**Company:** [AI Fund](https://hotfix.jobs/companies/ai-fund)
**Location:** Mountain View, CA
**Role:** Backend Engineering
**Salary:** $30k – $30k/yr
**Skills:** LLMs, Agentic Architectures, Tool Use, Function Calling, Sql Databases, REST APIs, GraphQL, SSO, Ldap, RBAC, Mcp, Etl Pipelines
**Posted:** 2026-04-17

> Builds AI agent infrastructure for enterprise internal systems, including secure connectors to databases/APIs, natural language task orchestration, authentication layers, and monitoring behind firewalls. Requires strong backend skills, LLM agent experience, and enterprise security knowledge for a 12-week onsite residency.

## Job Description

## What you'll build
- An agent framework that can securely connect to internal databases, REST/GraphQL APIs, and legacy system interfaces behind corporate firewalls.
- A task orchestration layer that lets non-technical operators define multi-step workflows across internal systems using natural language.
- An authentication and access control layer that integrates with enterprise identity providers (SSO, LDAP, RBAC) to enforce existing permission boundaries.
- A monitoring and audit system that logs every agent action for compliance and debugging.

## What you'll do
- Design the core agent architecture for operating in constrained network environments where cloud-first assumptions break down.
- Build connectors for common enterprise data sources: SQL databases, internal APIs, file shares, legacy mainframe interfaces.
- Develop a natural language task definition layer that translates operator intent into safe, auditable multi-step agent actions.
- Implement security primitives: credential vaulting, least-privilege execution, action sandboxing, and rollback capabilities.
- Work with enterprise design partners to validate the agent framework against real internal tooling pain points.

## What you need
- **Strong backend engineering skills**. You have built and shipped production systems that handle real data at real scale.
- **Deep experience** with enterprise infrastructure: databases, APIs, authentication systems, networking constraints.
- **Hands-on experience** building with **LLMs**, particularly agentic architectures, tool use, and function calling.
- Understanding of security and compliance requirements in enterprise environments.
- Ability to work autonomously and make product and architecture decisions without waiting for direction.

## Helpful but not required
- Experience with **MCP (Model Context Protocol)** or similar tool-use frameworks for AI agents.
- Experience building internal developer platforms or internal tooling at scale.
- Background in systems integration, middleware, or ETL pipeline development.
- Founder or founding engineer experience building infrastructure products.

## Compensation
**$10,000/month** for 12 weeks (**$30,000 total**). This is a **contract role** during the residency. If the build leads to a funded company, the next step is a founder-level role with meaningful equity upside.
