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.

Responsibilities & Duties

As a Senior Product Engineer, you will treat the product as your codebase. Your primary goal is to ensure technical feasibility meets user desirability from inception to deployment.

  • 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.

Qualifications & Skills

  • 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.

Benefits & Perks

  • Comprehensive Health Insurance (medical, vision, dental, life).

  • Employee Stock Option Plan.

  • Flexible PTO, Paid Holidays, and Paid Parental Leave.

  • Team events, happy hours, and an open, collaborative culture.

  • 401K.

What We Do

We are developing the next-generation manufacturing software platform for modern manufacturers. ION is a factory operating system that accelerates manufacturing and tracks parts and processes from prototype to full-scale production.

Why Work With Us

Unlike many tech companies, we are going after challenges in both the digital and physical worlds. Making software, processing data, and having sleek UIs is cool; but seeing your software start a motor for an electric aircraft is something else.
