We are seeking a Senior Software Engineer to join our Engineering team working on IAS’s core Signal 3 Platform—the foundation of our B2B offerings that powers products and partner integrations across the digital ecosystem. This team is revamping our core architecture, building modern, scalable API backend services, and driving our evolution toward cloud-native applications.

What you'll get to do:

• Design, build, and maintain Java-based applications and RESTful APIs that power IAS’s core Signal platform — including UI integration where needed to support new capabilities
• Scale applications and architectures to handle billions of transactions and records efficiently and reliably
• Lead the entire software lifecycle — from design and hands-on coding to testing, deployment, and observability
• Build and deploy cloud-native applications leveraging AWS (or equivalent cloud platforms like GCP/Azure)
• Collaborate closely with product and data teams to embed new capabilities and signal intelligence into our applications
• Work on backend systems and, optionally, data pipelines (Python experience a plus)
   

You should apply if you have most of this:

• 5+ years of hands-on Java development experience
• Strong experience with Spring Framework and Spring Boot
• Solid understanding of cloud platforms (preferably AWS) and how to design, deploy, and operate scalable cloud-based applications
• Knowledge of core AWS services (S3, DynamoDB, Lambda, EKS) or equivalent GCP/Azure components
• Strong grasp of designing for performance, scalability, reliability, and observability
• Exposure to frontend technologies (e.g., React) for UI integration or collaboration with UI engineering teams
• Experience building API backend services and integrating with distributed systems
• Excellent communication and collaboration skills
   

Bonus points:

• Experience with Python, especially for data pipelines or automation
• Familiarity with Databricks, Spark, or Delta tables
• Knowledge of SQL and database fundamentals
• Experience with messaging or streaming frameworks (Kinesis, Kafka, SQS, etc.)
• Understanding of Linux command line tools and DevOps concepts
