Senior DSP Developer - Heterogeneous SoCs

At Teradar, we are pioneering a new era in perception with the world’s first automotive terahertz vision sensor, delivering ultra-high-resolution imaging in any weather condition. Founded in Boston, Teradar’s solid-state, chip-scale technology unlocks safer, smarter vehicles and opens the door to transformative applications in mobility, defense, and beyond.

We are looking to hire a DSP Software Developer: someone capable of partitioning real‑time signal processing pipelines across heterogeneous DSP cores, squeezing every cycle out of shared‑memory hierarchies, and orchestrating data movement over a Network‑on‑Chip.

You’ll work close to the metal on both fronts: scaling workloads across many cores and optimizing the hot inner loops on each one.

• Architect and implement multicore software for radar signal processing on an SoC, partitioning pipelines across multiple cores connected by a network‑on‑chip.
• Design data and task decomposition strategies that balance compute load, minimize inter‑core communication, and exploit pipeline, data, and functional parallelism across radar processing stages.
• Manage a multi‑level memory hierarchy (core‑local, cluster‑shared, and SoC‑global) - placing buffers, sizing working sets, and orchestrating DMA transfers to sustain high memory throughput and keep cores fed with radar data cubes while hiding stalls behind useful work.
• Develop and optimize per‑core radar kernels (FFTs, filters, matrix operations, CFAR variants, MIMO processing) using SIMD, VLIW, fractional arithmetic, and intrinsics.
• Build, use, and maintain pre‑silicon validation platforms such as virtual prototypes for early multicore software development, performance projection, and testing.
• Profile end‑to‑end radar pipelines across cores - identifying load imbalance, NoC contention, memory bandwidth bottlenecks, and synchronization overhead - and iterate on partitioning, scheduling, and data layout to optimize performance, power, and area trade‑offs.

• Strong experience developing multicore embedded software on an SoC, including workload partitioning, scheduling, and load balancing across cores.
• Hands‑on experience managing shared and distributed memory across a multi‑level memory hierarchy, including explicit DMA‑driven data movement, double/multi‑buffering, and techniques for sustaining high memory throughput under real‑time constraints.
• Working knowledge of bare‑metal programming and/or real‑time operating systems, including boot flow, linker scripts, memory maps, interrupt and exception handling, and real‑time task scheduling.
• Solid understanding of computer architecture and micro‑architecture fundamentals.
• Proficiency in C/C++ along with SIMD and VLIW programming models, intrinsics, and fractional arithmetic applied to radar or DSP kernels.
• Familiarity with radar signal processing concepts - FMCW radar, Range/Doppler/Angle estimation, FFTs, CFAR detection, beamforming, MIMO, and tracking, and the data‑flow and bandwidth characteristics they impose on the processing pipeline.
• Exposure to virtual prototypes or pre‑silicon validation platforms.
• Ability to analyze and resolve performance bottlenecks spanning compute, memory bandwidth, NoC, and synchronization, and to optimize for PPA across the full multicore radar pipeline.
