Member of Technical Staff Backend

Inflection AI is a public benefit corporation leveraging our world class large language model to build the first AI platform focused on the needs of the enterprise.

Who we are:

Inflection AI was re-founded in March of 2024 and our leadership team has assembled a team of kind, innovative, and collaborative individuals focused on building enterprise AI solutions. We are an organization passionate about what we are building, enjoy working together and strive to hire people with diverse backgrounds and experience.

Our first product, Pi, provides an empathetic and conversational chatbot. Pi is a public instance of building from our 350B+ frontier model with our sophisticated fine-tuning (10M+ examples), inference, and orchestration platform. We are now focusing on building new systems that directly support the needs of enterprise customers using this same approach.

About the Role

As a backend engineer at Inflection, you will own the platforms, systems, and services that bring our conversational AI to life at scale. You’ll collaborate across research, product, and infrastructure teams to enable rapid iteration, high reliability, and secure delivery of novel AI features to millions of users. Your work will directly impact both the pace of product development and the stability of our production systems.

This is a good role for you if you:

• Have 5+ years of experience building and scaling backend systems for high-throughput applications


• Are fluent in building distributed systems with Python, Go, Rust, or similar languages, and are comfortable with cloud-native architectures (e.g., Kubernetes, gRPC, Postgres, Redis, Kafka)


• Have owned backend services end-to-end—from design and implementation to deployment, monitoring, and debugging


• Thrive in fast-paced environments where you can move quickly without sacrificing engineering rigor


• Proactively improve tooling and infrastructure to support your teammates’ workflows and reliability goals


• Communicate clearly across disciplines and take pride in solving user-facing problems with clean backend solutions

Responsibilities include:

• Design and implement scalable backend systems and APIs that power production LLM experiences, including agentic workflows, memory systems, and tool integrations


• Build and operate high-availability infrastructure to support real-time inference, retrieval, and conversation pipelines


• Develop internal platforms to improve engineering productivity—CI/CD pipelines, service templates, observability frameworks, and rollout tooling


• Collaborate closely with applied research and frontend teams to rapidly prototype, ship, and iterate on end-user features


• Ensure systems meet our high bar for security, uptime, and latency—through incident response, load testing, monitoring, and automation


• Participate in on-call rotations to maintain the reliability of the services you build
