About Mixx Technologies Mixx Technologies is building next-generation optical interconnect solutions that enable true system-level integration for hyperscale data centers. We combine expertise in silicon photonics, packaging, fiber connectivity and system integration to deliver products that set new standards for performance, density, and scalability to drive the next generation of artificial intelligence. Position Overview We are seeking a Platform Power Architect to define and own the power delivery architecture for our next-generation optical interconnect modules, from the host connector down to every rail on the electrical and photonic die. In this role, you will set the regulator topology, power budgets, sequencing, and PDN targets for optical modules, and you will drive the schematic-level design that implements them. You will work closely with package architecture, SI/PI, thermal, photonics, and ASIC teams to balance efficiency, noise, density, and cost in heterogeneous packages that combine high-speed SerDes-class electronics, lasers, and thermally tuned photonics.

Key Responsibilities
• Define the module and package power architecture, including rail tree, regulator topology (buck, multiphase, LDO, integrated regulators), and power domain partitioning across electrical IC & photonic IC
• Own the module power budget and industry module specifications, and allocate it across rails, operating modes, and power classes.
• Design power-up, power-down, and fault sequencing that meets host interface and CMIS requirements, including multi-rail ordering, low-power modes, and reset dependencies.




• Select regulators, PMICs, inductors, capacitors, and protection components; perform efficiency, loss, transient, and stability analysis.
• Set PDN target impedance and decoupling strategy for each rail, and drive package and board PDN design with the SI/PI team, including PDN impedance closure and IR-drop analysis.
• Ensure the module meets host supply noise and slew tolerance requirements and its own noise output limits, and define the test methods used to verify them.
• Define power telemetry and control: voltage, current, and temperature monitoring, PMIC control over I2C, and the data the module reports through CMIS.
• Partner with thermal engineering on regulator placement, loss distribution, and hot-spot mitigation inside the module.
• Support bring-up and debug of power delivery on prototype hardware; correlate measurements with simulation and close margin.
• Write power architecture specifications and design reviews, and communicate trade-offs to package, system, and customer engineering teams. Key Qualifications
• Bachelor's in Electrical Engineering or related field; Master's or Ph.
D. focused on power electronics or power delivery is preferred.




• 10+ years of experience in power delivery design for high-performance ASICs, optical modules, networking, or data center hardware, including architecture-level ownership.
• Strong knowledge of DC-DC converter topologies, multiphase regulators, LDOs, PMICs, and control-loop stability.
• Hands-on experience with PDN target-impedance methodology, decoupling design, and IR-drop analysis at package and board level.
• Proficiency with circuit and power simulation tools such as SIMPLIS, LTspice, or PSpice, and familiarity with PDN analysis tools such as Ansys SIwave or Cadence Sigrity PowerSI/PowerDC.
• Experience with power sequencing, protection, and fault handling in pluggable or co-packaged optical modules
• Working knowledge of power-related requirements in industry specifications such as CMIS and optical module MSAs.
• Lab experience with power measurement equipment: power analyzers, current probes, load-step testers, and injection probes for noise and PSRR testing.
• Experience powering lasers, TECs, or thermal tuners for silicon photonics is a strong plus.
• Solid communication skills and the ability to drive technical decisions across multi-disciplinary, multi-site teams. Why Join Us At Mixx Technologies, you'll be part of a fast-moving team rethinking what's possible in AI infrastructure.

We offer
a collaborative culture, deep technical challenges, and the opportunity to shape the mechanics behind the world's most advanced computing systems.
