Job Title
Senior ASIC Physical Design Engineer (with Security Clearance)
Role Summary
Senior engineer responsible for digital back-end physical design and verification of custom ASICs in the Miniature Device Technologies Group at the Johns Hopkins APL. The role covers synthesis through a completed, verified top-level layout ready for tapeout and supports mixed-signal and low-power miniature systems for national security applications.
Experience Level
Senior β requires 6+ years of back-end ASIC design experience.
Responsibilities
Lead and execute digital back-end physical design tasks and support cross-disciplinary integration to deliver tapeout-ready ASICs.
- Implement digital back-end flow from synthesis to completed, verified top-level layout for tapeout.
- Floorplan top-level layout for digital and mixed-signal ASICs; perform design partitioning to meet timing.
- Perform static timing analysis and timing closure activities.
- Insert SCAN and BIST for test coverage and support testability strategies.
- Execute physical verification including DRC, MCD, and LVS checks.
- Debug and resolve back-end issues at RTL and gate-level in collaboration with digital designers.
- Perform custom physical layout and top-level custom modifications as needed.
- Contribute to process selection and ASIC technology assessment for new designs.
- Support tooling/environment improvements and scripting for the ASIC design flow.
- Provide guidance and mentorship to junior physical design engineers and work with cross-functional teams to meet project goals.
Requirements
Must-have qualifications and clearances.
- Minimum 6 years of experience specifically performing back-end ASIC physical design.
- Proven proficiency with Cadence tools for back-end flow implementation.
- Proven proficiency with Siemens Calibre for physical verification.
- Experience with timing analysis, floorplanning, SCAN/BIST insertion, and tapeout readiness.
- U.S. citizenship and ability to obtain an Interim Secret clearance by start date and ultimately a Secret clearance.
- Ability to perform DRC, MCD, and LVS physical verification and debug related issues.
- Strong collaboration, problem-solving skills, and ability to lead technical tasks.
Nice-to-have:
- Experience with custom physical layout in Cadence Virtuoso.
- Experience with Siemens ASIC design tools for back-end flow implementation.
- Extensive experience in ASIC technology characterization for process selection.
- Active security clearance or prior single-scope background investigation.
- Experience scripting or enhancing ASIC design environments and EDA flows.
Education Requirements
Possess an Associate's degree in a technical field, or an equivalent combination of education, certifications, and practical experience. The posting explicitly allows equivalent practical experience in lieu of the degree.
