At Colorifix, we're leading the way for a sustainable future by challenging one of the most environmentally damaging industries in the world, the textile dyeing industry. We're pioneering the production of sustainable and non-toxic dyes at scale, using fermentation technology to produce colorants from microbes.

To achieve this, we've relied on the collaboration of an amazing team of experts to develop the strains, fermentors, and digital tools specifically designed to operate in dye-house environments.

To assist business operations at client sites, Colorifix has developed an IoT-powered digital platform (Colorifix Webclient) that collects and visualizes fermentation data in real-time. This enables data-driven insights, process control, and monitoring for clients, while helping us create new products and improve existing ones.

We're looking for an experienced Senior Full Stack Engineer with a minimum of 5 years' experience to maintain and evolve our Colorifix Webclient platform at CFX Biotech, our Portuguese subsidiary, where our main operations are based. You'll have technical authority over the platform, working closely with stakeholders and clients to ensure alignment with business goals.
You'll be responsible for making architectural decisions, designing solutions to complex technical problems, and ensuring reliability and scalability as we grow. You'll also be hands-on daily, writing code, optimizing databases, debugging production issues, and maintaining CI/CD pipelines.
The ideal candidate is someone with a strong engineering mindset, excellent communication skills, and the ability to convey technical concepts to non-technical stakeholders while cooperating effectively within a business context and with multidisciplinary teams.

We value commitment to continuous learning and rapid adoption of new technologies. As our tech stack evolves, we seek candidates who can quickly master new tools and frameworks.

Collaborate with Systems Administrators on platform requirements and capacity planning
Interface with science and commercial teams to understand requirements and validate solutions to improve Webclient
