• Full‑Stack & Hardware‑Centric Optimization:
  Work directly with quantum compiler, cloud, and hardware engineering teams to build highly optimized hybrid workflows tuned for IonQ’s trapped‑ion architecture.
• Rigorous Algorithm Analysis:
  Conduct deep technical evaluations comparing quantum algorithms against state‑of‑the‑art classical algorithms to identify performance and scaling characteristics.
• Academic Strategy & Advocacy:
  Act as a primary advocate for IonQ’s academic presence by engaging with UMD faculties and initiating impactful research projects.
• IP & External Influence:
  Build a robust portfolio of foundational IP and peer‑reviewed publications, representing IonQ’s technical vision at conferences and in high‑level discussions.

• Doctorate or equivalent experience with 3+ years in quantum computing; background in Physics, Computer Science, Mathematics, Chemistry, or another STEM domain.
• Demonstrated expertise in FASQ algorithms and deep familiarity with trapped‑ion quantum computers.
• Proficiency in error mitigation techniques and advanced quantum compilation strategies.
• Proven track record of developing novel algorithms with peer‑reviewed publications and production‑grade codebases.
• Strong communication skills across academic and business audiences.
• Proficient in Python, Qiskit (or similar SDKs), HPC tools, and responsible use of AI tools.

• Five or more years of professional experience developing end‑to‑end solutions for realistic industry problems.
• Experience applying commercial tools to solve practical problems.
• Active contributor to the FASQ community, including foundational libraries, simulators, or compilers.
• Portfolio of invited talks, software repositories, licenses, or patents demonstrating a respected voice in the quantum ecosystem.
• Success working with internal and external partners to deliver technical solutions.
• Excellent collaboration and communication skills bridging academic research and commercial impact.
