About the role
- Cinder safeguards the interaction layer: the front end of products that users engage - and sometimes abuse.
- Cinder is backed by Accel and Y Combinator.
- We care deeply about being relentless, intentional, and empathetic.
Responsibilities
- Own the complete lifecycle of large language model implementation: from data preparation and fine-tuning through rigorous evaluation and production deployment.
- Develop automated evaluation frameworks that continuously assess model accuracy, identify edge cases, and quantify improvements across iterations.
- Design and implement low-latency, high-throughput, cloud-based AI/ML systems capable of handling thousands of requests per second
- Build the foundational infrastructure - model serving, monitoring, deployment pipelines, and automated testing frameworks - that enables rapid experimentation and iteration while maintaining production reliability.
- We support some of the most important and innovative companies in the world, including OpenAI, Midjourney, and ElevenLabs.
- We're building an enterprise-grade platform to make the internet safer and we need highly curious, hard-working self-starters.
- We're looking for an engineer first - someone who builds, ships, and maintains production systems rather than writing papers.
Requirements
- 5-7+ years of engineering experience with demonstrated hands-on knowledge of applying LLMs and agents in industry
- Demonstrated ability to take models from research/experimentation through production deployment at scale
- Hands-on experience with LLMs and contemporary AI engineering patterns: RAG architectures, embedding models, vector databases, prompt engineering, and fine-tuning strategies
Nice to have
- Strong technical background in AWS cloud architecture and automated infrastructure provisioning with Terraform
- Experience with agentic frameworks like langchain is a plus
Compensation
- We are committed to fostering a vibrant, collaborative culture with a wonderful office, frequent in-person time to connect and innovate, competitive salary, generous benefits, and a 401k match, ensuring you are supported as you tackle defining industry challenges.
Benefits
- You'll contribute to the strategic vision for machine learning and AI at Cinder, collaborating with data and software engineers to build world-class AI capabilities that directly impact our product and business outcomes.
- Experience at a high-growth startup building machine learning infrastructure from the ground up
- As a fast-growing startup building critical AI software for some of the world's largest, most highly used, and most visible companies - your impact will be immediate and substantial.
