Mechanical Engineer, Product Integration
$120k - $220k USD
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’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, Product Integration, you will be responsible for integrating mechanical, electrical, and thermal subsystems into complete, production-ready power converter products, with a strong focus on packaging. You will work at the system level, ensuring that enclosures, structures, cooling, insulation, cabling, and assemblies come together into robust, manufacturable, and serviceable products. You will collaborate closely with mechanical, electrical, test, reliability, and manufacturing teams to drive integration decisions from early architecture through high-volume production. You will work closely with the manufacturing team to develop product manufacturing concepts, evaluating tradeoffs across cost, schedule, design complexity, and scalability. You will own mechanical integration across subsystems, identify and resolve interface risks, and ensure designs meet performance, reliability, safety, and manufacturability requirements.
How You Will Contribute
Own mechanical system integration and packaging for medium voltage power converters, ensuring compatibility across electrical, thermal, structural, and manufacturing requirements
Define and manage mechanical and packaging interfaces between subsystems, including enclosures, power electronics assemblies, busbars, cable routing, cooling systems, insulation, fasteners, and assembly hardware
Develop and evaluate product manufacturing trade studies, balancing performance, cost, lead time, reliability, serviceability, and scalability using first principles and engineering judgment
Make informed design decisions that consider manufacturing processes, assembly sequence, tolerance stack-ups, supply chain constraints, and cost targets
Identify and resolve integration and packaging risks related to tolerances, grounding, creepage/clearance, sealing, thermal expansion, shock/vibration, and assembly accessibility
Create and maintain 3D system layouts, packaging studies, interface definitions, and 2D drawings
Support prototype builds, system bring-up, and validation testing through hands-on involvement
Collaborate closely with electrical, manufacturing, test, reliability, and supply chain teams, as well as external partners and suppliers
Support transition from prototype to high-volume production, including DFM/DFA reviews and factory readiness
What You Will Bring
We have a short list of must-have requirements. We prioritize a strong grip on first principles, hands-on skills, and a sense of initiative. Domain-specific knowledge and experience will help determine the career level for each hire.
Must-Have Requirements
5+ years of full-time industry experience integrating complex electromechanical products
Bachelor’s degree in mechanical engineering, mechatronics, or similar
Strong experience working with 3D CAD (bonus for CATIA V6/3DX)
Strong engineering fundamentals, including a working understanding of electrical and thermal systems
Experience defining and managing interfaces between mechanical and electrical subsystems
Experience supporting prototype builds and resolving integration issues hands-on
Familiarity with high-volume manufacturing considerations and assembly processes
Excellent communication and interpersonal skills
Ability to work independently and as part of a team
Strong problem-solving skills and attention to detail
Nice-to-Haves
Experience with GD&T and tolerance analysis
Experience with reliability and validation testing, as well as DFMEAs
Experience with creepage/clearance, grounding, insulation systems, and safety requirements
Experience with thermal systems, including air or liquid cooling integration
Experience with PCBAs, connectors, fuses, and other electronic components
Experience with FEA, CFD, multi-physics modeling, or associated software (Ansys, MATLAB, Python, Simulink, StarCCM, etc.)
Experience with product lifecycle management (PLM) and controlled release processes
Experience with medium voltage (34.5kV) or grid-related products, such as converters, switchgear, circuit breakers, insulation, and shielding
