What to Expect
Heron Power is a startup company building cutting-edge power electronics for the 21st-century grid. We aim to debottleneck the growth of electricity generation and consumption with scalable, innovative, and less costly hardware solutions, accelerating the electrification of everything.
Our first goal is to build better converters (inverters & rectifiers) to connect large-scale renewables, storage, and loads to the grid. Heron Power’s leadership team is made up of seasoned veterans who have designed and shipped gigawatts of power conversion products over the past decade.
We understand that no one individual knows everything. We will all learn a lot together and from each other. We strive to build a collaborative, enriching environment conducive to personal, technical, and career growth. You can expect to work in a dynamic and collaborative environment, driven by first principles engineering, solving difficult problems.
Job Overview
As a Mechanical Engineer Intern, you will work alongside a team of experienced engineers to design, develop, and validate cutting-edge medium-voltage power electronics systems. You will design a wide range of associated parts and assemblies using a first principles design approach. Your role will involve performing a variety of tasks, including CAD, analysis, prototyping, testing, and hands-on work. You will collaborate closely with electrical, test, and manufacturing engineering teams, as well as external suppliers.
This internship is ideal for students passionate about mechanical design and electronics who are excited to build scalable, efficient, and reliable energy systems that will shape the future of the grid.
How You Will Contribute
-
Design parts and assemblies for power converters, such as enclosures, plastics, heatsinks, insulators, transformers, connectors, PCBAs, bolted joints, and adhesive joints
-
Employ manufacturing processes such as fastening, sheet metal bending, stamping, injection molding, diecasting, extruding, and dispensing
-
Design with a first principles approach, optimizing parts through analysis (e.g. structural, thermal, tolerance)
-
Create 3D designs and 2D drawings using CATIA V6/3DX
-
Perform hands-on work such as prototyping and testing
-
Collaborate with different engineering disciplines, including mechanical, electrical, manufacturing, and reliability teams, as well as external partners and suppliers
