Engineering Team Lead

The Engineering Lead / Architect is responsible for defining and governing the end‑to‑end solution architecture for the migration of Atlassian Jira and Confluence from Data Center (DC) to Atlassian Cloud
. This includes designing the near real-time data replica
, abstraction API
, integration patterns
, and the technical migration blueprint
.

The role acts as the technical lead across all phases of the migration lifecycle —
Discovery, Cleansing, Standardisation, Target-State Design, Pilot Migration, UAT, Production Cutover, Validation, Reconciliation, Hypercare, and BAU Handover
. The Architect ensures the entire solution is robust, scalable, secure, and aligned with enterprise architecture standards
.

• Design the end-to-end architecture covering data replica
  , synchronisation engine
  , abstraction API
  , and overall integration landscape
  .
• Define canonical data models
  , API contracts
  , transformation rules
  , and mode-switch logic for dual-running DC and Cloud systems.
• Evaluate and select suitable technology platforms for database, integration, API gateway, message/event streaming, and automation.

• Ensure adherence to security, compliance, data privacy, legal hold, and regulatory requirements throughout the migration.
• Establish data governance standards, lineage, traceability, and audit requirements for Jira/Confluence migration.

• Produce architectural artefacts including HLDs, LLDs, sequence diagrams, data flow diagrams, design specifications, and decision logs (ADRs).
• Review, validate, and approve detailed technical designs delivered by engineering teams and vendors.
• Provide expert guidance on scalability, resiliency, performance optimisation, rate limiting, and error-handling patterns
  .

• Lead the team across all migration phases:
• Pre-Migration: Discovery, data cleansing, configuration standardisation, integration analysis, target-state architecture.
• Migration Execution: Pilot migration, iterative migration waves, UAT cycles, production cutover.
• Post-Migration: Validation & reconciliation, defect resolution, hypercare, and operational handover.
• Support the Program Manager in technical risk management, issue resolution, dependency tracking, and executive-level reporting.
• Collaborate with cross-functional teams including architecture, engineering, security, product owners, and Atlassian partners.

• 8+ years in Solution Architecture or Enterprise Architecture
  , ideally within large-scale transformation programs.
• Deep hands‑on knowledge of:
• Hybrid cloud/on‑prem architectures
• Familiarity with Atlassian Cloud APIs
  , REST endpoints, export/import frameworks, identity integrations, and associated tooling.
• Strong experience producing architecture documentation, design specifications, diagrams
  , and decision logs.
• Excellent communication, stakeholder management, and leadership skills.

• AWS Certified Solutions Architect – Professional
• Azure Solutions Architect Expert
• Google Professional Cloud Architect
