We are a team of experts with decades of unmatched industry experience and we partner with organizations across the private and public sectors to unlock the potential of location data. Unacast drives smarter decision-making based on trustworthy, reliable, and privacy-friendly location intelligence that powers both commercial and societal benefits.

We take a customer-first approach and are building APIs to provide valuable analytics across very large datasets, enlightening our customers to the “needle in a haystack” of big data. Our aim is to be the go-to leaders in location data, and we are now looking for a Senior Software Engineer to join our effort.

• You must be able to demonstrate proficiency in leveraging Generative AI tools to accelerate code authorship, unit testing, and debugging, while maintaining strict adherence to security protocols and data privacy standards.
  

Experience:

• 5+ years’ experience in Java 8 and higher software development with the Java Spring Framework used for REST APIs.
• Demonstrate excellent SQL database skills ranging from database initial creation and design, table design, automated load and maintenance processes, and efficient querying. Snowflake SQL is strongly preferred.
• Proficiency working in Amazon Web Services (AWS) and utilizing its many services.For example AWS Elastic Container Service for application deployment or AWS X-Ray for debugging.
• Experience processing data efficiently in JSON and GeoJSON.
  
• Proficiency in programming languages such Scala, Python or other similar programming languages.
