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.

We are hiring a Senior Software Engineer with API expertise!

The Senior Software Engineer will work as part of Unacast’s API team, assisting in the development of customer‑facing and internal APIs with an emphasis on fast querying of large datasets. The APIs maintained by this team are the core building blocks of our data offering. Successful candidates will demonstrate an ability to translate business problems into technology solutions and products while overseeing the full application life cycle.

As a member of the API team, you will work closely with both engineering and product development to deliver creative and effective solutions.

This position requires significant prior Java development experience, including the Java Spring Framework. Experience with database management and SQL querying are critical as well as AWS experience. The ideal candidate will be team and customer service oriented, innovative, open‑minded to different solutions, and driven to deliver solutions that meet or exceed requirements. You believe that simple approaches are better than complex.

• Collaborate with product development and other teams to translate business initiatives into concrete technical requirements.
• Create innovative solutions to support partners and customers by building applications that deliver required functionality while adhering to best practices in development and testing. This includes the development of unit, integration, and runtime tests.
• Work with the engineering team on the optimal design and maintenance of the large Snowflake data lake that powers the APIs. This includes database table design and efficient SQL querying to produce short API response times.
• Create quality internal and external documentation for your work. Internal documentation is critical during the development and maintenance of a project and comprehensive external documentation is essential for customer onboarding.
• Create data, metrics and visualizations, as needed, for complex algorithm verification and optimization.

• You are both a team player and a self‑starter. You are comfortable working independently with only basic guidance, as well as working well within the larger team.
• You have demonstrated experience translating business problems into technology solutions, and deploying the right tool for the job including Scala, Java, third party web services, scripting languages (e.g. Python, R) and third party tool sets.
• You are capable of taking a basic description of what is needed, analyzing it and asking the right questions to generate a detailed specification of the software requirements.
• You can demonstrate that you have developed multiple applications from requirements elaboration to delivery to production.
• You must have great organization skills and strong communication and documentation skills.
• 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.

• 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.…
