As an AI Engineer, you will be the technical engine behind every AI implementation the company runs, setting up the models, building the safety and reliability infrastructure, and establishing the engineering standards that every future AI project will inherit.

This is a greenfield role with high ownership. You will be designing and building the foundational AI platform that Hotwire's business units depend on. You'll partner closely with the Director of AI Implementation and AI Champions embedded in each business unit, translating validated workflow proposals into production-grade AI solutions.

Duties / Responsibilities:

Design and build the core AI platform that connects Hotwire's business applications, data sources, and AI models into reliable, production-grade pipelines
Own the model deployment layer, configure, version, and maintain LLM endpoints across Azure OpenAI and/or AWS Bedrock with environment isolation (dev / staging / prod)
Implement a model abstraction layer (e.g., LiteLLM) to ensure portability across model providers and avoid hard vendor lock-in
Build and maintain an internal AI SDK / shared libraries so that future engineers and CoE projects can bootstrap quickly without reinventing plumbing
Own infrastructure-as-code and CI/CD pipelines for AI services Other duties as required or assigned.
Actively participate in Steering Committee reviews, translating technical risk and feasibility into language business leaders understand
Build and enforce input/output security controls for every AI-facing endpoint:
PII detection and redaction before data reaches external model APIs
Prompt injection detection, pattern-based and embedding-based classifiers
Content policy filtering and output moderation for customer-facing AI surfaces
Role-based access control to AI capabilities across business units
Partner with IT Security and Compliance to ensure every AI deployment meets Hotwire's data residency, encryption, and access audit requirements
Maintain a centralized secrets management approach for API keys, model credentials, and third-party integration tokens
Implement an LLM evaluation framework that every CoE project must pass before production promotion
LLM-as-judge pipelines for automated output quality scoring
Regression test suits that protect against model drift when providers update underlying models
Semantic similarity and coherence metrics for RAG-based applications
Golden dataset management and versioning for reproducible evals
Own the eval harness integration into CI/CD, no model change ships without passing eval thresholds
Track and report quality metrics to the Director and Steering Committee as part of the AI implementation lifecycle
Build operational safety infrastructure around AI services:
Rate limiting and token-budget enforcement per business unit and use case
Circuit breakers to prevent downstream cascades when model APIs degrade
Iteration caps and wall-clock timeouts on agentic workflows
Async queue management and retry logic for high-volume pipelines
Configure private endpoints and VNet integration for model APIs to keep data off public internet paths
Implement cost allocation and spend controls so that per-department AI usage is visible and accountable
Set up comprehensive tracing and monitoring across all AI services using tools such as LangSmith, LangFuse, or equivalent
Build dashboards that surface latency, error rates, token consumption, quality scores, and cost per workflow, visible to both engineering and business stakeholders
Establish alerting thresholds and on-call runbooks for AI service degradation
Maintain audit logs of all model inputs and outputs for compliance review
Serve as the technical reviewer for AI workflow proposals coming from business unit AI Champions before they reach the Steering Committee
Write engineering standards, integration patterns, and runbooks that AI Champions and future engineers can follow
Contribute to vendor evaluations, help assess new AI tooling, model releases, and platform options
Other duties as required or assigned by supervisor.

Minimum Qualifications:

To perform this job successfully, an individual must be able to perform each essential duty satisfactorily. The requirements listed below are representative of the knowledge, skill, and/or ability required.

2-4 years building and operating production LLM applications, not prototypes, not demos, production systems with real users and real SLAs
4 years of software engineering experience with a strong bias toward system design and production-grade architecture
Expert-level Python, you write clean, tested, maintainable Python, not just scripts
Deep understanding of API design, microservices patterns, async programming, and distributed system fundamentals
Hands-on experience with CI/CD pipelines, containerization (Docker), and cloud-native deployment
Strong debugging instincts, you can trace a failure from a user-facing symptom down to a model API edge case
Experience deploying and managing LLMs on enterprise cloud platforms: Azure OpenAI Service or AWS Bedrock
