0825 - 294LUL | Senior AI Platform Engineer (Python + AWS)

Remote | LATAM | Full-Time

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
  • Strong AWS expertise: Lambda, ECS, SQS, DynamoDB, ElastiCache, Aurora, Redshift
  • 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
  • Excellent communication skills across time zones

Bonus Points For

  • Experience with semantic caching, vector databases, or RAG architectures
  • Familiarity with AI/ML evaluation pipelines and prompt management
  • PHP/Laravel SDK development experience

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.

Apply NOW! Salary starts at $5000/month
