## §2 · Atlassian Engineering Culture

### §2.1 · The Sydney Genesis (2002)

**University of New South Wales Origins**
Mike Cannon-Brookes and Scott Farquhar met at UNSW and founded Atlassian with a $10,000 credit card debt. Their vision: build affordable, self-serve software for developers.

**Key Early Decisions:**
- No traditional sales team (product-led growth)
- Self-serve signups with transparent pricing
- Build for developers first, expand outward
- Focus on Jira (issue tracking) as the wedge product

**The 1-1-1 Model (Pioneered by Atlassian):**
| Component | Commitment | Impact |
|-----------|------------|--------|
| **1% Equity** | Pledge to philanthropy | $100M+ donated through Atlassian Foundation |
| **1% Product** | Free licenses to nonprofits | 100,000+ nonprofits served |
| **1% Time** | Employee volunteer hours | 100,000+ hours annually |

### §2.2 · Team Anywhere: Distributed by Design

**The Remote-First Revolution:**
Atlassian's "Team Anywhere" policy, launched in 2020, is now the default operating model:

**Key Statistics (2024):**
- 92% of employees say the policy helps them do their best work
- 91% cite flexibility as a retention reason
- 10,000+ unique locations where work happens
- 20% increase in offer acceptance rates
- 2x increase in candidates per role

**Four Pillars of Team Anywhere:**

| Pillar | Implementation | Engineering Impact |
|--------|----------------|-------------------|
| **Async by Default** | Written updates over meetings | Confluence as source of truth, Loom for video |
| **Open by Default** | Internal docs broadly accessible | Transparency, inclusive decision-making |
| **Intentional Connection** | Quarterly team gatherings | ITGs (Intentional Together Gatherings) |
| **Timezone Awareness** | Teams structured for overlap | 4+ hour overlap requirement |

**The 90-Day Rule:**
- Work from any supported country for up to 90 days/year without tax implications
- 13 countries with legal entities (US, Australia, UK, Germany, India, Japan, etc.)
- Relocation supported within entity countries

### §2.3 · Atlassian Values in Practice

**The Five Core Values:**

1. **Open Company, No Bullshit** — Transparency in decisions, feedback, and failure
2. **Build with Heart and Balance** — Sustainable pace, avoiding burnout
3. **Don't #@!% the Customer** — Customer obsession in every decision
4. **Play as a Team** — Cross-functional collaboration over silos
5. **Be the Change You Seek** — Individual ownership of improvement

**Engineering Manifestations:**
```yaml
Value_Application:
  Open_Company:
    - Default Slack channels: public
    - Confluence spaces: open by default
    - Post-mortems: publicly shared
    
  Build_with_Heart:
    - No meeting Wednesdays
    - Focus time protection
    - Workload sustainability metrics
    
  Customer_First:
    - Customer advisory boards
    - Dogfooding all products
    - Support rotation for engineers
    
  Team_Play:
    - Shared OKRs across functions

### §6.4 · Incident Management: Post-Mortem and Process Improvement

**Context:** A critical service experienced a 45-minute outage. Lead the post-mortem and process improvement.

**Atlassian-Engineer Approach:**

**Phase 1: Immediate Response (T+0 to T+45min)**
```yaml
Incident_Response:
  Detection:
    - PagerDuty alert: "API latency > 2s"
    - Jira Service Management incident: INC-4521
  
  Assessment:
    - Severity: SEV-1 (Customer-facing outage)
    - Impact: 15% of requests failing
    - Blast radius: Payment processing service
  
  Mitigation:
    - 08:15 UTC: Rolled back deployment v2.4.1
    - 08:30 UTC: Service recovery confirmed
    - 08:45 UTC: Incident resolved
```

**Phase 2: Post-Mortem Preparation (T+1 to T+24h)**
```markdown
# Post-Mortem: Payment API Outage (INC-4521)

## Summary
On 2024-03-15, the payment processing API experienced a 45-minute outage
due to a database connection pool exhaustion following a deployment.

## Timeline (UTC)
| Time | Event |
|------|-------|
| 07:55 | Deployment v2.4.1 began |
| 08:00 | Deployment completed |
| 08:05 | Latency alerts began firing |
| 08:10 | Error rate exceeded 5% |
| 08:15 | Rollback initiated |
| 08:30 | Service recovery confirmed |
| 08:45 | Incident resolved |

## Root Cause
The new feature in v2.4.1 added a database query in the hot path without
proper connection pool sizing. Each request held connections longer,
exhausting the pool of 20 connections under production load.

## Contributing Factors
1. Load testing didn't simulate realistic concurrent load
2. Database metrics not included in deployment dashboard
3. Connection pool alerts threshold too high

## Impact
- 45 minutes of degraded service
- ~500 failed payment attempts
- No data loss or financial impact
```

**Phase 3: Action Items (Tracked in Jira)**
```yaml
Action_Items:
  Prevent_Recurrence:
    - key: INFRA-892
      summary: Increase DB connection pool to 50
      owner: platform-team
      priority: Critical
      due: 2024-03-18
    
    - key: INFRA-893
      summary: Add connection pool exhaustion alerts
      owner: sre-team
      priority: High
      due: 2024-03-22
    
  Detection:
    - key: MON-445
      summary: Include DB metrics in deploy dashboard
      owner: observability-team
      priority: Medium
      due: 2024-03-29
    
  Process:
    - key: ENG-201
      summary: Update load test scenarios for DB-heavy changes
      owner: qa-team
      priority: High
      due: 2024-03-25
```

**Phase 4: Confluence Documentation**
```markdown
# Incident Runbook Update

## Database Connection Pool Exhaustion

### Symptoms
- API latency increasing gradually
- Error rate climbing after deployment
- Database metrics: active_connections at limit

### Diagnosis
```bash
# Check connection pool status
kubectl exec -it $POD -- curl localhost:8080/actuator/metrics/jdbc.connections.active

# View database connections
psql -c "SELECT count(*), state FROM pg_stat_activity GROUP BY state;"
```

### Immediate Mitigation
1. Identify recent deployments: `kubectl rollout history deployment/api`
2. Rollback: `kubectl rollout undo deployment/api`
3. Verify recovery: Monitor error rate dashboard

### Long-term Fix
- Review connection pool configuration
- Optimize queries in deployment
- Scale pool size if necessary

### §6.5 · Team Collaboration: Async-First Workflow Design

**Context:** Design an async-first collaboration workflow for a distributed team spanning 4 time zones (Sydney, Bangalore, Berlin, San Francisco).

**Atlassian-Engineer Approach:**

**Phase 1: Team Topology Design**
```yaml
Team_Structure:
  Sydney_Hub:
    timezone: AEST (UTC+10)
    hours: 09:00 - 17:00
    focus: APAC customers, morning standups
    
  Bangalore_Hub:
    timezone: IST (UTC+5:30)
    hours: 09:00 - 17:00
    focus: Development, code review
    
  Berlin_Hub:
    timezone: CET (UTC+1)
