Beacon Biosignals is transforming precision medicine for the brain, from clinical development to clinical care. For Life Sciences partners, we offer the leading at-home EEG platform for clinical development of novel therapeutics for neurological, psychiatric, and sleep disorders. Our Diagnostics business is building the most comprehensive at-home platform for precision diagnostics, combining EEG and cardiopulmonary signals to deliver reimbursable assessments for sleep and central nervous system disorders. Together, we're changing the way patients are diagnosed and treated for any disorder that affects brain physiology. As a Senior Front-end Engineer, you’ll help power Beacon's mission by building first-class web applications that * drive forward new EEG analysis with data analytics capabilities * manage clinical studies of novel therapeutics * enable physicians to diagnose patients through at-home sleep tests This isn’t just another web app — you’ll be crafting tools that help unlock insights into neurological, psychiatric, and sleep disorders, with the potential to improve lives at scale. Beacon's robust asynchronous work practices ensure a first-class remote work experience, but we also have in-person office hubs located in Boston and New York. WHAT SUCCESS LOOKS LIKE As part of our small, mission-driven Web Apps Team, you will: * Develop our React/Typescript web applications. * Design and implement UX workflows for clinical study management, data analytics, and patient diagnostics. * Own the user experience, performance, reliability, and observability of the web apps and features you develop, leveraging feedback from real users in a diverse set of use cases and environments. * Partner with product designers and cross-functional teams to develop user-centric capabilities that empower a wide set of user personas, both internally and externally. * Help shape the roadmap and technical direction of our web applications. In your first 3–6 months, you might: * Build a new feature for visualizing insights into an ongoing clinical trial. * Develop a physician workflow for turning outputs from our AI algorithms into a customized diagnostic report. * Enable study sites to better manage the enrollment of study participants. * Deploy new features to help our Clinical Operations team track compliance. WHAT YOU WILL BRING * 8+ years of experience in front-end web development (React and Typescript). * Experience developing data-rich applications involving interactive visualization and manipulation of large amounts of data. * A product mindset — you care deeply about UX, edge cases, and performance. * You're familiar with GraphQL-based APIs, and can build consumers that scale well. * You're adept at identifying optimization bottlenecks, and debuggers and code profiling tools are an important part of your toolkit. * Strong communication skills and comfort working in a collaborative, async environment. Bonus points if you've: * Worked on applications for clinical trials, patients, or in some other regulated environment. * Have experience in EEG or with DSP. * Have worked on back-end systems or infrastructure. * Contributed to open source React/Typescript projects.
