Job description
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.
We are particularly focused on pharmaceutical and life sciences organizations, where AI is rapidly becoming the operating system for commercial analytics, forecasting, regulatory workflows, and medical intelligence.
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 a Lead AI Engineer to design and deliver enterprise-grade AI systems and digital workers in production. You’ll work closely with global organisations, embedding with clients to untangle complex workflows and translate them into reliable, scalable agentic systems—integrating models, data, and enterprise infrastructure into solutions that operate in real-world environments.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Job requirements
We’re looking for experienced lead engineers who can own end-to-end delivery of advanced AI systems. You’ll work across LLMs, multi-agent coordination, retrieval and reasoning, and enterprise data integration; driving the development of systems that automate workflows and execute real business tasks at scale.
Our stack typically includes Python, modern LLM frameworks, orchestration tools, and cloud platforms such as AWS, GCP, or Azure.
What you’ll bring
- Deep, hands-on experience building and deploying production-grade AI systems using LLMs, RAG pipelines, MCPs, and agentic workflows
- Proven track record of leading complex, client-facing engagements with a forward-deployed mindset, partnering with both technical and business stakeholders
- Strong system design and architecture expertise, with the ability to translate ambiguous business challenges into scalable, reliable AI solutions
- Experience guiding technical projects, setting technical direction, and driving delivery to measurable outcomes
- Solid understanding of evaluation, reliability, and performance considerations in production AI systems
What you’ll do
- Work directly with enterprise clients to understand complex operational and analytical workflows
- Translate ambiguous business challenges into clear technical strategies and system designs
- Design scalable AI architectures and agentic systems combining LLMs, multi-agent orchestration, and knowledge retrieval
- Break down initiatives into structured engineering plans and drive execution across teams
- Lead technical delivery end-to-end, from architecture through production deployment and iteration
- Guide engineers through implementation decisions and provide strong technical leadership throughout delivery
