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.

• Proficiency in scripting and programming languages (Bash, Python, Java).
• Good understanding of networking fundamentals and protocols.
• Experience using troubleshooting and analysis tools such as Wireshark,tcpdump, Burp Suite or equivalent tools.
• Basic understanding of applied cryptography concepts and application hacking (frida, apktool, jadx, etc.)
