Silicon Architect

About Sine Engineering
Sine Engineering builds the technology behind reliable drone autonomy - communications, navigation, and control that keep multi-drones coordinated at once. Over 200 UAV manufacturers rely on our systems, and our technology powers most of the interceptor operations active today. Through a dual-use platform, we support civilian innovation while helping democratic nations strengthen their technological edge.
Any drone, any scale, anywhere - resilient communication, navigation, and coordination built for the age of autonomy.
We are looking for a Silicon Architect to lead the architecture of next-generation application engines and radio communication‑optimized System-on-Chips (SoCs).

You will work alongside an exceptional team of engineers, defining and shaping silicon for resilient wireless applications from the ground up. Multiple positions are open and will be filled on a rolling basis.
Responsibilities
- Specify SoC architectures spanning the full data path - from RF transceiver and PHY/MAC to the application engine and external interfaces
- Drive technology selection and define optimal functionality splits across hardware, software, and multi-die implementations
- Capture use cases and translate requirements for radio, baseband, and application engines into SoC architectural specifications
- Architect memory hierarchies, low‑power strategies, video codec pipelines (H.264 / H.265 / AV1), image/sensor interfaces, CPU/DSP/NPU selection, and optimize data flow between capture, encoding, and radio transmission
- Design SoC architectures for modem systems, including baseband, digital front‑end, and radio
- Collaborate closely with the SoC Architecture team and internal RF, SoC design, system modeling, software, and hardware teams, as well as external partners, across the full development lifecycle - from concept to tape‑out to field validation
Skills & Experience
- 8+ years of experience in SoC architecture or senior SoC design roles
- Deep understanding of SoC architectures
- Background in wireless communication systems and/or complex SoC architectures (e.g., mobile chips)
- Proven experience driving architectural decisions across cross‑functional teams
- Experience specifying and integrating third‑party IP, including technical review of vendor deliverables
- English proficiency at B1 level or higher
Nice to Have
- Experience with cryptography, secure boot, and hardware‑level cybersecurity
- Experience with video and imaging hardware
- Experience with multi‑die or chiplet designs and die‑to‑die interfaces
- Knowledge of network communication protocols - both wired (TCP/IP, UDP, RTP) and wireless (LTE‑M, LoRa, etc.), as well as anti‑jamming / LPI‑LPD techniques
- Experience in defense or dual‑use systems
- Experience with low‑power SoC design
