• Ensure compliance with relevant standards and regulations (OWASP MASVS, PCI, PSD2, EMV, GDPR) in the SDK design and implementation.
• Establish and oversee robust testing strategies (unit, integration, performance, security testing, static/dynamic analysis, penetration testing).
• Produce clear architecture documentation, API design guidelines, sample projects, and developer-ready integration guides.
• Promote an agile delivery model with regular sprint reviews/demos every ~3 weeks and transparent progress reporting.
• Ensure high-quality developer experience with intuitive API design, comprehensive documentation, and strong support for integration.

Qualifications & Experience

• Deep understanding of proximity communication technologies (NFC, Bluetooth, QR) and secure device-to-device protocols.
• Expertise in secure coding, encryption, secure storage, transaction signing, TEE/secure elements integration; proactive security assessment and threat modelling.
• Strong experience in SDK development: developer-friendly APIs, modular architectures, robust error handling, and secure controls embedded in the SDK.
• Compliance and regulatory knowledge: OWASP MASVS, PCI, PSD2, EMV, GDPR.
• Thorough testing skillset: unit, integration, performance, and comprehensive security testing (including penetration testing, static/dynamic analysis); automated test frameworks.
• Excellent communication skills in English; Swedish is a plus.
• Work part-time on-site in Karlskrona, Sweden, in close collaboration with Ericsson team members.
