Applications Engineer

About the role

The Applications Engineer will partner with the business development group to develop technical solutions and architectures for new marine projects. They will drive the development of internal sizing and estimation tools, collaborating with design engineers to build robust calculators for electrical loads, thermal limits, and pricing. The role involves sizing and specifying complex marine electrical equipment, generating high-level CAD layouts, estimating costs and material take-offs, and presenting technical architectures to clients. The ideal candidate will have 2+ years of experience in the marine industry, strong understanding of marine electrical architectures, and proficiency in relevant software.

Responsibilities

• Partnering with business development group to develop concept solutions and architectures for new marine projects.
• Driving the development of internal sizing and estimation tools.
• Collaborating with design engineers to build robust calculators for electrical loads, thermal limits, and pricing.
• Sizing and specifying complex marine electrical equipment, including 1000V DC busses, multi-MWh energy storage systems, switchgear, and electric propulsion motors.
• Generating high-level CAD layouts to validate space claims for major equipment.
• Estimating costs and material take-offs (BOMs), taking full ownership of the final pricing roll-up and project margins.
• Collaborating closely with core engineering, supply chain, and technical writing teams to translate architectures into clear, compliant, and persuasive bid packages.
• Evaluating customer requirements, ship specifications, and general arrangements to develop optimized technical proposals that align with the company's mission.
• Presenting technical architectures to clients, shipyards, and naval architects, answering technical questions during the bidding phase with transparency and expertise.

Requirements

• Strong understanding of marine electrical architectures, including diesel-electric systems, fully electric propulsion, and high-voltage DC power distribution.
• Functional knowledge of energy storage systems (ESS), switchgear, power electronics, and power management systems.
• Ability to read, interpret, and create electrical single-line diagrams, system block diagrams, and complex spreadsheets.
• Basic proficiency with CAD software (such as NX or SolidWorks) for conceptual layouts and footprint planning.
• Commercial mindset with the ability to confidently own pricing models and margin outcomes.
• Clear verbal communication and the ability to collaborate effectively in an inclusive, cross-functional environment.
• Strong time management skills with the ability to juggle multiple project deadlines simultaneously.
• Comfortable pushing at a fast but sustainable pace, respecting both the work and your own well-being.
• Comfortable spending occasional time on boats in the field or at shipyards for vessel walks and client meetings.

Bonus Qualifications

• Firsthand experience working on commercial vessels (tugs, ferries) or defense vessels, particularly those with electric propulsion.
• Deep experience with high-voltage battery systems and their associated safety requirements.
• Familiarity with marine classification society rules and regulatory standards (e.g., ABS, DNV, USCG, IEEE 45).
• Experience conceptualizing or guiding the creation of computational tools (e.g., in Excel, Matlab, or Python) for system sizing.
• Familiarity with fluid/thermal cooling systems, sufficient to understand and utilize internal thermal sizing calculators for power electronics.
• Enthusiasm for boating and the water.
