Product Security Engineer

Sea Machines is a fast-growing startup that is leading the new high-tech sector of autonomous

technology for marine vessels. We are passionate about applying practical A.I. to the massive

global ocean transportation market. Our products provide ships and workboats the intelligence to

work remotely and give maritime operators the tools to effectively communicate with them.

Based in Boston and operating globally, the company is crewed by an experienced team of

mariners, engineers, coders, and autonomy scientists.

Sea Machiners get the unique opportunity to work in a very dynamic domain (the ocean world),

serve and visit people and places around the planet, and solve challenges not seen in most other

robotics sectors.
