Are you passionate about AI? 🤖
At Satori Analytics, we aim to change the world one algorithm at a time by bringing clarity to global brands through Data & AI. From cloud-based ecosystems for fintech to predictive models for airlines, our cutting-edge solutions cover the entire data lifecycle—from ingestion to AI applications.
As a fast-growing scale-up, our team of 100+ tech specialists—including Data Engineers, Data Scientists, and more—delivers innovative analytics solutions across industries like FMCG, retail, manufacturing and FSI. Join us as we lead the data revolution in South-Eastern Europe and beyond!
We are looking for a Senior AI Engineer who can bridge the gap between modern Generative AI capabilities and robust Software Engineering. You will design and build scalable AI-powered applications, work with Large Language Models and agentic systems, and help turn rapidly evolving GenAI technologies into reliable, maintainable products.
What Your Day Might Look Like:
- Build production-grade GenAI applications: Design and develop AI-powered services and applications using Python, LLMs and modern software engineering practices—from prototypes to scalable production systems.
- Engineer intelligent workflows: Build RAG pipelines, AI agents, tool-calling workflows, structured generation, conversational systems and other LLM-powered capabilities that solve real business problems.
- Own the software behind the AI: Develop clean, modular and testable backend services, APIs and integrations, ensuring AI solutions are scalable, maintainable and production-ready.
- Design AI architectures: Make architectural decisions around model selection, orchestration, retrieval, APIs, caching, data stores, vector databases and cloud infrastructure.
- Make AI reliable: Implement evaluation frameworks, observability, tracing, monitoring and guardrails to understand how AI systems behave and continuously improve their quality.
- Optimize performance: Improve latency, throughput, reliability and cost across LLM-powered applications through model routing, caching, asynchronous processing and thoughtful system design.
- Integrate the AI ecosystem: Work with foundation models and platforms from providers such as OpenAI, Anthropic, Google, Microsoft and open-source ecosystems.
- Collaborate across disciplines: Work closely with Software Engineers, Data Engineers, Data Scientists, Product teams and domain experts to translate business requirements into effective AI products.
- Lead technically: Guide engineering decisions, review designs and code, mentor other engineers and establish best practices for building GenAI applications.
- Stay ahead: Explore emerging GenAI technologies, frameworks and architectural patterns and assess where they can create meaningful value rather than adopting technology for technology's sake.
- Document and share: Create clear technical documentation, architectural decisions and reusable patterns that help the broader team build better AI systems.
