San Francisco Office
Full-time
Hybrid
Director/ExecutiveFlux is a company focused on revolutionizing hardware design through AI technology. They are seeking an experienced electrical engineering leader to own hardware design practices, guide the development of their AI Hardware Engineer, and grow the hardware design function and team.
Artificial Intelligence (AI)Generative AIHardwareSoftware
Responsibilities
Drive ECAD feature design & specs – Craft product requirements for core ECAD behaviors across placement/routing, constraints management, stackup, impedance control, DRC/DFM, manufacturing outputs, and prototyping workflows. Co-author specs, validate by running dogfooding initiatives, beta programs, and scaled user feedback
Be the design partner to AI/ML – Teach the world’s first AI hardware engineer how to design successful products. Define best practices, guardrails, and evaluation harnesses; curate datasets; review AI‑generated designs; create the AI expertise that will help more people build successful hardware on their first production run, without releasing the magic smoke
Build out the Hardware Design function – Start as a hands‑on manager with two existing reports. Over time, refine the team's core responsibilities, and build a larger team that produces reference designs, demos, product specs, training, and field feedback loops
Develop real hardware – Lead quick‑turn-around prototypes (from schematic to bring‑up) that exercise product/AI capabilities. Instrument designs for SI/PI and power/thermal validation; close the loop with data
Amplify user insight – Adopt ownership and improve upon current user experience signals, feedback loops, and channeling user input into our iterative product design. Strategically invest in deeper customer relationships. Champion the user’s voice in cross‑functional forums. Partner closely with our software engineering department in ensuring AI evaluations are reflective of real-world user requirements
Product – Be the "voice of the customer" within the organization, addressing vision, strategy, research & discovery, prioritization and cross-functional leadership
Qualification
Required
Deep EE breadth + depth with real products in the field. Comfortable spanning RF & wireless: from sub‑GHz to mmWave; matching, filtering, antenna/feed layout
EMI/EMC & ESD: design‑for‑compliance, grounding/return paths, shielding, filtering
Power electronics: DC‑DC (buck/boost), PMICs, PoE, motor/actuator control, power sequencing, efficiency/thermal trade‑offs
Analog & mixed‑signal: sensor interfaces, data converters, low‑noise design
High‑speed digital: DDRx, PCIe/SerDes, USB‑C/USB4, MIPI, Ethernet (1G–25G+); timing, skew, and equalization considerations
SI/PI: signal/power integrity analysis, decoupling strategies, return‑path control
PCB/stackup expertise: material selection and stackup definition, controlled impedance, differential pair tuning & length‑matching, via strategies (blind/buried, microvia, backdrill), HDI (high‑density interconnect), panelization, and build rules with fabs/EMS
DFM/DFT & manufacturing: hands‑on bring‑up and debug, test coverage, fixture definition; tight collaboration with CMs/ODMs
Tooling fluency: meaningful time in multiple ECADs (e.g., Altium, Cadence Allegro/OrCAD, Mentor Xpedition, KiCad, Zuken) and experience with simulation tools (SPICE, SI/PI such as ADS/HyperLynx/SIwave; 3D EM such as HFSS), plus lab instrumentation (oscilloscope, VNA, logic analyzer, power analyzer)
Product sense & communication: ability to turn messy user needs into simple workflows; excellent written specs, diagrams, and presentations; confident with senior leadership and deep‑dive technical reviews
Leadership at multiple altitudes: thrive as both a hands‑on engineer and a manager; co-develop core ECAD product strategy. Hire, mentor, and scale processes while staying close to the work
Preferred
Experience in a larger technical org (e.g., hardware product management or lead EE for critical subsystems at a world‑class company) with a track record of shipping at scale
On the ground factory and test, mass production, and quality/yield optimization experience. Actively participating in builds and carrying key responsibilities to realize designs at scale
Prior design‑partner or customer‑facing role (product management, applications, FAEs, field engineering, or cross‑functional liaison) that turned feedback into product wins
Hands‑on across ECAD platforms; passion for great engineering tools and workflows
Practical exposure to AI/ML (prompting/evaluation, data curation/labeling, or integrating ML‑assisted design tools)
