As a Backend Engineer, you will take real ownership of the systems that power a fast-growing LLM-native product. This is a hands-on role focused on building reliable, high-performance backend services while shaping the foundations of a small, senior engineering team.

What You Will Do

  • Design and build scalable backend services and APIs supporting LLM-driven workflows

  • Own features end-to-end, from idea and architecture through deployment and iteration

  • Work closely with product, design, and leadership teams to support real customer use cases

  • Build and maintain cloud-native infrastructure with strong reliability, observability, and performance standards

  • Continuously improve system scalability, maintainability, and operational excellence

Tech Stack

Go (primary), distributed systems, APIs, cloud infrastructure, observability tooling, SQL and data pipelines
Experience in Go is a plus but not required; strong fundamentals in a statically typed backend language such as Java, C#, Rust, or similar are essential

About You

  • 2-4 years of backend engineering experience building production systems for customer-facing products

  • Strong understanding of systems design, API design, reliability, performance, and observability

  • Comfortable owning technical decisions and shipping independently

  • Product-minded, with a bias for action and low-ego collaboration

  • Clear communicator who thrives in small, high-trust, high-autonomy teams

  • Bonus: experience building AI or LLM-powered products

Be part of a small, high-calibre engineering team shipping real-world LLM products used by paying customers. This role offers strong ownership, technical depth, and the chance to help define the backend foundations of a rapidly scaling AI platform.
