Senior Software Engineer (Scala) | AI & Mobility | Scale a global platform impacting millions
The Opportunity
Numi has partnered with a pioneering AI scale-up that is building the 'Recognition Economy'—a future where real-world friction vanishes and computer vision powers seamless consumer experiences. They are bridging the digital and physical worlds, starting by transforming how millions of people park, travel, and pay.
As a Senior Software Engineer, you will join their core application development team to drive the next phase of global growth. This isn't about maintaining legacy code; you will be designing and building high-throughput distributed systems from the ground up to support massive international expansion.
This role exists because the platform is scaling rapidly across global airports and retail hubs. You will have a direct hand in shaping product direction, mentoring peers, and utilizing cutting-edge AI-assisted workflows to solve complex architectural challenges.
What You’ll Be Doing
You will be a key driver of the backend evolution, taking ownership of the services that power a high-volume pre-book parking and e-commerce engine. Working closely with cross-functional teams, you will turn complex integration challenges into elegant, highly available solutions.
