What are the responsibilities and job description for the Sr. Embedded Firmware Engineer: Underwater Robotics position at Fleet Robotics?
Job Highlights
Fleet Robotics is a green-tech startup developing an underwater robot to inspect and maintain ship hulls. At Fleet, we are looking for an exemplary embedded firmware engineer to lead our embedded software development. Challenges include designing robust, real-time control systems for underwater navigation, sensor integration, and autonomous operation in challenging marine environments. The ideal candidate has experience developing production-grade embedded firmware, implementing real-time control systems, and optimizing code for resource-constrained environments. Experience with underwater robotics, sensor interfacing, and communication protocols is highly valued. As one of the company's pivotal employees, this role offers the ability to make significant contributions to a novel and meaningful environmental application working with a small, close-knit, and fast-paced team.
Meaningful and Impactful
We are tackling a thousand-year-old problem: the growth of biofouling on ships. Biofouling is the growth of microorganisms, algae, barnacles, and larger ocean organisms on the ship’s hull. As a ship delivers goods around the world, the growth of these organisms significantly increases the drag forces on the hull and in doing so, significantly increases fuel consumption. Ships are the world’s largest consumers of carbon-heavy fuels (called bunker fuels).
Conventionally, the commercial shipping industry handles biofouling in two ways: preventatively, by coating the ship’s hull in a highly toxic paint that discourages growth, and reactively, by stopping operations every 6-months or so to have divers scrape off years of fouling (along with some toxic paint). This is akin to deciding never to brush your teeth because you go to the dentist every five years. There is a better way.
Our small autonomous robots live on the side of a ship’s hull for years, gently removing the earliest stage of biofouling on a regular basis. This early-stage biofouling is easy-to-remove slime. The technical challenge lies in having a robot that can withstand a marine environments, adhere to the ship hull while it is underway, and clean entirely autonomously. By removing slime often and early, we prevent the growth of macrofouling, significantly reduce fuel consumption, and prevent the spread of invasive species from port to port.
Your Role
You will spearhead the development of all embedded firmware for the robot control, working at the intersection of control systems and sensing. As the technical lead responsible for developing and maintaining the embedded firmware, you will work directly with the electrical and autonomy teams to design our next generation of robot platforms that meet the needs of customers. Our fleet of robots must use coordinated planning and real-time decision-making to combat the dynamic and uncontrolled environment that is present on ship fulls. Candidates must be able to develop robust firmware to control robot motion and behaviors along with consistent data collection to supply to the complex path-planning and autonomy software. The side of a ship provides unique challenges that require novel solutions for sensing the robot and its environment, along with needing reliable control over all robot motion. Some of these challenges include dealing with harsh and irregular environmental conditions, utilizing limited or varying sensor data, lack of communication while underwater, near-zero visibility, and many others. This challenging but rewarding environment creates an opportunity where creative problem-solving and critical thinking are crucial to success.
