Senior Full Stack Engineer

Air pollution kills 7 million people each year and has been closely linked with exaccerbating everything from respiratory diseases, to dementia and infertility. Air pollution causes 12% of deaths globally and lost productivity equivalent to 4% of global GDP.

Airly has developed a proprietary air quality monitoring solutions so governments and businesses can diagnose air quality issues, identify actions to improve, and verify their progress.

We need to massively accelerate the deployment of hyper-local monitoring to protect public health, inform our actions and hold authorities to account.

Airly was founded by Wiktor (CEO), Aleksander and Misiek, three physics graduates and friends from Krakow University in Poland.

Our COO is Jonathan Gartside, one of the founding leadership team at Bulb.

Airly’s team is made up of 20+ people, with the majority in the functions of product and technology (developing our proprietary integrated hardware-software solution) and growth (covering direct sales, partner-led sales, and public policy).

As a Senior Full Stack Engineer at Airly, you will play a significant role in the development and maintenance of our software products.

You will be part of a cross-functional team consisting of front- and back-end developers, a senior designer, working in Scrum methodology with the product owner, and maintaining close contact with the rest of our small team and external stakeholders.
The current goal of our team is to develop, in an iterative mode and constant contact with clients, a completely new solution: a productivity-enhancing software tool for air quality consultants. Simultaneously, part of your duties will involve ensuring that our current product performs well and utilizes up-to-date technologies without increasing its technical debt. This includes the Airly Data Platform, used by around a thousand of our clients.
You’ll have the freedom to use the newest tools and technologies, have the autonomy to implement your own ideas and solutions, ensuring that what you develop can be shipped to the production environment the next day, eliminating idle time and the need to wait for assigned tasks. You will also actively participate in designing changing architecture for future scaling, minimizing running costs, and rethinking support needs by deploying appropriate tools.
The aim is to provide the ability to analyze large time series of data and a web map, showing live results of air pollution around the world in more than 10 thousand locations, attracting hundreds of thousands of monthly active users.
