ABOUT AHBSTRA
We build machines that make drinking water out of air. Our systems uses refrigeration cycles and metal-organic frameworks (MOFs) to capture atmospheric moisture and produce water even in the driest atmospheric conditions.

THE ROLE
You will be part of designing and testing our air-to-water machines. You will also build the test rigs we use to screen new MOF materials — the data they generate is what optimises our current and future machines.
You will support prototyping, testing, and validation. You will generate and run test plans, analyse performance data and iterate designs to improve reliability, efficiency, and manufacturability.
This is a full-time, on-site role in Cerdanyola del Vallès, Barcelona.

WHAT YOU WILL DO
Design mechanical assemblies, sheet metal parts and bespoke composite panels
Run day-to-day testing: instrumentation, data capture, teardown, iterate




Design and build test rigs to characterise new MOF sorbent materials
Diagnose real hardware — airflows, heat transfer, adsorption/desorption performance of our machines
Manage assembly technicians
Take designs from sketch to fabrication drawings to assembled units
Work with suppliers to reduce BOM costs
Work with workshops to fabricate parts and prototypes

WHAT WE NEED
Degree in mechanical engineering, or equivalent experience
Strong CAD skills (preferably SolidWorks)
Hands-on. You are comfortable with tools, assembly, and instrumentation
Good level of English
Right to work in Spain

NICE TO HAVE
Thermodynamics: understanding of psychrometric charts, heat pumps, refrigeration cycles, heat exchangers
HVAC or refrigeration experience
MOF knowledge
