College Board - Technology - Platform Security Location: This is a fully remote role. Candidates who live near CB offices have the option of being fully remote or hybrid (Tuesday and Wednesday in office) Type: This is a full-time position About the Team Secure Client Engineering is part of Product Security and takes on some of the toughest security challenges in Bluebook, College Board's digital assessment application. Our team designs and builds the protections that help keep Bluebook secure and resilient across macOS, iPad, Windows, and ChromeOS. We are a small, deeply collaborative group of poly-skilled engineers who solve hard problems together, write production code, and share ownership of both the work and the outcome. Through ensemble programming, also known as mob programming, we bring a hands-on, high-trust approach to engineering that values curiosity, craftsmanship, and continuous learning. About the Opportunity As a Senior Engineer on the Secure Client Engineering team, you will play a hands-on role in protecting the integrity of Bluebook, the application students rely on for digital assessments across Windows, macOS, iPad, and ChromeOS. You'll work close to the operating system, leveraging native platform capabilities to tackle complex, low-level challenges at the intersection of software engineering and security. This role is built for engineers who thrive on hard problems without clear answers, using creativity and deep technical curiosity to design resilient client-side protections in an ever-evolving landscape. You'll collaborate with a small, highly skilled team, dive into the inner workings of native applications and system behavior, and continuously learn as you build robust, production-grade solutions. If you're motivated by mission-driven work, technical depth, and the opportunity to make a meaningful impact, this is a chance to shape how secure software is built. In this role, you will: Design & Implementation (75%) Collaborate daily with other engineers on the team using mob programming to solve complex technical problems through software engineering. Maintain the highest engineering standards in collaboration across teams with product owners, architects, and stakeholders, in support of our systems and services. Use your deep understanding of the applications within the Digital Assessment Platform to design and implement novel solutions to security challenges in desktop and mobile applications, across Windows, MacOS, iOS, and ChromeOS. Write code for both native and web environments, building component-based, performant, stable, and secure solutions with a focus on lower-level code that interfaces with the native operating system. Understand new product requirements and decompose the implementation into specific functional changes for verification. Team Operations & Success (25%) Drive continuous improvement of the team's engineering practices, efficiency, speed, and quality. Participate in conversations and offer opinions on proposed architecture, testing strategies, developer experience, security, performance, and resilience. Conduct and participate in peer code and design reviews. Assist in the resolution of production issues. Adhere to development standards and security policies and procedures. Adopt AI-augmented and agentic software engineering practices for rapidly implementing, testing, and delivering high-quality code based within the team's collaborative engineering model. Continuously develop the skills required to work in a poly-skilled, and increasingly AI-native, software engineering environment. Experiment with new methods or tools in a post-agile environment to improve the processes of the team. About you, you have: 6+ years of production level software development experience managing the entire lifecycle of features, including design, development, documentation, and deployment. Demonstrated software engineering experience using a variety of languages. Experience with platform na ive soft
