Lead Underwriter

As a Lead Underwriter in our intermediated Personal Lines portfolio, you’ll play a key role in managing complex underwriting decisions, broker escalations and portfolio risk — while supporting and mentoring a highly experienced underwriting team. You’ll lead through your expertise, influencing decisions that sit beyond standard underwriting and helping maintain consistency and quality across the portfolio. 

You’ll join a fast‑paced, high‑volume environment where commercial judgement, clarity and confidence are essential. This is a role for an experienced underwriter who is comfortable navigating complexity, balancing risk with opportunity, and communicating decisions with impact.

This is a permanent full-time role based in Naarm (Melbourne) or Tarndanya (Adelaide). 

What You'll Do 

• Underwrite and review complex risks, including escalations, adverse claims histories and non‑standard exposures, within risk appetite and delegated authority. 

• Act as a senior technical referral point, providing clear, well‑reasoned underwriting decisions to brokers and internal stakeholders. 

• Manage broker escalations and negotiations, balancing portfolio performance with long‑term broker relationships. 

• Support and mentor underwriters through technical guidance, case discussions and constructive feedback. 

• Maintain strong governance by applying underwriting standards, guidelines and compliance requirements consistently. 

• Contribute to portfolio performance by identifying risk trends and supporting continuous improvement in underwriting quality. 

What You'll Bring 

• Significant experience in complex underwriting, ideally within Personal Lines underwriting or a similar intermediated environment. 

• Demonstrated experience operating at a senior or lead underwriter level, with confidence making complex decisions. 

• Strong understanding of underwriting appetite, authority, escalation management and applied risk judgement. 

• Confident communicator, able to clearly explain underwriting decisions to brokers and internal stakeholders. 

• Experience supporting or mentoring others through technical expertise and guidance. 

• Ability to perform in a high‑volume, fast‑paced environment, managing competing priorities effectively. 

What We Offer 

• Boosted superannuation with 13% as standard. 

• 20 days annual leave + 5 days MyLeave (extra leave for what’s important to you). 

• Work from home and many more flexibility options with myFlex. 

• Up to 50% off personal insurance, including home and motor insurance. 

• Partner discounts on private health insurance, tech & appliances, and many more. 

• Industry-leading 20 weeks paid parental leave.
