Description

Founding Software Engineer - Agentic Systems

Location: Tallinn, Spain (Remote), São Paulo

Department: Product Platform #ENG

At Veriff, we are exploring the next frontier of identity verification: agentic AI systems that can reason, act, and operate safely in high-trust environments.

We are forming a small, high-leverage team to explore and productionize agentic capabilities across identity, KYA, risk assessment, and automation workflows.

We are looking for a Founding Engineer to help build this from the ground up.


You’ll help us protect honest people online by:

  • Design and build agentic systems that can:
    • Use tools;
    • Reason across multi-step workflows;
    • Operate under strict compliance and safety constraints.
  • Prototype and productionize LLM-powered workflows;
  • Build internal evaluation frameworks for agent reliability;
  • Define system architecture for scalable, secure AI services;
  • Work closely with product, risk, and compliance teams;
  • Turn ambiguous ideas into working systems.

You are the right future Veriffian for the job if you have:

Strong Systems Engineer

  • 6+ years building backend systems in production
  • Strong Python experience (FastAPI or similar)
  • Experience with distributed systems and async workflows
  • Deep understanding of system design and reliability

Agentic / LLM Experience

Hands on experience building:

  • Tool using agents
  • Multi step reasoning workflows
  • Retrieval Augmented systems (RAG)
  • Multi agent or orchestration systems

Experience with one or more:

  • LangChain / LangGraph
  • OpenAI Assistants or Responses API
  • AutoGen
  • CrewAI
  • Semantic Kernel

You have shipped LLM-powered systems beyond experimentation.

Elements of Our Tech Stack

  • Backend: Node.js (TypeScript), Python, Golang
  • Frontend: React (TypeScript)
  • Mobile: Kotlin (Android), Swift (iOS), Dart (Flutter), TypeScript (React Native)
  • Infrastructure: AWS, Kubernetes, Terraform
  • Data & ML: PostgreSQL, RabbitMQ, Python-based ML models

Nice to have:

  • Experience in fraud, risk, compliance, or identity systems
  • Experience building internal AI evaluation pipelines
  • Familiarity with vector databases (pgvector, Pinecone, etc)
  • Experience operating in regulated environments

What Success Looks Like

  • Reliable agentic workflows running in production
  • Clear evaluation metrics for AI quality and safety
  • Strong architectural foundations for scaling AI capabilities
  • High quality technical documentation and system clarity
