Top Tech Jobs & Startup Jobs

Develops, sustains, and improves photolithography processes for semiconductor wafer fabrication. Responsibilities include operating and optimizing DUV and i-line lithography tools, writing recipes, analyzing metrology data, monitoring SPC, controlling defects, improving yield and cycle time, supporting production introductions, and resolving technical issues in a 24/7 fab environment. The role requires extensive hands-on cleanroom work, collaboration with integration and equipment engineering teams, and maintaining production process specifications.

Leads high-fidelity optical, electrical, and thermal simulations for III-V and silicon photonic integrated circuits. Models lasers, modulators, couplers, WDM devices, and hybrids; optimizes RF and optoelectronic performance; collaborates with the in-house foundry and device design teams; establishes process design rules; and performs DRC/LVS for accurate tapeouts. The role also automates analysis, evaluates modeled versus measured performance, and supports products from concept through manufacturing.

Lead high-fidelity optical and photonic integrated circuit modeling for III-V and silicon photonics devices, including lasers, modulators, photodiodes, and passive components. Perform coupled optical, electrical, thermal, and RF simulations; collaborate with in-house fabrication and device design teams; establish design rules; execute DRC/LVS and virtual DOE; and validate models against laboratory data. Support product development from concept through manufacturing while analyzing performance, reliability, and process impacts.

Design, model, and simulate III-V lasers, modulators (EAM, MZM), and photodetectors for silicon photonics integration. Perform RF and optical simulations, impedance matching, layout support, DOE and validation testing, characterization, data analysis, and DFM for manufacturable designs.

Leads semiconductor process integration and technology transfer across customer foundry programs. Oversees prototyping, productization, yield ramps, cycle-time improvements, process module development, DOE, SPC, metrology correlation, defect analysis, and cleanroom problem solving. Manages customer technical relationships, revenue-focused engineering delivery, cross-functional execution, and a team responsible for talent development, resource allocation, and performance management.

Support development and sustainment of metrology for wafer fabrication: partner with engineering teams, analyze metrology data, maintain recipes and operating specs, troubleshoot tools, apply SPC, and train technicians in a cleanroom production environment.

Develop and execute integration plans for semiconductor and silicon photonics devices, correlate device outputs to factory metrics, analyze metrology, propose data-driven process improvements, and drive cross-functional teams to implement high-yield, production-ready processes in a cleanroom/manufacturing environment.

Design, simulate, and optimize high-performance silicon photonics devices (couplers, WDM, polarization components, hybrids). Define fabrication-tolerant layouts, run DOE and validation testing, collaborate with layout and process engineers, characterize devices, analyze data, and produce performance reports to enable manufacturable Si photonics system chips.

Lead design, simulation, and electro-optical characterization of high-speed InP Mach-Zehnder modulators and photodiodes. Drive device modeling, collaborate with layout and process engineers, validate prototypes against models, and support transition to high-volume manufacturing in a fast-paced startup.

Develop and maintain firmware and test software for optical communications modules. Implement embedded C/ARM firmware, control algorithms, and low-level protocols (SPI, I2C). Build and improve C# test applications, automate test equipment (USB, GPIB, TCP/IP), support Linux-based test hardware, and ensure compliance with SFF-8636/CMIS during DVT and customer-facing interface testing.
