🌍 About Qatium
Qatium is the AI Water Platform for utility operations. We help utilities visualise their networks, simulate decisions, and optimise performance — tackling one of the world’s most urgent challenges: up to 50% of clean water is lost before it reaches the tap.
By bringing network data, modelling and operational insights into an intuitive digital environment, Qatium helps more people across a utility understand what is happening in their network and make better-informed decisions.
Today, Qatium works with utilities across 17 countries and 6 continents, helping water teams at different levels of digital maturity improve how they understand and manage their networks. 💧

Backend Engineering & Architecture
Build and evolve backend services, APIs, and integrations, making pragmatic technical decisions that improve scalability, reliability, and maintainability.
Engineering Quality & Security
Deliver secure, well-tested, production-ready software, proactively identifying risks, improving existing solutions, and ensuring long-term quality.
Product Thinking & Problem-Solving
Collaborate with Product and Design to understand customer needs, challenge assumptions, and turn complex problems into simple, effective solutions.
Continuous Improvement & AI-Assisted Development
Improve engineering practices through collaboration, code reviews, and knowledge sharing, leveraging AI-powered tools to accelerate development while maintaining high standards of quality and security.
💡 What We're Looking For
Core requirements
Full-stack engineering experience: Proven experience building and delivering production web applications, with the ability to work confidently across frontend and backend systems.
Modern frontend development: Strong knowledge of TypeScript and experience with a modern frontend framework such as React, Vue.js, or equivalent.
Backend development: Solid experience with at least one backend language, such as Python, Go, or Node.js, including API design and relational databases.
Production engineering: Hands-on experience with Git, CI/CD pipelines, containers, deployment workflows, and application monitoring.
Ownership & autonomy: A track record of independently delivering features or solving complex technical challenges, even when requirements are not fully defined.
Engineering judgement: Ability to balance speed, simplicity, security, performance, and long-term maintainability.
Product mindset: Genuine interest in understanding user problems and delivering solutions that create real customer value.
English proficiency: Strong written and spoken English, comfortable working in an international team.
It's a plus if you have
Experience with cloud environments such as AWS or Azure, Kubernetes, or GitOps.
Familiarity with event-driven architectures and messaging systems such as NATS, Kafka, or Pub/Sub.
Experience with authentication and authorisation technologies, including SSO, SAML, or secrets management.
Background in data-intensive applications, IoT, digital infrastructure, or water utilities.
🌱 Why Qatium?
At Qatium, you'll work on technology that addresses a real-world challenge: making water management smarter and more efficient.
You'll be part of a small, collaborative team where your ideas matter, your contributions have a direct impact on the product, and autonomy is part of how we work. You'll also have access to learning budgets, language-learning platforms, and flexible compensation options.
Above all, we value curiosity, diverse perspectives, and people who enjoy building meaningful things together 💧
