Job Title
Senior ASIC Physical Design Engineer
Role Summary
Senior physical-design engineer in the Miniature Device Technologies Group at Johns Hopkins APL. Responsible for digital back-end flow and top-level physical implementation of mixed-signal and digital ASICs used in small, low-power systems for national security applications.
Experience Level
Senior β requires 6+ years of hands-on back-end ASIC design experience.
Responsibilities
Deliver complete, verified top-level ASIC layouts and support the back-end design flow.
- Implement digital back-end flow from synthesis through timing closure and tapeout-ready top-level layout.
- Top-level floorplanning and design partitioning for timing, power, and area goals.
- Perform timing analysis and closure at RTL and gate-level.
- Insert SCAN and BIST to maximize defect coverage.
- Perform physical verification including DRC, LVS, MCD, and DRC+ using foundry tools.
- Perform custom physical layout and top-level custom modifications as needed.
- Debug back-end issues with digital designers and support fixes in RTL and gate-level flows.
- Contribute to process selection and ASIC technology characterization for new designs.
- Drive tooling/environment improvements and develop scripts to streamline flows.
- Mentor junior physical-design engineers and collaborate across design, verification, and software teams.
Requirements
Must-have technical skills, security eligibility, and relevant experience.
- 6+ years of specific experience performing back-end ASIC design (synthesis, place-and-route, timing closure, signoff).
- Proficient with Cadence back-end design tools for flow implementation.
- Proficient with Siemens Calibre physical verification tools (DRC/LVS/MCD/DRC+).
- Experience with SCAN and BIST insertion and related test methodologies.
- Ability to obtain an Interim Secret security clearance by start date and ultimately a Secret clearance; U.S. citizenship is required for clearance eligibility.
Nice-to-have:
- Experience with custom layout in Cadence Virtuoso.
- Familiarity with Siemens ASIC design toolchain for back-end flow.
- Extensive knowledge of ASIC technology characterization for process selection.
- Active security clearance or prior single-scope background investigation.
Education Requirements
Associate's degree in a technical field, or an equivalent combination of experience, education, and/or certifications is acceptable.
