Design and optimise the processes that make our plants run, from feasibility studies and simulations through to commissioning and operation.
Infiniteria is a growing company on a mission to make tyre production sustainable. We are building industrial solutions that make circularity profitable, scalable and real.
Our mission is clear: to transform end-of-life tyres into high-value materials for new tyres and fuels, enabling circular material loops at industrial scale — without compromising on economics, safety or industrial-grade engineering.
Infiniteria combines the pace and ownership of a young company with the discipline that large-scale industrial projects require.
As a Process Engineer you contribute to high-value process design solutions for production plants converting end-of-life tyres into marketable products, supporting production and quality objectives while ensuring compliance with industrial standards for safety, environmental protection, engineering integrity and plant availability.
This is a hands-on technical role in an early-stage environment, with real influence over how our facilities are designed, built and operated.
What you will do
- Ensure technical integrity of process design and optimise process solutions
- Design plant processes with focus on pyrolysis, oil and gas processing and utilities
- Support development of feasibility studies, functional specifications and Basis of Design documents
- Develop and verify process simulations, block flow diagrams, PFDs, P&IDs and mass and heat balances
- Prepare equipment lists and datasheets and contribute to cost estimation
- Perform technical integrity and HSE reviews and participate in hazard identification and HAZOP activities
- Support commissioning, start-up and plant operation, and provide technical support to O&M teams
What we are looking for
- Engineering degree
- 5+ years of experience in chemical, electrical or oil & gas plants
- At least 3 years of experience in pyrolysis or hydrocarbon processing studies
- Experience from industrial production plants and exposure to project management
- Good communication, organisational skills and risk awareness
- Fluency in English and eligibility to work in Sweden
What we offer
- Early-stage influence on decisions that define how our plants work for years to come
- Technically meaningful work: pyrolysis at industrial scale is a genuine engineering challenge
- Small team and short decision paths — your input matters and gets heard
- Competitive compensation and benefits aligned with the seniority of the role
