IDEMIA · Poland

• Define architecture and technical direction for enterprise eUICC/SIM platforms, integrations, reporting capabilities, and production services.
• Act as a hands-on technical expert for complex and business-critical work, including major feature design and deep implementation guidance.
• Lead critical production-bug and escalation response, coordinating investigation, remediation, implementation, testing, integration, validation, and safe release.
• Maintain delivery continuity during smaller production incidents, preventing operational issues from unnecessarily derailing planned work.
• Apply a problem-first, language-agnostic approach to unfamiliar applications and technology stacks requiring diagnosis, modernisation, repair, or stabilisation.
• Built, hired, trained, and mentored an engineering team while establishing technical standards and collaborative delivery practices.
• Increased delivery from 1–2 to 5–8 features per release while the team approximately doubled in size—an estimated 2–3× increase in per-engineer productivity despite greater product complexity.
• Lead solution design from business requirements through technical design, stakeholder alignment, implementation delegation, and hands-on delivery of deep or high-risk functionality.
• Coordinated and supported major Cosmos DB customer migrations.
• Collaborate with architects, technical leads, SRE, and deployment teams on high availability and technical design.
• Serve as security champion, conducting OWASP-oriented analysis and orchestrating remediation of findings from OWASP reviews and Sonar.
• Perform functional and technical risk assessments for features and releases, covering access restrictions, cloning, outages, deployment risks, and operational continuity.
• Partner with security leadership and delivery stakeholders to establish technical, functional, deployment, and organisational security controls.
• Drive architectural decisions concerning incremental delivery, simplification, maintainability, resilience, and long-term platform evolution.
