About The Position

We’re looking for a Senior Full Stack Developer who naturally gravitates toward backend systems and infrastructure, but enjoys owning product experiences end-to-end. At CoLab, full stack developers are deeply involved in shaping the product — not just implementing tickets. You’ll work closely with Product, Design, AI, and fellow developers to solve complex technical problems that directly impact how engineering teams collaborate and make decisions. Depending on the team you join, your work could involve building scalable APIs, improving system reliability, designing data-heavy workflows, integrating AI-powered capabilities, or developing intuitive frontend experiences for highly technical users. This is a role for someone who likes difficult problems and meaningful ownership. The work is often ambiguous. Priorities evolve as we learn. You’ll be expected to make thoughtful technical decisions, communicate clearly, and move work forward without waiting for perfect direction. Some developers prefer staying narrowly specialized. That’s not this role. We’re looking for someone who enjoys understanding the full system — from infrastructure and services to the customer experience sitting on top of them.
