## Job description

## Our Mission

ButterflyMX is on a mission to empower people to automate property access, operations, and security from a single platform. Our products are installed in more than 20,000+ 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.

## Role Overview

We are looking for a stellar Mechanical Engineer to design, develop and support the physical and mechanical aspects of our current and future hardware products. You will be working collaboratively as part of a high-performance hardware development team on-site at our Hardware Engineering lab in Southern California, providing knowledge, expertise and design engineering of mechanical, physical, and thermal solutions. This role will report to the SVP Hardware and be accountable for leading and owning all mechanical, physical, and thermal aspects of our products from requirements and concept development through design review, vendor engagement, release, validation, and production support.

## Responsibilities

- Own the mechanical design of ButterflyMX products from requirements through production, including enclosures, molded plastic and metal components, mounting systems, and supporting mechanical structures.
- Translate product requirements, customer needs, and industrial design intent into robust mechanical solutions that meet functional, aesthetic, reliability, durability, cost, and manufacturability requirements.
- Rapidly develop, prototype, test, and iterate mechanical concepts using 3D printing, CNC machining, soft tooling, and other fabrication methods to resolve electromechanical challenges quickly.
- Design products for real-world and extreme conditions, including temperature, impact, vibration, moisture, and other environmental stresses; use FEA, structural analysis, and physical testing as appropriate to validate designs.
- Lead mechanical design reviews before releasing designs or significant changes to manufacturers; clearly communicate design intent, rationale, tradeoffs, risks, and open issues and incorporate stakeholder feedback before release.
- Collaborate closely with product, industrial design, electrical, firmware, quality, supply chain, and manufacturing teams to resolve conflicting inputs and drive alignment on an integrated product design.
- Proactively identify and communicate design risks, technical uncertainties, and capability gaps; develop validation, mitigation, and contingency plans when material risks remain.
- Identify, qualify, and work directly with manufacturing partners to resolve DFM, DFA, DFS, tooling, tolerance, cosmetic, material, process, and quality issues with minimal avoidable rework or schedule delay.
- Maintain complete, current, and controlled mechanical design documentation, including master 3D CAD models, STEP files, 2D engineering drawings, critical and inspection dimensions, tolerances, specifications, renderings, technical illustrations, and supporting product documentation.
- Own mechanical design changes and configuration control, ensuring updates from internal teams and external partners are reviewed, reconciled with requirements, aligned with stakeholders, and incorporated into the authoritative design before release.
- Establish realistic commitments and deliver mechanical designs, drawings, files, reviews, and feedback on time; track commitments in company project-management systems and proactively communicate schedule risks, delays, and downstream impacts.
- Operate with urgency and responsiveness when mechanical work affects dependent engineering, prototyping, testing, vendor, or manufacturing activities, providing timely information and decisions needed to keep work moving.
- Participate actively and professionally in internal and external meetings and collaborative problem-solving sessions, bringing clear mechanical engineering perspectives, decisions, and subject-matter leadership.
- Drive innovation by evaluating new materials, coatings, manufacturing techniques, and design approaches that improve product performance, aesthetics, installation, serviceability, robustness, or cost.
- Challenge assumptions and simplify designs wherever practical, reducing mechanical complexity and cost without compromising product quality, reliability, or user experience.

## Requirements

- Mechanical Engineering Bachelor's degree or equivalent relevant experience
- Fluent in SolidWorks 3D modeling software including FEA (Finite Element Analysis)
- Significant practical experience with sheet metal, cast and machined metal and plastics manufacturing processes
- Solid understanding of mechanical engineering fundamentals, including forces and torques, mass and basic thermodynamics
- Insatiably curious
- Fanatical about product design and all aspects of the creation of physical products
- Thrives in a fast-paced, collaborative product development environment with strong accountability and ownership

## Compensation

The expected base salary range for this position is $175,000-$190,000. Actual compensation will depend on factors including budget, skills, experience, location, and internal equity. This position may also be eligible for bonuses, equity, or other forms of compensation, where applicable.

- 401(k) plan with a match
- 10 paid holidays, 20 vacation days, 5 sick days, 3 floating holidays
