Build what
actually matters.
We are solving one of the hardest problems in autonomous systems — reliable navigation and perception when every external signal is gone. If that is the problem you want to work on, read on.
Hard problems.
Real stakes.
Most autonomous systems assume GPS is available. We assume it is gone. That single constraint changes everything — the algorithms, the hardware, the architecture, the validation methodology. There is no off-the-shelf answer to what we are building.
The technical depth here is genuine. Terrain-referenced navigation fused with inertial sensing, running on microcontroller hardware. Embedded perception across visual and infrared modalities, optimized to run in milliwatts. Models developed and trained on dedicated EU sovereign compute, then hardened for deployment on hardware with no GPU and no cloud.
The platforms this work goes into are not demos. They operate in contested environments where the quality of the navigation and perception stack has real operational consequences. That is the bar we build to.
Development and validation happen in Finland — which means testing in conditions most programs treat as edge cases. Snow, low sun angles, dense canopy, Arctic winter. If it works here, it works where it needs to.
32× NVIDIA B200 and 16× A100 GPUs, 2,500+ CPU cores, 15+ PB storage — all in Finland, all under EU jurisdiction. You are not waiting for cloud credits or sharing compute. The infrastructure is ours.
Founded by the inventor of SSH. A Head of BD who served as a Duty Officer in a NATO peacekeeping Battle Group HQ. Supply chain leadership from Nokia and Microsoft. We have built at scale before and we know the difference between a prototype and a deployable product.
Two areas.
One mission.
Algorithms, models,
and embedded systems.
You will work across the full software stack — from navigation algorithms and sensor fusion pipelines to model development, optimization, and embedded deployment. The constraint is always the same: it has to run on a microcontroller, it has to work when there is no signal, and it has to be correct under field conditions that lab benchmarks do not capture.
This is not a role where you tune hyperparameters on a benchmark dataset. The feedback loop runs from algorithm to embedded hardware to field performance in Finnish winter. The work is hard in the right ways.
Terrain-referenced positioning and inertial fusion · Computer vision and sensor fusion for denied environments · Model architecture design for MCU deployment · Training pipelines on EU sovereign GPU infrastructure · Quantization, pruning, and hardware-aware optimization · Embedded C/C++ integration and real-time performance
Strong fundamentals in algorithms and systems. Experience with constrained compute environments. Comfort working across the hardware-software boundary. Production experience over research fluency — though both is ideal. Curiosity about why something fails in the field, not just whether it passes the test.
Embedded systems
for the field.
You will design and bring up hardware that runs the full navigation and perception stack in environments it was not designed to fail in. The power budget is tight, the form factor is constrained, and the operating conditions are demanding. The design discipline that comes from those constraints is the job.
You will work closely with software to define the hardware-software interface from the start, not after the fact. The goal is hardware that makes the algorithms easier to deploy correctly — not hardware that the algorithms have to work around.
MCU-based system design for navigation and perception · Sensor integration — IMU, optical, infrared, altimetry · PCB design for low-SWaP tactical platforms · Thermal management and environmental hardening · Hardware-software co-design with embedded firmware teams · Bring-up, debug, and field validation
Experience taking hardware from prototype to production. Comfort with constrained SWaP design. Sensor integration experience across multiple modalities. Understanding of manufacturing constraints and supply chain realities — designs that cannot be produced at scale are not finished. Direct experience with defense or industrial-grade hardware environments is a strong plus.
No forms.
Just a direct conversation.
Send us a note at careers@clausal.com with a brief description of the work you are most proud of and why you are interested in what we are building. We read everything and we respond to everyone who looks like a genuine fit.
A polished CV is less useful to us than a clear explanation of what you actually built, what was hard about it, and what you learned. If there is code, hardware, or published work you want to share, include it.
careers@clausal.comHelsinki, Finland. We work in person. Relocation support is available for the right candidates.
EU work authorization required for most roles given the nature of the programs we work on. Exceptions may apply — ask.
If you are exceptional in a relevant area and the problem genuinely interests you, reach out anyway. We are building a team for the long term, not filling seats for the quarter.
The problem is real.
The team is small.
Early engineers shape what this becomes. If you want to work on something that will outlast you, this is where that work is happening.
