AI Engineer

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
