Senior Software Engineer (Security experience)

Complexio''s Foundational AI 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 and Símbolo, in partnership with Marfin Management, C Transport Maritime, Trans Sea Transport and BW Epic Kosan.We''re seeking an exceptional security developer to join our efforts in implementing a sophisticated privacy-preserving access control framework across our autonomous business process automation platform.You will need strong Python development experience as you will be building a custom encryption service within a micro-services architecture. The scope covers secure service development, OAuth integrations, and identity provider connections.Key Responsibilities

Design and implement

a comprehensive data privacy and access control architecture that addresses multi-dimensional classification, dynamic permissions, and information barriersFocus on privacy-preserving access controls and coordinate with cross-functional teams including data ingestion, knowledge mapping, and automation developersDevelop and enforce

security and privacy standards, policies, and best practices throughout the product development lifecycleTechnical ImplementationArchitect

a multi-layered access control model combining RBAC, ABAC, and purpose-based limitationsOversee implementation

of fine-grained data classification frameworks using NLP and other technologiesDesign and validate

permission propagation mechanisms for graph data models and derived insightsEstablish security boundaries

for autonomous AI agents, ensuring proper context isolation and privilege controlsCross-Team CoordinationWork closely

with engineering teams to integrate privacy controls into the data pipeline, knowledge graph, and AI componentsCollaborate

with product management to balance privacy requirements with usability and functionalityCoordinate

with customer success to address client-specific privacy and compliance needsInfluence and guide

development teams to prioritize privacy-by-design principles5+ years of experience
