As a Founding Engineer, you will play a pivotal role in shaping the technical foundation of Voice Cursor. Your day-to-day responsibilities will include designing, developing, and scaling cutting-edge voice-first technologies, collaborating with cross-functional teams, and experimenting with new ideas to enhance human-computer interaction. You will lead the implementation of innovative AI-powered systems, optimize performance, and play a key role in defining the product roadmap.\n\nIn this Role you will:\n\nLead Context & Perception Engineering: Develop and refine VoiceCursor's real-time perception capabilities. You will build systems that securely read operating system states, accessibility trees, semantic structures, and visual surfaces, so our AI understands exactly what the user is looking at.\n\nOwn the Core Infrastructure: Design, build, and optimize the backend systems and low-level client logic that handles real-time audio streaming, LLM orchestration, and action execution.\n\nRapidly ship core updates based on real-world telemetry and performance data, treating latency and system reliability as your primary metrics for success.\n\nEngineer how we scale by continuously stripping away unnecessary architectural friction and building highly resilient, modular technical foundations, empowering the whole team to deploy at breakneck speed.\n\nPartner with the Product Engineering team to design flexible, API-first contracts, ensuring new AI capabilities and contextual features can be plugged into the user interface seamlessly.\n\nEstablish robust automated testing and benchmarking guardrails that allow us to leverage AI coding tools to safely accelerate our core development loops without risking regressions in performance or security.\n\nyou might thrive in this role if you:\n\nHave strong expertise in core systems engineering, with a deep understanding of how low-level technical decisions impact overall latency and reliability.\n\nHave experience with, or a strong desire to master, OS-level APIs (Accessibility APIs, window management, audio drivers) across macOS, Windows, iOS, or Android.\n\nPossess the hybrid mindset of a builder: You care deeply about making something people actually want, balancing hardcore technical optimization with pragmatic, product-driven execution.\n\nAre passionate about the future of Human-Computer Interaction (HCI) and are excited to tackle the incredibly complex technical challenge of giving AI real-time, zero-friction context.\n\nAre a former founder or have a history of attempting to build and launch your own products from scratch (this entrepreneurial DNA is a massive plus).\n\nCompensation:\n\nCash: $100,000 – $200,000\n\nInterview Process:\n\nHiring Manager Interview (50 min): A deep dive into your professional experience, problem-solving methodology, and team collaboration style.\n\nOnsite Interview(3-4 hours): includes a detailed product walkthrough, discussions on cross-functional collaboration, and a final session with the founding team.\n\n#J-18808-Ljbffr","company":"Voice Cursor","rawCompany":"voice cursor","city":"Millbrae","state":"CA","isRemote":false,"isActive":true,"createdAt":"2026-06-20T04:20:45.210Z","occupations":[{"code":"17-2199.00","title":"Engineers, All Other","slug":"engineers-all-other"},{"code":"15-1252.00","title":"Software Developers","slug":"software-developers"},{"code":"15-1299.08","title":"Computer Systems Engineers/Architects","slug":"computer-systems-engineers-architects"}],"industries":[{"code":"513210","title":"Software Publishers","slug":"software-publishers"},{"code":"541511","title":"Custom Computer Programming Services","slug":"custom-computer-programming-services"},{"code":"541512","title":"Computer Systems Design Services","slug":"computer-systems-design-services"}],"jobPosting":{"@context":"https://schema.org","@type":"JobPosting","title":"Founding engineer","description":"Voice Cursor is transforming how we interact with technology by introducing a voice-first alternative to traditional typing.
