👩🚀 Your impact
Build the intelligence behind autonomous video creation — multimodal pipelines, adaptive language models, and real-time learning loops. As a founding ML engineer, you’ll design the systems that power our AI avatars, generate compelling scripts, and learn from performance to get smarter over time. Your work will define the brains of our platform and unlock video creation at scale.
We’re building the first autonomous video creation platform powered by multi-modal LLMs, computer vision 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.
- 🏋️♀️ We’re already live with global DTC & eComm leaders in Europe
- 💰 Backed by one of Europe’s top early-stage funds
- 📈 Growing fast and hiring exceptional engineers to join early
Our goal is to build a small, but stellar team, and thus looking for a Founding Engineer. If you are excited to work in a very early-stage environment alongside technical & commercial serial entrepreneurs, using AI at the product core to solve meaningful problems – please reach out.
🧠 The Role
As a Senior Machine Learning Engineer, you’ll architect, build, and scale the AI systems that sit at the heart of our platform — from multimodal content generation to real-time inference and performance-aware learning.
You’ll own core components of our GenAI stack: embedding brand memory, creating adaptive scripts and scenes, and orchestrating model workflows across video, audio, and text. This role offers deep technical ownership — with direct product impact and fast feedback from top global brands already using the system.
🛠️ What you bring
- 5+ years of experience in ML engineering, applied research, or related roles
- Hands-on experience shipping production ML systems (esp. GenAI, multimodal, or creative tools)
- Strong command of Python and PyTorch (plus HuggingFace, Triton, or Ray frameworks)
- Experience building and scaling inference pipelines (serverless, GPU, latency-sensitive environments)
- Proven ability to design and iterate on datasets, training pipelines, and fine-tuning setups
- Strong product sense — you care about impact and user value, not just models
- Comfort working autonomously in fast-paced, high-ownership teams
👏 What You’ll Do
- Design multimodal systems: Build models and workflows that operate across text, audio, and video
- Ship LLM-powered tools: Use open-weight or custom LLMs to power use cases like scripting, tagging, captioning, and scene generation
- Embed brand memory: Develop persistent embeddings that capture brand voice, tone, and performance data
- Optimize for speed & scale: Architect inference pipelines with real-time constraints and cloud-native design
- Close the loop: Use ad performance data to drive iterative training and personalization
- Own full-stack ML: Lead across model design, training, evaluation, deployment, and monitoring
🫡 Why it matters
Video is the dominant language of the internet — but creating high-performing content is slow, manual, and fragmented. We’re changing that by:
- Rebuilding creation from first principles with LLMs, speech, and vision models connected through modular pipelines
- Giving marketers creative superpowers by collapsing dozens of tools into one intelligent system
- Creating self-learning video systems that generate, iterate, and improve content performance — autonomously
🎨 Why you should join us
- Now’s the time: Freshly funded, experienced founders, real traction, top customers — and early enough to still shape everything. You’ll have massive impact on the product, architecture, and our culture.
- Hard problems, real use: From async orchestration and GPU optimization to data pipelines and video infra — this is applied AI at the edge
- Full ownership: No middle layers, full access to customers, full-stack scope
- Team & vibe: Ambitious, curious, global. We’ll reshape an industry and keep it fun while doing so! Team events, offsites and swag!
📍 Location & Logistics
- Remote-friendly with Monday to Wednesday in office (Europe, HQ in Berlin)
- Start: As soon as possible
- Compensation: Top of market (incl. equity) (We’re constrained by bandwidth, not demand – great time to negotiate)
Interested? We’d love to chat about how you could help reshape the creative video industry together with us! Reach out to founders@withsolid.com
