Description & Requirements

Who we are looking for
Are you a Python developer ready to go beyond code - to solve real business problems with AI?

Join our international team at Deloitte, where you’ll help design and implement intelligent solutions that drive measurable impact for international clients.

You’ll combine your technical expertise with consulting skills to deliver AI-powered products – from analytics tools to automation and data-driven decision systems.

What You Bring
  • 2–4 years of Python development experience - backend, data, or AI-adjacent work; you write clean, structured, maintainable code
  • Hands-on experience with AI/GenAI concepts - you've worked with LLMs or machine learning models in some capacity and understand how they behave beyond the theory
  • Backend development experience - FastAPI, Flask, or Django; you know how to build and consume APIs properly
  • Solid software engineering fundamentals - Git, REST APIs, testing, and clean code practices are part of your daily workflow, not an afterthought
  • Familiarity with Agile methodologies - Scrum or similar; comfortable working in iterative, collaborative delivery cycles
  • Fluent English - written and spoken; you'll engage with international stakeholders and cross-functional teams
  • Based in Sofia - hybrid presence required
✨ Nice to Have
  • Exposure to multi-agent or LLM orchestration frameworks (LangChain, CrewAI, AutoGen)
  • Experience working with CI/CD pipelines or MLOps concepts
  • Any familiarity with SAP ecosystem (SAP BTP, SAP AI Core) — would be a plus!
  • Industry exposure in HR, Finance, or enterprise SaaS environments 
Your future role
  • Build and deploy AI and GenAI solutions alongside senior engineers and data scientists - from initial PoC through to production 
  • Develop backend services and APIs that connect AI models to real business workflows 
  • Contribute to the development and integration of LLM-based features and multi-agent systems 
  • Support data pipeline development and model deployment processes 
  • Apply CI/CD and MLOps practices in a structured enterprise environment 
  • Collaborate with Product Owners and cross-functional teams to translate business requirements into technical solutions 
  • Grow your expertise in AI engineering within a team that values continuous learning and engineering excellence 
What we offer
  • An opportunity to form and lead a small, dynamic team with a startup approach within a large international company.
  • Flexibility to work from home or from our office in Budapest.
  • Opportunities for professional growth, including mentoring, conferences, training, and certification.
  • A supportive, collaborative, and motivational work environment.
  • Involvement in the development of innovative applications.
  • Full-time role with flexible working hours, ideal for those continuing their studies.
  • A wide range of benefits and the stability of working with a reputable company.
