Applications Engineer
$140,000–$140,000 year
On-siteTorrance, California, United States
Job Summary
Develop early-stage technical architectures, costing models, and proposals for new commercial marine projects by partnering with business development as the primary technical touchpoint. Drive the creation of internal sizing and estimation tools to automate application engineering, while sizing complex electrical equipment like 1000V DC busses and multi-MWh energy storage systems. Generate high-level CAD layouts to validate space claims and estimate costs and material take-offs to own final pricing roll-ups and project margins. Collaborate with engineering, supply chain, and technical writing teams to translate architectures into compliant bid packages, presenting technical solutions to clients and naval architects. This full-time, on-site role at Arc's Los Angeles headquarters supports our mission to electrify the marine industry through proven technology and a pipeline spanning every vessel type.
