Job summary

Decipher Bureau in Australia is seeking a Python Software Engineer to build production-grade, AI-powered security tooling. You will own the full lifecycle from design to deployment, shaping what to build and how it works.

You will work with a world-class engineering team to integrate AI into security products and automate analyst workflows. The role emphasizes building agentic AI systems, data pipelines, and secure, scalable services, with autonomy and a keen eye for security best practices.

Qualifications

• Strong backend engineering with Python (Flask/FastAPI) and production-grade systems.
• Experience integrating LLMs into applications or products.
• Hands-on experience with agentic AI patterns and tooling.
• Knowledge of AI best practices, strengths and weaknesses.
• Curious mindset with drive to push boundaries.
• Track record owning systems end-to-end from design to production support.

Responsibilities

• Design, build and operate applications and backend services for internal security tooling.
• Integrate LLMs directly into production products.

Job description

Are you a Python Software Engineer who wants to move beyond experimenting with AI and start building production-grade, AI-powered security systems?

We're hiring for an Australian Financial Services organisation building the next generation of internal cyber tooling.

Build the agents, tools and systems that make security teams faster, more efficient and more effective. You'll have genuine ownership across the full lifecycle, from shaping what should be built and how it works, through to implementation and deployment.

Think of an AI agent taking a security alert, pulling together the relevant data, cross-referencing threat intelligence and producing a first-pass assessment - so the analyst can focus on making the decision, rather than finding the information.

Innovative solutions to security, driven by you and a world class engineering team.

What You'll Do

• Design, build and operate applications and backend services for internal security tooling
• Integrate LLMs directly into production products
• Build agentic AI systems to make Cyber Security teams more effective.
• Build and maintain data pipelines that ingest and process security data, including logs, scan results and alerts, for both human and AI consumption
• Own solutions end-to-end: design, build, test, deploy and support in production
• Collaborate closely with security engineers and analysts to understand real workflows and pain points
• Participate in code reviews, architecture discussions and agile ceremonies within a DevOps-driven team

Must-have

• Strong backend engineering experience with Python, using Flask, FastAPI or equivalent
• Real, production experience integrating LLMs into applications or products
• Hands-on experience with agentic AI patterns and tooling
• You know what AI good practices look like, the strengths and weaknesses
• Your curious, want to push boundaries
• A track record of owning systems end-to-end, from design through to production support

Nice-to-have

• Familiarity with cyber security concepts, including vulnerabilities, threat data, SOC workflows and security tooling.
• Cyber can be upskilled. What's important here is the Software and AI expertise.

Why This Role?

• Work on high-stakes, real-world problems where your tools directly improve how a security team operates
• Join a team that's serious about doing agentic AI properly
• Full ownership and autonomy over what you build
• Healthy package, benefits + bonus

Please note: Full Australian working rights are required for this position.
