Early-Stage / Venture-Backed AI Infrastructure Company

Artificial Intelligence Infrastructure Platform Engineering Developer Tools Enterprise Software B2B SaaS Workflow Automation AI Agents Cloud Infrastructure Integration Platforms

Our client is building an AI-native integration platform that automates mission-critical integrations for companies operating in the physical economy.

The platform uses specialized AI agents to handle the full lifecycle of integrations from understanding requirements through writing testing and deploying integration code into production.

The company is solving a fundamental connectivity problem where businesses still rely heavily on custom integrations that are expensive time-consuming and difficult to maintain.

The team is exceptionally small and highly technical with infrastructure currently owned by the CTO. The company has paying enterprise customers with production integrations and significant demand creating an immediate need for a dedicated infrastructure and platform engineer.

As the first Infrastructure / Platform Engineer youll own the entire infrastructure layer from the ground up working directly with the CTO to build the runtime agent infrastructure observability systems and self-hostable deployment architecture that powers mission-critical enterprise integrations.

This is a highly autonomous individual contributor role where youll establish the technical patterns that future infrastructure engineers will build on while eventually helping recruit and grow the infrastructure team.

This is an opportunity to become the first dedicated infrastructure and platform engineer at a highly technical AI startup and own the foundational infrastructure powering an agentic integration platform.

Youll work directly with the CTO to build the infrastructure layer from the ground up including the integration runtime agent execution environment observability platform deployment systems and self-hostable enterprise architecture.

Rather than inheriting an established infrastructure organization youll define the patterns architecture and engineering standards that future infrastructure engineers will build on.

The role offers unusually broad technical ownership. Youll work across Kubernetes cloud infrastructure distributed systems deployment architecture observability AI agents and enterprise infrastructure while solving problems that directly impact production customers.

Youll also have the opportunity to shape the infrastructure organization itself by helping recruit future engineers and potentially growing into a technical leadership role as the company scales.

If you enjoy greenfield infrastructure Kubernetes cloud architecture AI agents distributed systems high ownership and building foundational systems from scratch this role offers exceptional scope and technical impact.
