🚀 About us

We're a fast-growing Seed-stage startup building the next-generation search engine designed for AI and LLM applications. We are building a product which will operate on clusters of 1,000+ machines, processing petabytes of data and powering large-scale retrieval for production AI workloads.

🎯 The role

You will design and own the core infrastructure that everything else at Seltz depends on: Kubernetes, cloud environments, CI/CD systems, observability, internal tooling. The systems you'll build run across thousands of nodes, process petabytes of data, and need to stay up while the rest of the team ships fast.

This is foundational platform work. You will set the standard for reliability, automation, and developer experience across the entire engineering org. You will work directly with our CTO and founding engineers, with full ownership of your area.

📋 What you'll own

• Design, build, and maintain our core infrastructure, including Kubernetes, cloud environments, CI/CD systems, and internal tooling.
• Support and expand the scaffolding currently being built by our founding engineers, ensuring long-term reliability and maintainability.
• Build automation that enables the entire engineering team to move fast and safely.
• Implement best-in-class observability, monitoring, and alerting across all services.
• Collaborate closely with engineers working on crawling, indexing, vectorization, and search.
• Improve developer experience, build internal tooling, and help scale our production environment.
• Ensure world-class system reliability, performance, and scalability.

👤 Who you are

• You have strong experience with Kubernetes, cloud infrastructure (AWS, GCP, Azure), and CI/CD systems (e.g., GitHub Actions).
• You have designed, operated, or scaled large-scale infrastructure systems in production.
• You have a solid understanding of observability, reliability engineering, automation, and systems optimization.
• You are proficient in Python or another scripting language for internal tooling.
• You know or are willing to learn Rust
• You communicate clearly and work effectively across functions.
