As a Backend Engineer, 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.

Focus
  • Build and operate Back End systems that serve AI-powered features in production.
  • Design inference pipelines, orchestration layers, and service boundaries around models.
  • Own production concerns: monitoring, logging, alerting, and incident response.
  • Optimize latency and throughput across inference, caching, batching, and streaming.
Ideal Experiences
  • Strong Back End 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.
Outcomes
  • Backend systems run reliably at scale, handling production AI traffic with low latency and high throughput.
  • APIs are stable, clear, and support seamless integration with Front End and ML systems.
  • Production incidents are quickly detected, diagnosed, and resolved, minimizing user impact.
  • Iterative improvements based on real usage continuously increase system performance and reliability.
Tech Stack
  • Python
  • NodeJs
  • Pytorch
  • OpenAI/Anthropic/open-source LLMs
  • SQL & noSQL
  • Kubernetes
  • Docker
