Job description

Complexio’s Foundational AI platform automates business processes by ingesting and understanding complete enterprise data—both structured and unstructured. Through proprietary models, knowledge graphs, and orchestration layers, Complexio maps human-computer interactions and autonomously executes complex workflows at scale.

Established as a joint venture between Hafnia and Símbolo—with partners including Marfin Management, C Transport Maritime, BW Epic Kosan, and Trans Sea Transport—Complexio is redefining enterprise productivity through context-aware, privacy-first automation.

We’re looking for a senior UX lead, hands‑on with prototyping and product development, who can shape the vision of our NLP products while delivering at startup speed. This is not a traditional UX role—you’ll be embedded with product, data science, and engineering teams, driving design from idea to prototype to product.

What You’ll Do

• Lead a design vision: define and communicate bold, user‑centric product concepts that break new ground.
• Prototype fast—turn abstract ideas into tangible experiences that inspire stakeholders and guide development.
• Work directly with data scientists and engineers to translate raw capability into elegant, usable products.
• Operate with urgency, iterating quickly in a high‑stakes startup where traction means success and growth.
• Influence and persuade—sell your ideas to leadership and rally teams around them.

• Senior‑level design experience with proven ability to set direction and drive execution.
• Comfort working in code‑adjacent environments: not a software engineer, but fluent enough to leverage AI‑assisted coding and emerging design workflows to accelerate prototyping.
• Awareness of industry shifts: you already adapt your process to new AI‑driven methods of product development.
• Deep curiosity about NLP and emerging LLMs, and how they reshape user experiences.
• Startup mindset: resilient, fast‑moving, and motivated to create impact without waiting for direction. This isn’t a corporate job—you can’t hide in a cubicle here.

• Work with a groundbreaking AI platform solving real enterprise pain points
• Help clients achieve measurable ROI through next‑gen automation
• Join a remote‑first, globally distributed team backed by industry leaders
• Shape the success function and influence product direction in a fast‑scaling AI company
