About Sine Engineering
Sine Engineering builds the technology behind reliable drone autonomy, including communications, navigation, and control systems that enable coordinated multi-drone operations at scale. More than 200 UAV manufacturers rely on our technology, and our solutions power many of today's active interceptor operations.
Through our dual-use platform, we support civilian innovation while helping democratic nations strengthen their technological advantage.
Any drone. Any scale. Anywhere.
We build resilient communication, navigation, and coordination systems for the age of autonomy.
We are looking for Physical Design Engineer (all levels) to join our team in building next-generation System-on-Chips (SoCs) from the ground up.
Responsibilities
Drive the physical implementation flow, from synthesis through place-and-route, timing closure, and GDSII sign-off.
Contribute to one or more of the following areas:
Synthesis and constraint development (SDC), including handoff between front-end and back-end teams.
Floorplanning, power planning, placement, clock tree synthesis, and routing for SoC blocks and full-chip integration.
Timing closure across PVT corners and operating modes, including STA, ECO planning, and sign-off.
Physical verification, including DRC, LVS, ERC, antenna checks, and electromigration/IR-drop analysis.
DFT integration and implementation, including scan insertion, compression, MBIST, boundary scan, and ownership of test pattern generation flows.
Low-power implementation, including UPF/CPF co-design flows, power domains, level shifters, isolation, and retention strategies.
Package definition and co-design, including pinout planning, bump/ball assignment, package-aware signal and power integrity, and collaboration with package and board teams.
Tape-out preparation and sign-off, including GDSII generation, foundry deliverables, and DRC/LVS-clean handoff.
Skills and Requirements
Background in SoC physical design, ranging from recent graduates with strong fundamentals and relevant project experience to senior engineers with multiple successful tape-outs.
Working knowledge of the complete RTL-to-GDSII flow (appropriate to experience level), including synthesis, place-and-route, STA, and physical verification.
Familiarity with industry-standard EDA tools such as Synopsys Design Compiler, Fusion Compiler, IC Compiler, Cadence Genus, Innovus, Siemens Calibre, or equivalent solutions.
Solid understanding of timing analysis, CDC, low-power design methodologies, and design-for-test concepts.
Scripting proficiency in Tcl, Python, or Perl for flow automation and analysis.
Strong debugging skills and a structured approach to resolving complex implementation challenges.
A proactive attitude, strong ownership mindset, and eagerness to learn and grow with the team.
Nice to Have
Experience with package definition, pinout optimization, and package/PCB co-design.
Experience with mixed-signal or RF SoC implementation and analog-to-digital integration.
Knowledge of signal integrity, power integrity, and electromigration analysis.
Experience with hierarchical implementation methodologies and large-block partitioning.
