Job description

Overview

Complexio is Foundational AI. This works to automate business activities by ingesting whole company data – both structured and unstructured – and making sense of it. Using proprietary models and algorithms Complexio forms a deep understanding of how humans are interacting and using it. Automation can then replicate and improve these actions independently.

Complexio is a joint venture between Hafnia, in partnership with Marfin Management, C Transport Maritime, Trans Sea Transport and BW Epic Kosan and Símbolo

Responsibilities

• Partner with sales and leadership to position Complexio’s technology in client meetings, discovery calls, and solution workshops
• Understand client business processes and map those to the platform’s capabilities (ingestion, mapping, knowledge graph, orchestration, agent workflows)
• Define and document the scope of PoCs, pilot programs, and commercial deployments
• Articulate technical concepts (data architecture, infrastructure, security) in commercially relevant language for executive stakeholders
• Assist in the development of proposals, technical diagrams, SoWs, and integration outlines
• Work closely with engineering to ensure solution feasibility and clarity during the sales cycle
• Tailor demos and walkthroughs using real or anonymised data to showcase applied use cases (e.g. lost invoice detection, regulatory process mapping)
• Support conversations on deployment models (on-prem, air-gapped, hybrid) and data governance
• Help refine pricing estimates based on use case complexity and integration requirements

What Success Looks Like

• Trusted by the sales team and Co-CEO to support key deals and strategic conversations
• Confidently handles technical Q&A with both IT leaders and business users
• Accelerates sales cycles by reducing friction around deployment, data access, and technical feasibility
• Wins customer confidence through clarity, responsiveness, and commercial empathy

Qualifications

• 5+ years in a customer-facing technical role (pre-sales, solutions architecture, sales engineering)
• Experience working alongside commercial or executive teams to position complex platforms
• Deep understanding of enterprise data environments — familiarity with APIs, cloud infrastructure (AWS/Azure), IAM, and integration models
• Strong communication skills — equally comfortable with CIOs, compliance heads, and data architects
• Structured, proactive, and persuasive — able to distil core value from complex systems

Preferred

• Background in AI, machine learning, data platforms, or graph technology
• Experience in regulated industries (shipping, energy, finance, supply chain)
• Ability to adapt commercial materials and pitch narratives to different personas
• Familiarity with privacy-preserving architectures, unstructured data processing, or event-based reasoning models

Benefits

• Join a pioneering joint venture at the intersection of AI and industry transformation.
• Work with a diverse and collaborative team of experts from various disciplines.
• Opportunity for professional growth and continuous learning in a dynamic field.
