Founding Security Engineer

Ricursive Intelligence is a frontier AI lab building self-improving systems, starting with chip design. We are reinventing chip development and closing the loop between AI and the hardware that fuels it, recursively accelerating the path to artificial superintelligence. Backed by $335M from Sequoia, Lightspeed, DST, and NVIDIA Ventures, we are a small and fast-paced team where every hire shapes the work.
The company has unmatched talent density, including IMO, IPHO, and IOAA gold medalists, pioneers who made prior breakthroughs in chip design: AlphaChip (Nature 2021), ePlace (DAC Best Paper Nominee 2014), RL-CCD (DAC Best Paper 2023), INSTA (DAC Best Paper 2025), and C3PO (ASP-DAC Best Paper 2026), chip leads for Apple (iPhone, iPad, M1) and Google (TPU, OpenTitan), and top researchers and engineers from Anthropic, Google DeepMind, Stanford, and MIT.
Ricursive is hiring a best-in-class founding professional to lead our IT and holistic security efforts. We’re looking for a hands-on builder with deep technical experience to own our defensive posture, spanning internal network hardening, cloud infrastructure, and defense against social engineering attacks. You will architect and manage the IT systems that protect our core and our partners' intellectual property, ensuring a pragmatic balance between world-class security and research speed.
