About the job
As a member of our AI research team, you will drive innovation in model compression and efficient deployment for advanced multimodal AI systems, including large language models (LLMs) and vision-language models (VLMs). Your work will focus on reducing model footprint and computational cost while preserving accuracy, enabling high-performance AI to run efficiently across resource-constrained edge devices. You will apply and advance compression techniques such as quantization, knowledge distillation, and pruning to streamline complex multimodal architectures that integrate text, images, and audio.
We expect you to have deep expertise in model compression methods and a strong background in multimodal model architectures. You will adopt a hands-on, research-driven approach to develop, test, and implement novel compression strategies that balance model size, latency, throughput, and accuracy. Your responsibilities include building robust compression pipelines, establishing performance and fidelity metrics, and addressing bottlenecks in production inference. The ultimate goal is to deliver scalable, low-memory, low-latency AI systems on edge devices (i.e., smartphones) that maintain high fidelity and tangible real-world value.
Responsibilities
Break down the key responsibilities in bullet points. It’s helpful to make them actionable and measurable. This could also be grouped into categories for more complex roles.
* Apply low-bit quantization to reduce model size and inference latency for generative AI models (LLMs, VLMs, multimodal) while maintaining accuracy and output quality.

Tips for South African Applicants
Timezone Advantage
South Africa (SAST, UTC+2) overlaps well with European business hours and has a few hours of overlap with US East Coast. Mention your timezone flexibility in your application.
Salary in Context
Even without a listed salary, international remote roles typically pay 2-3x more than equivalent local positions in South Africa due to the exchange rate advantage.
Application Tips
Tailor your CV to international standards — use a clean format, highlight remote work experience, and include your English proficiency. Many SA applicants succeed by emphasising their strong work ethic and cultural adaptability.
Load Shedding Preparedness
If you're applying for a remote role, having a backup power solution (UPS, inverter, or generator) and mobile data as a backup internet connection shows employers you're prepared for South Africa's infrastructure challenges.
