Overview

We Are

Wizeline, a global AI-centric technology solutions provider, develops 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, impact. With the right people and the right 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

  • 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.
  • Full Agent Development Life-Cycle : Own scoping, design, implementation, automated evaluation / regression testing, deployment, rollout, monitoring, and iterative tuning.
  • 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.
  • LLM orchestration & planning : Implement multi-model pipelines (e.g., comprehension → planning → critique → response) using frameworks such as OpenAI Function Calling, LangChain / LangGraph, or similar.
  • 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.
  • Continuous Optimisation : Inspect reasoning traces, analyse failure modes, improve prompts / skills / knowledge, and raise autonomous resolution rates week over week.
  • 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

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

    • Nice-to-have

  • Real-time / voice agent delivery (e.g., SSE or WebSockets).
  • Familiarity with emerging multi-agent protocols (MCP, A2A) or supervisor / critique agent patterns.
  • Domain experience in e-commerce, fintech, telecom, or large-scale customer support.
  • 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
