AI/Machine Learning Engineer

Machine Learning Engineer - Build AI Products for Global Tech Companies

Location: Chisinau, Moldova (Hybrid/Remote options available)
Experience: 3-7 years
Engagement: Full-time, Dedicated Team Member

The Opportunity

Join FulmenFlux and work directly with Silicon Valley startups and scale-ups as their dedicated ML Engineer. You’ll be embedded in their teams, building cutting-edge AI products that reach millions of users—without the visa hassles or relocation stress.

What You’ll Do

Core ML/DL Development

• Design and implement production-ready machine learning pipelines using Python
• Build and optimize deep learning models for real-world applications (computer vision, NLP, recommendation systems)
• Deploy models at scale using modern MLOps practices and cloud infrastructure

LLM Engineering

• Fine-tune large language models (GPT, LLaMA, Mistral, BERT variants) for domain-specific applications
• Implement RAG (Retrieval-Augmented Generation) systems and vector databases
• Optimize inference costs and latency for production LLM deployments
• Build evaluation frameworks for LLM performance and safety

Technical Leadership

• Collaborate directly with client engineering teams via Slack, GitHub, and video calls
• Participate in architecture decisions and technical roadmap planning
• Mentor junior engineers and conduct code reviews
• Present findings and recommendations to technical and non-technical stakeholders

Technical Requirements

Must-Have Skills:

• Python Mastery: 3+ years writing production Python code, with deep understanding of asyncio, type hints, and modern Python patterns
• ML Frameworks: PyTorch or TensorFlow/Keras (ideally both), including custom layer implementation and distributed training
• Modern ML Stack:
  • Transformers library (Hugging Face ecosystem)
  • scikit-learn, XGBoost, LightGBM, PyTorch, TensorFlow/Keras
  • pandas, numpy, scipy for data manipulation
  • Weights & Biases, MLflow, or similar for experiment tracking
• LLM Experience: Hands-on experience with at least one of:
  • Fine-tuning models using LoRA, QLoRA, or full fine-tuning
  • Prompt engineering and chain-of-thought implementations
  • LangChain, LlamaIndex, or similar frameworks
  • OpenAI API, Anthropic API, or open-source model deployment

Nice-to-Have Skills:

• Experience with vector databases (Pinecone, Weaviate, Qdrant, Chroma)
• ONNX, TensorRT, or other model optimization frameworks
• Distributed computing (Ray, Dask, Apache Spark)
• Cloud ML platforms (AWS SageMaker, GCP Vertex AI, Azure ML)
• Container orchestration (Docker, Kubernetes)
• Academic background (MS/PhD) in ML/AI/CS/Mathematics

What Makes You Successful

• Production Mindset: You don’t just train models—you ship them. You understand the difference between Kaggle notebooks and production ML systems.
• Communication Excellence: Your English is fluent, and you can explain complex ML concepts to both engineers and product managers.
• Self-Directed Learning: The field moves fast. You’re already experimenting with the latest papers and models before they become mainstream.
• Business Acumen: You understand that the best model is the one that solves real business problems, not the one with the highest accuracy.

Soft Skills We Value

• Fluent English (written and spoken) - you’ll communicate daily with international teams
• Strong problem-solving abilities and analytical thinking
• Self-motivated with excellent time management
• Comfortable with asynchronous communication
• Ability to explain complex technical concepts clearly
• Proactive approach to learning new technologies

What We Offer

Competitive Compensation:

• Performance bonuses tied to client satisfaction
• Annual salary reviews

Growth & Development:

• Work on diverse projects with cutting-edge technologies
• Access to learning platforms and certification programs
• Mentorship from senior architects
• Clear career progression path

Work-Life Balance:

• Flexible working hours (core hours: 2 PM - 6 PM to overlap with European/US clients)
• Hybrid work model - choose between office collaboration or remote flexibility
• 21 days paid vacation + Moldovan public holidays
• Sick leave and personal days

Additional Benefits:

• Premium health insurance
• Modern office in central Chisinau with ergonomic workstations
• Latest MacBook Pro or equivalent
• Team events and knowledge-sharing sessions
• Relocation assistance for candidates outside Chisinau
