This role works with Elm, JavaScript, TypeScript, HTML, CSS, and even SVG Our Engineering Team Brilliant's engineering team is small, elite, and AI‑enabled. We believe in moving fast, fixing faster, and optimizing for outcomes over outputs. Our team is full of former founders, early employees, and engineering leaders turned ICs whose collective drive, judgement, and standards generate a palpable sense of momentum every day. The norm on this team is doing the very best work of our careers, and we both support and challenge each other every day to do exactly that. Compensation & Benefits We use a systematic compensation framework: salary scales are set each year for each job vertical, managers level folks on their team, and those levels are mapped directly to our compensation scales. A location‑based adjustment is applied outside of SF and NYC (typically 5‑10%) — feel free to ask us about your location! Given the systematic approach, we always make First and Best offers — there is no negotiation (for new hires nor our existing teammates). This ensures people are paid based on their expected contribution, not their negotiation skills. We offer top‑notch health care plans, with 100% of the premiums covered for medical, dental, and vision for employees. We offer flexible PTO, with a norm of taking off about 6 weeks per year (including federal holidays). We also provide home office equipment, a professional development stipend, and free food at our offices. Our CCPA Privacy Notice can be found here . Plus stock options. #J-18808-Ljbffr
