Top Tech Jobs & Startup Jobs

Lead development of system-level behavioral models and link simulations for silicon photonics transceivers. Perform link-budget and channel modeling, optimize TX/RX architectures and DSP, debug simulations, correlate pre- and post-silicon results, and collaborate cross-functionally to produce IBIS-AMI models and documentation through product release.

Lead mixed-signal ASIC design for silicon photonics driver ICs supporting 100G–400G per lambda. Define full-chip electrical specs, design high-speed datapaths and control circuits, author verification/test plans, debug silicon and system issues during bring-up, drive yield improvements, and mentor analog, digital, and validation engineers across cross-functional teams.

Develop and refine backend methodologies and flows from RTL to GDS, advance signoff flows (physical synthesis, place and route, power optimization, timing and physical closure), collaborate to enhance implementation tool flows, and work with advanced silicon technologies to deliver complex VLSI devices.

Designs, implements, migrates, and troubleshoots Cisco Collaboration/UC solutions. Works with customers and partners to create designs, migration plans, dial-plans, provision phones, build test environments, and deliver project deliverables and knowledge sharing.

Senior solutions architect advising central government and defence CTOs/CIOs. Lead multi-domain architectures (networking, security, cloud, collaboration), shape strategic bids and digital transformation programs, liaise with cross-functional teams, and influence long-term technology roadmaps for mission-critical national infrastructure.

Design, implement, and maintain scalable iOS or Android features and shared mobile components. Improve performance, reliability, observability, and user experience. Debug production issues, collaborate cross-functionally, and use automated testing, CI/CD, and telemetry to ensure high-quality mobile releases.

Lead design, implementation, optimization, and troubleshooting of Cisco enterprise solutions for customers (Japanese environment). Support presales, build test labs, produce HLD/LLD/MOPs, and enable smooth technology transitions. Work as an individual contributor collaborating across teams and partners.

Design and develop pre-silicon emulation environments and infrastructure. Implement tests to generate complex traffic and performance scenarios, debug RTL/emulation prototypes, and collaborate with design, DV, power, and post-silicon teams and emulation vendors to catch issues before silicon.

Perform backend VLSI implementation from RTL to GDS including physical synthesis, place-and-route, floorplanning, timing closure, and optimization. Analyze timing, congestion, power, area, and DRC/LVS issues. Collaborate with cross-functional teams to debug implementation problems and improve backend flows and methodology.

12-month early-career sales accelerator where associates train in sales fundamentals, collaborate with solutions engineers, use AI-enabled simulations, complete rotations across Collaboration, Security, Networking and Cloud, and transition into Inside Account Executive roles. Program includes mentoring, certification, competency checkpoints, and sales incentive opportunities.
