Silicon Engineer

About Sine Engineering Sine Engineering is a leading global company specializing in the development of advanced radio communication and navigation systems. We design and build mission-critical infrastructure for the multi-million-drone era. At Sine, you will work with cutting-edge technologies tested in some of the world’s most challenging environments, with the opportunity to see your ideas evolve into an ecosystem that contributes to global safety and progress. We are looking for Silicon Engineers (all levels) to join our team building next-generation Radio System-on-Chips (SoCs) from the ground up. Whether your strength is in design or verification, you will work alongside an exceptional team of engineers shaping silicon that powers resilient, high-performance wireless links - from initial RTL to tape-out and field validation. We are hiring across experience levels, from early-career engineers to senior contributors ready to own complex subsystems. Multiple positions across different disciplines are open and will be filled on a rolling basis. Responsibilities RTL design, verification, and/or virtual modeling of SoC blocks across the digital data path - including modem baseband, application engines, interconnects, and peripheral subsystems. For design-focused engineers: Specify and develop RTL (Verilog / SystemVerilog / VHDL), drive micro-architecture decisions, and support synthesis, timing closure, and physical design handoff. For verification-focused engineers: Build testbenches and verification environments (UVM / SystemVerilog), define coverage and verification plans (including formal verification where applicable), and drive blocks to coverage closure and sign-off. For mixed-signal engineers: Specify, design, implement, verify, and validate analog and mixed-signal components for wireless communication systems and custom digital IC blocks (e.g., I/O, frequency synthesizers). Participate in design and code reviews, SoC bring-up, silicon validation, and debugging across RTL, gate-level, and post-silicon stages. Skills & Experience Background in digital design or verification - from recent graduates with strong fundamentals and relevant project work to senior engineers with multiple SoCs brought to silicon. Solid understanding of digital design fundamentals and RTL (Verilog / SystemVerilog / VHDL). For design candidates: understanding of timing, CDC, linting, simulation, and low-power design techniques (scaled to experience level). For verification candidates: understanding of verification methodologies (UVM, constrained-random, coverage-driven), scripting (Python / Tcl / Perl), and simulation flows. Familiarity with SoC concepts: bus protocols (e.g., AXI / AHB), clock and reset architectures, and memory subsystems. English proficiency at B1 level or higher. Nice to Have Experience with wireless/radio SoCs, modem baseband, or DSP blocks. Experience with AI-assisted code generation and tools; curiosity to develop AI-driven design flows. Experience with high-speed interfaces (e.g., die-to-die, MIPI, LVDS). Exposure to formal verification, emulation, or FPGA prototyping. Experience with low-power design. Experience with mixed-signal or analog design. Experience in defense or dual-use systems. Experience with SystemC and virtual modeling. Open-source hardware contributions, academic publications, or relevant project portfolios (especially for early-career candidates).
