Arkeusbuilds AI-powered sensing systems that help autonomous platforms detect,trackand understandwhat'shappening in the most complex and contested environments. Our technology is deployed across defence and national security applications — already protecting lives and strengthening security across the U.S. and allied markets.

Backed by QIC, Main Sequence, R+VC, Salus Ventures, Folklore Ventures, DYNEVenturesand Beaten Zone Venture Partners,Arkeusis entering a major growth phase. We are a small, fast-moving company with the energy and ambition of a start-up and the technical credibility of a world-class defence technology provider.

We work at the intersection of optics, autonomy, robotics and real-time AI and we deploy what we build. If you want to build technology that gets deployed in the real world, not technology that stays on the roadmap, this is where you belong.

About the role

As a Senior Mechatronics Engineer atArkeusyou will lead the development of technologies that redefine what is possible in autonomous sensing and optical radar systems.

You will own critical decisions spanning architecture, design, integration, and validation of advanced prototype systems, influencing outcomes from component-level innovation through to mission-level capability. Few engineering roles offer this combination of system-wide impact and hands-on technical depth—one day shaping the future direction of a multi-disciplinary program, the next solving a challenging problem in optics, mechanisms, electronics, or control systems.

Working directly with the CTO and Product Owner,



you will help transform ambitious concepts into operational reality while mentoring exceptional engineers and building the foundations of future products. For those motivated by meaningful technical challenges, genuine ownership, and the opportunity to create capabilities that matter this is a career-defining opportunity.

Key responsibilities

- Partner with the executive leadership team to understand product and prototypeobjectives,prioritiesand requirements.
- Lead the design of products and prototypes from concept through tovalidatedbuild.
- Select materials,componentsand suppliers to best meet product requirements.
- Assemble, integrate,testcomponentparts to all-up assemblies.
- Design and lead field-environment test events for prototype product systems.
- Support the manufacturing and testing of products and prototypes.
- Work with the engineering team to transform prototypes into high-quality, production-ready products.
- Present, review,andcompiletheproducts ofthesystems engineeringprocess.
- Coach and mentor the engineering team.
- Communicate risks, issues and dependencies to the Project Manager and leadership.

Your experience and skills

Required:

- Engineering degree in Mechatronics, Mechanical, Electrical, Aerospace,Navalor a related discipline.
- 7+ years in mechatronic/electro-mechanical product development.
- Experience designing systems incorporatingmechanical components, actuators, PCBs,andelectronicswithinan integrated CAD setting.
- Experience designingactuatorcontroller electronics andfirmwarecontrol loops.




- Experience with embedded systems and microcontroller programming (e.g. STM32).
- Strong knowledge of kinematic and dynamic mathematical modelling.
- Able to compile BOMs and source components.
- Ability to travel domestically as neededto support field test events.

Nice to have:

- Knowledge ofreal-time sensor signal conditioning, management, andsizing.
- Knowledge in and experience withfirmware, driver, device-tree, and kernel development.
- Experienceleading arapid prototypingproject.
- Experiencewith FPGAintegration, bitstream loading, and Verilog.

Why Join Arkeus

- You will work on the hardest problems in deep-tech — optics, autonomy, real-timeAIand hardware-software integration ina single product. The gap between what you build and where it ends up is almostnon-existent.
- You will collaborate with exceptional leaders who have 40+ years of combined experience in autonomy,opticsand defence. You will be learning from — and contributing to — the best in the field.
- You will become part of a close-knit, ego-free team where ideas compete on merit, not seniority. Low politics, high trust. The kind of team you will still be talking about in ten years.
- You will work hard and be expected to bring your best — and in return, you will grow faster than you ever would at a large organisation.
- You will work on technology that is already deployed in real environments — protecting lives and strengthening security across defence and national security applications.
- You will receive a competitive, market-benchmarked salary, structured career pathways built to grow with you, and the opportunity toparticipatein our Employee Share Option Plan (ESOP).
- You will have the opportunity to mentor bright emerging talent through our highly sought-after intern program and strong connections with leading universities.
