Help shape the future
of engineering software.

Metafold is building a fundamentally better way to do tolerance analysis. We’re looking for a seasoned dimensional engineer to join a team with deep expertise in geometry, mathematics, and software—and bring practical tolerance analysis expertise to the development of exceptional engineering tools.

You’ll contribute directly to product development, work closely with customers, and represent Metafold in technical conversations throughout the sales cycle. This role suits someone who combines strong engineering judgment with the ability to present clearly, build relationships, and get people working toward a shared goal.

We’re looking for someone excited about where dimensional engineering is heading, eager to keep learning, and ready to help a team of curious people move the field forward.

About Metafold

Metafold is a Toronto-based startup founded by mathematicians, with years of deep technical development behind us. We’re building a new paradigm for tolerance analysis, using advanced geometry to help manufacturers design better products and understand how they will perform. You’ll join a team with a strong technical foundation, ambitious goals, and substantial room to grow—and help shape what comes next.

The role

You’ll bring dimensional engineering expertise to a collaborative product team, applying experience from real products and production environments to next-generation tolerance analysis software.

You will

• Contribute to product direction: bring a practitioner’s judgment to product priorities, workflows, and capabilities, working closely with our geometry and software teams.
• Lead technical work: perform and review tolerance and variation analyses, investigate dimensional issues, and recommend practical design or process improvements.
• Connect variation to performance: help develop workflows that connect tolerance analysis with CAD, finite element analysis (FEA), and other engineering simulation tools.
• Validate performance: develop representative engineering cases, assess modeling assumptions, and evaluate results against established methods and measurement data.
• Build customer relationships: understand engineering challenges, lead productive technical discussions, and translate customer feedback into actionable insights.
• Support the sales cycle: deliver compelling demonstrations and presentations, scope technical evaluations, and explain the engineering and business value of Metafold’s approach.
• Learn and grow with the team: share expertise, explore new methods, challenge assumptions constructively, and help colleagues deepen their understanding of dimensional engineering.

What you bring

• Substantial professional experience in dimensional engineering, geometry assurance, or mechanical engineering with significant responsibility for tolerancing and variation analysis.
• A record of independently resolving dimensional problems in product development and production. You can explain the decisions you made and the results they delivered.
• Strong applied knowledge of GD&T, datum strategies, tolerance allocation, and assembly variation.
• Experience with 1D and 3D tolerance analysis, including worst-case and statistical methods, and sound judgment about when to use them.
• Practical understanding of manufacturing processes, inspection data, and process capability.
• Proficiency with CAD software and experience working with mechanical parts and assemblies.
• Working knowledge of FEA and engineering simulation software, including model setup, assumptions, boundary conditions, and interpretation of results.
• Excellent presentation and interpersonal skills. You can lead a room, communicate complex ideas clearly, and build credibility with engineers, managers, and prospective customers.
• A collaborative approach: you listen carefully, share knowledge, welcome constructive challenge, and take responsibility for shared outcomes.
• Curiosity about the future of the field and a desire to grow your expertise while helping others grow theirs.
• This is a senior role requiring demonstrated field experience applying dimensional engineering methods to real products. Coursework and certifications should be supported by practical experience.

Preferred background

• A degree in mechanical engineering or a related discipline, or equivalent practical experience.
• Electronics or electromechanical product experience, particularly connectors, enclosures, precision assemblies, or electronics packaging.
• Familiarity with existing tolerance analysis software.
• Experience in technical consulting, customer-facing engineering, applications engineering, or technical sales support.
• Experience improving engineering tools or workflows, or collaborating with software development teams.

Location

This is a hybrid position, with a preference for candidates based in Toronto. We will also consider strong candidates elsewhere in Canada, with working arrangements discussed during the hiring process.

Hiring process

• Introductory interview: discuss your experience, interests, and what you’re looking for, and learn about Metafold and the role.
• Practical exercise: work through a tolerance analysis problem to demonstrate your approach and engineering judgment.
• Technical interview: present your exercise results and discuss your reasoning, assumptions, and conclusions with the team.
• CEO interview: discuss your ambitions, Metafold’s direction, and how you could grow with the company.
