Job description

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

Qualifications / Additional Skills:

  • Experience building or integrating retrieval-augmented generation (RAG) systems

  • Experience working with enterprise security and compliance frameworks (i.e., SOC 2, GDPR, etc.)

  • Familiarity with embeddings, vector databases and large-scale document indexing

  • Knowledge of web automation tools and headless browser environments (i.e., Puppeteer, Playwright)

  • Understanding of sandboxed or containerized compute environments with strict access controls

  • Comfort designing user-facing agentic workflows and reasoning systems that span multiple modalities (text, vision, actions)

  • Experience using and fine-tuning models for screen reading, OCR, or UI understanding

  • Background in HCI or interest in building intuitive agent interfaces that extend human capabilities

  • Machine Learning experience as a double bonus

Why Work at Zyphra:

  • Our research methodology is grounded in methodical, step-by-step approaches to ambitious goals. Both deep research and engineering excellence are equally valued

  • We strongly value new and crazy ideas and are very willing to bet big on new ideas

  • We move as quickly as we can; we aim to minimize the bar to impact as low as possible

  • We all enjoy what we do and love discussing AI

Benefits and Perks:

  • Comprehensive medical, dental, vision, and FSA plans

  • Competitive compensation and 401(k) plan

  • Relocation and immigration support on a case-by-case basis

  • In-office snacks and meals provided

  • Unlimited PTO and company holidays

  • In-person team in San Francisco with a collaborative, high-energy environment
