Zyphra is an artificial intelligence company based in San Francisco, California.
The Role:
As a Full-Stack Software Engineer, you will be a core contributor to Zyphra’s Agentic Systems and Interaction projects. You will be at the forefront of building a next-generation desktop and browser-based agent (end-to-end) that can autonomously navigate the web, interact with filesystems, and complete complex user tasks. This role spans agentic orchestration, frontend interfaces, secure sandboxing environments, large-scale document search and retrieval, and language/vision model integration.
You’ll Work Across:
- Design and implementation of different agentic system designs capable of interacting with browsers, operating systems, enterprise filesystems, collaboration tools, etc.
- Building search and retrieval pipelines across large-scale structured and unstructured data
- Build the backend layer for RAG systems and other information context management systems required for agents to operate
- Integrating LLMs, vision models, reinforcement learning, and scaffolding frameworks for autonomous, multi-step decision-making
- What matters most is your drive to build production-grade software
- We value velocity and curiosity, especially in fast-moving and ambiguous environments
What We're Looking For / Requirements:
- Proficiency in Python and a deep understanding of building and debugging complex end-to-end applications
- Experience working with SaaS environment and production workloads, web interfaces, databases, search engines, and queuing systems
- Experience developing browser extensions or automation tools with fine-grained control over the browser (mouse, tabs, DOM)
- Understanding of LLMs, prompting techniques, and orchestration frameworks for multi-step reasoning
- Ability to work across the whole stack from web interfaces to control plane and data infrastructure like queuing systems, databases, and search indexes
- Experience designing or working with secure and virtualized execution environments
- Excellent communication and collaboration skills across product, research, and engineering teams
