- Experience: Expert
We are looking for an experienced Senior AI/ML Engineer to help design and build a scalable AI platform supporting LLM applications, synthetic data generation, agentic workflows, reinforcement learning environments, and production machine learning operations.
This is a hands-on engineering project for someone who is comfortable working across AI/ML systems, distributed infrastructure, cloud services, APIs, and large-scale data pipelines.
Project Responsibilities
You will help us:
Architect scalable systems for synthetic data generation and automated data labeling
Build agentic and multi-agent workflows that can reason, take actions, and improve through evaluation
Design APIs, backend services, orchestration layers, and compute infrastructure
Develop LLM training, evaluation, and inference pipelines
Create benchmarks, datasets, simulation environments, and automated evaluation frameworks
Provision reinforcement learning environments for AI agents
Build reliable data pipelines for collecting, transforming, validating, and processing large datasets
Optimize LLM workloads for performance, reliability, scalability, and cost
Deploy AI services across AWS, GCP, Azure, or hybrid cloud environments
Implement monitoring, telemetry, logging, alerting, and production debugging processes
Collaborate with our team on architecture decisions, technical planning, and implementation
Required Experience
5+ years of professional software engineering experience
Strong Python development experience
Experience building production AI/ML platforms or cloud-native software systems
Hands-on experience with one or more of the following:
LLM applications and infrastructure
Agentic or multi-agent workflows
Synthetic data generation
MLOps and model platforms
Training and inference infrastructure
Machine learning pipelines
Workflow orchestration
Large-scale data processing
Experience with distributed systems and cloud infrastructure
Experience with AWS, GCP, or Azure
Strong understanding of APIs, microservices, databases, queues, and asynchronous processing
Experience with monitoring, observability, reliability, performance optimization, and production incident debugging
Ability to write clean, maintainable, tested, and well-documented code
Preferred Technologies
Experience with several of the following would be valuable:
Python
FastAPI, Flask, or Django
PyTorch, TensorFlow, Hugging Face, or similar ML frameworks
OpenAI, Anthropic, Gemini, or open-source LLM APIs
LangChain, LangGraph, LlamaIndex, AutoGen, CrewAI, or similar agent frameworks
Kubernetes and Docker
AWS, GCP, or Azure
Apache Spark, Ray, Kafka, or distributed computing frameworks
Airflow, Dagster, Prefect, Argo Workflows, or similar orchestration tools
PostgreSQL, MongoDB, Redis, or vector databases
MLflow, Weights & Biases, or similar experiment-tracking platforms
Terraform and CI/CD tools
Reinforcement learning and simulation frameworks
Expected Deliverables
Depending on your experience and the project phase, deliverables may include:
AI platform architecture and technical design documentation
Production-ready Python services and APIs
Synthetic data generation pipelines
Agentic workflow and multi-agent orchestration systems
LLM evaluation and benchmarking infrastructure
Training, inference, and reinforcement learning environments
Cloud deployment and infrastructure automation
Monitoring, logging, testing, and operational documentation
Ideal Freelancer
The ideal candidate has previously built or supported production AI systems—not only prototypes or notebooks. You should be able to make practical architecture decisions, communicate technical tradeoffs, work independently, and deliver reliable software for real users.
Experience working with high-growth startups, enterprise AI products, or large customer-facing platforms is a strong advantage.
