Want to know if you're a match for this job?
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.
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.
