Your impact Build the backbone of autonomous AI video creation — low-latency pipelines, real-time media processing, and ML orchestration at scale. As a founding engineer, you’ll help define our architecture, own critical systems, and tackle hard, high-leverage problems that sit at the intersection of GenAI, video, and ad performance. At Solid Labs, we’re building the first autonomous video creation platform powered by LLMs, real-time pipelines, and persistent brand memory — so marketers can scale video ads like never before. We're backed by top-tier investors and operators who’ve built category-defining AI and creative tech companies. As a Senior Software Engineer, Backend & ML at Solid Labs, you’ll join a high-impact team of AI researchers, frontend engineers, product designers, and creative technologists to build and scale the infrastructure powering our end-to-end AI systems. From serverless ML pipelines to scalable video processing backends, your work will enable powerful automation and insights for creative and marketing teams.
You will embrace open-ended problems around the development, deployment and scaling of ML models and have the opportunity to take ownership over a large scope of the design and development of our future product and pioneer new advancements in the way humans interact with creative GenAI features in the video and image space. You are the right fit if you’re passionate about creating user and business value and solving problems end-to-end with a strong product sense and design awareness. As a Senior SWE, you will partner with top global talent to build scalable, modular workflows and reliable AI models with user experience top of mind.

Why it matters
Video is the dominant language of the internet — but creating high-performing content is slow, manual, and fragmented. Creating self-learning video systems that generate, iterate, and improve content performance — autonomously
Hard problems, real use: From async orchestration and GPU optimization to data pipelines and video infra — this is applied AI at the edge
Ambitious, curious, global. We’ll reshape an industry and keep it fun while doing so! Team events, offsites and swag!
Top-of-market compensation: Salary and benefits package designed to attract top talent
Remote-friendly: with offices in Berlin, Cologne, and Vienna
Opportunity to work on cutting-edge problems in video, ML, and collaborative tools. Full time role: no contractors possible and we do not relocate.
