Job Analysis:

The role of Application Engineer at Discover is fundamentally about building high-quality, secure, and reliable software solutions that directly impact millions of users’ financial experiences. This position goes beyond basic coding; it requires an engineer who understands the full software development lifecycle—from analyzing requirements and designing features to implementing, testing, and deploying them efficiently. The emphasis on multiple programming languages like Python, Java, Scala, and C along with microservices and API development suggests that the candidate will work on diverse, scalable backend systems. Experience with cloud platforms (AWS, GCP, Azure) and big data streaming/real-time data engineering is critical because the job relies on modern, distributed architectures that must handle large volumes of transactional and sensitive data. The inclusion of ETL/ELT and database programming aiming at varied DBMS platforms points to a need for strong data handling and integration expertise. Candidates are expected to exercise critical thinking to balance new feature innovation with operational stability and security, vital in a regulated financial environment. The role will likely involve cross-team collaboration, including coordination with product owners and operations, where clear communication and the ability to navigate ambiguity are essential. Success in this job means delivering robust, scalable features rapidly yet safely while continuously improving code quality and operational resilience. The 10% domestic travel indicates occasional on-site collaboration or stakeholder engagement. Overall, the role suits a technically versatile, problem-solving engineer who thrives in a collaborative, compliance-oriented environment.
