Role Overview
We are looking for an experienced Delivery Manager to own end-to-end delivery of a client migration and platform upgrade program, embedded within the client’s existing team in Sydney.
The Delivery Manager owns each client migration from kickoff through environment cloning, platform upgrade, validation & certification, and production cutover — ensuring every client moves through each stage in a controlled, certified and predictable way, while acting as the primary point of contact for the client throughout.
The role sits at the intersection of technical delivery, quality control and client relationship management. Strong client-facing communication, technical fluency, and the ability to manage delivery under pressure are essential.

Execution must ensure that all entry and exit criteria are met at each stage before a client is progressed to the next one. Delivery Managers operate effectively across multiple concurrent implementations or client accounts, managing competing priorities without compromising quality.
2. Certification & Quality Control
Ensure validation and certification are completed prior to cutover — no client proceeds to production on an uncertified environment.
Coordinate with QA and Engineering to confirm:
Functional parity between the existing and upgraded platform
Data integrity across the migrated environment
Unchanged system behaviour from the client’s perspective
Certification evidence is captured and traceable for each client
3. Wave & Batch Execution
Allocate and manage clients across migration waves based on:
Complexity of the client environment and configuration
Transaction volume (TPS)
Integration footprint and client-specific dependencies
Business criticality and acceptable change windows
Ensure execution aligns with:
QA certification capacity
Controlled batch progression — each batch is only released once the preceding batch is stable
4. Cutover Execution
Plan and coordinate production cutovers, including scheduling, readiness checks, communication and rollback planning, ensuring smooth transition and post-launch system stability
Ensure that:
Backend system transition occurs smoothly with minimal client impact
Post-cutover validation is completed and signed off
System stability is confirmed before the client is declared complete
Any issues arising during or after cutover are triaged and resolved without delaying the wider program
5. Client Coordination
Delivery Managers are responsible for managing client-specific configuration and integration considerations that may affect go-live readiness, including:
URL Masking
IP Whitelisting
Webhooks
API Usage Patterns
System access and data migration / connectivity to third-party integrations
These activities:
May not block migration execution, but can impact client usage if left unmanaged
Require proactive coordination and clear communication with client technical and business contacts
Must be actively managed to ensure post-cutover stability and client confidence
6. Client Relationship & Communication
Act as the primary point of contact for the client throughout the implementation lifecycle, managing expectations and communicating status transparently — including when things are behind plan
Build trust with client stakeholders through direct, solutions-oriented communication — able to explain technical issues in business terms and vice versa
Manage scope changes and client requests, balancing client expectations against delivery commitments and contractual scope
7. Risk & Issue Management
Identify, escalate and mitigate delivery risks and issues, including:
Certification gaps
Data inconsistencies
Cutover execution issues
Client configuration or connectivity gaps
Be the direct point of contact for client escalations. Escalate early and transparently, and maintain delivery momentum without compromising quality.
Proven Delivery Manager experience in enterprise SaaS or platform environments, including migration or upgrade programs
Strong experience in client-facing delivery and production cutovers — a track record of running live implementations, onboarding, or system cutovers where continuity for the end customer was critical
Ability to manage multiple clients concurrently across structured waves and batches, under defined entry and exit criteria
Strong stakeholder management and risk/issue management skills, with the ability to work independently in a fast-paced, execution-focused environment
Excellent English communication skills, both written and verbal
Sydney-based, available to work on-site/hybrid as required by the client
Technical Requirements
Sufficient technical fluency to engage credibly with engineering teams and assess whether a technical issue is genuinely difficult or simply being deprioritized
Working understanding of data migration, system integrations, connectivity, and third-party APIs in an enterprise context
Prefer
Experience in identity, fintech, banking/payments, or other regulated/enterprise SaaS environments
Experience with high-volume / high-TPS platforms
Experience in AWS-based environments
Hands-on technical background (development, systems, or infrastructure) — no longer needs to be actively coding
