Job Description

Our client is building the worlds first operating system for data and AI. Like iOS, Windows and Linux, our clients' end-to-end OS offers ever-evolving, automatically operated, best-of-breed open-source components tailored to each of their clients unique data security needs.

Our client serves large enterprises—often in air‑gapped data centers and complex deployment environments where failure isn't an option. It's one of the biggest value props of the product and presents unique technical and product challenges. If you thrive in ambiguity and enjoy making the unknown known while solving problems that matter, you'll fit well within the company and team.

The role

We are looking for passionate engineers who have extensive experience operating Kubernetes, building Kubernetes controllers, and control flow design and implementation. You'll lead and own complex platform features and enterprise customer implementations end‑to‑end—from architecture and development to deployment strategy and customer success. Your technical decisions directly impact how enterprise-scale organizations operate.
You'll work side-by-side with customer stakeholders from technical teams to C-suite executives, transforming complex business challenges into production-grade AI solutions while establishing best practices that define the industry. As a startup, you'll have significant influence on technical direction and team culture.

The ideal candidate

We're an engineering‑first organization focused on solving the hardest problems in enterprise data and AI. We eat, breathe, and sleep the latest in systems engineering and customer delivery, adopting new tech when it's battle‑tested (half a step behind the bleeding edge). If you're excited about technical leadership that creates real-world impact and working on technology that transforms industries, you'll fit right in. We value high productivity, customer obsession, technical excellence, self-sufficiency, and autonomy without the ego.

What's the stack?

Multi-tenant platform components run on Kubernetes with React/TypeScript frontends and TypeScript backends. Enterprise deployments leverage our advanced DevOps automation built on Kubernetes, Helm, and Terraform, with sophisticated implementations for enterprise security, compliance, and air-gapped environments where security and reliability are paramount.
We believe in picking the right tool for the job. If another AI framework or technology is better for creating breakthrough customer solutions, we'll use it.

Examples of what our client builds- Enterprise-scale GraphRAG systems that transform how Fortune 500 companies leverage institutional knowledge- Sophisticated multi-agent workflows that automate complex business operations previously requiring human expertise- Production AI platforms that integrate multiple cutting-edge frameworks to solve industry-defining challenges

You'll lead these breakthrough initiatives from vision to transformational reality, working directly with executive stakeholders to create lasting competitive advantages.

Skills we're looking for

• Enterprise platform experience with complex, mission-critical deployments where failure has real consequences
• Self-sufficient technical leader. You have taste for scalable architectures that solve problems others can't
• Ability to independently architect platform solutions that become the backbone of enterprise operations
• Comfort with ambiguity; turn complex, high-stakes customer requirements into clear technical solutions with minimal guidance
• Strong analytical mindset and proven ability to solve complex technical problems under pressure
• Leadership experience mentoring engineers and driving technical initiatives that matter
