Job description

Full Stack Software Engineer

Full-Time, Bay Area, Hybrid

Location: Bay Area / Hybrid

Type: Full-Time

Level: Senior

Why this role is exciting

Build complex AI-native product experiences end to end. Peer AI combines sophisticated document workflows, heterogeneous clinical data, collaborative editing, long-running distributed operations, and AI agents that perform work traditionally done by highly specialized domain experts. We want generalists who can take a problem from user need through architecture, implementation, testing, instrumentation, and production operation - and use AI to expand the ambition and quality of what a small team can build.

About Peer AI

We’re a Bay Area-founded, remote-friendly company backed by investors with deep roots in both technology and life sciences. Our platform is live with top-tier pharma customers today, and we’re growing fast in a $23B addressable market spanning document authoring, submission workflow management, and agency interactions with the FDA and EMA.

Our Vision

At Peer AI, we are working to clear the path for important scientific and medical discoveries, so that treatments reach the patients who need them as quickly as possible.

Our Values

• Drive Impact: We focus on delivering real results for our users. Making their work easier, better, and more impactful.

• Be the Expert: We lead with deep expertise, curiosity, and honesty to guide others toward the best outcomes.

• Go for Great: We take pride in pushing past “good enough” to deliver standout work in every detail.

• Win as a Team: We succeed together—building trust, sharing ownership, and helping each other grow every day.

How We Work

Peer AI is an AI-native company, and we want our engineering organization to be AI-native too. We use AI throughout how we build, test, analyze, debug, and operate software. We look for people who ask what can be automated, what should become a system instead of a recurring task, and where human judgment creates the most value. These roles are intentionally broader than their traditional equivalents because we want the people who join us to help redefine the function itself.

Key Responsibilities

• Own meaningful product capabilities end to end across our React/TypeScript frontend and Python/FastAPI backend.

• Work directly with Product, Design, and domain experts to turn ambiguous regulatory-workflow problems into simple, usable product experiences.

• Build APIs, data flows, and distributed workflows that support long-running AI and document-processing operations.

• Integrate LLMs and AI agents into reliable production workflows, with appropriate evaluation, fallbacks, and human control.

• Design for failure, recovery, observability, and data integrity rather than only the happy path.

• Instrument and test the features you build, and use AI coding agents and automation throughout development while maintaining a high bar for user success, correctness, maintainability, and engineering judgment.

Must-HaveQualifications

• Strong software engineering fundamentals and a track record of shipping production web applications.

• Ability to work comfortably across frontend and backend systems, including modern TypeScript/React and Python or similar server-side stacks.

• Experience reasoning about distributed systems, asynchronous execution, APIs, data models, and failure states.

• Strong product instincts and interest in understanding the user rather than only implementing a specification.

• High agency and strong debugging skills, plus experience using AI coding tools as a meaningful part of your workflow without outsourcing engineering judgment to them.

Nice-to-Have

• Experience building AI products, agentic workflows, evaluation systems, or document-generation products.

• Experience with AWS, FastAPI, React, PostgreSQL, asynchronous job systems, or collaborative editors.

• Experience with life sciences, regulated software, document systems, or other complex domain-heavy products.

WhatWeOffer

• Meaningful equity grant in a high-growth, venture-backed company.

• Remote-first setup with quarterly on-sites in San Francisco.

• Comprehensive health coverage, 12 weeks paid parental leave, and monthly home-office stipends.

• Unlimited PTO and a mission that directly accelerates life-saving clinical research.
