Technical Lead, Simulation and Modeling

About Sygaldry Sygaldry Technologies is building quantum-accelerated AI servers to exponentially speed up training and inference for AI. By integrating quantum and AI, we're accelerating the path to superintelligence, and engineering the conditions for it to scale efficiently and operate affordably. Sygaldry AI servers combine multiple qubit types within a single, fault-tolerant architecture to deliver the combination of cost, scale, and speed necessary for advanced AI applications. We pioneer new domains in physics, engineering, and AI, tackling the hardest challenges with a grounded, optimistic, and rigorous culture. We're looking for individuals ready to define the intersection of quantum and AI and drive its profound global impact. What You’ll Work On As we are just getting started with ASTRA-sim, the Technical Lead, Simulation and Modeling will be empowered to lead the effort, defining the simulation, modeling and emulation roadmap for the company. They will interface with a variety of internal teams and external partners with whom we are planning to collaborate, integrating existing estimation tools into the ASTRA-sim framework. Key responsibilities: - Lead the effort to select and confirm Sygaldry's distributed simulation environment, with ASTRA-sim and Chakra functionality as part of the platform - Set everything up the simulation infrastructure from scratch - Define the simulation, modeling and emulation roadmap for the company - Interface with a variety of internal teams and external collaboration partners - Work with internal teams that have developed estimation tools to coach them and help them integrate these tools into the ASTRA-sim framework Qualifications - MS in Computer Engineering with exposure to computer architectures - Familiarity with Gem5, ASTRA-sim or other similar architecture and distributed simulation platforms - Familiarity with Verilog/VHDL RTL simulation platforms like VCS - Exposure to the simulation environments used by the GPU/XPU supplier, hyperscalers and/or frontier labs for simulation AI workloads on various system and hardware architectures Why This Matters Your work accelerates the path to quantum superintelligence. Each quantum component integrated, each AI model enhanced, each instruction set optimized brings us closer to a future where intelligence and quantum mechanics are inextricably intertwined. We're not building incremental improvements - we're creating exponential transformations that will make AI more affordable, sustainable, personalized, and fundamentally more capable. How We’re Different We’re building the infrastructure for quantum superintelligence and pioneering new domains at the intersection of physics, engineering, and AI. At Sygaldry, curiosity and intellectual courage drive our work. We approach ambitious challenges with a grounded, optimistic, and rigorous culture and know that kind people build the strongest teams. We prioritize mission over ego and collaborate openly with a strong sense of shared purpose. We dream big, yet we execute with a love of detail. Culture & Benefits - The Best of Both Worlds: Access to the industrial-scale compute and hardware resources while retaining the intellectual freedom of an academic environment. - Visa Sponsorship: We know what it takes to make top talent thrive here. We're open to supporting visas whenever possible. - Compensation: We value your high-level expertise. This position offers a salary significantly above standard academic postdoctoral rates. - Benefits: Your well-being matters. We provide company-sponsored health coverage to give you and your family peace of mind. - Connection: Whether it’s company offsite or casual crew socials, we make time to connect, recharge, and have fun together. - Time Off: We trust you to take the time you need. Unlimited PTO so you can rest, recharge, and come back ready to make an impact. This position can work out of our San Francisco or Ann Arbor offices. Competitive compensation package is based on experience and location. Expected base salary range: San Francisco, CA: $220K-$250K Ann Arbor, MI: $180K-$210K We encourage applications from candidate with diverse backgrounds. We are an equal opportunity employer, and we do not discriminate on the basis of race, religion, color, national origin, sex, sexual orientation, age, veteran status, disability, genetic information, or other applicable legally protected characteristics. We encourage you to apply even if you do not believe you meet every single qualification.
