RF System Testing:

• Experience using RF test equipment, including High-speed oscilloscopes, Signal generators, RF power meters, Spectrum analyzers, Vector network analyzers (VNA), etc.
• Knowledge on RF principles and measurement techniques, including Signal-to-noise ratio (SNR), Sensitivity analysis, RF power and emission analysis, Interference detection and spectrum analysis
• Experience with WiFi, LTE, RFID or other System Testing is a plus

Da garagem de casa para o mundo: assim começa a história da DB. Nascemos com desejo de mudança, nosso propósito é ser uma empresa de tecnologia centrada nas pessoas, com colaboração, inclusão e diversidade. Em 1993, iniciamos como consultores de um dos grandes bancos de dados da época, que nos deu o nome de DBServer (data base server) e aos poucos fomos construindo a DB (Design + Build the future) que você conhece hoje, a que gera mudança através de inovação e humanidade.

Nós desenvolvemos pessoas que impactam os negócios com tecnologia e inovação, participando de forma flexível e articulada em squads, consultorias e capacitações em todas as etapas do ciclo de vida, do Discovery ao Delivery e sustentação.

Um olhar para a Diversidade & Inclusão

A DB tem constituído uma jornada composta por marcadores culturais com profundo significado humano e que fazem parte do nosso dia a dia. Com coragem e empatia, colaboração, senso coletivo e de comunidade, estamos evoluindo na direção de uma cultura centrada nas pessoas.

Estamos orgulhosos de promover um ambiente de trabalho livre de discriminação. Acreditamos que a diversidade de experiências, perspectivas e histórico transforma nosso ambiente de trabalho. Estamos empenhados a construir esse legado com a sua parceria!
