Lead Architect – Cross-Border Business Unit

Role Summary

We are seeking a seasoned Lead Architect to drive strategic architecture initiatives across a fast-growing Cross-Border business unit. This role focuses on assessing and shaping the technology landscape for cross-border operations, and designing a modern data platform and digital services ecosystem.

The ideal candidate brings deep expertise in enterprise architecture, transport systems, data platforms, and microservices-based product organizations — with the ability to translate business needs into scalable, secure, and future-proof technical solutions, while inspiring teams and stakeholders around a clear architectural vision.

Key Responsibilities

Architecture Leadership

  • Assess and document the current technology landscape for cross-border logistics and transport platforms

  • Define scalable, secure, and modular reference architectures for logistics, transport, and digital services

  • Lead the design of a modern data platform architecture (lakehouse, data mesh) and define key data products

  • Support the definition of architecture for e-commerce integrations and API digital services

Platform Development & Guidance

  • Create and review technical designs for coherence, scalability, and resilience across domains

  • Guide the adoption of microservices and product-centric architecture models

  • Provide architectural support for event-driven architecture (EDA) initiatives, including Kafka-based event streaming and schema governance

Collaboration & Governance

  • Work closely with product owners, developers, and business analysts to translate business requirements into technical architectures

  • Collaborate with suppliers and remote teams to ensure cross-functional alignment and delivery

  • Contribute to architecture governance and quality enablement across teams

Innovation & Best Practices

  • Stay current on advancements in cloud-native technologies, data platforms, and e-commerce ecosystems

  • Ensure compliance with data security standards and establish governance practices for APIs and schemas

  • Promote architectural best practices across teams and domains

Candidate profile

Experience

  • 15+ years in enterprise or solution architecture, with experience across logistics, transport, or e-commerce domains

  • Proven experience designing and implementing data platforms (Snowflake, Databricks), microservices architectures (Java, PHP, Python), and API ecosystems

  • Exposure to EDA principles and technologies (Kafka, Avro, schema registry) is a plus

  • Experience with AWS (Lambda, DynamoDB, S3, RDS, SQS, SNS, CloudWatch); Azure exposure is a plus

  • Experience with DevSecOps practices and secure software development lifecycles

Technical Skills

  • Strong understanding of product organization models and domain-driven design

  • Experience with API-driven architectures (RESTful APIs, API gateways)

  • Proficiency in containerization and orchestration tools (Docker, Kubernetes, AWS ECS/EKS)

  • Familiarity with data mesh, lakehouse architectures, and data governance principles

Soft Skills

  • Excellent communication skills with the ability to translate complex technical concepts for business stakeholders

  • Strategic thinker with strong analytical and problem-solving capabilities

  • Proven leadership, including guiding and mentoring development teams

  • Inspirational leader who motivates teams, builds confidence in architectural direction, and drives adoption through vision and influence rather than authority

Languages

  • Business-level English is required (written and spoken); additional European languages are a plus

Preferred

  • Prior experience in logistics, transport, and e-commerce platforms is a strong plus
