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\n This role focuses on designing and building agentic systems that power creative workflows for short-form video. You'll help shape how AI agents reduce friction, accelerate learning, and unlock new creative possibilities for our users - building agents that can take creative actions on a user's behalf - while experimenting with emerging models and techniques to bring these experiences to life in production.\nSoftware Engineers on the agents team work across product, machine-learning, and systems engineering - owning meaningful problems end-to-end and helping define how our agents are built and deployed across the product.\nWhile we don’t use hierarchical titles or levels internally, we are currently hiring engineers who have operated at senior or staff+ scope.\nResponsibilities\nBuild and ship end-to-end agentic systems that meaningfully improve creative workflows, balancing quality, performance, and reliability\n\nDesign agent architectures - how agents gather context, plan, select tools, and execute creative tasks reliably at scale\n\nIntegrate state-of-the-art models, combining internal research and external capabilities to power new agent experiences\n\nMeasure and improve agent quality in production, using experimentation, evaluation frameworks, and real-world feedback to guide iteration\n\nWhat Makes You a Great Fit\n5+ years of professional industry experience\n\nA track record of designing and developing ML systems or agentic pipelines in production\n\nDeep experience with context engineering: RAG systems, token optimization, context management at scale\n\nExperience building evaluation systems and agentic infrastructure (context gathering, tool selection, multi-step planning)\n\nExceptional problem solving fundamentals and ability to learn quickly in a rapidly evolving space\n\nAble to operate effectively in an extremely fast-paced environment and scope and deliver projects end-to-end\n\nEven better if...\nYou have worked with multi-agent architectures\n\nYou have experience fine-tuning LLMs for specific use cases\n\nYou have a pulse on where generative media and agentic AI 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 and prohibits discrimination and harassment of any type without regard to race, color, religion, age, sex, national origin, disability status, genetics, protected veteran status, sexual orientation, gender identity or expression, or any other characteristic protected by federal, state or local
