Senior Manufacturing Engineer – Mechanical

Aplin has partnered with an established Canadian manufacturer serving the nuclear industry to recruit a Senior Manufacturing Engineer – Mechanical for its Niagara Falls, Ontario operation. This is an excellent opportunity for an experienced mechanical/manufacturing engineering professional who enjoys working close to production and translating complex engineering requirements into practical, executable manufacturing solutions. The successful candidate will play an integral role within the Fabrication Engineering team, converting customer and design requirements into production-ready fabrication packages while working closely with Production, Quality, Procurement and Engineering. The Senior Manufacturing Engineer – Mechanical will bridge the gap between engineering design and shop-floor execution. You will be responsible for developing and releasing fabrication drawings, material bills of materials, manufacturing sequences, ERP routings and production orders while supporting tooling, fixtures, equipment selection and manufacturing process improvements. This is a hands‑on engineering position suited to someone who understands how components are actually manufactured and can identify and resolve manufacturability challenges before they affect production.

Identify and resolve design ambiguities and manufacturability constraints early in the project lifecycle

Provide real-time engineering support to resolve fabrication and production challenges

Develop, review and release general arrangement and detailed fabrication drawing packages

Ensure fabrication packages are technically accurate, complete and ready for production

Develop and maintain accurate material Bills of Materials (BOMs), including material specifications and piece‑part processing requirements

Work closely with Procurement regarding material requirements, supplier capabilities and sourcing considerations

Participate in design and manufacturability reviews for new and existing products

Apply Design for Manufacturability, Design for Assembly and Design for Inspection principles

Recommend practical design alternatives that improve manufacturability, quality, cost, safety and production efficiency

Develop manufacturing routings, fabrication sequences and operation requirements in collaboration with Production

Create and maintain production orders, ERP BOMs and manufacturing routings

Develop QC inspection requirements and support appropriate in‑process inspection parameters

Design jigs, fixtures and tooling to improve safety, quality, efficiency and manufacturing repeatability

Evaluate fabrication methods and manufacturing capabilities based on cost, schedule, quality and safety requirements

Support equipment and tooling selection for manufacturing operations

Participate in plant equipment and machine design associated with capital and operational improvement projects

Perform tolerance stack‑up studies, fit‑up evaluations and assembly interference assessments

Support continuous improvement initiatives across engineering and manufacturing operations

Qualifications

Bachelor's degree or College Diploma in Mechanical Engineering or a related mechanical engineering discipline
