SENIOR MECHANICAL DESIGN ENGINEER

Downhole Oilfield Tools - Oil Well Intervention (Upstream)

Aberdeen | £70,000-£80,000 + Bonus + Private Medical | Relocation Considered for UK Citizens Only

Design oil well intervention tools that actually reach the field - and know you were responsible for every stage.

This is a rare opportunity to join a privately backed, investment-funded upstream technology business entering a significant growth phase.

The company has recently secured funding to expand its product portfolio, accelerate new tool development, and scale internationally within the oil well intervention and completion markets.

This is not a cost-cutting, contraction story.

This is controlled expansion backed by capital and clear strategy.

The leadership team is composed of experienced upstream engineers and proven operators who have built and scaled oilfield businesses before. The culture is engineering-led, commercially disciplined, and highly accountable.

The Business

A specialist upstream downhole technology company operating exclusively in oil well intervention and completion tooling.

Focused on high-integrity, pressure-critical downhole tools
Developing proprietary, IP-protected technology platforms
Agile engineering environment with short decision cycles
Clear roadmap for product expansion and global reach
Strong leadership track record in scaling oilfield businesses

This is a serious engineering business with long-term intent.

The Role

As Senior Mechanical Design Engineer, you will take ownership of complex upstream oil well intervention tools from feasibility through to deployment.

You will:

Lead concept development for intervention and completion tools
Analyse hydrostatic pressures, load paths, fatigue and failure mechanisms
Perform advanced stress and load calculations
Conduct tolerance stack-up studies and apply GD&T principles
Develop complex Solid Works assemblies and detailed manufacturing drawings
Design and oversee validation test equipment
Participate hands-on in workshop build and testing
Lead technical design reviews internally and with customers
Support field trials and first-off installations
Deliver projects through structured engineering stage gates

This is full lifecycle engineering with visible accountability.

Essential (Non-Negotiable)

Degree or HNC in Mechanical Engineering
Minimum 10 years upstream oilfield downhole tools experience
Direct oil well intervention tool design exposure
Strong hydrostatic and pressure containment design capability
Advanced stress and load calculation expertise
Tolerance stack-up analysis experience
Strong Solid Works proficiency
Experience taking tools from concept through manufacture and deployment

Applicants without upstream oil well intervention experience will not be considered.

Why Consider This Move?

Engineers in large service companies often design one component of a system.

Here, you will:

Own the whole tool
Engage directly with customers
See your work tested and deployed
Operate in a high-performance, low-bureaucracy environment
Contribute to an ambitious growth plan backed by investment

This is for engineers who prefer ownership over hierarchy and impact over structure.
