Job description

Duration: 5 months contract (with potential for extension)

Job Overview:

• We are seeking an AI Developer who is a fast learner and rapid problem solver, capable of quickly understanding new domains, technologies, and business problems, and translating them into high-impact proof of concept (PoC) solutions. This role requires the ability to move quickly from idea to working prototype, validate value early, and then guide successful PoCs into scalable, production-ready AI solutions.
• In this role, you will be a hands-on developer - pairing daily with other engineers and guiding the adoption of LLMs, RAG, vector stores, and agentic frameworks. You'll partner closely with product and platform leaders to build AI systems.

What you can expect:

• Work in a highly talented, diverse team.
• Be encouraged to continuously learn new skills, technologies, and tools.
• Identify areas for innovation and have the freedom to rapidly explore and test out your ideas.
• Play a critical role in the design, development, and deployment of AI/ML tools.
• Lead the effort in taking AI/ML solutions from a proof-of-concept to a production-ready state.

An Ideal Candidate Should Demonstrate:

• Deep understanding of machine learning fundamentals and ability to apply them in developing and implementing AI/ML solutions.
• Experience with GenAI technologies and techniques (e.g., RAG, fine-tuning, vector stores, Agentic frameworks).
• Solid grasp of software development principles, including design patterns, testing, and version control such as Git.
• Inquisitive nature, with a deep understanding of both technical and business aspects.
• Data-driven decision maker, combining robust analytical thinking with sound business judgment.
• Excellent communicator with both technical and non-technical team members.
• Comfortable with hands-on involvement in AI/ML experimentation and model development.

Responsibilities Include:

• Participate in projects, demonstrating technical expertise and a hands‑on approach in experimentation and productization.
• Partner with product stakeholders to iterate quickly on PoCs, incorporating feedback and refining solutions in short cycles.
• Establish and socialize strong AI engineering fundamentals, design patterns, and code quality standards.

Technical Skills Needed:

1. Programming & Engineering Excellence

• Python (advanced), APIs, pipelines, and AI orchestration.
• Java/ReactJS (optional).

2. LLM & GenAI Engineering

• Hands‑on experience with commercial LLMs (preferably GPT models).
• Prompting patterns and structured outputs.
• Model evaluation including accuracy/faithfulness checks, hallucination mitigation, and regression testing.
• Safety/guardrails patterns appropriate for enterprise use.
• Strong experience implementing RAG architecture with ingestion pipelines and chunking strategies.
• Vector database / vector search experience with Indexing, similarity search, and metadata filtering.
• Experience with Model Context Protocol (MCP) patterns, standardizing tool/context access for models and agent runtimes.
• Designing MCP servers/tool endpoints and integrating them into LLM apps.
• Experience implementing agentic workflows and A2A patterns such as multi-agent collaboration (planner/executor/reviewer/retriever roles).

3. Code Acceleration (GitHub Copilot)

• Demonstrated ability to leverage GitHub Copilot for rapid scaffolding of code, services, APIs, and development.

4. Data Skills

• SQL + SQL Server, Microsoft Fabric (optional).
• SQL skills including query authoring, joins, and indexing awareness.
• Ability to design data access patterns for AI.

5. Cloud

• MS Clienture Fabric (preferred).

6. Observability & Production Support

• Experience operating and supporting AI-enabled services in production.
• Logging, metrics, tracing (APM tools such as Datadog).
• Model/prompt monitoring, drift signals, and quality regression detection.

Essential Criteria to Apply

• Minimum of 10 years of Python development experience.
• Minimum of 4 years of experience working on AI projects, with a focus on productizing AI/ML solutions.
