Job description

Overview

causaLens delivers Digital Workers that enterprises can truly rely on. Soon, competing without Digital Workers will be impossible. Just as it became unthinkable to manufacture without machines. We’ve built the first factory and Operating System for creating, deploying, and governing Digital Workers. For too long, enterprises have been bogged down by repetitive work, an overload of tools, and costly consultancies.

It’s time to simplify.

It’s time for Digital Workers to take on the repetitive workflows, freeing humans to focus on what matters most. Trusted by leading companies like J&J, Cisco, IPG Group, and Syneos Health.

Backed by over $50M in funding from world-class investors, including Molten Ventures (formerly Draper Esprit), Dorilton Capital, and IQ Capital, plus visionary angel investors such as the CEO of Revolut.

We’re looking for AI Engineers who are passionate about helping world-leading enterprises put cutting-edge AI agents into production. You’ll work on impactful, high-visibility projects - designing, building, and delivering intelligent solutions that solve real business problems at scale.

What you’ll bring

• Expertise in the deployment of enterprise-grade AI solutions to cloud and on-premise customer environments with a focus on availability, observability and security.
• Proven track record with at least one of the major cloud providers and an understanding of DevOps best practices.
• Hands-on experience building production-grade solutions using LLMs, RAGs, MCPs, and agentic workflows.
• Client-facing experience with a forward deployed engineering mindset. You’ll work directly with both technical teams and business stakeholders to understand real-world challenges and deliver solutions that drive measurable impact.
• Strong solution architecture and delivery skills: ability to translate complex business problems into scalable, intelligent AI solutions.

What you’ll do

• Collaborate directly with top-tier enterprises to understand needs, design and deploy bespoke agentic workflows.
• Design and implement robust architectures that leverage the latest AI technologies.
• Lead the delivery of high-impact AI products from concept to deployment.
