Senior Python Engineer (Data Science Products) - Smart City

Hey! Nice to see you!

 Let’s share our stories to get to know a bit better…. We are business and technology enthusiasts constantly hungry for new challenges, self-development, and development, and nothing motivates us more than great software products and happy customers.

At Incubly, we believe that great people want to work with great people, so we started building a company that would attract great minds and allow us to achieve everything without feeling like we're just working, but rather having fun. Our mission is to primarily support tech companies and startups (scaleups) in fast, high-quality scaling of their teams and in boosting their product development, testing, and deployment, so that we can succeed together.

 We’re currently partnering with Arrive, a leading global mobility platform powering smarter urban travel across more than 90 countries and 20,000 cities worldwide. Through well-known brands such as EasyPark, Flowbird, RingGo, ParkMobile, and Parkopedia, Arrive is transforming how people move by enabling seamless parking, smart payments, and electric vehicle charging. Their mission goes beyond mobility—it's about shaping more livable cities and creating better everyday travel experiences.

As part of this journey, we are looking for a Senior Python Engineer to join Arrive’s Data Science Products team on a 6-month contract (with possibility of extension). This team operates at scale, ingesting billions of complex sensor data points daily to power intelligent, real-time solutions that support millions of drivers globally.

 In this role, you’ll play a key part in developing and maintaining high-performance, data-intensive applications and infrastructure that underpin advanced machine learning products. You’ll work alongside a multidisciplinary team of engineers and data scientists to ensure systems are scalable, reliable, and built with long-term sustainability in mind.

Your daily responsibilities 

• Work independently on our Kafka services to integrate new sources and clients. We use Kafka to deliver near-real-time data to our machine learning models, other teams, and directly to customers. 

• Deploy and manage our cloud-native services using strong AWS knowledge and Infrastructure as Code principles. 

• Help operate and monitor the performance of our production services and platform. 

• Enhance our high-performance APIs, which utilise FastAPI to serve machine learning insights.

• Implement robust testing frameworks and system designs to maintain high code quality and service reliability. 

• Use AI throughout the software development lifecycle - we are continually evolving our working practices in this area, while ensuring systems remain reliable and maintainable. 

  We need you to have 

• Extensive professional experience in Python backend development, including building and maintaining highly available backend services (FastAPI preferred) at scale. 

• Proven ability to design, build, and maintain data-intensive applications and infrastructure. 

• Deep understanding of AWS services and hands-on experience with Infrastructure as Code (we use AWS CDK) and containerization (we use Docker and AWS ECS). 

• Experience with Kafka.

  Would be great if you have

• Experience working alongside data scientists in the "PyData" ecosystem (Numpy, Pandas).
