Technical System Design & Architecture
While you may not be writing production code daily, an Engineering Manager at Airwallex Pty must command the respect of senior engineers and guide critical architectural choices. This area evaluates your ability to design scalable, fault-tolerant, and secure distributed systems, which is paramount in the fintech space. Strong performance means you can confidently sketch out high-level architectures, identify bottlenecks, and make pragmatic trade-offs regarding data consistency, latency, and throughput.
Be ready to go over:
- Microservices Architecture – Designing decoupled services, API gateways, and service meshes.
- Data Storage and Consistency – Choosing between SQL and NoSQL, understanding ACID properties, and managing distributed transactions (e.g., Saga pattern).
- High Availability and Resilience – Implementing rate limiting, circuit breakers, and failover strategies.
- Advanced concepts (less common) – Event sourcing, CQRS (Command Query Responsibility Segregation), and idempotency in payment processing.
Example questions or scenarios:
- "Design a high-throughput, low-latency payment routing system."
- "How would you architect a distributed ledger that guarantees eventual consistency across multiple global regions?"
- "Walk me through a time you had to resolve a critical architectural disagreement within your team."
People Leadership & Team Building
Your primary responsibility is to your team. This area tests your emotional intelligence, coaching skills, and organizational design abilities. Interviewers want to see that you can attract top talent, manage underperformers gracefully, and create an environment where engineers thrive. A strong candidate provides nuanced, empathetic answers that focus on individual growth and team cohesion.
Be ready to go over:
- Hiring and Scaling – Strategies for sourcing, interviewing, and onboarding engineers in a competitive market.
- Performance Management – Conducting effective 1-on-1s, setting OKRs, and guiding engineers through promotion cycles.
- Conflict Resolution – Navigating interpersonal issues or disagreements over technical direction.
Example questions or scenarios:
- "Tell me about a time you had to manage out an underperforming engineer."
- "How do you balance the need for rapid feature delivery with an engineer's desire to work on technical debt or learn a new technology?"
- "Describe your framework for running effective 1-on-1s."
Cross-Functional & Global Stakeholder Management
At Airwallex Pty, engineering is deeply intertwined with product, operations, and sales. Because our products serve global markets, you will frequently interact with stakeholders across different continents and disciplines. This area evaluates your communication skills, business acumen, and ability to push back constructively. Strong candidates show they can align engineering goals with overarching business metrics.
Be ready to go over:
- Roadmap Negotiation – Balancing product requests with engineering capacity and technical debt.
- Cross-Border Communication – Managing expectations and collaborating with teams in different time zones (e.g., aligning London engineering with US sales).
- Incident Communication – How you communicate technical outages or delays to non-technical stakeholders.
Example questions or scenarios:
- "Tell me about a time you had to say 'no' to a demanding stakeholder from the Sales or Product team."
- "How do you ensure your engineering team understands the commercial impact of what they are building?"
- "Describe a scenario where you had to align priorities between two teams located in different global regions."
Delivery & Agile Execution
This area focuses on the mechanics of how your team gets work done. Interviewers will assess your operational rigor and how you optimize the software development lifecycle (SDLC). A strong candidate demonstrates a data-driven approach to engineering management, using metrics to identify bottlenecks and improve velocity without sacrificing quality.
Be ready to go over:
- Agile Methodologies – Adapting Scrum or Kanban to fit the team's specific needs.
- Engineering Metrics – Tracking DORA metrics (deployment frequency, lead time, MTTR, change failure rate).
- Quality Assurance – Integrating testing, CI/CD, and security reviews into the delivery pipeline.
Example questions or scenarios:
- "What metrics do you use to measure the health and productivity of your engineering team?"
- "Walk me through a project that was falling behind schedule. How did you intervene to get it back on track?"
- "How do you ensure security and compliance are built into the development process rather than treated as an afterthought?"
