About the role

We’re looking for a Backend System Architect to help build the systems that power Coframe’s platform. This role is based in our San Francisco office, where our team works together five days per week.

Key responsibilities

• Design, build, and operate reliable backend services and APIs.
• Own technical projects from initial architecture through production deployment and ongoing operation.
• Build systems that process high volumes of events, experiments, and customer data.
• Improve the interoperability, reliability, performance, observability, and scalability of our platform.
• Make thoughtful architectural decisions while balancing speed, simplicity, and long‑term maintainability.
• Work closely with product and customer‑facing teams to translate real‑world needs into reusable platform capabilities.
• Help establish engineering standards and shape the technical foundation of the company.

• Comfort working in a fast‑moving environment with evolving requirements and limited structure.
• Strong software engineering fundamentals and experience designing distributed or data‑intensive systems.
• Proficiency in Python or another modern backend language.
• Experience building APIs, services, databases, and asynchronous workflows.
• A track record of owning meaningful technical projects from conception through production.
• Strong judgment around system design, reliability, and technical trade‑offs.
• Clear communication and a collaborative approach to solving problems.
• A builder mindset—moving quickly, caring deeply about quality, and energised by creating something from the ground up.
• Experience at an early‑stage or high‑growth startup.
• Familiarity with technologies such as AWS, Kubernetes, Docker, Kafka, and Postgres.
• Familiarity with evaluation systems, observability, orchestration, or distributed task execution.
• Experience working on systems where correctness, latency, and reliability directly affect the customer experience.
