Senior/Staff Manufacturing Engineer – Advanced Processes

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 Sr./Staff Manufacturing Engineer - Advanced Processes, Inspection & Test, you will be responsible for developing, testing, deploying and scaling the processes, inline inspection and electrical test strategies that guarantee high process capability at line rate for our high-volume transformer assembly lines. This role spans medium to high viscosity potting and dispense systems, surface treatment, high-speed plastic welding – from void, surface energy and delamination detection to a variety of electrical tests. You will work closely with product, mechanical and electrical design teams early and often through DFM, design processes from a first principles approach and close the feedback loop to ensure both the product and the lines that make it are robust. You will collaborate closely with external suppliers and equipment partners to land scalable, reliable and highly repeatable equipment lines and processes, owning them from concept to production ramp. How You Will Contribute Lead development of inline inspection, process monitoring and automated electrical test across the Transformer Assembly line, from concept and vendor selection through FAT/SAT, commissioning, validation and rampDevelop and deploy high-speed automated inspection of potted assemblies for voids, delamination, incomplete fill and cure defects – using technologies such as inline X-ray/CT, ultrasonic, thermography and machine visionDevelop surface treatments processes such as atmospheric plasma/corona treatment, solvent/chemical cleaning and adhesion preparation along with inline verification of treatment uniformity and quality (surface energy, contact angle etc)Architect and deploy automated high volume electrical test equipment – capacitance, inductance, DC resistance, conductivity/resistivity, impulse, AC resistance, hipot and partial discharge – including test sequencing, fixturing, shielding/noise control, limit setting to balance cycle time, yield and escape riskPartner with other manufacturing engineers in developing high-viscosity 1k/2k potting and dispense systems, high-speed plastic welding processes like ultrasonic, hot plate and IR welding with robust inline process monitoring and destructive/non-destructive weld validationLead MSA, Gage R&R and test method validation for inspection and electrical test systems, including golden/limit samples and correlation to lab methods such as sectioning and CTApply PFMEA, control plans, SPC methodology and structured problem solving to maintain world class process capabilitySupport automation integration with robots, conveyors and inline QA What You Will Bring Must-Have Requirements 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.
