Job description

Senior / Lead Mechanical Engineer | Product Development

Location: New Hampshire, USA

Working Arrangement: Hybrid - up to 4 days remote per week

Compensation: High pay rate, dependent on experience

Take the lead on innovative engineering projects

Are you an experienced Mechanical Engineer looking for a technically challenging role offering excellent pay and an attractive hybrid working arrangement?

An award-winning company based in New Hampshire is looking for a Senior, Lead or Principal Mechanical Engineer to support product development projects from initial concept through to manufacture.

This is an excellent opportunity for an engineer who enjoys taking ownership of the full development lifecycle, leading mechanical design decisions and turning complex engineering challenges into practical, manufacturable products.

You do not need previous medical device experience. The client is interested in engineers with a strong mechanical engineering background who have worked across a range of products and development projects. The key requirement is experience acting as the mechanical lead on a development, with a clear understanding of the engineering decisions behind the design and manufacture of a product.

Alongside the opportunity to take technical ownership of exciting projects, the role offers a high pay rate and a flexible hybrid working arrangement.

The opportunity

You'll take responsibility for mechanical engineering activities throughout the product development lifecycle, from early concept and CAD design through prototyping, testing and final manufacture.

The role is suited to an engineer who can work independently, make sound technical decisions and take ownership of a development rather than simply delivering individual design tasks.

You'll have the opportunity to work on a variety of products and engineering challenges, applying your experience to develop robust, practical and production-ready solutions.

Key responsibilities

• Lead mechanical design and development activities from concept through to manufacture.
• Take ownership of the full product development cycle, including design, prototyping, testing and design refinement.
• Act as the mechanical lead on development projects, understanding and explaining the rationale behind key engineering decisions.
• Produce and refine 3D CAD models and detailed engineering drawings, with SolidWorks preferred.
• Develop practical engineering solutions that balance performance, reliability, cost and manufacturability.
• Apply knowledge of materials, manufacturing processes, tolerances and design optimisation.
• Support hands-on prototyping, testing, troubleshooting and validation activities.
• Work collaboratively with wider engineering and manufacturing teams to deliver successful product outcomes.

What you’ll bring

• Strong experience in mechanical engineering, product design or product development.
• A proven track record of taking products from concept through to manufacture.
• Previous experience acting as the mechanical lead on a development project, with ownership of key technical decisions.
• Strong 3D CAD skills, ideally using SolidWorks.
• The ability to work across a range of products, technologies and development challenges.
• A practical, hands-on approach to engineering, including prototyping and testing.
• Strong problem-solving skills and the confidence to take ownership of projects from start to finish.

Previous medical device experience is not required. Experience in other industries involving mechanical design, complex products, mechanisms or product development will be considered.

High pay and flexible hybrid working

One of the standout features of this opportunity is the combination of a high pay rate and an attractive remote-working arrangement.

• Up to 4 days per week working remotely when CAD design work is being completed.
• Up to 3 days per week on-site when prototyping, testing and other hands-on development activities are taking place.
• Flexibility to work from home during design-focused stages while remaining involved in practical engineering work when required.
• The opportunity to work for an award-winning New Hampshire-based company on varied and technically challenging projects.

The working arrangement will depend on the stage of development, with remote work suited to focused CAD and design activities and on-site attendance required for practical testing and prototyping.

Why consider this opportunity?

• High pay rate: Excellent earning potential for an experienced mechanical engineer.
• Hybrid flexibility: Up to four remote-working days per week during CAD-focused stages.
• End-to-end ownership: Lead development projects from initial concept through to manufacture.
• Varied engineering challenges: Apply your skills across different products and technologies.
• Technical leadership: Take ownership of engineering decisions and influence the direction of product development.
• Award-winning company: Join an established organisation with an exciting pipeline of development work.
