The Application Integration Engineer – CDO is responsible for advanced application delivery, integration, and release activities within the Client Delivery and Operations (CDO) function.

This role acts as technical owner for client-specific application variants and integrations, with a primary focus on mobile applications, while also supporting other platforms as required. The role bridges operational execution and engineering coordination, without owning feature development.

Key Responsibilities

•    Own and execute application build, signing, and release activities for client-specific application variants.
•    Manage application store submissions and reviews (e.g. Apple App Store, TestFlight, Google Play) for client builds.
•    Coordinate certificates, provisioning profiles, signing keys, and release artifacts.
•    Generate and validate application binaries across platforms using CI/CD pipelines (primarily Jenkins).
•    Lead the integration of third-party applications and services with company applications at configuration and system-integration level.
•    Own the lifecycle of client-specific integrations, including validation, deployment, and operational readiness.
•    Coordinate closely with Engineering for dependencies, limitations, and handovers where code changes are required.
•    Act as escalation point for complex application issues beyond standard L1 support.
•    Perform advanced troubleshooting of mobile and application-level issues across Android, iOS, and other supported platforms.
•    Analyze logs, network traces, and runtime behavior to identify root causes and propose resolutions.

•    Operate and maintain application build and release pipelines, including:
•    Triggering builds
•    Debugging pipeline failures
•    Making light adjustments to scripts and job configurations
•    Ensure build and release processes are repeatable, auditable, and aligned with operational standards.
•    Ensure application builds adhere to platform security requirements and internal security baselines.
•    Apply secure boot and application hardening principles during build and release activities.
•    Validate application artifacts against basic security and integrity requirements before release.
•    Work through CDO and Project Managers for planning, prioritization, and client delivery activities.
•    Coordinate closely with Engineering, QA, and Security teams to ensure smooth handovers and clear ownership boundaries.
•    Maintain clear documentation for integrations, releases, and operational procedures.

Education and Minimum Qualification

•    Bachelor’s degree in Computer Science, Information Technology, Engineering, or a related field.
•    Minimum 3–5 years of professional experience in application delivery, integration, advanced application support, or related roles.
•    Hands-on experience supporting mobile applications, with Android as the primary platform.
•    Proven experience with application build, signing, and release processes in production environments.
•    Experience working in operational or delivery-focused teams supporting client environments.

Key Skills

•    Technical Skills:
o    Strong understanding of Android platform fundamentals, including Secure Boot and Android Verified Boot, Application hardening and integrity concepts (such as AOSP, LineageOS, GrapheneOS, etc.)
o    Hands-on experience with mobile application build and submission processes (Android and iOS).
o    Working knowledge of CI/CD tools, particularly Jenkins, for application builds and releases.
o    Proficiency in scripting and programming languages (Bash, Python, Java).
o    Good understanding of networking fundamentals and protocols.
o    Experience using troubleshooting and analysis tools such as Wireshark,tcpdump, Burp Suite or equivalent tools.
o    Basic understanding of applied cryptography concepts and application hacking (frida, apktool, jadx, etc.)
•     Non-Technical Skills
o    Strong operational and delivery mindset with high attention to detail.
o    Pragmatic problem-solving approach with a strong sense of ownership.
o    Ability to operate effectively under delivery pressure and shifting priorities.
o    Ability to work effectively as part of a team.
•     Certifications (Preferred):
o    Android Certified Application Security Engineer (CASE) 
o    Offensive Security Mobile (OSCP Mobile / equivalent mobile-focused training)
