Most Loved Workplace® Certified JobAbout the Role
At Titans freelancers, a Most Loved Workplace® certified employer in the Information Technology space, Leading IT outsourcing partner connecting skilled freelancers with ambitious companies.
Titan builds AI software for banks: purpose-built small language models, a banking ontology, and AI bankers that financial institutions can trust. Our models outperform general-purpose LLMs by 30 to 80 percent on banking tasks. We operate under the compliance, audit, and model-risk standards that banking requires. Titan is growing from a handful of live banking customers to thirty, then to hundreds. This role sits across the AI Toolbelt and Product Engineering lanes, owning the production AI systems that bank employees use every day — agent workflows, retrieval pipelines, and LLM integration layers. We bring a problem and expect a working solution.
