From the employer
The next wave of enterprise software won’t be dashboards or copilots. It will be Digital Workers, autonomous AI systems capable of executing complex workflows end-to-end. At causaLens, we are building the platform that enables enterprises to deploy these Digital Workers safely and at scale.
Our Digital Worker Factory allows organizations to design, deploy, and manage AI agents that automate decision-making, analytics, and operational workflows across the enterprise. These systems are already being used by global companies including Johnson & Johnson, Syneos Health and Cisco to transform how work gets done.
Backed by $50M+ in funding from Molten Ventures, Dorilton Capital, and IQ Capital, and supported by visionary investors including the CEO of Revolut, causaLens is scaling rapidly. Our team includes leading AI researchers, engineers, and scientists, almost 20% with PhDs.

The Role
We’re hiring an AI Engineer to build and deploy enterprise-grade AI systems and digital workers in production.

We’re looking for engineers who want to apply advanced AI to meaningful business problems. You’ll contribute to systems spanning LLMs, multi-agent coordination, retrieval and reasoning, and enterprise data integration; building software that automates workflows and takes action, rather than producing static outputs.

What you’ll bring:
Proven hands-on experience building production-grade solutions using LLMs, RAG pipelines, MCPs, and agentic workflows
A forward-deployed, client-first mindset, with experience working directly with both technical teams and business stakeholders
Strong delivery capabilities, with the ability to translate complex business problems into scalable AI systems
A track record of delivering measurable impact through applied AI
What you’ll do:
Partner with leading enterprises to understand their needs and design tailored agentic workflows
Implement robust, scalable systems leveraging the latest advancements in AI
Own the end-to-end delivery of high-impact AI products, from concept through to production deployment
