About The Position

We're hiring on behalf of A1, an AI product team building the next generation of intelligent productivity applications. Their mission is simple: replace repetitive digital work with AI that can reliably complete real tasks on behalf of users. Rather than building another chatbot, the team is creating long-running AI workflows that manage conversations, coordinate actions, maintain context, and interact with external services—all with minimal user input. As a Backend Engineer, you'll build the systems that make those experiences possible.

Requirements

Strong backend engineering experience in production environments
Experience building high-throughput, low-latency distributed systems
Excellent Python skills (Node.js is a plus)
Hands-on experience deploying and operating services on Kubernetes and Docker
Experience with SQL and NoSQL databases
Familiarity with modern AI infrastructure, including LLM inference, embeddings, or multimodal models
A pragmatic engineering mindset focused on shipping reliable software

Nice To Haves

Experience with OpenAI, Anthropic, or open-source LLMs
Experience building AI orchestration or agent workflows
Knowledge of inference optimization techniques
Experience operating AI services at scale

Responsibilities

Own the backend services that power AI interactions in production, ensuring they remain fast, reliable, and scalable as the platform grows.
Designing and building backend services for AI-powered product features
Developing inference pipelines and orchestration layers around LLMs
Creating reliable APIs used by web, desktop, and mobile applications
Optimizing latency, throughput, caching, batching, and streaming
Building monitoring, logging, alerting, and observability across production services
Debugging distributed systems and improving platform reliability
Working closely with product, infrastructure, and AI engineers to continuously improve performance
