Job description

Company Profile

We are partnering with Agentic Intelligence (AI) Development Start-up with 100% remote work arrangement. Substantial investment funding from well known Fintech organization and regionally based in Singapore, Malaysia, Hong Kong, UK & USA, currently rebranding and focused on building AI applications for everyday consumers.

The best products today in the world were built by small, world class teams. We are a high talent density and hands-on team. We make decisions collectively, move at rapid speed, striking a balance between shipping high quality work and learning. Joining our team requires the ability to bring structure, exercise judgment, and execute independently. Our goal is to put in hands of our users a truly magical product.

Role

As a Backend Engineer, AI, you own the inference and orchestration layer that powers every AI interaction in the product. Your work sits between models and users, where latency, correctness, reliability, and cost directly impact real-world experience.

You will build and operate production systems that turn model capability into fast, stable, observable APIs used across mobile and desktop clients.

Ideal Experiences

• Strong backend engineering fundamentals in production environments.


• Experience running high-throughput, low-latency services.


• Familiarity with AI inference patterns (LLMs, embeddings, multimodal).


• Comfortable debugging distributed systems under load.


• Bias toward shipping and learning from production behavior.

Tech Stack

• Python


• NodeJs


• Pytorch


• OpenAI / Anthropic / open-source LLMs


• SQl & noSQL


• Kubernetes


• Docker
