Founding Product Engineer
Clera · San Francisco · $200,000–$300,000 (stated in the posting)
About the Role
Join an early-stage consumer AI company as its founding product engineer, with ownership of an AI assistant and its end-to-end user experience. You will work across agent behavior, product interfaces, and evaluation systems to help make everyday tasks easier for users.
What You'll Do
Build the agent decision-making layer, including tool-calling loops, memory, context assembly, prompt design, and model routing.
Create evaluation infrastructure with conversation replay, turn-level assessments, and regression suites to guide release decisions.
Own product experiences across mobile and web, from onboarding and initial interactions to ongoing use, group conversations, approvals, and trusted networks.
Ship features end to end, using experimentation and feature flags to measure outcomes and improve the product.
Develop integrations with email, calendars, bookings, payments, and browser automation, including reliable tool-use and user-approval flows.
Review conversations, speak with users regularly, and use feedback and product data to prioritize improvements.
Set engineering standards and help grow the team while remaining hands-on.
What We're Looking For
At least 4 years of software engineering experience at an AI product company, AI lab, or consumer product company shipping products at scale.
Production experience building agents with tool use, memory, and long-running conversations, along with evaluation systems that inform shipping decisions.
Full-stack experience with TypeScript, React, Next.js, and Postgres.
Experience with third-party APIs, OAuth, payments, or agent tools such as function calling, MCP servers, and browser automation.
A record of owning features end to end and demonstrating measurable product impact.
Strong product judgment, consumer experience sensibility, and fluency with AI-assisted development, including verifying and owning shipped work.
Experience leading a growing engineering team while staying hands-on, and evidence of sustained contribution at an employer or deep technical expertise.
Post-training or fine-tuning experience is a plus.
