Job description

ABOUT SYMMETRY We’re solving one of the biggest challenges in modern AI workflows: fragmented context. Today, project knowledge is scattered across conversations, tools, and docs-forcing teams to spend more time steering AI than actually getting work done. Symmetry brings context, continuity, and observability to AI-powered work, enabling teams to ship faster, work smarter, and maximize productivity across their existing AI stack. We’re a fast-moving, early-stage team with a proven track record of building and scaling successful AI businesses. Freshly funded and growing, we’re looking for builders who want to help define the next frontier of human–AI collaboration. ROLE SUMMARY You’ll own the systems powering Symmetry’s platform and Intelligence Layer-designing APIs, architecting data systems, and operating production services that are fast, fault-tolerant, and secure. You’ll work closely with product, design, and research to turn complex ideas into scalable, elegant systems that make AI workflows seamless and trustworthy. WHAT YOU’LL DO - Design, Build, & Maintain APIs: Build reliable, versioned interfaces that power Symmetry’s product and external integrations. - Architect Data Systems: Design and optimize relational, vector, and graph-based data stores that represent interconnected project context. - Build Distributed Services: Develop and scale backend systems using modern Python frameworks and asynchronous processing patterns. - Integrate AI Workflows: Combine retrieval and generation pipelines to deliver context-rich, adaptive intelligence within the platform. - Ensure Reliability & Security: Design for fault tolerance, enforce access control, manage secrets securely, and maintain compliance with data protection standards. - Operate in Production: Deploy, monitor, and optimize services with meaningful metrics, alerts, and incident response practices. - Debug & Optimize: Trace issues end-to-end, fix root causes, and continuously improve system performance and resilience. - Collaborate Cross-Functionally: Partner with frontend, design, and research to deliver reliable, user-centered experiences. - Own the Outcome: Document systems, write tests, and iterate post-launch using real-world feedback.
