About this role

Flux is seeking a Software Engineer for Agentic Products to join its San Francisco office on a full-time basis. This role suits an experienced engineer with a background in generative AI and full-stack web development who wants to help build the world's first AI hardware engineer.

Role Overview

Flux is building software capable of designing real, manufacturable electronics straight from a natural language prompt. As a Software Engineer specializing in agentic development, the mission is to build the reasoning graphs, agentic workflows, and integrations that enable both novice users and seasoned electrical engineers to create hardware seamlessly. This position blends advanced web engineering with artificial intelligence systems design by embedding intelligence directly into the design environment.

Key Responsibilities

Build agentic reasoning capabilities using TypeScript and LangGraph.
Incorporate artificial intelligence behaviors into the Chat UI and the React and Redux-based Flux web app.
Setup telemetry and logging to track runtime health, system performance, and cost.
Partner with electrical and product engineers to design intelligent electronic computer-aided design workflows.
Design and analyze evaluations and convert data findings into engineering choices.
Establish agentic design patterns and standards for the engineering team.

Requirements

Minimum of 5 years of professional software engineering background, including at least 1 year building generative artificial intelligence or agentic systems.
Proficiency in TypeScript, React, and Node.js.
Background using LangGraph, LangChain, or similar orchestration tools.
Proven track record of launching asynchronous, distributed systems into production environments.
Practical knowledge of embedding language model systems into complex web products used by customers.
Strong communication skills suited for an asynchronous team environment.
Background working in startup settings or zero-to-one product creation.

Nice to Have

Familiarity with retrieval setups, evaluation pipelines, or agent benchmarking.
Past contributions to open-source developer tools or artificial intelligence projects.
Knowledge of electronic computer-aided design or hardware design ideas.
Experience in applied machine learning, natural language processing, or data-driven experimentation.
Background building distributed, highly available systems operating at scale.
