If you want to work hard and create lasting positive impact, we want to hear from you. HOW WE WORK * High-velocity: Rapid experimentation, lean autonomous teams, and minimal bureaucracy. * Impact not job titles: We don’t have job titles. Instead, it’s about the impact you have. No task is above or beneath you. * AI first: We use AI to move faster with higher-quality results. We do this across the whole company—from engineering to growth to operations. * Excellence everywhere: Everything we do should match the quality of our AI models. * Global team: We prioritize your talent, not your location. WHAT WE OFFER * Innovative culture: You’ll be part of a generational opportunity to define the trajectory of AI, surrounded by a team pushing the boundaries of what’s possible. * Growth paths: Joining ElevenLabs means joining a dynamic team with countless opportunities to drive impact - beyond your immediate role and responsibilities. * Learning & development: ElevenLabs proactively supports professional development through an annual discretionary stipend. * Social travel: We also provide an annual discretionary stipend to meet up with colleagues each year, however you choose. * Annual company offsite: Each year, we bring the entire team together in a new location - past offsites have included Croatia and Italy. * Co-working: If you’re not located near one of our main hubs, we offer a monthly co-working stipend.

You will be responsible for shipping end-to-end features across the front and back ends of our stack, as well as helping set the direction of the features and products you're working on. * Collaborating closely with others on the Engineering, Growth and Sales teams to understand, and design solutions for, our customer and internal team’s most important problems and workflows. We believe in pairing engineers with work that matches their strengths and interests. This means that there is significant flexibility in staffing engineers across the company. Specific responsibilities might include:   * Improving our existing products to ensure that they’re intuitive, powerful and make innovative use of our research team’s latest break-throughs. This could involve making sweeping UX changes, adding significant functionality, or building integrations with other common consumer/enterprise solutions. * Designing & developing clean, intuitive, and functional user interfaces for products that will be used by millions of users and the world’s largest enterprises. * Working with internal teams and customers directly to synthesize feedback, understand user’s issues, and then design improvements and features to solve them. REQUIREMENTS We do not require any formal experience, certifications, or degrees. Instead, we are seeking enthusiastic software engineers who can showcase solving impressively hard problems with artifacts such as past projects, designs, or GitHub contributions. We do require: * Experience with Web Development using Typescript/React * Familiarity with common software and system design patterns and infrastructure including APIs, cloud infrastructure tools, storage solutions, data structures etc. * Interest in UI/UX design LOCATION This role is remote and can be executed globally.
