About us
At Renasens we're building for people who are energized by winning, enjoy ownership, and thrive in a fast-moving environment. Our pace demands individuals who hold themselves to a high standard and care deeply about execution.
If you prefer extensive structure, highly predictable environments, or a slower pace of decision-making, we may not be the right fit.
In a small team, there's nowhere to hide-in both directions. Great work gets noticed, and so do opportunities to improve. The upside is that your impact is visible, your contributions matter, and strong performance is recognized quickly.
Before applying, take a moment to consider whether this environment aligns with how you do your best work.
Your mission at Renasens
You see a chemical process and instinctively want to understand it in detail; not just whether it works, but why. You will bring a methodical mindset and real attention to detail, taking full ownership of the cotton pre-treatment and dye removal workstream. You are comfortable designing experiments from first principles, running them rigorously, and turning data into decisions that move the process forward.
Take end-to-end ownership of the cotton pre-treatment and dye removal development
Design, run, and iterate on lab scale experiments from bench to pilot relevant conditionsIndependently execute a full suite of characterization techniques
To be able to work in a team, receiving feedback and improving the process
Process, analyze, and report data with the rigor needed for scale up decisions
Refine experimental protocols and SOPs to ensure consistent, high-quality results
Contribute to an organized and clean lab environment
What you bring
MSc or PhD in physical chemistry, chemical engineering, or related field; we particularly value candidates who combine fundamental understanding of dye-fiber chemistry with hands on process development experience.
Industry experience is required
Understanding of the fundamentals in solvation thermodynamics, adsorption/desorption equilibria, kinetics, and mass transport is a merit.
Experience with cellulose, dyes, polymers, or extraction processes is an advantage; bonus if it touches supercritical fluids or alternative solvents
Hands on lab experience; comfort moving between bench work and process thinking
Experimental design skills
Who you are
Energized by problems; yours, your colleagues' and the ones nobody asked you to solve yet. You don't walk past a challenge, you walk toward it.
Reliable & Independent: you take ownership and deliver on time without needing close supervision
Team over ego: you care more about collective wins than being right
Thrive in fast paced environments: you are energized by ambitious timelines and meaningful challenges
Translate depth into action, you go deep on mechanism when needed, but don't get stuck there. You know when to stop characterizing and start deciding.
Great to have, but not required
Experience with industrial dyeing chemistry
Previous experience in textile, fiber, or cellulose-based recycling processes
Sub-critical or supercritical experience
Experience translating lab results into pilot-scale process design
How we work at Renasens
Onsite & hands on: Our pilot plant is in Borås, with our headquarters in Stockholm. This role is based where the work happens; close to the lab and the pilot, not behind a laptop.
Expect to spend most of your time on site running experiments and iterating with the team.
Small team, high ownership: We are around 10 people. You will own your workstream end-to-end and work directly with the R&D lead, process engineers and CEO. No layers, no committees.
Pace matters: We have pilot reception milestones in 2026 and customer commitments behind them. We move fast, decide with the data we have, and iterate.
