Python Engineer

About the Position

At Luxoft, we are pioneering the next generation of Agentic AI systems. We are seeking an exceptional Backend Engineer to architect the core infrastructure for software that doesn't just execute commands, but reasons, plans, and acts autonomously. As a key member of our elite AI Core team, you will move beyond traditional backend development to build the central nervous system for our AI agents. This role is for a true systems builder-someone passionate about creating robust, scalable, and intelligent platforms that empower autonomous AI to solve complex, real-world problems.

Responsibilities

• Architect & Develop: Design, build, and maintain high-performance backend services in Python, using FastAPI for our core agentic platform.
• Model Reality: Implement complex data validation and serialization schemas with Pydantic to ensure data integrity across our distributed systems.
• Empower Agents: Develop the core logic for AI agents, including tool integration, state management, and multi-step reasoning frameworks.
• Manage Data Persistence: Design, optimize, and manage PostgreSQL databases. Write efficient SQL queries, manage migrations, and ensure the long-term health and scalability of our data stores.
• Containerize & Deploy: Create and maintain clean, efficient Dockerfiles and Docker Compose configurations for all backend services, streamlining our deployment pipelines.
• Collaborate & Innovate: Work in close partnership with AI Researchers, Prompt Engineers, and Frontend Developers to deliver cohesive, end-to-end intelligent solutions.
• Test & Harden: Author comprehensive unit and integration tests to guarantee the reliability and robustness of the foundational systems powering our agents.

Requirements

Must Have

• Technical Excellence:
  • Proven Professional Experience: A minimum of 3 years in backend engineering, with a strong portfolio of building scalable, production-grade systems using robust Python skills. This includes deep, hands-on experience with database management.
  • Deep expertise in FastAPI and a strong appreciation for its asynchronous capabilities. Utilizing Rust programming language is highly valuable.
  • Mastery of Pydantic for creating strict, type-safe data models that enforce architectural clarity.
  • Experience in any common agentic frameworks such as langGraph, Pydantic-AI, Google ADK, Agno, or any similar framework.
  • Strong command of PostgreSQL, including advanced schema design, query optimization, and indexing strategies.
  • Production-level experience with Docker, with a proven ability to write clean, multi-stage Dockerfiles and manage containerized applications.
• The Agentic Mindset:
  • A profound passion for AI and a demonstrable interest in agentic systems. You have likely experimented with frameworks like LangChain, LlamaIndex, or AutoGen, or you possess a strong desire to build such systems from fundamental principles.
  • A systems-thinking approach. You can visualize how disparate components-LLMs, databases, APIs, and tools-integrate to form a single, intelligent entity.
• Personal Attributes:
  • Insatiable Curiosity: You are constantly learning and exploring the bleeding edge of AI and software engineering.
  • Ownership Mentality: You don't just write code; you take ownership of the systems you build and are accountable for their performance and reliability.
  • Collaborative Spirit: You thrive in a team environment, sharing knowledge and elevating those around you.

Nice to Have

• Experience with vector databases (e.g., Pinecone, Chroma, Weaviate).
• Knowledge of cloud platforms (AWS, GCP, Azure) and infrastructure-as-code (Terraform).
• Familiarity with CI/CD pipelines (e.g., GitHub Actions, GitLab CI).
• Experience with message queues (e.g., RabbitMQ, Kafka) for asynchronous task processing.

We Offer

• Competitive salary
• Opportunity to work in a cutting-edge field of AI and software engineering
• Collaborative and innovative work environment
• Professional development opportunities
