About
One of TalentCross's most innovative and high-impact clients is hiring a
Senior AI Platform Engineer
to help build the backbone of their AI infrastructure. This is a rare opportunity to work with a fast-scaling SaaS company that's transforming a legacy industry with cutting-edge technology and a global-first mindset.
What You'll Be Doing You'll lead the design and delivery of a mission-critical AI platform layer that powers all products across the company. This includes:
Building cloud-native APIs in Python (FastAPI) on AWS (API Gateway, Lambda, ECS Fargate)
Defining OpenAPI 3.1 specs and generating SDKs (PHP, JS) for seamless integration
Optimizing performance with caching, idempotency, rate limiting, and request deduplication
Engineering fault-tolerant systems with circuit breakers and policy-based routing
Implementing observability dashboards using CloudWatch and Datadog
Orchestrating async jobs via SQS, Step Functions, and EventBridge
Collaborating with product teams to ensure smooth developer experience
Driving cost and model quality optimization initiatives
What You Bring
5+ years backend development experience
3+ years with Python (FastAPI preferred), async programming, and streaming
2+ years working with distributed/cloud-native systems
Proven experience designing REST APIs with OpenAPI 3.1
Familiarity with LLM platforms (Amazon Bedrock, OpenAI, Gemini, etc.)
Solid understanding of security best practices and CI/CD workflows
Bonus Points For
Experience with semantic caching, vector databases, or RAG architectures
Familiarity with AI/ML evaluation pipelines and prompt management
Why This Role Stands Out You'll be building the central nervous system for all AI-powered features—high visibility, high impact, and a mandate to deliver reliability, performance, and security at scale. The team is remote-first, globally distributed, and deeply committed to innovation.
