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.

Compensation Range: $150K - $200K
