\n

• \nOur engineering team talks directly with our customers. No layers in between.\n

\n

• \nWe work hard and we have fun.\n

\n

The Role

\n

As a Senior Full-Stack Engineer at Conveo, you'll spearhead the development lifecycle for the AI-powered platform, taking ownership of features from initial specifications through deployment. You'll build applications where AI is seamlessly integrated as core technology, not just an add-on feature. You'll stay at the cutting edge of AI capabilities.
A big part of your role will involve direct contact with our customers. Since we have no product managers, you'll be responsible for directly interfacing with clients, understanding their needs, and translating those into technical solutions. This customer-facing aspect is crucial for ensuring we build exactly what solves their problems.
Beyond coding, you'll actively participate in product refinement and brainstorming sessions, directly influencing both what we build and how we build it, making this an opportunity to have significant technical and strategic impact.
