Remote AI Agent Engineer

Tóm tắt công việc
The core product experience runs on an LLM-driven agent that extracts data from client-submitted receipts and documents over WhatsApp, proposes accounting entries, and answers staff questions inside the web app. We're hiring an AI/Agent Engineer to take ownership of this entire layer, making it cheaper, safer and more reliable while closing specific security gaps (prompt injection, unchecked tool authorization) identified in a recent technical audit. You will work alongside a backend-leaning Fullstack Engineer, who owns the surrounding application and infrastructure.
Responsibilities
Own the LLM integration layer used for document extraction (OCR), accounting-entry proposals, and the in-app chat agent, currently built on Anthropic/OpenAI APIs
Implement prompt caching to cut redundant token usage. An identified -83% cost-reduction opportunity and introduce per-tenant usage budgets and quotas
Harden the agent against prompt injection: treat all extracted document text as untrusted input, and require explicit confirmation gates before any tool call that grants data access, creates a contact, or moves money
Replace the agent's currently hard-coded (effectively disabled) permission model with real, enforced per-tool authorization checks
Evaluate and implement model tiering, cheaper models for extraction, stronger models for judgment calls and plan a fallback provider for resilience
Build an evaluation/golden-file test harness so model or prompt changes can be validated before shipping to production
Implement PII redaction before data is sent to third-party LLM providers, and partner with the Fullstack Engineer to log every agent tool call to an audit trail
Advise on data-processing-agreement and data-residency questions for the AI sub-processors (Anthropic, OpenAI), alongside the company's data-protection advisor
Contribute to the n8n-side automation where it touches AI extraction, the document-intake pipeline and coordinating handoffs with the Fullstack Engineer.
