Senior Product Engineer (Product Manager)

First Resonance•Los Angeles, CA

About The Position

Are you a Software Engineer turned Product Manager? First Resonance is looking for a Senior Product Engineer to become the bridge between software development, hardware manufacturing, and customer needs. This is not a role for a Jira administrator or a generalist manager. It is a role for a "builder" with deep engineering roots who is ready to take full ownership of designing, building, and delivering the digital ecosystem that powers modern factories. You will join a high-impact, small product team working directly with customers (building things like electric airplanes, robotics, and spacecraft) to turn messy, real-world manufacturing chaos into elegant, scalable software solutions.

Requirements

Mandatory Engineering Experience: At least 3+ years of professional experience writing production code (Full-stack, Backend, or Systems Engineering).
Manufacturing/Domain Expertise: Deep firsthand experience within manufacturing, hardware development, supply chain, or industrial IoT (e.g., you know the pain of inventory reconciliation or production planning).
Product Fluency: 2+ years of experience in product lifecycle ownership (as a PM, Tech Lead, or a founder).
Technical Stack Comfort: Mastery of web service architectures, API patterns (REST/GraphQL), and common data formats (JSON/XML).
Systems Thinker: Ability to understand a complex physical manufacturing process and immediately visualize the software system required to support it.

Responsibilities

Own the Technical Blueprint: Translate complex, raw manufacturing workflows into deep product specifications, user stories, and architectural requirements that our core engineering team can execute against immediately.
Rapid Prototyping & Logic Validation: You won't just draw mockups; you will "code in draft." Use your engineering background and AI tools to build functional prototypes, validate logic flows, and perform initial testing on complex integrations.
"In-the-Weeds" Discovery: Spend significant time with customer engineers and factory floor operators. Use your systems thinking to diagnose root issues and design solutions that traditional generalist PMs would miss.
API & Integration Strategy: Lead the definition and strategy for our external integrations (ERP, PLM, QMS) and internal APIs, ensuring a scalable and performance-oriented ecosystem.
Mentor and Bridge: Serve as the translator between business stakeholders and technical teams, elevating the product fluency of the engineering team.
