Senior Full-Stack AI Developer

Project Info:

We are launching a mission-critical, AI-powered enterprise automation and decision platform. The system demands advanced LLM orchestration, semantic reasoning, absolute data integrity, and strict compliance with global security standards. As a Senior Full-Stack AI Developer, you will not just integrate APIs; you will own the entire lifecycle of this intelligent platform-from vector database architecture to live production model monitoring.

You will architect resilient backend systems, secure integration plumbing, and seamless deployment workflows for non-deterministic AI applications. This position bypasses traditional organizational handoffs. You build the AI agents, you secure the data pipelines, you deploy the infrastructure, and you run the production loops.

Responsibilities:

• Architect & Implement AI Workflows: Design scalable RAG pipelines and autonomous agent architectures while building lean, high-performance user interfaces for real-time AI interactions.

• Deploy & Optimize Models: Build robust CI/CD pipelines capable of executing zero-downtime schema migrations, token-efficient model caching, and automated fallback procedures when LLM providers experience downtime.

• Harden AI Security: Implement defensive coding practices against prompt injection, enforce strict PII masking before data hits third-party APIs, and secure application-level authentication boundaries.

• Govern AI Output: Serve as a human firewall by conducting rigorous, AI-native code reviews to intercept and fix subtle architectural defects, hallucinated logic, or security flaws introduced by LLM assistance tools.

• Own Reliability & Cost Observability: Track token consumption, monitor semantic drift, author operational runbooks for non-deterministic system behaviors, and lead technical incident responses.

Requirements:

• 8-12+ Years of Experience: Proven track record as a backend-leaning senior engineer who ships complex systems to production. You own the deployment, the security, and the integration plumbing from end to end.

• Production Mindset: Deep expertise in production operations. You are highly capable of handling complex database migrations, architecting zero-downtime deployments, and executing flawless rollback procedures.

• Security Depth: Absolute fluency in OWASP standards and modern defensive practices. You are an expert in secrets management, rigorous input validation, and application-level AuthN/AuthZ.

• AI-Native Code Review Fluency: You deeply understand the unique failure modes that LLMs introduce into codebases and can reliably catch hallucinated logic and AI-generated security vulnerabilities.

• Ownership Without Handoffs: You build it, you run it. You are comfortable carrying the pager, authoring operational runbooks, and leading technical incident response without relying on external DevOps or QA teams.
