The short version

You’ll design and work with the ground systems that make airship operations actually work. From containers and field hangars to tools and hydrogen infrastructure, you’ll take responsibility for all mechanical structures that support operations on the ground, and make them safer, more usable, and easier to operate.

About Kelluu

We are turning the real world into a digital one, with accuracy down to the smallest detail. Imagine a near future where everything you see can be explored through data delivered by Kelluu, and where AI works continuously across that data to find what you need to know. Everything turned into answers.

We’re a Finnish deep-tech company, headquartered in Joensuu with offices in Helsinki and Tampere. The team is growing fast, the goals are ambitious, and we’re hiring people who want to build something that matters.

Our technology is flight-proven and operational. We’re a NATO DIANA Phase 2 alumni with several thousands of hours of autonomous BVLOS flight experience, active programmes across multiple NATO nations, and a rapidly growing team. We operate in both defence and civilian markets: the same technology that supports border security also monitors critical infrastructure and the environment.

P.S. We just raised 15M€ Series A.

Why this role exists

Our operations are growing and ground systems need a dedicated owner who can see the whole picture, design the steel and structures, and turn operational needs into robust, real-world solutions.

Our airship platform is moving into real-world operations where reliability, safety, and speed of deployment matter as much as the aircraft itself.

This role exists to take full ownership of the ground systems that make those operations possible—from containers and field hangars to hydrogen infrastructure. The goal is not just to design individual structures, but to define a ground station concept that is safe, usable, mobile, and easily replicable across locations.

What you’ll own

The impact you’ll have:

• Designing steel/aluminium structures and mechanical systems for ground operations, including containers, field hangars, tools, and supporting equipment

• Taking care of ground station concepts, from semi-permanent setups to fully mobile systems used in exercises

• Designing and improving hydrogen-related ground infrastructure, including handling, storage, and refuelling of pressurised hydrogen tanks

• Defining what equipment, tools, and structures ground stations need — and how everything is stored, organised, and used

• Designing custom tools, handling equipment, and support structures tailored to operational needs

• Developing detailed modifications to existing containers and systems, including usability improvements such as redesigned sleds for moving airships in and out of containers

• Improving final assembly setups and workflows at the Reijola site through practical mechanical design updates

• Ensuring ground systems serve the operations team in real life: they work reliably, stay organised, and make operations smoother instead of harder

Your team

You’ll work closely with a small, experienced mechanical and electrical engineering team spread between Joensuu and Tampere. Day to day, you’ll collaborate with mechanical and electrical designers, and colleagues responsible for safety, documentation, and flight operations. The atmosphere is hands-on, practical, and informal — designs move quickly from CAD to workshop to testing.

What success looks like

By 3 months, you will have:

• Taken ownership of existing 3D design

• Become comfortable with our tools, materials, and development rhythm

By 6 months:

• Independently designing and iterating new mechanical structures

• Keeping mechanical documentation accurate, useful, and up to date

By 12 months:

• Fully owning lightweight mechanical design for key airship subsystems

• Improving design-for-manufacturing practices

• Being a go-to person for practical, lightweight mechanical solutions

What we’re looking for

You’ll thrive here if you have:

• At least few years of experience in mechanical design or structural engineering

• Strong 3D CAD skills (Inventor or similar)

• Experience with mechanical design for durability

Even better if you also bring:

• Knowledge of different materials and working with them

• Background in aviation, robotics, or other weight-critical systems

What you get

The opportunity:

• Hands-on involvement in design, manufacturing, and testing

• Dive deeply in our mechanical designs

• Direct influence on how our platform develops

The practicalities:

• Salary range: €3,500–4,300/month, depending on experience

• Healthcare, Lunch benefit, Culture, sports, and wellbeing benefit (Epassi), Phone

• The tools you need to do your best work

• Flexible work culture — results matter more than desks

The kind of place this is

Kelluu is a dual-use deep-tech company at the intersection of autonomy, AI, and aerial intelligence. We build technology that serves both national security and society, and we take that responsibility seriously.

We’re scaling fast, which means you’ll have real influence on how things are built. The flipside: things move quickly, priorities shift, and everyone wears a few hats. If you want a finished playbook and a clear lane, this probably isn’t the right fit. If you want to write the playbook yourself, it might be exactly right.

We use AI tools extensively, not as a gimmick, but because it lets a growing team move faster than anyone expects. We expect everyone to be curious about how to work smarter.

Details
