**Workplace:** remote

**Department:** OP

## Description

🟢 At Dev.Pro, we work on projects that impact millions of people around the world — but we know it’s the people behind the tech who make it all happen. We truly value what makes each person unique and are building a workplace that’s inclusive, friendly, and supportive.

We invite a talented Senior AI Engineer with a genuine passion for AI and curiosity for exploring new technologies to join Dev.Pro. In this role, you’ll build AI solutions end-to-end — from experiments and prototypes to production — for internal teams and incoming projects. You’ll also contribute to the company’s AI growth by sharing knowledge, documenting best practices, and guiding teams in adopting AI.

  
🟩 **What's in it for you:**

-   Tackle complex AI challenges, working hands-on with Python, Node.js, LLM APIs, LangChain, n8n, and vector databases
-   Build end-to-end AI solutions, from early experiments and prototypes to production-ready systems
-   Explore and innovate with the latest AI tools in a collaborative, cross-disciplinary environment

**✅ Is that you?**

-   Power user of modern AI coding tools — agentic and spec-driven workflows
-   Hands-on GenAI experience with LLM APIs, prompt engineering, LangChain, n8n, and AI feature development
-   Testing and evaluation of GenAI systems (LLM evals), with solid code quality as a baseline
-   8+ years in software engineering with strong Python and production backend experience
-   Passion for AI coding demonstrated via side projects, experimentation, and autonomous coding practices
-   Deep understanding of ML fundamentals, including implementing basic models and gradient descent from scratch
-   Strong SQL and practical experience with vector databases and embeddings
-   Able to own initiatives end-to-end and work autonomously
-   Strong analytical thinking and problem-solving skills
-   Expertise in Agile workflows, balancing R&D and delivery priorities
-   Excellent technical communication, documentation, and cross-disciplinary collaboration
-   Upper-Intermediate English level

**Desirable:**

-   Experience in ML tasks (feature engineering, imbalanced datasets, data prep)
-   Hands-on with visual AI workflows, model fine-tuning, agent orchestration, and evaluation
-   Exposure to data engineering (pipelines, transformations, warehouse / lake / lakehouse)
-   Architecture documentation using C4, ADR, or similar decision-capture patterns
-   Experience across JavaScript/Node.js and .NET
-   Cloud & deployment knowledge (any major cloud — AWS, GCP, or Azure)
-   R&D experience (PoCs, demos); client-facing / presales a plus

**🧩Key responsibilities and your contribution**

In this role, you’ll explore and build exciting AI solutions and drive AI adoption and best practices across the company.

-   Design and develop AI solutions end-to-end, from experiments and prototypes to production-ready systems
-   Conduct R&D and build PoCs, exploring new AI tools and methods, testing ideas, and turning validated concepts into working solutions
-   Collaborate with cross-functional teams to design and integrate AI solutions effectively
-   Document solutions, experiments, and best practices to grow AI expertise across the company
-   Advise internal teams on AI adoption, tools, and implementation strategies
