Job description

Leadtech Group builds and scales digital products used by millions of people worldwide. With over 18 years of experience, we bring together multidisciplinary teams to turn ideas into meaningful, high-impact solutions.

Within the group, MAU by Leadtech focuses on subscription-based apps and digital products. It builds on the expertise, technology and product mindset developed at Leadtech, combining proven experience with a strong focus on user value and long‑term growth.

Across both brands, we share the same approach: a deep commitment to understanding people and creating experiences that make a difference — for our users and for our teams.

We work as a remote‑first, international team, where flexibility and collaboration shape how we build, learn and move forward together. Our environment brings together experienced professionals across product, tech, data and design, all driven by curiosity, ownership and continuous improvement.

If you’re looking to contribute to products with real impact and grow alongside a team that values how things are built as much as what is built, we’d love to meet you.

If you're a highly motivated person with a real interest in tech and a passion for building cutting‑edge products, we've got the perfect job for you!

Key Responsibilities

• Design, implement, and maintain scalable and reliable cloud infrastructure for the backend services developed, leveraging modern practices such as Infrastructure as Code
• Implement and refine monitoring, logging, and alerting strategies using GCP's native tools and other relevant solutions
• Design, implement, and maintain Continuous Integration and Continuous Deployment (CI/CD) pipelines
• Collaborate closely with mobile, web and backend development teams to define and implement best practices for deployment, performance optimization, and observability of mobile backends on GCP.
• Ensure that security best practices are followed in the configuration of GCP infrastructure and deployment pipelines for mobile backends.
• Create and maintain detailed technical documentation on deployment architecture, processes, and troubleshooting guides specific to our mobile backend infrastructure on GCP.
• Proactively identify and implement improvements to our GCP infrastructure and DevOps processes to enhance efficiency and reliability.

Required Skills

• Strong proficiency with Google Cloud Platform (GCP) services, including services like Cloud Run, BigQuery, Cloud Storage or Networking
• Solid experience with Infrastructure as Code tools (e.g., Terraform) for provisioning and managing GCP resources
• Solid Experience with containerization technologies (e.g., Docker)
• Solid Experience with monitoring and logging tools specific to GCP (e.g., Cloud Monitoring, Cloud Logging, Prometheus, Grafana)
• Experience with some programming languages (preferably Typescript, JS, Go or Python)
• Knowledge of version control systems (e.g., Git)
• A strong preference for working in agile and dynamic environments
• Expertise in fostering teamwork, enabling effective collaboration and synergy across teams for continuous improvement
