The EH Way

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

• 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
• We are Remote First – we champion a remote environment with a preference for asynchronous communication and a high degree of autonomy
• 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
• We are Apolitical – we do not take a position on political or social topics, unless it relates to our Mission
• We Live by Our Values – we role model our values 100% of the time
• We Expect High Performance – we set a high standard and we're not satisfied with being average

This role

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.

Who you are

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.
• Experience shipping and operating scalable web services.
• AI-first mindset – fluent with ChatGPT, or similar tools to accelerate ideation, coding and analysis.
• Strong understanding of modern engineering practices including automated testing, CI/CD, trunk-based development and agile squad models.
• Analytical thinker who can turn messy fraud data into actionable insights.
• Clear and persuasive communicator able to translate technical findings into risk, customer impact and business value.
• Bonus Points If You Have
• Exposure to fraud detection, abuse prevention, threat hunting or product security.
• Experience with growth-stage SaaS or high-traffic marketplace products.
• Familiarity with Datadog, SIEM, KYC/KYB or WAF tuning.

What is in it for you

• Meaningful scope owning fraud and abuse defences that protect millions of end-users.
• Speed and autonomy to ship ideas quickly in a supportive, low-bureaucracy culture.
• AI playground with budget and freedom to experiment with cutting-edge generative AI tooling.
• Competitive package including base salary and stock options, with a premium band for exceptional candidates.
