AI Engineer

Vilnius, Lithuania
Remote
€30 – €40 per hour

TLDR

Design and deploy AI agents, integrating OpenAI, Gemini, Anthropic, and open-source models into production software and business processes.

Scale Tech is a software development agency based in Vilnius, Lithuania. We're expanding our AI capabilities and looking for an experienced AI Engineer to join us on a contract basis. If you love turning LLMs into real, production-ready automation, not just prototypes — this could be your next project.

Contract term (B2B) — 1–4 months, full-time. Part-time can also be arranged if that suits you better.
Working method — Remote, must be based in the EU/EEA
Hourly rate — €30–40/hour, depending on experience (open to discussing higher rates for the right candidate)

What you'll do:

  • Design, build, and deploy AI agents that automate real business processes (e.g. generating proposals for client tenders).
  • Integrate LLMs — including OpenAI, Gemini, Anthropic, and open-source models — into existing software products, enabling features like AI chatbots that can act directly within a client's systems and data.
  • Spot automation opportunities and turn them into working solutions.
  • Choose the right LLM/tooling approach for each use case, weighing cost, performance, and reliability.
  • Own delivery end-to-end, from prototype to production.

    • What makes you a great fit:

  • 5+ years of overall software engineering experience.
  • At least 5 successfully delivered AI/LLM projects.
  • Hands-on experience with multiple LLM providers (OpenAI, Gemini, Anthropic) as well as open-source models.
  • Experience building agentic workflows for process automation.
  • Experience integrating LLMs into production software products (chatbots, copilots, or similar AI-powered features).
  • Strong engineering fundamentals and the ability to work independently in a fast-moving, sometimes ambiguous environment.

    • Bonus points:

  • Experience with SaaS products, especially in supply chain, logistics, or other B2B software domains.
  • Familiarity with agent frameworks (LangChain, LlamaIndex, CrewAI, or similar).
  • Experience with prompt engineering or fine-tuning at scale.
  • Prior consulting or contracting experience

    • Ready to build?

    Apply directly here, or send us your CV at hello@scaletech.lt - we'd love to hear about the LLM projects you've shipped.
