Our team tackles some of the hardest creative and technical challenges in generative media.\nWe get to rethink how people collaborate with AI that can actually do creative work with them-defining entirely new interaction paradigms for AI-native video tools. We make that possible by building multimodal agents that turn creative direction into edits, rendering engines that composite multiple layers of video and graphics, and generative video models trained from the ground up that create new media when needed.\nAll of this comes together in Captions, our creative workspace for generating, editing, and designing video. The technology behind Captions is now available more broadly: Tesseract gives any AI agent native video-editing capabilities, while developers can integrate our models into their own products through APIs.\nExplore our work\nCaptions - Our flagship creative workspace \nTesseract - Our professional video engine for AI agents \nResearch - The foundation models we build in-house \nUpdates - The latest from Mirage \nTechCrunch, Forbes, Fast Company - Press\nOur Investors\nWe’re very fortunate to have some the best investors and entrepreneurs backing us, including Index Ventures, Kleiner Perkins, Sequoia Capital, Andreessen Horowitz, General Catalyst, Uncommon Projects, Kevin Systrom, Mike Krieger, Lenny Rachitsky, Antoine Martin, Julie Zhuo, Ben Rubin, Jaren Glover, SVAngel, 20VC, Ludlow Ventures, Chapter One, and more.\nPlease note that most of our roles will require you to be in-person at our NYC HQ (located in Union Square) \nAbout the role\nBackend engineering at Mirage isn’t narrowly defined. We work across product, platform, and machine learning-building the systems, services, APIs, and ML pipelines that power all of our product surfaces.\nYou’ll own critical backend systems end-to-end, partnering closely with product, design, client, and AI teams to turn ambitious ideas into reliable, scalable production systems. This opportunity is ideal for engineers who enjoy solving complex technical problems while staying connected to product and user outcomes.\nWhile we don’t use hierarchical titles or levels internally, we are currently hiring engineers who have operated at senior or staff+ scope.\nResponsibilities\nDesign, build, and own backend systems end-to-end, including services, APIs, data pipelines, and infrastructure that power our products\n\nSolve complex technical challenges across distributed systems, scaling, concurrency, and performance\n\nIntegrate and operate large generative AI models in production-deploying, serving, and scaling systems that combine internal research and external capabilities to unlock new product experiences.\n\nInstrument, experiment, and iterate in production to continuously improve system and product quality\n\nDesign and operate core platform infrastructure, including integrations with third-party providers, storage systems, security, and internal APIs\n\nWhat Makes You a Great Fit\n5+ years of professional industry experience\n\nA track record of shipping high-impact systems and/or products in production\n\nExceptional problem solving fundamentals and ability to learn\n\nExcellent engineering taste combined with a strong sense of practicality and time-management\n\nAble to operate effectively in an extremely fast-paced environment as well as scope and deliver projects end-to-end\n\nEven better if...\nYou have worked extensively with LLMs, generative media models, and have a pulse on where the technology is going\n\nYou are grounded, collaborative, and willing to do whatever it takes to help the team win\n\nYou have been a startup founder or an early engineer at one\n\nBenefits:\nComprehensive medical, dental, and vision plans\n\n401K with employer match\n\nCommuter Benefits\n\nCatered lunch multiple days per week\n\nDinner stipend every night if you're working late and want a bite!\n\nGrubhub subscription\n\nHealth & Wellness Perks\n\nMultiple team offsites per year with team events every month\n\nGenerous PTO policy\n\nCaptions provides equal employment opportunities to all employees and applicants for employment
