From MissionOne Media’s job post, as they wrote it.

We're looking for a Senior Software Engineer to join our engineering team building cross-channel management tools that turn massive, complex data streams into impactful actions across paid search, social, and retail media.

What You'll Do

* Core Engineering: Write robust, efficient, and scalable backend code primarily in Java.
* API Architecture: Design, develop, document, and consume robust REST APIs for seamless integration with internal microservices, frontend apps, and external partners.
* Database Optimization: Write and optimize complex SQL queries using major relational database management systems (e.g., MySQL) to ensure high data integrity and performance at scale.
* Collaboration & Workflow: Manage version control using Git and GitHub, focusing on clean code history, clear branching/merging practices, and collaborative code reviews.
* System Evolution: Contribute to modernizing our architecture, helping transition and scale services for peak performance.

What We're Looking For

* Java Expertise: 5+ years of professional software development experience, with dedicated, hands-on expertise developing and maintaining enterprise Java applications.

* Education: Bachelor’s degree in Computer Science, Software Engineering, or a related technical field.

Nice-to-Haves

* Hands-on experience deploying, managing, or monitoring applications on cloud platforms such as GCP.
* Hands-on experience with modern data stacks, particularly BigQuery and dbt.
