Description

The Role

We are looking for a creative and driven Senior Mechanical Engineer who will lead the design, development, prototyping, and delivery of electromechanical systems, automated production line systems and pressurised fluid delivery systems. The role is accountable for technical ownership of projects, mentoring junior engineers, and delivering production-ready solutions with urgency. It directly supports the Engineering department’s objectives:

Strengthening and supporting existing hardware for operations.
Designing the next generation of production line systems to increase throughput.
Creating novel solutions in food coating application, soft food moulding, and related technologies to ensure and retain market leadership.

As we are a small team, your role and activities will be wide-reaching. You will be joining OGT at an exciting period of growth and this is an excellent opportunity to make a real impact and share in our success.

Key Responsibilities

Lead the selection, design, prototyping, testing, and delivery of electromechanical systems and automated manufacturing equipment.

Produce and maintain CAD models, technical specifications, drawings, BOMs, and related documentation.

Build, test, and iterate prototypes to achieve robust, production-ready outcomes.

Apply structured engineering methods (PDM, version control, quality documentation,…).

Identify bottlenecks in our current assets and implement hardware or software "upgrades" to boost OEE (Overall Equipment Effectiveness).

Manage and report on own projects with minimal supervision.

Mentor and support junior engineers within the team.

Collaborate across the engineering function to progress multiple projects in parallel.

Lead or support asset care activities on the production line.

Who You Are

Mission-Driven & Ambitious: You’re excited by our "unique" wrapper-free product and see its original challenges as an innovation playground.
The Inquisitive Maker: You don’t just accept the status quo; you ask "why?" and take the initiative to solve problems before being asked.
Ultimate team player: We are a small team with big objectives. Working together, communicating clearly and helping each other will help us succeed.

High Standards & Pride: Whether designing a new mechanism or writing a product specifications document, you care about excellence and efficiency. You know that in production, detail equals safety and quality.

Reliable & Optimistic: You’re a "glass-half-full" teammate who balances a positive attitude with the honesty needed to maintain high performance.

The "Growth" Mindset: You don't just want a job; you want a career. You have a strong ambition to grow your technical toolkit as the business scales, and you want to partake in creating the building blocks of a strong and efficient company.

Culture & The "OGT Way"

One Team: We have a "muck-in" culture. On any given day, you might see an engineer helping production—we win and lose as one team.
Drive & Delivery: We aren't a standard 9-to-5. We value speed and delivery, looking for people who stay until the job is done and proactively seek the next challenge.
In-Person Collaboration: We are an "in-person" team because we believe camaraderie and quick problem-solving happen best together in the workshop.

Growth & Acceleration: This is for those who want to move fast. We want people willing to work hard to achieve shared success and grow their careers.

Qualifications & Experience

Minimum 5 years’ experience as a design and delivery engineer in electromechanical systems, automated manufacturing equipment, or pressurised fluid delivery systems, ideally within FMCG (experience in food coatings, liquid layers,… is a bonus).
Expert user of CAD, with strong experience producing specifications, drawings, and BOMs.
Minimum 3 years’ experience in prototype build and testing.
Minimum 2 years’ experience in completing projects throughout their lifecycle
Desirable: experience in simple electrical system design (wiring, harnesses, panels).
