Descripción del empleo

Staff AI Engineer

We are: Wizeline, a global AI-centric technology solutions provider, developing cutting-edge, AI-powered digital products and platforms.

We partner with clients to leverage data and AI, accelerating market entry and driving business transformation.

As a global community of innovators, we foster a culture of growth, collaboration, and impact. With the right people and ideas, there's no limit to what we can achieve. Are you a fit? Sounds awesome, right?

Now, let's make sure you're a good fit for the role.

Key Responsibilities

1. Agent design & delivery: Translate business goals into deterministic, guard-railed conversational workflows; ship agents that handle millions of user interactions with high CSAT and low latency.
2. Full Agent Development Life-Cycle: Own scoping, design, implementation, automated evaluation/regression testing, deployment, rollout, monitoring, and iterative tuning.
3. Tool & data integration: Connect agents to enterprise APIs, vector/RAG knowledge bases, event streams, and internal micro-services so they can act, not just chat.
4. LLM orchestration & planning: Implement multi-model pipelines (e.g., comprehension, planning, critique, response) using frameworks such as OpenAI Function Calling, LangChain/LangGraph, or similar.
5. Trust, safety, and compliance: Implement multi-layer guardrails (rules + supervisor models), PII detection/masking, credential vaulting, and auditable traces that satisfy SOC 2 / GDPR-class requirements.
6. Continuous Optimization: Inspect reasoning traces, analyze failure modes, improve prompts/skills/knowledge, and increase autonomous resolution rates week over week.
7. Cross-functional collaboration: Work closely with client PMs, CX leaders, and non-technical stakeholders; explain AI trade-offs clearly and gather feedback to shape roadmaps.

Must-have Skills

1. 5+ years of software engineering experience in production environments (TypeScript/Node, Go, or Python) with strong API design, testing, and debugging habits.
2. Hands-on LLM experience (GPT, Claude, Gemini, or fine-tuned OSS models): prompt engineering, function/tool calling, model selection, evaluation.
3. Retrieval-Augmented Generation (RAG): designing embedding pipelines and semantic search with Pinecone, Weaviate, etc.
4. Agent orchestration expertise: LangChain/LangGraph, OpenAI Agents SDK, CrewAI, or equivalent frameworks for tool-augmented reasoning loops.
5. ML-/DevOps literacy: containerization, CI/CD, GPU/AI infra, caching, automated evals for nondeterministic systems.
6. Experience enforcing security guardrails & PII protection in user-facing AI products.

Nice-to-have

1. Real-time/voice agent delivery (e.g., SSE or WebSockets).
2. Familiarity with emerging multi-agent protocols (MCP, A2A) or supervisor/critique agent patterns.
3. Domain experience in e-commerce, fintech, telecom, or large-scale customer support.
4. Prior work with automated prompt/agent regression testing frameworks.

What we offer

• Competitive compensation & total rewards
• Health benefits & wellness programs
• Savings & retirement plans
• Global mobility opportunities
• Flexible work policy and remote-friendly approach
• Happy hours, gaming tournaments, sports activities & more
