Senior Audio System Engineer
Context:
GreenWaves is a fabless semiconductor company founded in 2014 and based in Grenoble, France. We design and market ultra low
power processors for energy constrained products such as hearables, wearables, IoT & medical monitoring products.
GreenWaves’ system-on-chips enable companies to develop and bring to market products with new to world features enabled by state
of the art machine learning and digital signal processing techniques. Our leading edge development tools enable audio and machine
learning developers to productively harness the power of GAP processors.
GreenWaves GAP9 processor powers features such as neural network based noise removal and adaptive noise cancellation,
multi-channel spatial sound and listening enhancement technologies in next generation earbuds and headphones with market leading
energy efficiency.
As a growing, talented and highly multicultural team with sharp personalities, we are proud of what we do and how we do it. Our
non-hierarchical culture means living our core values: ownership, collaboration, agility, dedication to customers and engagement. We
believe that work is more than just a to-do list. You are empowered to build a leading company and to share its success!
We are looking for talented, enthusiastic, and committed people to be a part of our GreenWaves family.
Responsibilities:
Our audio integration framework is based on a software component model, which allows to describe an audio transformation graph in
the form of a set of sources (audio interfaces, memory), nodes (performing the transformations), and destinations (audio interfaces and
memory). The “deployment” of an audio graph consists in executing these processing nodes on different components of the GAP
architecture: the main CPU, the cluster (parallel processor and inference accelerator for neural networks), and the SFU (low latency
audio DSP). This audio framework will be made available to our customers under an Apache-type open-source model.
We are looking for an experienced engineer with a strong background in real-time embedded software and experience of audio
application integration, to reinforce the development of this audio framework. You will in particular contribute to:
● Management of dynamic creation of links between components (bindings)
● Selection/implementation of methods to optimize the life cycle of a component (promotion of constant inputs or not towards
closer memories, etc.)
● Development of real-time execution strategies by combining offline scheduling and online scheduling, taking into account the
real-time constraints of the application
● Assessment of the framework performances on real use cases, and support to end-users
This position requires numerous interactions with the different teams of the company: SDK, audio signal processing, AI applications,
etc.
Required skills:
● Experience in SW integration of real time applications, preferably audio
● Knowledge of scheduling strategies (static, dynamic) with timing deadlines
● Understanding of RTOS and low-level drivers
● Strong team spirit and communication, happy to collaborate and share with his teammates, even remotely
● Work comfortably in an international environment, exchanging by e-mail, telephone or conf-calls
● Good level in English
Desired skills:
● Previous experience in MCU with HW accelerators
● Familiarity with debugging on boards (oscilloscope, logic analyzer, etc.)
● Previous experience in multicore applications
● Previous experience in artificial intelligence
