Senior Software Eng., Secure Client Engineering

About the role

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. 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%) Write code for native environments building component-based, performant, stable, and secure solutions with a focus on lower-level code that interfaces with the native operating system. 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. 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. 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. Experience with platform native (Windows or Mac OS) software development that interfaces with lower-level operating system APIs. Proficiency in reviewing and improving code structure and architecture for testability, maintainability, and scalability, with hands-on experience in multiple languages and frameworks such as C++, Swift, TypeScript, React, and Node.js. A love of learning and a growth mindset. Software engineering is your craft, not just your job. Strong problem-solving skills, working collaboratively with team members to develop solutions for non-trivial security challenges, and partnering with Product Owners to prioritize backlog. Strong technical research skills as it pertains to quickly building a working understanding of large open source repositories, as well as undocumented and closed source systems, to support solution design that extends beyond what may be publicly available for a given problem. Experience establishing software engineering standards and performing code and design reviews. Proven ability to pitch new ideas and implement improved systems and processes, delivering excelle
