College Board - Senior Mobile Engineer Location: This is a remote role. Candidates who live near CB offices have the option of being fully remote or hybrid (Tuesday and Wednesday in office). All CB employees are required to occasionally travel to meet in person for business purposes. Role Type: This is a full-time position AboutTechnology at College Board: We are a mission-driven engineering team building and evolving the technology that powers and protects the future of learning. Our systems support highly trusted education programs used by millions of students each year,operatingatsignificantscale and public responsibility. Today, we are focused on designing and delivering a critical new initiative that extends our platform in meaningful ways:blending foundational system work with thoughtful experimentation as we adapt to emerging technologies and new learner needs. We combine modern, cloud-native engineering practices with years of platform modernization, security hardening, and large-scale digital delivery,operatingas an experiment factory that tests assumptions and iterates based on evidence rather than tradition. What makes this team distinct is the rare combination of meaningful public impact, platform-scale technical challenges, and the freedom to shape how mission-critical systems are built and evolved. About the Team The Deliver team is responsible for building and operating the core products that deliver high-stakes digital assessments to millions of students each year. Today, this includes supporting flagship programs such as the SAT and AP exams, while advancing the technology that enables secure, reliable, and scalable test delivery across a wide range of devices and environments. The team focuses on delivering high-integrity proctoring and assessment experiences, ensuring performance, security, and consistency for students and educators at scale. Our responsibilities span two primary domains: We own the end-to-end student testing experience, including: Bluebook - the student-facing desktop application used to take digital exams Mission Control - a large-scale, AWS-based backend that supports authentication, test delivery, telemetry, resilience, and security Test & Results Packaging - systems that ingest, digitize, secure, package, and deliver test content to students through the Bluebook client Together, these systems must operate with extreme reliability, security, and performance at national scale. We also build the tools educators rely on during live testing, a new product consisting of desktop and mobile experiences that allow proctors to: Monitor student progress in real time Detect and investigate anomalies Troubleshoot student issues on test day This work directly impacts test integrity, educator confidence, and student outcomes. About the Opportunity As a Senior Mobile Engineer, you will play a key role in building and delivering hybrid( both web and native) mobile applications for both iOS and Android that power secure, high-quality digital assessment experiences. You will develop scalable, performant, and reliable solutions, contributing to design, implementation, testing, and technical documentation, while collaborating closely with cross-functional teams. The College Board, a not-for-profit organization dedicated to expanding access to education, delivers digital assessments at scale. As part of this mission, we are building next-generation proctoring applications for high-stakes exams that operate reliably across a wide range of devices and operating systems. Working within the Information Technology division and in partnership with product, security, and operations teams, the Senior Mobile Engineer will develop solutions that ensure secure, consistent, and reliable test delivery. This role requires strong expertise in native mobile development (Swift for iOS and Kotlin/Android SDK), along with experience integrating with OS-level and device capabilities (e.g., permissions, networking, device c ntro
