Job Title

What You'll Be Doing

  • Design and prototype agent workflows using LangChain and/or similar frameworks.
  • Develop task automation agents focused on marketing workflows (e.g., campaign execution, reporting, content validation).
  • Build basic RAG pipelines and ReAct agents to improve agent response relevance and accuracy.
  • Benchmark and test LLMs for speed, cost, and fitness to the use case.
  • Work closely with the Hiring Manager to iterate on use cases and validate the POC.

Possible Extensions (Post-POC / Platform Build)

  • Scale agent orchestration using LangGraph, AutoGen, or CrewAI.
  • Containerize workflows and prepare deployment pipelines.
  • Integrate monitoring and observability layers for agent evaluation.

What You Need to Succeed

Must-haves

  • 3+ years of experience in software engineering or machine learning, with at least 1 year of hands-on experience building LLM-based workflows or autonomous agents.
  • Proven ability to design, prototype, and iterate on solutions using LangChain or similar frameworks.
  • Strong understanding of prompt engineering, tool-use chaining, and agent orchestration patterns (e.g., ReAct, Tool-Calling).
  • Practical experience working with vector databases such as Pinecone, FAISS, or Weaviate, and building Retrieval-Augmented Generation (RAG) pipelines.
  • Proficiency in Python and relevant ML libraries (e.g., Transformers, PyTorch, LangChain).
  • Familiarity with Docker and experience deploying ML workloads in cloud environments (AWS, GCP, or Azure).
  • Ability to work independently, communicate effectively with non-technical stakeholders, and iterate rapidly in a PoC-driven environment.

Nice-to-haves

  • Experience with multi-agent frameworks like LangGraph, AutoGen, or CrewAI.
  • Previous work on agentic systems applied to marketing automation or related use cases.
  • Knowledge of CI/CD practices, container orchestration, and performance monitoring for ML pipelines.
  • Awareness of AI ethics, security, and compliance in production-grade applications.
  • Demonstrated contributions to open-source projects, published research, or developer communities in the AI/LLM space.

Benefits

  • Fully remote work arrangement as a contractor.
  • Competitive salary in USD.
  • 10 paid time off (PTO) days per year.
  • 100% company-covered international certifications.
  • Access to coworking spaces.
  • English classes.
  • Engaging team-building activities.
  • Personalized gifts.
  • Welcome kit.
  • Referral programs.
