects for military and defense instrumentation design, Mat found his calling in the ocean as an ocean engineer.

He has designed life-critical electrical systems for manned submersibles, going on test dives both as passenger and as pilot, before moving into engineering management and production management over the electrical team. Mat designed the landers for the Triton Hadal Exploration System and was part of the team that designed and built The Limiting Factor, the world’s deepest-diving submersible.

Now the senior electrical engineer for Arctic Rays, subsea technology manufacturer, Mat performs system design and overall systems integration.

A night owl renowned for his patient personality, he is an amateur blacksmith and carpenter.

He and his wife hold the world record for the world’s deepest wedding, held 1,000 meters below the ocean’s surface, off the coast of Nassau. They and their newborn daughter reside in Vero Beach, Florida.


ladd1Lawrence “Ladd” Borne has over 25 years of experience in the design, construction and operation of subsea systems, including manned and autonomous underwater vehicles, environmental sensor platforms and ocean renewable energy devices. He has managed multi-million-dollar projects including the world’s first DNVGL-classed, two-person, full ocean-depth submersible, the Triton Limiting Factor. Ladd was previously the president and chief editor of Ocean News & Technology Magazine and Environmental, Coastal and Offshore (ECO) Magazine, and he was the engineering manager at Harbor Branch Oceanographic Institute.

Ladd has a B.S. in aerospace engineering from Embry-Riddle Aeronautical University and holds a professional engineering license in the state of Florida.


sara1With over 15 years of administrative experience in office management and customer service, Sara assists in the development and implementation of policies and procedures, maintains accounts payable and receivables and serves as the facilities manager. Sara received her bachelor’s degree in marine biology/aquaculture and her master’s degree in communication from Florida Institute of Technology.

Recently moving back to Florida after raising her family in Massachusetts for the past 13 years, Sara enjoys hanging out with her kids, her husband and their family dog. She has an affinity for volunteering and serves in her children’s school PTOs. She also has a deep passion for dancing and theatre.


bill1Bill Sellinger is a U.S. Army veteran and electrical engineering technician who has nearly 50 years of experience and a proclivity for getting the job done.

After being drafted to the Army for two years, Bill enlisted for an additional year to gain experience in the Army Air Defense Command school in equipment training. His military experience working with high-powered illuminating radar led him to Astronautics Corp. in Milwaukee, Wisconsin, where his lab work helped develop cockpit instrumentation.

After seven years at Astronautics, Bill left to attend Milwaukee Area Technical College, studying electrical technology with a minor in biomedical engineering. Shortly after graduation, he moved to Florida, where he spent 17 years helping develop medical imaging equipment.

Following this, his journey led him back to military projects, this time on the civilian side working on communications systems for another 17 years. After six years of retirement, Bill felt the lure of circuit boards and soldering irons calling his name, and he followed the call into the lab of Arctic Rays, where he currently serves as an electronics technician.

Bill’s calm demeanor and penchant for meeting people where they are make him a relatable teacher. He equally enjoys the music of Woodstock and modern rock music, and in his spare time, he delights in the wonders of nature, the challenge of home projects and the joy of his wife, two sons and granddaughter.
