Job description

Let’s talk skills and passion first.

Is there a Zenika in you?

Let’s talk skills and passion first.

You thrive at the intersection of high-performance backend systems and modern frontend development. You are a polyglot at heart—someone who views programming languages as tools to solve specific problems rather than identities. You care deeply about simplicity, correctness, and scalability, and you enjoy designing systems that are elegant under the hood and intuitive for users. Whether it’s optimizing a Java microservice, scripting a data pipeline in Python, or crafting a slick UI in React, you take pride in well-crafted software.

Your Role As a Zenika Consultant

• Architect & Build: Design and maintain full stack applications using a variety of modern frameworks (ts/js, Node.js, Python, or Go).
• Frontend Craftsmanship: Build responsive, modular user interfaces using React and TypeScript.
• API Excellence: Design clean, contract-first APIs (REST, GraphQL, and/or gRPC).
• Data Strategy: Implement efficient data access layers across SQL and NoSQL databases.
• Engineering Standards: Apply solid engineering practices including TDD (Test Driven Development), rigorous code reviews, and living documentation.
• Cloud & Automation: Design and implement automated CI/CD pipelines and deploy applications using Docker, Kubernetes, and cloud-native providers (AWS/GCP/Azure).
• Leadership: Participate in architectural discussions and mentor junior engineers within client teams.

What You Bring

• Experience: 5+ years of professional software development experience in a full stack capacity.
• Polyglot Mindset: Strong proficiency in at most two major backend ecosystems (e.g. Python, Node.js/TypeScript, or Golang).
• Frontend Mastery: Deep practical experience building production-grade UIs with React (State management, Hooks, and TypeScript).
• Architectural Depth: Solid understanding of microservices architecture, event-driven design, and concurrency patterns.
• DevOps & Containerization: Hands-on experience with Docker and a "you build it, you run it" mentality toward cloud infrastructure.
• CI/CD: Experience designing or optimizing automated delivery pipelines.
• Software Craftsmanship: A passion for clean code (SOLID, DRY) and a collaborative mindset.
• Consulting Mindset: Comfort working with diverse clients, explaining complex technical decisions to stakeholders, and adapting to different team cultures.
