Senior Mechanical Engineer

Department: Research & Development

Location: EMEA-Israel

Description

Align Technology is a leader in intraoral scanning, developing advanced opto‑electromechanical systems used by clinicians worldwide. Our products combine consumer‑electronics‑level design with the quality, reliability, and regulatory rigor of medical devices. As a Senior Mechanical Engineer, you will help shape the mechanical technologies behind next‑generation scanning platforms.

In this role, you will own the mechanical architecture and design of a complete electromechanical module, working closely with cross‑functional partners to deliver robust, manufacturable, and high‑performance products. You will be a key technical contributor in R&D, leading mechanical decision‑making, resolving complex engineering challenges, and acting as an escalation point across the product lifecycle.

This is a hands‑on senior individual contributor role with significant technical influence, focused on innovation, problem solving, and engineering excellence.

Key Responsibilities

• Own mechanical architecture, design, and integration of complex electromechanical modules within R&D
• Drive mechanical design decisions, trade‑offs, and risk mitigation across thermal, structural, and packaging domains
• Manage, review, and technically guide work performed by external mechanical designers and contractors
• Develop mechanical solutions for consumer‑electronics‑like products, balancing performance, reliability, cost, and manufacturability
• Lead and participate in technical design reviews, providing clear recommendations and direction
• Own hands‑on prototyping activities, including first system assembly, bring‑up, debugging, and iteration
• Collaborate closely with EE, Quality, Manufacturing, Program/Product Management, and external suppliers
• Support supplier engagement, DFM discussions, and technical problem resolution
• Perform hands‑on engineering work, including CAD design, tolerance analysis, and lab‑based testing and failure analysis
• Act as a mechanical escalation point, stepping in to resolve complex issues when needed, including downstream support to NPI or engineering teams as required

• Plastics and injection‑molded part design (including DFM)
• Sheet metal and CNC‑machined components
• Electronics packaging (PCBAs, connectors, thermal interfaces)
• Strong communication skills with the ability to influence cross‑functional teams
• Fluent English (written and verbal)
• Solid experience working with external suppliers and manufacturing partners
• Provide technical leadership and design oversight for external mechanical designers and contractors
• Demonstrated ability to lead design reviews and drive technical decisions
• High proficiency with SolidWorks (or equivalent), GD&T, and tolerance stack‑ups
• Hands‑on lab experience, including testing, troubleshooting, and failure analysis
• Ability to prepare clear technical documentation and present design reviews and recommendations to broad, cross‑functional forums

• Experience in medical devices or regulated products
• Background in reliability or verification engineering
• Experience designing tooling or test fixtures in an R&D context
• Familiarity with FMEA and PLM/ECO workflows
