The company

We spend more than 90% of our time indoors, an environment that can be up to 10x more polluted than outdoors. Today, air pollution represents the leading cause of environmental mortality in the world. According to the World Health Organization, more than 8 million people die each year because of unhealthy air quality, including 4,2 million due to bad indoor air quality. Sensilla helps companies increase the safety and wellbeing of their teams, by monitoring and improving air quality whilst offering energy reduction strategies.

We are seeking a dynamic individual who has proven experience as a full-stack software developer. You will play a key role in implementing the user interfaces for the Sensilla system. You will contribute to the system architecture, virtual infrastructure and software development environment. You will work closely with the product management team to build new components and interfaces that will extend the functionality of the Sensilla system.

If you love building software solutions and thrive in a dynamic environment, continuously improving the functionality of the Sensilla service, and at the same time developing your own skills, this is the position for you!

Review all existing source code (written in Python, TypeScript, JavaScript and Dart). Learn to build and deploy the complete system (firmware, back-end components, web applications, mobile applications).
  • Guarantee the high availability and scalability of the existing staging and production environments. You are also responsible for DevOps.
  • Assuming the role of full stack engineer in the software development team. The team lead will rely on your proposals to define the system architecture and count on you to implement the chosen solutions in a timely manner.

  • Produce user documentation for the customer-facing APIs and other integration points.
  • Produce technical documentation for the complete Sensilla system, to facilitate knowledge sharing within the team, and onboarding of new team members.

  • Develop and share best practices with team members to continually improve the quality, effectiveness, and efficiency of the software development processes.
  • Process feedback received from product management, sales team, and customer support teams about issues related to the service, software bugs, new features requested by the customers. Capture bug reports, proposed enhancements, and new feature requests in a product backlog management tool.
