About Technology 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, operating at significant scale 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, operating as 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 teamis responsible forbuilding andoperatingthe core products that deliver high-stakes digital assessmentsto millions of students each year. Today, this includes supporting flagship programs such as theSATandAP 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 deliveringhigh-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 mustoperatewithextreme reliability, security, and performanceatnationalscale. Wealsobuild 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 directlyimpactstest integrity, educator confidence, and student outcomes.
About the Opportunity
As aSenior Mobile Engineer, you will play a key role in building and deliveringhybrid(bothweb and native)mobile applicationsfor bothiOS and Androidthat 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 atscale. As part of this mission, we are building next-generationproctoring applications for high-stakes examsthatoperatereliably across a wide range of devices and operating systems. Working within the Information Technology division and in partnership with product, security, and operations teams, theSenior Mobile Engineerwill develop solutions that ensure secure, consistent, and reliable test delivery.
This role requires strongexpertiseinnative mobile development (Swift for iOS and Kotlin/Android SDK), along with experience integrating withOS-level and device capabilities(e.g., permissions, networking, device controls). You will build applications that perform consistently across environments, includingChromeOS, macOS, and Windows ecosystemswhere applicable.
The ideal candidate has experience buildingcloud-connected mobileapplications andis comfortableworking withserverless and event-driven architectures. You will contribute to systems built onmodular, scalable architectures, integrating mobile clients with cloud services, and supporting delivery throughCI/CD, infrastructure-as-code, and modern DevOps practices.
In this role, youhave:
Design and Development (60%)
Design and deliver high-qualitynative mobile applications (iOS and Android)usingmodular, component-driven architectures
Translate product requirements intowell-structured, testable mobile components, driving features from concept to production
Build and evolve applications usingSwift (iOS) and/or Kotlin (Android), integrating withOS-level and device capabilities(e.g., permissions, networking, device features)
