Software Engineer (Fraud & Abuse)

Employment Hero is on a mission to make employment easier and more valuable for everyone. Our Employment Operating System brings hiring, HR, payroll and benefits into an all-in-one solution. 

Since our inception in 2014, we’ve scaled to a $2 billion valuation and gained a presence in 6 countries globally - Australia, New Zealand, Singapore, Malaysia, the UK and Canada. We now service over 300,000 businesses and more than 2 million employees. 

At Employment Hero, we’re proud of our unique DNA, which we call The EH Way.  

1. We are Mission First - everything we do (from what we work on, to how we allocate capital and where we focus) is driven by our Mission
2. We are Remote First - we champion a remote environment with a preference for asynchronous communication and a high degree of autonomy 
3. We are AI First - we are committed to using AI to accelerate our mission; AI is not just a tool, it’s a fundamental part of how we operate, innovate, and scale
4. We are Apolitical - we do not take a position on political or social topics, unless it relates to our Mission
5. We Live by Our Values - we role model our values 100% of the time
6. We Expect High Performance - we set a high standard and we’re not satisfied with being average

Our HR & Payroll platform processes millions of employee records worldwide. Protecting that data, and the trust it represents, means staying ahead of scammers, fraud rings and malicious automation. We are building a nimble, AI-powered product-security squad to do exactly that.

As our pioneer Software Engineer (Fraud & Abuse), you will combine solid full-stack engineering skills with a curious, adversarial mindset. You will analyse defences, map real-world attack paths in our Jobs, ATS and Talent Marketplace products, and ship counter-measures in days, not quarters. If you enjoy rapid experiments, metrics-driven decisions and the occasional cat-and-mouse game, you will thrive here.

Your key focus areas will be

• Attack-Path Mapping - Re-create real scam workflows end to end to surface choke-points and gaps across our product suite.
• Funnel Integrity Improvements - Propose and implement best-practice patterns to counter free-funnel abuse.
• Experimentation & Metrics - Design test to balance security friction with conversion.
• Rapid Iteration - Monitor emerging attacker tactics, validate detection efficacy and ship counter-measures within days.
• Stakeholder Collaboration - Partner with Marketing (site gating), Product POs, CX Ops and Blue-Team SOC analysts to orchestrate smooth roll-outs.
• Agile Delivery - Blend BA, product-owner and full-stack engineering responsibilities in a single role, owning problems from discovery through to shipped code.
  

To thrive at Employment Hero, you’ll need to embody The EH Way - operating with focus, agility, and an obsession with impact. For this role, you'll have

• 3+ years of professional software development (server-side and RESTful APIs).
• Full-stack proficiency - React (or similar) on the front end, Python, Java, PHP or another OOP language on the back end. You will pick up Ruby with us.
