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.
You’ll work across our backend infrastructure, data systems, APIs, and AI-powered workflows. This is a high-ownership role for someone who enjoys solving ambiguous technical problems, designing systems from the ground up, and shipping reliable production software quickly.
As an early engineer, you’ll have significant influence over our architecture, engineering practices, and product direction. You’ll work closely with our founders, product engineers, and applied AI team to turn complex product requirements into scalable and reliable systems.
You’re a great fit if you have:
3+ years of experience building and operating backend systems in production
Comfort working in a fast-moving environment with evolving requirements and limited structure

A builder mindset-you move quickly, care deeply about quality, and are energized 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
What You’ll Do:
Design, build, and operate reliable backend services, 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
