Job summary

Artos, Inc. is hiring a senior software engineer to join our small, highly technical team building AI-powered document platforms for life sciences.

You’ll impact product direction and architecture from day one. You’ll own features end-to-end across React/TypeScript frontend and Python/Node.js backend, design scalable systems for document-heavy workflows, and collaborate with product, design, AI, and customers to turn complex problems into robust software.

Qualifications

• 5+ years of professional software engineering experience building and shipping production web applications.
• Strong experience building backend services and APIs using Python, Node.js, or similar technologies, with the ability to contribute across the stack using technologies such as React and TypeScript.
• Solid understanding of application architecture, API design, databases, testing, and the fundamentals required to build reliable production systems.
• Experience building complex, data-intensive product experiences and integrating frontend applications with backend services.
• Strong product judgment and the ability to simplify complicated technical or business workflows into intuitive software.
• Comfortable debugging unfamiliar systems, and making sound technical decisions without requiring perfect specifications.
• Strong communication and collaboration skills, with the ability to operate effectively in a fast-moving startup environment.
• BS/MS in Computer Science, Engineering, or a related field, or equivalent practical experience.
• Nice to Have: Experience with LLM or GenAI-powered applications, document processing, RAG or retrieval systems, Docker/cloud infrastructure, or regulated industries such as life sciences or healthcare.

Responsibilities

• Own and build product features end-to-end, from React and TypeScript interfaces through backend services, APIs, data models, and production deployment
• Design intuitive experiences for complex, document-heavy enterprise workflows while building the systems required to make them reliable, performant, and scalable
• Develop AI-native product experiences that allow users to generate, review, validate, and interact with AI-generated scientific and regulatory content
• Work closely with product, design, AI, and customer-facing teams to turn real customer problems into high-quality software
• Make pragmatic technical and architectural decisions, improve the platform as it scales, and take responsibility for your work from initial concept through production
• Move quickly in an environment where requirements evolve, problems aren't always clearly defined, and engineers are expected to help determine what should be built—not simply how to build it
