Employment is contingent on verifying U.S. Person status (e.g., U.S. citizen, U.S. national, U.S. permanent resident, refugee, or asylee) due to U.S. export control and government contract restrictions.
IonQ may decline to proceed with an application if the candidate is unable to confirm U.S. Person status for accessing export-controlled technology or qualifying for government contracts work.
For US Non-Technical Jobs, candidates must be a U.S. citizen or national, U.S. permanent resident, or lawfully admitted into the U.S. as a refugee or granted asylum.

The Senior Mask Layout Engineer will join the Fab Tapeout and Validation Team, taking ownership of full-reticle tapeouts for photonic and electronic components used in trapped-ion quantum computers. This role involves developing and maintaining internal Process Design Kits (PDKs) and automated circuit layout libraries, often utilizing Python scripting. The engineer must collaborate closely with design and testing teams to advance new quantum technology for scalable computing, memory, and networking solutions.

Key Responsibilities

Conduct Python-based layout for full-reticle tapeouts with commercial foundries.

Develop and maintain internal component PCell and automated circuit layout libraries.

Interface with designers, test engineers, packaging engineers, and the foundry team to define layout rules and component designs.

Implement physical verification checks of layouts, including Design Rule Checking (DRC) and Layout Versus Schematic (LVS).

Develop detailed documentation of tapeouts and lead layout reviews with other team members.

Work with cross-functional teams to understand circuit requirements and make recommendations to improve design, layout, and test workflows.

Required Skills

Bachelor's degree in Photonics, Physics, Electrical Engineering, or a related field, or equivalent practical experience.

Knowledge of semiconductor manufacturing processes and techniques.

Excellent programming and software skills, including development in an IDE, proficiency with version control software, shell scripting, and code documentation.

2+ years of experience with Python-based mask layout software packages such as Luceda IPKISS, GDSFactory, or Klayout.

Nice-to-have Skills

M.S. or Ph.D. in Photonics, Physics, Electrical Engineering, or a related field.

5+ years experience generating layout files for complex semiconductor flows with custom elements, such as integrated photonics or superconducting circuits.

Past ownership of full-reticle tapeouts with commercial foundries.

Experience with commercial simulation, verification, and layout environments such as Synopsys, Cadence, and Ansys.

Proficiency in physical verification including DRC, LVS, and Electrical Rule Checking (ERC).

Excellent verbal and written communication skills.

Ability to work independently, prioritize tasks, and manage time effectively in a deadline-oriented environment.
