We are seeking a seasoned Senior Full-Stack Python Engineer with 5+ years of experience to design, build, and scale robust web applications. In addition to core full-stack capabilities, you will help us bridge the gap between traditional software engineering and next-generation AI features.
The ideal candidate is a Python expert who is comfortable architecting scalable backends, building intuitive frontends, and has a foundational, working knowledge of Generative AI (e.g., integrating LLMs, prompt engineering, or using AI APIs) to help us inject smart capabilities into our product ecosystem.
Key Responsibilities
Backend Development: Design, develop, and maintain robust, scalable, and secure server-side logic using Python frameworks (FastAPI, Django, or Flask).
Frontend Integration: Create highly responsive, user-friendly UI components using modern JavaScript frameworks (React.js, Vue.js, or Angular).
GenAI Implementation: Integrate Generative AI capabilities into existing workflows, utilizing LLM APIs (OpenAI, Anthropic, or AWS Bedrock), managing prompt design, and working with vector databases for basic RAG (Retrieval-Augmented Generation) setups.
Database & Architecture: Design optimal database schemas (SQL/NoSQL), write efficient queries, and implement caching layers to ensure low-latency application performance.
CI/CD & Cloud: Deploy and manage applications within cloud environments (AWS/GCP/Azure), containerizing applications using Docker, and maintaining automated deployment pipelines.
Mentorship & Best Practices: Lead code reviews, enforce clean architectural patterns, write comprehensive unit/integration tests, and mentor junior-to-mid-level engineers.
Must-Have Skills
Deep expertise in at least one major Python web framework (preferably FastAPI or Django).
Strong understanding of asynchronous programming in Python (asyncio) and building RESTful or GraphQL APIs.
Strong proficiency in JavaScript/TypeScript and hands-on production experience with React.js, Vue.js, or Next.js.
Solid understanding of state management (Redux, Context API, Vuex) and modern CSS styling frameworks (Tailwind CSS, Styled Components).
Practical experience consuming LLM APIs and designing effective system prompts.
Proficiency with relational databases (PostgreSQL, MySQL) and NoSQL solutions (MongoDB, Redis).
Solid experience with Docker and cloud services (specifically AWS services like EC2, Lambda, or ECS).
Experience with Git and modern CI/CD tools (GitHub Actions, GitLab CI).
Nice to Have
Familiarity with orchestration frameworks like LangChain or LlamaIndex is a strong plus.
Basic understanding of vector embeddings and vector databases (e.g., Pinecone, Chroma, pgvector).
Familiarity with Groovy scripting, especially in Jenkins pipelines.
Soft Skills
Strong analytical and problem-solving skills.
Excellent communication and teamwork abilities.
Self-motivated with a passion for quality, learning, and innovation.
At KONE, we are focused on creating an innovative and collaborative working culture where we value the contribution of each individual. Employee engagement is a key focus area for us and we encourage participation and the sharing of information and ideas. Sustainability is an integral part of our culture and the daily practice.
