Company mission
To empower everyone with Artificial General Intelligence (AGI).
Role
Who you are
- Strong C/C++ and Python coding skills
- Deep understanding of GPUs or other accelerators, along with the ability to effectively profile and analyze existing or new kernels
- Experience with CUDA/CUTLASS (and experience with Triton-like compilers is a plus)
- 3+ years of relevant industry experience and experience working with hardware developers
- MS/PhD in Computer Science and Engineering with a specialization in Computer Architecture, Parallel Computing, Compilers or other System
What the job involves
- We’re looking for a seasoned Research Engineer with expertise in GPU computing to design high-performance kernels for our training and inference workloads using CUDA/CUTLASS, C++, and Python
- Using the capabilities of GPUs and other accelerators to the fullest extent to make our custom model architectures fast and efficient for training and inference
- Deliver and maintain high performance GPU and communication kernels that increase utilization and also work well in a distributed training and inference environment
- Collaborating closely with ML Engineers and Researchers to develop new architectures and algorithms that are aware of I/O & Hardware constraints
- Communicating with hardware vendors to advise on design of software or future hardware, while also making sure we are keeping up to date with the cutting edge
- Working on quantization or any form of low-precision arithmetic to increase throughput without degradation in performance
Our take
Search engines have long been a boon to productivity, but a long period of heavy advertising, content and SEO spam and malicious actors have limited the effectiveness of traditional keyword searching. Recently, conversational AI assistants have arrived, allowing non-specialists to navigate an increasingly difficult sea of data and return with relevant information, presented in a usable and sometimes very entertaining way.
Character.ai is one of the more recent entries in this increasingly crowded field that has only grown more heated since the public release of ChatGPT in late 2022. However, compared to Microsoft and OpenAI's offerings, Character.ai stands out with a more playful personality - its bots can mimic the voices of celebrities, historical persons and popular characters. This has led to users spending vastly more time interacting with Character.ai's bots compared to the competition: nearly three times longer on average than with ChatGPT, for instance.
Following a period of rapid user growth, Character.ai closed a major funding round at a valuation exceeding $1 billion. While it is currently enjoying meteoric success, in the longer term, Character.ai's challenge is to develop a funding model that will give it the staying power it needs to compete against OpenAI and other major firms in the market. A solution it is currently exploring is research-based partnerships with large companies such as Musk's xAI and Meta.
