About Intermedia: Intermedia has established itself as a leading provider of cloud communications and collaboration tech that allows companies to connect better. We have a strong track record of growth, profitability, and creating an environment where everyone matters. While we are fast-paced and admittedly a bit intense, we promise that you won’t be bored.

Culture at Intermedia is built on teamwork and transparency. We hold each other accountable and always have each other’s back! While primarily remote, this role requires occasional visits to the office in Coimbra. We plan to open offices in Aveiro and Porto in the future. This approach gives team members the flexibility to work remotely while also coming together in the office for collaboration and teamwork.
