Senior / Staff Software Engineer, Product (Full Stack)

About Argon

At Argon, we’re on a mission to transform how life-changing therapies are brought to patients. We’re building the AI operating-system for the biopharma companies of the future where humans and AIs work alongside one another to handle complex research, writing, and coordination workflows.

We’re honored to enable the next generation of scientists and pharma companies to bring life saving therapies to market faster and more efficiently.

This role is right for you if you’re excited by the cutting edge product challenges that modern AI systems have surfaced. AI systems of the future will look and feel inherently different than previous software systems, and this role will shape AI agents and products in Life Sciences.

We value kindness, intensity, direct communication, intellectual honesty, and grit. Join us if you want to be productive, ship, and help build Argon AI.

We are an in-person company with offices in NYC. For non-NYC residents, we are happy to help cover moving and other related expenses.

Key Responsibilities

We are looking for a talented Senior / Staff Software Engineer, Product to join our team. In this role, you will build delightful AI products for the life sciences, including orchestration for distributed agentic systems to execute on multi step tasks and intuitive UIs for interacting with AI-native infrastructure.

1. Own systems end-to-end. Design, build, and operate distributed services that power our AI agents, retrieval, and workflow orchestration.
2. Work closely with the rest of the team to deeply understand workflows, develop user-journeys, and build an intuition around user problems and hypotheses for solving those needs.
3. Think deeply about the future of human and AI interaction and how AI will behave and feel in professional settings.
4. Build on top of the Argon platform using TypeScript, React component libraries, and a AI-native backend to bring designs and product vision to life.
5. Iterate quickly on frontend and create tight iteration loops by collecting signals on what is working and what isn’t across the product.
6. Conduct thorough code reviews, raise the quality bar, and establish taste/standards/best practices across testing, style, and documentation.
7. Mentor junior engineers, pair program, run design walkthroughs, and help others level up.

About you

1. Have 5+ years of professional software engineering experience, including leading projects from design to production.
2. Fullstack experience. You are familiar with our stack (React, TypeScript, NodeJS, PostgreSQL and Python)
3. Have designed and operated distributed systems with asynchronous workflows, concurrency, and eventual consistency.
4. Are fluent with Kubernetes and AWS primitives (SQS/SNS, S3, IAM, VPC).
5. Care deeply about code quality, maintainability, and developer ergonomics; you set standards and hold the line through code reviews and tooling.
6. Have product instincts and empathy for users; you balance shipping fast with building the right abstractions.
7. Have experience or is interested in working with AI native systems, orchestrating concurrent LLM streams, and prompt engineering.
