Volantis Semiconductor is a hardware company building photonic interconnects (tiny optical waveguides on large substrates) for AI accelerators and datacenter memory pooling. Their technology extends optical reach roughly 100x compared with electrical interconnects, enabling rack-level fast-memory pools with much higher bandwidth and far larger capacity so inference of >10-trillion-parameter models can run at low, SRAM-like latencies. The company has raised an $88M Series A and is backed by investors including Sam Altman and Jeff Dean; its team includes people experienced in co‑packaged optics, HBM, and CoWoS. Volantis targets other hardware and infrastructure builders with photonic AI infrastructure components that reduce $/token and overcome the memory wall for large-model inference.

📋 Description

• Design custom lasers and their integration with the wafer-scale interposer • Contribute to first- and second-generation custom laser designs and their integration with the wafer-scale interposer • Own aspects of qualification and ramp-up of the VCSEL array product line from design and epitaxy through fabrication, testing, and packaging at contract manufacturers • Work with epitaxial wafer vendors and contract manufacturers to ensure epitaxy and mask/fabrication designs can be successfully implemented and repeatably produced • Collaborate with electronics, packaging, and wafer-scale interposer teams to improve VCSEL design for the integrated interposer product, balancing density, yield, and manufacturability tradeoffs • Set technical direction and roadmap based on integrated interposer needs • Drive VCSEL design reviews with other teams

🎯 Requirements

• Deep understanding of VCSEL epitaxy design, fabrication design and process, validation, and qualification • Experience taping out VCSEL epitaxy and mask/fabrication processes • Hands-on experience contributing to an industry-first laser design • Ability to work independently as well as in cross-functional teams including electronics, packaging • Experience using outsourced contract manufacturers for large volume production of VCSELs (nice to have) • Experience with high-density VCSEL arrays and VCSEL polarization stabilization (nice to have) • High speed direct modulation laser diode design/test experience (nice to have) • Understanding of sources of process variation and statistical process control for yield improvement (nice to have) • Laser packaging and/or reliability experience (nice to have)
