Job description

You thrive on building elegant, high-performance backend systems and data pipelines. You are a Python specialist who loves the language for its simplicity and expressiveness, but you possess an engineer's mindset—viewing code as a craft and architecture as an art. You care deeply about correctness, clean abstraction, and scalability. Whether you are optimizing a FastAPI async endpoint, designing a robust event-driven microservice, or orchestrating a complex data workflow, you take pride in software that is maintainable under the hood and highly reliable in production.

Your Role as a Zenika Consultant:

As a consultant, you’ll work on client engagements. You will design and build robust, scalable backend systems while collaborating closely with client engineering teams to:

• Architect & Build: Design, develop, and maintain high-performance applications and microservices using modern Python frameworks (FastAPI, Django, or Flask)
• Asynchronous & Event-Driven Systems: Implement scalable concurrency patterns and integrate message brokers for real-time data streaming.
• API Excellence: Design clean, contract-first APIs (REST, GraphQL, and/or gRPC) that are a joy for frontend teams and external partners to consume.
• Data Strategy: Implement efficient data access layers and schema designs across relational databases (PostgreSQL, MySQL) and NoSQL solutions.
• Engineering Standards: Apply solid engineering practices including automated testing (PyTest), TDD (Test Driven Development), rigorous code reviews, and living documentation.
• Cloud & Automation: Design and implement automated CI/CD pipelines and deploy cloud-native applications using Docker, Kubernetes, and cloud providers (AWS/GCP/Azuure)
• Leadership: Participate in architectural discussions, advocate for Python best practices, and mentor junior engineers on client teams.

What You Bring

• Experience: 4+ years of professional software development experience with a strong focus on backend engineering.
• Python Mastery: Deep knowledge of Python internals, async programming (asyncio), and writing clean, idiomatic, "Pythonic" code.
• Architectural Depth: Solid understanding of microservices architecture, RESTful design, event-driven patterns, and distributed systems.
• Testing & Quality: A passion for software craftsmanship, clean code (SOLID, DRY), and writing robust test suites using tools like PyTest, Black, and Ruff/Flake8
• DevOps & Containerization: Hands-on experience with Docker and a "you build it, you run it" mentality toward cloud infrastructure and deployment.
• CI/CD: Experience designing, using, or optimizing automated delivery pipelines (e.g., GitHub Actions, GitLab CI)
• Consulting Mindset: Comfort working with diverse clients, explaining complex technical decisions to non-technical stakeholders, and adapting quickly to different team cultures.

• Participate in Zenika tech conferences (TechnoZaures) to learn, share, and grow together
• Dedicated Learning & Development (L&D) budget to support your growth
• Flexible benefits package to cater to your well-being and lifestyle needs
• Comprehensive international medical insurance package
