Why join Cinder Technologies?
Every AI product that talks to strangers needs guardrails against abuse, fraud, and manipulation. Cinder, a New York trust and safety platform, could become the policy layer that AI builders and online platforms rely on to screen prompts, outputs, and tool calls. Accel and Radical Ventures back its Series B, and the company has raised $55M over four rounds with 9 open roles, 4 in engineering.
JustBacked's take, based on Cinder Technologies's own site and its funding and hiring data.
Cinder builds safety infrastructure for some of the most important AI and internet platforms in the world, including Midjourney, ElevenLabs, Synthesia and Black Forest Labs. We’re backed by Accel, Y Combinator, and Radical Ventures.
We’re building a network of specialists who test AI models for the ways they can cause real harm. When a customer project calls for your expertise, we bring you in on a paid, project-based contract.
We want to hear from:
Red teamers and jailbreakers with hands-on experience getting frontier models to break
Testers with experience across image, video, and audio generation, or in agentic and MCP-connected systems
Experts in specific domains, including child safety, CBRNE, violent extremism, NCII, cybersecurity, fraud, self-harm, psychology, and copyright
Native speakers who can test models in languages and cultural contexts beyond English
Projects vary in size and timing. Once you’re in the network, we’ll reach out when a project matches your background.
