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.
