Why This Job is Featured on The SaaS Jobs
Optibus operates a complex, AI-enabled SaaS platform used by public transportation agencies, placing product design close to high-stakes operational workflows rather than purely consumer UX. That context typically demands clarity, consistency, and strong information design—work that matters in enterprise SaaS where adoption depends on usability across many roles and scenarios. A senior designer stepping in on a fixed-term basis signals a team that needs someone who can quickly navigate an established product surface area and contribute without a long ramp.
From a SaaS career perspective, the role offers exposure to the kind of systems thinking that transfers well across B2B platforms: designing for repeatable workflows, balancing user research with delivery constraints, and contributing to design-system scalability. Working alongside product and engineering on end-to-end initiatives also aligns with how mature SaaS teams ship—iteratively, with validation and measurable improvements over time.
This position suits a designer who is comfortable joining midstream, integrating into existing processes, and making pragmatic decisions with incomplete context. It will appeal to professionals who prefer platform complexity, collaborative product development, and on-site cadence in Berlin, while still valuing the defined scope of a temporary engagement.
