We foster a culture built on mutual trust, high ownership, and zero bureaucracy where every team member is empowered to do the best work of their career.

· Cutting-Edge Silicon Impact: Work on foundational mixed-signal silicon architectures, high-resolution data converters, and advanced custom ASICs.

· Deep Empathy & Care: Industry-leading employee wellness, adaptable hybrid workflows, and an inclusive culture centered on trust and mutual respect.

· World-Class Mentorship: Collaborate directly with veteran semiconductor architects, distinguished research advisors, and senior VLSI leaders.

· Wealth Creation & Ownership: Generous equity ownership (ESOPs) ensuring every engineer shares directly in the long-term enterprise value we build.

Flexible engagement

· Flexible Engagement Models: We offer full-time leadership roles,



executive advisory/consulting arrangements, and milestone-based project engagements to accommodate senior veterans and top specialists.

· Internship-to-Full-Time (PPO) Track: Structured 3-to-6-month research internships for graduating M.Tech / Ph.D. scholars with direct Pre-Placement Offers (PPOs) and accelerated equity vesting.

· Competitive Compensation & ESOPs: Highly competitive compensation packages, performance incentives, and meaningful founding stock options (ESOPs).

· State-of-the-Art EDA & Compute: Access to industry-leading Cadence, Siemens EDA (Calibre), and Synopsys tool suites on high-performance compute infrastructure.

· Hybrid & Flexible Work Culture: Trust-based work environment with hybrid/remote flexibility across major hubs (Vijayawada, Bengaluru, Hyderabad). Role Overview

- Role Level: Executive Leadership / Chief Silicon Architect (Full-Time or Senior Principal Consultant)
- Location: Vijayawada / Bengaluru / Hyderabad / Hybrid (Flexible)
- Experience: 8+ years in Advanced AMS/SoC IC Architecture & Tape-out Execution Role Description As Chief Silicon Architect, you will lead the complete silicon strategy, microarchitecture definition, PDK integration, and multi-vendor physical verification sign-off for complex custom Analog/Mixed-Signal ICs and sensor interface SoCs. You will define product roadmaps, lead transistor-level architecture, supervise SPICE simulation audits, and serve as the primary technical authority for full-chip tape-outs.





Key responsibilities · Lead microarchitecture and full-custom implementation of monolithic mixed-signal ICs, specifying analog front-ends, high-speed data converters (high-resolution Column SAR ADCs), precision bias circuits, and digital timing interfaces.

· Supervise foundry PDK setup, SPICE model card verification (BSIM-IMG, BSIM4, PSP), and extreme multi-corner simulation sign-offs in Cadence Spectre / Spectre-X.

· Lead multi-vendor physical verification sign-off audits using Siemens Calibre (DRC, LVS, PEX, PERC, DFM), Synopsys IC Validator (ICV), and Cadence Pegasus to guarantee zero-defect GDSII tape-out readiness.

· Drive Power, Performance, and Area (PPA) optimization across all owned analog and digital silicon blocks.

· Architect silicon-level hardware security locks (including OTP key provisioning and anti-tamper logic) to protect core IP.

· Establish single-source specification automation workflows so architectural updates propagate automatically across schematics, register maps, testbenches, and drivers.

· Build, mentor, and direct the full engineering team across Analog AMS, Digital RTL, Systems Automation, and Physical Layout.

Qualifications and skills

· Ph.D. or M.Tech in Electrical Engineering / Microelectronics / VLSI Design from a premier institute (or equivalent deep industry experience).

· 8+ years of hands-on experience in full-custom Analog/Mixed-Signal or SoC chip design with proven silicon tape-outs brought to successful fabrication.

· Deep mastery and sign-off authority in Siemens Calibre (DRC, LVS, PEX, DFM) and Cadence Virtuoso / Spectre toolchains.

· Strong understanding of advanced node design (FD-SOI and planar/FinFET CMOS), compact device modeling, and corner verification.

·Demonstrated track record of technical leadership, architectural innovation, and end-to-end tape-out delivery.
