Senior AI Engineer

About the Position

Teamvoy is an AI engineering company specializing in production AI for fintech, healthcare, insurance, and manufacturing. Founded in 2013, we take full ownership of delivery - architecture, implementation, compliance, and long-term support - with senior engineers on every engagement. We hire people who want hard problems with real stakes: KYC automation, clinical data pipelines, core banking AI, and claims processing. The work ships to production. The engineers stay accountable for it. If that's the kind of role you're looking for, we're hiring.

We are looking for a Senior AI Engineer to join our team and help design, build, and scale modern AI-powered applications and backend systems for international clients.

Responsibilities

• Build new applications and backend services using an AI agent-driven workflow (Claude Code, Codex, Cursor, MCP-based setups)
• Direct and review work produced by AI coding agents - specs, plans, diffs, tests
• Design AI-powered features: RAG, prompt orchestration, structured outputs, function calling
• Architect agent-friendly codebases - clear contracts, testability, modular services
• Instrument observability, monitoring, and debugging across services and AI workflows
• Apply AI safety practices, prompt-injection defenses
• Optimize cost, latency, and inference performance
• Partner with Product, Design, and Engineering on discovery and delivery

Requirements

• 5+ years in commercial software engineering, strong Python/JAVA/RoR backend
• 2+ years building production LLM-powered applications
• Daily, high-output use of AI coding agents (Claude Code, Codex, Cursor, or similar)
• Working knowledge of agent orchestration frameworks (LangChain, LangGraph, CrewAI, Pydantic AI, MCP) - enough to design with them, even if you don't operate them daily
• Modern LLMs (Claude, GPT, Gemini), prompt engineering, structured outputs, function calling
• Production RAG and vector DBs (pgvector, Pinecone, Weaviate, Chroma)
• Software architecture: APIs, async, queues, distributed systems
• Cloud (AWS, Azure, or GCP) and cloud AI (Bedrock, Azure OpenAI, Vertex AI)
• LLM observability (LangSmith, Langfuse, Arize, Helicone, OpenTelemetry)
• Upper-Intermediate+ English level; Native-level Ukrainian language

Nice to Have

• Building custom MCP servers or agent tool integrations
• Fine-tuning open-source models
• TypeScript
• Semantic cac

We Offer

• Great company atmosphere and open communication
• 20 working days of vacation and 20 sick days
• Development support
• Financial support for learning and sports
• Accounting support
• Membership in Lviv IT Cluster

We actively support the Ukrainian Armed Forces and local humanitarian initiatives as part of our company mission.
