About Cirql One

We believe the real value of modern enterprises lies in their data.

Most large organizations already have the data they need. What they lack is a way to work with it at scale. Over time, meaning gets buried in legacy systems, configurations, customization, and undocumented logic. The data still runs the business, but it can’t easily be trusted, reused, or reasoned over consistently by modern software and AI.

SAP sits at the center of this problem. It runs the core business process of more than 90% of Fortune 500 companies. SAP has spent decades perfecting systems of record while AI is building systems of reasoning, and the real opportunity lies in connecting the two. SAP systems are deeply embedded, business‑critical, and designed to change slowly. They are complex systems, refined over decades to ensure precision and control. Yet while the data is reliable by design, its business meaning is often implicit and difficult for AI systems to interpret, which prevents AI from reasoning over it reliably, safely, and at scale.

At Cirql One, we’ve spent more than 30 years working inside these environments. We know why AI systems struggle to interpret enterprise data correctly, that many existing semantic layers stop at technical abstraction, and why business meaning must be made explicit to scale trust, reuse, and automation.

What We Do

Cirql One is a startup focused on building the missing link between ERP systems and AI: an SAP-native semantic intelligence layer that gives AI models and agents a shared, business-accurate understanding of enterprise data. Our vision is to be the new system-of-reason sitting above SAP - where intelligence, metrics, and AI automation are defined, governed, and executed.

The result is a stable foundation for AI, automation, and analytics that can evolve independently of the underlying systems.

Tasks

We are building a platform that manages immense complexity—ontologies, data pipelines, and AI reasoning. Our frontend is not a thin layer, it’s where complex data, semantics, and AI behavior become tangible for users.

We are looking for a Senior Frontend Developer to take ownership of building robust, maintainable UIs for a complex platform, working closely with UX, backend, and platform teams.

This is a hands-on role in an early-stage product, with real architectural influence from day one.

What You’ll Work On

• Building and maintaining high-quality frontend applications for complex workflows
• Defining frontend architecture, state management, and performance patterns
• Integrating cleanly with APIs and backend services
• Collaborating closely with UX to translate designs into durable implementations
• Helping establish frontend standards that support long-term product evolution

Requirements

• 7+ years of frontend development experience in modern UI technology stacks such as React, Angular, etc.
• Strong skills in modern frontend frameworks, state management, and API-driven architectures
• Experience working on complex, long-lived applications
• Strong sense of code quality and maintainability
• Comfort operating in a fast-moving, ambiguous startup environment

Benefits

• Early-stage impact: Opportunity to build a groundbreaking enterprise AI platform using a modern web stack
• Hard problems worth solving: SAP semantics, AI-ready data, and enterprise-scale deployment — this is genuinely challenging and exciting work
• Strong team: Work alongside experienced founders and engineers who've built data platforms before
• Growth trajectory: As the platform and company scale, so does the scope of this role

If you’re interested in building frontend architecture that lasts, this role may be a fit.

Our process is straightforward and focused on real-world problem solving.
