Work closely with circuit designers to translate schematics into robust physical implementations from floorplanning through tapeout.
Own physical verification and signoff closure including DRC, LVS, ERC, antenna, DFM, and EMIR.
Optimize layouts using extraction results to meet performance, matching, noise, and reliability targets.
Contribute to layout reviews and help drive effective layout methodologies and best practices.
Improve layout productivity and quality through automation, scripting, and AI-assisted workflows.
Develop high-performance connectivity IPs used in AI, networking, and next-generation compute systems.
BE/B.Tech or MS/M.Tech in Electrical/Electronics Engineering, Microelectronics, or a related field with 5–10 years of experience in analog, mixed-signal, RF, or custom layout development.
Hands-on experience with layouts for SerDes, data converters, clocking circuits, power management, transceiver building blocks, or related connectivity IPs.
Proven experience in full-custom layout and signoff including RC extraction, DRC, LVS, ERC, DFM, and EMIR.
Exposure to silicon photonics, co-packaged optics (CPO), near-package optics (NPO), optical transceivers, or high-bandwidth connectivity solutions is a strong plus.
Experience with advanced semiconductor technologies including CMOS, FinFET, BiCMOS, or SiGe.
Strong understanding of semiconductor process technologies, device physics, and layout-dependent effects.
Proficiency with Cadence Virtuoso and industry-standard EDA tools.
Experience leveraging automation, scripting, or AI-assisted methodologies to improve layout productivity and quality.
Solid understanding of layout techniques including matching, shielding, clock distribution, power planning, ESD protection, latch-up prevention, manufacturability, and reliability-aware design.
Demonstrated success delivering complex layouts through tapeout.
Ability to work effectively with globally distributed design, verification, CAD, and technology teams.
Experience supporting multiple projects in a fast-paced product development environment.
Work alongside leaders and innovators in the photonics and semiconductor industry
Opportunity to make an impact on the infrastructure powering next-generation AI and high-performance computing
Fast-paced, collaborative, and mission-driven environment
Competitive compensation and benefits
Join us at Lumilens and help shape the future of compute connectivity!
This role develops custom analog, mixed-signal, and RF layouts for high-speed connectivity IP. You will take designs from floorplanning through tapeout, close physical verification, and refine layouts against performance and reliability goals.
Lumilens is a San Jose-based photonics company building optical interconnect infrastructure for large AI data centers. Its LumiCore platform combines in-house silicon photonics, mixed-signal ICs, electrical-optical interposers and optical systems to power pluggable transceivers, near-package optics and co-packaged optics. These products address scale-out networking between racks and scale-up connectivity between GPUs, where copper links face bandwidth and distance limits. Lumilens also develops proprietary manufacturing processes, robotics and automated testing for high-volume optical production. The company emerged from stealth in 2026 and is already shipping its first scale-out product into a hyperscaler's production AI data centers under a multi-billion-dollar customer agreement.
Lumilens offers candidates the opportunity to work on silicon photonics, mixed-signal ICs, optical systems, embedded software, robotics and high-volume manufacturing for AI infrastructure. The company has raised more than $900 million, reached a $5.51 billion valuation and is already shipping products into a hyperscaler's production data centers under a multi-billion-dollar agreement. Its careers material emphasizes significant technical ownership, hands-on collaboration and work across system boundaries. The company is rapidly expanding engineering and manufacturing teams across the US, India and Asia, creating scope to work on products moving from silicon design through qualification and large-scale production.
