Senior Mechanical Design Engineer

Senior Mechanical Design Engineer
Location: Newmarket
Salary: Up to £65,000 DOE

About the Role

KO2’s client is seeking an exceptionally talented Senior Mechanical Design Engineer to join their elite engineering team in Newmarket. This is genuinely a rare opportunity to work on some of the most exciting and challenging mechanical engineering projects you’ll encounter in your career. You’ll find yourself at the forefront of designing and engineering novel automotive robot systems that are quite literally breaking boundaries in the safety arena.

The role will see you working directly alongside one of the most experienced mechanical engineers on the market, who will serve as an exceptional mentor. This is the kind of technical leadership and guidance that money quite frankly cannot buy, and it’s the sort of opportunity that will genuinely accelerate your professional development in ways that most engineers only dream about.

What You’ll Be Doing

You’ll be responsible for leading the mechanical design function from initial concept right through to successful manufacture. This is not a narrow, specialist role; rather, you’ll be involved in the complete engineering lifecycle. Your primary focus will be to create detailed 3D CAD models using SolidWorks, generating comprehensive technical drawings and system architectures that are both robust and thoroughly thought through. You’ll be running sophisticated structural analysis and finite element analysis (FEA) to understand precisely how systems will perform under real world stresses, vibrations and environmental conditions.

Critically important to this role is your understanding of fabrication, steel construction, welding techniques and bolting strategies. The engineering here is substantial, chunky mechanical engineering, not the sort of lightweight polymeric work you might find elsewhere. You’ll be selecting appropriate materials, evaluating manufacturing methods, and essentially ensuring that everything you design is not just technically sound but genuinely manufacturable by the teams on the shop floor.

There’s also significant work to be done in terms of rework and redesign on the existing platform. We’re looking to take several hundred hours out of the build process through intelligent engineering, which means improving efficiency, reducing production costs, and resolving manufacturing constraints. You’ll be implementing change management protocols, issuing service bulletins, creating and maintaining comprehensive technical manuals, and ensuring absolutely everything meets the rigorous NATO compliance standards required for the end customer.

What We’re Looking For

You’ll have demonstrated, proven experience as a senior mechanical design engineer, with genuine competency in creating robust designs from initial concept through to successful manufacture. Your CAD skills will be exceptionally strong, particularly with SolidWorks, and you’ll have a meticulous understanding of how to create assemblies, components and detailed manufacturing drawings that actually make sense on the shop floor.

You’ll be comfortable applying engineering principles, undertaking calculations, specifying appropriate tolerances, and using FEA to validate your designs. Most importantly, you’ll have genuine understanding of manufacturing processes. You won’t just design in isolation; you’ll understand how things are actually made, cut, welded, and finished. You’ll be knowledgeable about metals and materials selection, and you’ll be able to confidently discuss fabrication, machining, welding, and finishing techniques.

You need to be someone who approaches design challenges pragmatically, who evaluates problems logically and makes evidence based technical decisions. You should be the sort of engineer who takes genuine ownership of accuracy and engineering excellence.

You need to communicate complex engineering information clearly to both technical and non-technical audiences. You should be someone who works effectively with colleagues and manufacturing teams. You’ll need to be proactive, capable of working with appropriate autonomy and without requiring constant hand-holding. You’ll demonstrate sound engineering judgement and professional credibility. We’re looking for someone who is confident to make sound technical decisions and take ownership of outcomes.

Why Join

This is quite genuinely a unique opportunity. The products being developed here are genuinely innovative and internationally significant. The engineering challenges are substantial and genuinely interesting. Your work will quite literally make a difference in the real world, deployed across numerous countries globally. If you’re the sort of engineer who wants to do genuinely meaningful work on genuinely interesting problems, with genuinely good people, then this could be absolutely perfect for you.

Apply Today

If this role appeals to you and you believe you’ve got the technical capability and the right attitude to succeed in this environment, we’d very much like to hear from you. Please send your CV through to KO2 and we can have a proper discussion about whether this opportunity is genuinely right for you.

Senior Software Architect

Senior Software Architect
Royston, Hertfordshire

£90,000 basic + bonus (£100,000 OTE)

On-site with flexibility

Own the software vision for two global product platforms.

This is a rare opportunity to take genuine architectural authority across an entire software ecosystem, not a slice of it. Our client is a global manufacturer of advanced precision machinery used in demanding, highly regulated production environments worldwide. Their Royston site is the global design authority for the product line, supported by manufacturing operations in the United States and China, and R&D teams in the UK, Germany and Asia.

They currently run two established brands, each with its own software platform, its own hardware platform, and its own development team working largely independently. That is the problem you are being brought in to solve. You will be the person who understands both architectures at code level, forms a view on what should be shared, what should be merged, and what should stay deliberately different, and then sets the technical direction that takes those platforms into their next generation.

What you will actually be doing

  • Getting properly under the bonnet of two mature software architectures, mapping how they are built, why they were built that way, and where the structural risks and opportunities sit
  • Defining the technical vision and roadmap for the next generation software platform, aligned to how the business wants to differentiate its two brands commercially
  • Designing layered architectures that allow multiple teams, in multiple countries, to iterate quickly without tripping over each other
  • Producing system architectures and high level product specifications for solutions that must be robust, scalable and secure
  • Line managing a small UK software team of three to four engineers initially, with the German software team of a similar size expected to come under your remit over time
  • Acting as the technical bridge into the Asia based R&D function, particularly around a growing portfolio of AI driven feature development
  • Working across the full lifecycle, from early system definition through design, development, deployment and production support
  • Holding developers to account on implementation quality, challenging approaches and mentoring where it counts
  • Operating within an established Agile framework (SAFe or Scrum)

The portfolio you will influence spans customer facing application software, advanced imaging and signal processing algorithms, embedded firmware on custom electronics, and internal production and R&D tooling.

The technology

The core application software runs on Windows IoT and is predominantly C and C++, with C# also in the estate. Around it sit custom electronics with their own firmware and embedded operating systems, AI and machine learning workstreams, and an emerging interest in connected and cloud enabled services. Cyber security, and the Cyber Resilience Act in particular, is a live and serious topic, because these are connected products going into industrial networks.

What they need from you

This is not a requirements engineering role and it is not a Scrum Master role with a new title. The team will only follow someone whose technical credibility is beyond question.

Essential:

  • A career that started in hands on software development and progressed upwards. You do not need to code daily, but you must be someone who could, and who has been genuinely excellent at it at some point
  • Strong commercial development background in C, C++ and C#, with exposure to Python, .NET, Java or SQL welcome
  • Experience architecting software that controls physical hardware. This is not enterprise software. The code drives a machine that does something in the real world, and it has to interact properly with electronics, sensors and mechanics
  • Demonstrable experience operating as a software architect or technical authority within a complex, multi site organisation
  • The ability to influence, persuade and align global teams without direct line authority
  • Domain depth in at least one of: application software (industrial automation, networking protocols, UI frameworks), IoT and cloud development (Azure, AWS), AI and machine learning systems, cyber security, or embedded systems (RTOS, bare metal, hard real time)

Highly desirable:

  • Experience working across European, Asian and North American teams, and an instinct for how working and communication styles differ across those cultures
  • Time spent living or working abroad
  • Background in industrial automation, medical devices, robotics, defence or another regulated hardware led sector

Travel and working pattern

Expect to travel less than twenty percent of your time, but at least once a quarter, including regular trips to Germany and roughly quarterly visits to Asia. The role is primarily site based in Royston, with a discretionary hybrid policy in place.

What is on offer

  • £90,000 basic salary
  • Annual bonus scheme taking realistic total earnings to around £100,000
  • 25 days annual leave plus bank holidays
  • Early finish on Fridays
  • Enhanced work life balance policies, strong wellbeing focus and regular employee engagement events
  • Genuine international exposure across a global engineering network
  • Committed investment in training and technical development

Why this one is worth a conversation

Architect roles of this scope do not come up often. Most give you one platform, one team and a fixed direction. This gives you two platforms, three engineering locations, a blank sheet for the next generation, and the mandate to decide what it looks like. If you have built the technical foundation and you now want the influence that goes with it, this is the step.
