Hardware Quality Engineer

Our Mission:
ButterflyMX is on a mission to empower people to open and manage doors & gates from a smartphone. Our products are installed in more than 15,000+ multifamily, commercial, gated communities, and student-housing properties worldwide, including properties developed, owned, and managed by the most trusted names in real estate. Our features are designed for developers, owners, property managers, and tenants and our products lower operating costs and improve tenant satisfaction.

Our Solution:
Developers and owners no longer need to run building wiring or install in-unit hardware. Property managers can grant building access, revoke permissions, and review entry logs from an online dashboard. Residents can open doors from their smartphones, issue visitor access, and see who is trying to enter the building.

Our Culture & Values:
Fantastic people are the key to our success. As a distributed, primarily remote workforce, we’re looking for more intelligent, passionate, collaborative, ai-forward, and down-to-earth individuals to join our growing team. We’re driven by a shared commitment to excellence and innovation, grounded in our core values: We delight our customers, We take ownership, We are a community of collaborators, We speak up, We think big and do small, and We are tenacious.

As the Hardware Quality Engineer, you will be the driving force behind the quality, reliability, and durability of all our hardware products. This hybrid role blends Quality Management, Quality Engineering, and Quality Inspection, giving you end-to-end ownership of our Quality Management System (QMS), supplier quality, product testing, and failure analysis. You will work closely with hardware engineering, manufacturing partners, and customer feedback channels to proactively embed quality into our designs, processes, and supplier relationships. Your mission: deliver ultra-reliable, high-performance products through a data-driven, proactive quality strategy.

Responsibilities:

Quality System & Process Development

• Develop, implement, and optimize an effective Quality Management System (QMS) to ensure continuous improvement and compliance with industry best practices.
• Establish and maintain quality policies, standards, and procedures covering design, manufacturing, supplier management, and field reliability.
• Define and drive corrective and preventive action (CAPA) processes based on field and manufacturing data.
• Own the Failure Analysis (FA) process, investigating product defects, conducting root cause analysis (RCA), and implementing long-term solutions. 

Design for Quality & Reliability

• Work closely with hardware engineers to integrate quality and reliability principles into the design phase, ensuring DFM (Design for Manufacturability), DFT (Design for Testability), and DFA (Design for Assembly) best practices.
• Lead product reliability testing, including environmental stress testing, lifecycle analysis, and accelerated aging tests to predict and mitigate failure modes.
• Collaborate with firmware and electrical engineers to analyze failure patterns and optimize testing strategies for circuit board assemblies and electromechanical components.

Supplier Quality & Manufacturing Oversight

• Develop and maintain supplier quality requirements, ensuring contract manufacturers and component suppliers meet or exceed our quality expectations.
• Define and implement Incoming Quality Control (IQC), In-Process Quality Control (IPQC), and Final Quality Control (FQC) strategies at manufacturing sites.
• Perform supplier audits, evaluate process capabilities, and work with vendors to continuously improve manufacturing quality.
• Establish clear acceptance criteria, inspection procedures, and statistical quality control (SQC) methods for key components and assemblies. 

Inspection, Testing, and Field Quality Assurance

• Define and oversee inspection criteria, test plans, and acceptance levels for hardware components and finished products.
• Lead failure investigations for field returns, customer complaints, and internal test failures, ensuring proper documentation and resolution.
• Own first article inspection (FAI) and production part approval process (PPAP) for new product introductions (NPI).

Continuous Improvement & Data-Driven Decision Making

• Utilize Six Sigma, Lean Manufacturing, and statistical process control (SPC) methodologies to improve product and process quality.
• Implement key performance indicators (KPIs) such as yield rates, defect rates, first-pass success rates, and customer return metrics to drive continuous improvement.
• Champion a culture of quality by training internal teams and suppliers on best practices, lessons learned, and continuous improvement initiatives.

• Experience in quality engineering, quality management, or reliability engineering in hardware, electronics, or electromechanical product development.
• Strong understanding of QMS frameworks (ISO 9001, ISO 13485, or similar) and experience implementing process controls in a manufacturing environment.
• Deep experience with root cause analysis (RCA), failure mode and effects analysis (FMEA), corrective and preventive actions (CAPA), and statistical process control (SPC).
• Hands-on experience with manufacturing processes, materials, and electronics assembly techniques.
• Proficiency in supplier quality management, including audits, process validation, and defect tracking.
• Knowledge of environmental, mechanical, and electrical reliability testing (thermal cycling, vibration, HALT/HASS, etc.).
• Ability to interpret engineering drawings, schematics, and specifications, including GD&T and IPC-A-610/620 standards.
• Strong cross-functional collaboration skills with engineering, operations, and manufacturing partners.
• Insatiably curious, especially around anomalies and failures, symptoms and root causes
• Passion for continuous improvement, innovation in quality methodologies, and delivering highly reliable products.
• Proven experience with leveraging AI tools in both professional and personal settings. ButterflyMX is an AI-forward organization and the ability to optimize efficiency using AI is crucial in every role.

• Comprehensive Medical (ButterflyMX covers 90% of the cost), Dental, and Vision plans (ButterflyMX covers 100% of the cost) starting day 1
• 401(k) plan with a match
