AI Platform & Integration Engineer
We are building an enterprise intelligence layer that connects data, AI models, business systems, reasoning, workflows, and user experiences.
We are seeking an AI Platform & Integration Engineer to build the infrastructure behind intelligent enterprise applications.
This person will focus less on visual frontend development and more heavily on AI architecture, model orchestration, APIs, data connectivity, enterprise integrations, reliability, security, and production AI systems.
What You’ll Own
Design and implement multi-model AI infrastructure
Integrate and manage model access through OpenRouter and direct model-provider APIs
Build intelligent model routing based on task, latency, cost, privacy, reliability, and capability
Implement model fallbacks and resiliency strategies
Build AI tool/function-calling systems
Develop agentic and multi-step workflow architectures
Connect AI systems securely to enterprise databases, APIs, SaaS platforms, CMS environments, search tools, CRMs, and proprietary systems
Build RAG and enterprise knowledge-retrieval systems
Implement semantic search and entity resolution
Design contextual and long-term application memory
Build enterprise data pipelines and ingestion services
Normalize and reconcile fragmented data
Develop secure data-access layers for AI
Implement permissions and policy enforcement outside the model
Establish observability for AI requests, costs, latency, tool calls, failures, and model performance
Build evaluation frameworks for accuracy and reliability
Optimize inference cost and performance
Support private, hybrid, cloud-agnostic, or client-specific deployments
Collaborate with Solution Architects to turn future-state designs into working infrastructure
Support Full-Stack Engineers consuming the AI and data services you create
AI Experience We Want
Deep experience with several of the following:
OpenRouter
OpenAI
Anthropic
Google Gemini
Open-source models
Multi-model orchestration
Tool/function calling
Structured outputs
Agent architectures
RAG
Embeddings
Semantic retrieval
Vector databases
Model routing
Model evaluation
Guardrails
Context management
Prompt engineering
AI observability
Inference optimization
Experience with technologies such as:
LangGraph
LlamaIndex
LangChain
LiteLLM
MCP / Model Context Protocol
Vercel AI SDK
pgvector
Pinecone
Weaviate
Qdrant
is valuable.
We are not looking for someone who relies exclusively on one framework or one model provider.
Data & Integration Experience
Strong experience with:
Python
TypeScript / Node.js
PostgreSQL
SQL
Redis
REST APIs
Webhooks
Authentication
OAuth
API gateways
Data pipelines
ETL/ELT
Data normalization
Entity resolution
Data quality
Event-driven systems
You should be comfortable being handed multiple databases and APIs that were never designed to work together and developing a clean, secure integration architecture.
Architecture Philosophy
We expect you to understand that an LLM should not control everything.
You should know how to determine when to use:
Deterministic business rules
Traditional algorithms
Search
Database queries
Machine learning
Knowledge graphs
Vector retrieval
LLM reasoning
External tools
Human approval
Our goal is reliable enterprise intelligence—not AI theater.
Security & Enterprise Readiness
You should understand:
Data minimization
Role- and attribute-based access
Tenant isolation
Encryption
Secrets management
Auditability
PII handling
Model-provider data policies
Prompt injection risks
Tool permissions
Least-privilege access
Production monitoring
Failure recovery
How We Work
This is a high-accountability environment.
We expect:
Proactive communication
Dependability
Ownership
Clear documentation
Early escalation of blockers
Thoughtful technical pushback
Respect for scheduled meetings and commitments
Independence without isolation
If something changes, communicate.
If you see a problem, raise it.
If you own something, drive it.
Ideal Candidate
You likely have:
5+ years of software, backend, platform, ML, AI or data-engineering experience
Significant hands-on experience with production generative AI systems
Experience integrating complex enterprise environments
Strong Python skills
Strong API and data architecture experience
Experience with multiple model providers
Production deployment experience
Excellent troubleshooting skills
The ability to explain technical decisions to nontechnical stakeholders
Engagement: Contract, with potential to expand based on performance and company needs.
Candidates should be prepared to demonstrate previous systems they have personally built and may participate in a live technical architecture exercise.
