Hardware, Mechanical Engineer

Mecka AI; Toronto; On-site; CAD 75,000 - 110,000; Full time

Job summary

Mecka AI is hiring a Mechanical Engineer to turn precision capture hardware into durable, manufacturable products. You will own designs from concept to production, balancing precision, weight, thermal performance, and cost while working with suppliers and cross-functional teams.

Role requires hands-on prototyping, sensitivity to manufacturability, and strong CAD skills. Previous experience with wearable or sensor-mounted systems is a plus. Opportunity to impact data capture hardware at scale.

Qualifications

• 3–4 years of experience in mechanical engineering.
• Proficiency in 3D CAD (SolidWorks or Onshape) and producing clear engineering drawings.
• Solid understanding of mechanics, materials, tolerances, fits, fasteners, and dimensional inspection.
• Hands-on experience building prototypes and testing physical assemblies.
• Knowledge of manufacturing processes (machining, molding, sheet metal, additive manufacturing).
• Ability to package electronics and sensors with assembly, thermal behavior, and maintenance in mind.
• Experience working with suppliers to resolve part quality, manufacturability, and cost issues.

Responsibilities

• Design mechanical systems that support accurate recording and can be assembled, maintained, and manufactured efficiently.
• Build and test prototypes to improve fit, weight distribution, stiffness, and ease of use.
• Analyze tolerances, loads, and sensor alignment, and validate key assumptions with physical measurements.
• Partner with electrical and sensor engineers on packaging, thermal paths, cable routing, and service access.
• Review parts with suppliers and refine designs using assembly results, reliability testing, and field feedback.

Job description

About Mecka AI

Mecka AI is building the data infrastructure layer for robotics and embodied AI.
We design and operate global systems for data capture, data labeling, and hardware-enabled workflows used by leading AI labs and robotics companies to train and validate humanoid and embodied AI systems.
We work closely with frontier robotics teams to bridge real-world data, simulation, learning-based systems, and deployed hardware.

About the Role

You will turn precision capture hardware into products people can use every day. As Mecka expands data collection beyond the laboratory, your designs will preserve sensor accuracy while making devices durable, comfortable, and practical to manufacture at scale.

You will own mechanical designs from concept and prototypes through validation and production. Bring strong mechanical fundamentals, hands-on testing, and manufacturing judgment to resolve the tradeoffs between precision, weight, thermal performance, and cost.

What You’ll Do

• Design mechanical systems that support accurate recording and can be assembled, maintained, and manufactured efficiently.

• Build and test prototypes to improve fit, weight distribution, stiffness, and ease of use.

• Analyze tolerances, loads, and sensor alignment, and validate key assumptions with physical measurements.

• Partner with electrical and sensor engineers on packaging, thermal paths, cable routing, and service access.

• Review parts with suppliers and refine designs using assembly results, reliability testing, and field feedback.

What You Bring

Must-have:

• 3–4 years of experience in mechanical engineering.

• Proficiency in 3D CAD (e.g., SolidWorks or Onshape) and the ability to produce clear engineering drawings.

• Solid understanding of mechanics, materials, tolerances, fits, fasteners, and dimensional inspection.

• Hands-on experience building prototypes and testing physical assemblies.

• Knowledge of manufacturing processes such as machining, molding, sheet metal, or additive manufacturing.

• Ability to package electronics and sensors with assembly, thermal behavior, and maintenance in mind.

• Experience working with suppliers to resolve part quality, manufacturability, and cost issues.

Nice-to-have:

• Experience with wearable products, robot end effectors, handheld mechanisms, or precision sensor mounts.

• Experience with flexible materials, thermal analysis, or fatigue and durability testing.

About You

• You are ambitious about what you build. You can point to results you personally delivered.

• You care deeply about your craft, pursue difficult questions, and learn quickly.

• You take initiative and own problems through to results. You work independently, make decisions, and bring others in when needed.

• You communicate honestly. You own mistakes, share credit, and help the people around you succeed.

We strive to create an inclusive work environment for all; we welcome applicants from all backgrounds and are committed to providing equal opportunities. Should you require any accommodations during the recruitment process, we will partner with you to meet your needs.

We may use AI-assisted tools to help evaluate applications against the requirements of this role. These tools support our recruiting team in identifying qualified candidates but do not replace human judgment or limit which applications may be reviewed or considered.
