Instead of agencies, long timelines, and infinite review cycles, teams give cardboard a footage + a goal (“3 variants”, “30s hook”, “testimonials”) to get a strong first cut in minutes on which they can iterate quickly. Multimodal LLMs can finally reason over footage, and WebGPU/WebCodecs make a real NLE possible in the browser. For the first time, an “AI director” inside a professional editor can be a reality. We have to build two hard things at once: a high-performance editor in the browser and an agentic editor that is reliable for production use cases. Most startups do one; incumbents can’t rebuild their stack without breaking everything. Saksham and Ishan met in school and have known each other since 15 years. Saksham was Co-founder/CTO of Iterate AI (backed by EF) and posts content on social media; Ishan has spent ~5yr building memory-heavy, performance-critical browser apps at HackerRank (S11) and deeply understands browsers. He has built Hotspoter (5M+ downloads) when he was 14. Together, we’re unusually suited to build the editor core others avoid. Video is becoming the default distribution channel, and the team that iterates fastest compounds attention. Cardboard becomes the default workspace for video production, the way Canva/Figma became the workspace for design - because it’s collaborative, fast, and does the tedious parts for you. ## About the role #### About - We're building the future of storytelling and video editing. - We're a small team that moves fast and builds things we're proud of. - We care obsessively about taste: in design, in product, in every detail. - We're solving [these](https://www.usecardboard.com/hard-problems) hard problems. - We're backed by a Tier-1 global fund, YC, and founders of billion dollar companies. #### Engineering Video is the most powerful way humans tell stories. It always has been. But creating it today is still painfully hard. Fragmented tools, steep learning curves, and workflows that get in the way of the actual creative work. We're building Cardboard to change that. Cardboard runs a real video editor in the browser, backed by a serious cloud media pipeline and an AI agent that actually understands footage. You will own how we measure and improve the quality of Cardboard’s AI agent. You will study real agent runs, turn important failures into evaluation cases, and measure whether changes make the product better. You will also work with product and engineering to ship those improvements. This is not a research-only, prompt-only, or QA role. You’ll be working alongside a team of engineers who all care deeply about craft, including the founders. You like owning problems end to end, and you’d rather ship something great this week than something perfect next quarter #### What you'll actually do - Define quality standards and build trusted evaluation datasets from real product usage. - Build offline and online evaluations, including automated checks and human review. - Analyze model and agent failure patterns, then improve quality through better data, evaluation methods, model selection, and, where useful, fine-tuning. - Add regression checks and release gates while tracking quality, latency, and cost. - Solve [these](https://www.usecardboard.com/hard-problems) hard problems. #### What we are looking for - Experience shipping and operating an LLM or agent system used by real customers. - Strong software engineering skills in TypeScript or Python, with the ability to work across both. - Experience building evaluations, datasets, experiments, or AI quality systems. - Strong product judgment and the ability to turn unclear quality problems into measurable improvements.You do not need a PhD or experience training foundation models. Evidence of building reliable AI products matters more than formal credentials or knowledge of a specific framework. #### Nice to have - Experience with multimodal AI, video, media, or creative software. - Experience with human labeling, model graders, or fine-tuning. - Good knowledge of experiment design and statistics. #### Within your first six months: - We have a trusted quality baseline for our main agent workflows. - Production failures regularly become new evaluation cases. - Important agent changes pass clear regression checks before release. - We can show measurable improvements in key editing workflows. #### What you get You'd be surrounded by people who are absurdly good at what they do. One started coding at 11 and shipped an app with 6M+ downloads in high school. One got into CS engineering at 14 and has been working on distributed systems for 8+ years. One's an ex-founder who took a company to 1.2M users and $300M+ in transactions. That's the team. We're looking for someone who'll raise the bar on technical craftsmanship and creative product quality. Apart from that you'd get: - Competitive salary and founding-team equity. - Unlimited tokens across every AI model. Use whatever you want, as much as you want. - A healthy budget for AI tools and any peripherals you need to do your best work. --- Source: Cardboard's own career page, read by RemJobs.
