Help us decarbonize cement and concrete - not tomorrow, today.
alcemy is on a mission to keep 100 million tons of CO₂ out of the atmosphere every year by 2030. Making concrete accounts for around 8% of global CO₂ emissions, and our machine-learning software runs inside cement and concrete plants 24/7 to cut it - without sacrificing quality or driving up costs. We're already live in a third of Germany's cement plants and 30+ ready-mix concrete plants.
The role
As our Full Stack Data Engineer, you'll own the data that powers everything we do - the flow of cement and concrete plant data from raw, messy ingestion through cleaning, to the pipelines our machine-learning recommendations run on. The split is roughly 50% data engineering, 50% backend, and it's refreshingly hands-on with customers: you'll dig into real-world data, explain what you find to non-technical people, and make getting data into alcemy dramatically easier.
What you'll do
You'll thrive here if...
Above all, you care about climate change and want your work to count.

How we work
Our Tech Stack
Our Hiring Process is fully remote
At alcemy, we're building a team as diverse as the industry we're transforming. We welcome applications from everyone and assess every candidate on merit alone - regardless of gender, age, ethnic or national origin, religion or worldview, disability, sexual orientation, or gender identity. We especially encourage people who are underrepresented in tech to apply. If you need any adjustments to take part fully in our hiring process, just let us know and we'll make them.
Note: We don't currently offer visa sponsorship, so you'll need a valid EU work visa.
We provide data-driven technology to enable customers to produce low-carbon-cement and concrete reliably and at scale.
30+ Cement Plants Reached | Integrated in over 50% of German Cement Plants | Concrete is the most widely used building material on our planet. The only thing mankind uses more of is water. With a wave of urban development coming in the next few decades, concrete is also a rapidly growing trillion-dollar market. However, cement and concrete production is responsible for 8% of the global CO2 emissions, making its growth a big cause for concern. Low-carbon concrete exists - but until now it has been too sophisticated to be produced reliably and on a large scale. It contains very little burnt limestone - responsible for the strength of concrete and CO2 emissions. This makes low-carbon concrete vulnerable to fluctuations in raw materials and operating conditions and thus difficult to produce with reliable quality. Adding to the challenge: the final quality of concrete can only be measured weeks AFTER it has been processed on the construction site - far too late to be corrected. This is why our world is still built on more robust, high-carbon concrete. Using alcemy's software, cement and concrete producers receive precise quality predictions already during production. Based on these prediction models, our AI identifies which production parameters need to be adjusted to mitigate the impact of fluctuations. Thus, the quality of cement and concrete can be optimized BEFORE delivery – for the first time in history. The result is significantly more consistent product quality, allowing producers to safely replace burnt limestone with less expensive, low-carbon materials found in nature. In this way, they can also avoid payments for CO2 emission certificates in the EU. Saving costs, bringing production processes up to speed for 21st century concrete recipes, and saving half of Europe’s CO2 emissions goes hand in hand at alcemy. Join us on our journey to make low-carbon concrete a reality!
