About Dioxycle

Dioxycle is pioneering breakthrough carbon utilization technologies that convert industrial emissions into sustainable chemicals with unprecedented energy and cost efficiency. By displacing fossil fuels for the production of key chemicals, Dioxycle has the potential to ultimately reduce over 800 million tons of CO2 per year, representing over 2% of the world's emissions.

At the core of our process is a novel "carbon electrolyzer", a machine capable of using just electricity and water to convert carbon emissions back into valuable everyday essential chemicals. Our team is innovating across chemical, mechanical and system engineering to turn carbon transformation into an economically feasible, industrial reality through this completely novel technological approach. Having completed our medium-scale Proof-of-Concept electrolyzer, we are now working towards a first-of-its-kind large-scale industrial prototype and are assembling key partnerships for future commercial roll-out.

We are supported by world-class funders including Lowercarbon Capital, Breakthrough Energy Ventures and Gigascale Capital and have raised $37M to date. We operate from two centers in Paris and California (so whether you are passionate about outdoors or good food/art scenes, we have a location for you to join!)

Schibsted

Oslo•Posted: Apr 8•Deadline: Aug 16

Job description About the role/team Independent journalism and free speech depend on people being able to do their work without being watched, hacked, or silenced. That's where this role comes in. Based across Sweden and Norway, our security team designs, builds, and maintains the cybersecurity tools and services that protect Schibsted, our journalists, and the products we deliver to our customers. We work closely with the rest of the organisation: journalists, editors, IT, AI, legal, infrastructure, network, and collaboration software teams. What you will be doing In this role, you will split your time between two missions: building the security infrastructure that protects the company, and working directly with journalists, including those operating in high-risk environments in order to keep their sources, communications, and digital assets safe. * Design and implement security systems and architecture: network segmentation, firewalls, IDS/IPS, VPNs, endpoint protection. * Work with journalists and editors to assess and reduce risk in their workflows, communications, and equipment. Including support for missions in the field. * Build security protocols that protect journalistic content and communications from unauthorised access, interception, or tampering. * Lead incident response together with our NOC and SOC — threat hunting, investigation, and digital forensics. * Run security assessments and turn findings into concrete risk-reduction strategies. What we are looking for * Academic background in cybersecurity, computer science, or similar. * 1–3 years in an IT security role, with hands-on experience implementing security controls and tooling. * Working knowledge of SIEM, EDR, DLP, and vulnerability scanning tools. * Solid grasp of networking, operating systems, and cloud platforms. * Comfort communicating with both technical and non-technical stakeholders. The position is based in Oslo and requires regular interactions with journalists. Fluency in English and Norwegian is required. What we offer you: You will join a young team where the work is real from day one. There is room to take ownership, shape how we do things, and grow fast. And the work matters, what we do keeps journalists and their sources safe and help keep free speech protected. ABOUT THE COMPANY Independent Journalism – That’s our business Schibsted Media Group includes some of the strongest media brands in the Nordics, including VG, Aftenposten, E24, Bergens Tidende, Stavanger Aftenblad, Aftonbladet, Svenska Dagbladet, Omni, and Podme. Every day, nearly seven million people turn to our editorial media to stay informed, engaged, and entertained through text, audio, images, and video. The trust of our users is crucial to us. To maintain this trust, we prioritise truth, verifiability, and transparency. Our 2,800 employees are based in Oslo, Bergen, Stavanger, Stockholm, Helsinki, Krakow, and Gdansk. We rely on all of them to succeed, through close collaboration across editorial teams, product and technology environments, and subscription and advertising units. What began as Christian Schibsted's small printing business in Christiania (now Oslo) in 1839 has grown into one of the leading media companies in the Nordics. For nearly two centuries, our journalism has empowered people, built communities, exposed abuses of power, and strengthened democracies. Our democracies depend on independent journalism. That’s our business.
