🔐 About Global Cybersecurity & CSAT

Global Cybersecurity enables businesses and functions to manage information, technology, and cybersecurity risks through clearly defined, assessed, and implemented controls. The team operates as part of the first line of defence within the risk management framework.

The Cybersecurity Assessment and Testing (CSAT) function is responsible for:

• Vulnerability Management

• Secure Development (including DevSecOps)

• Threat and Controls Assessment (including threat modelling)

• Third-Party Security Assessment

CSAT drives the identification, assessment, testing, and remediation of security vulnerabilities across on-premise, cloud, and third-party environments.

🛠️ What You Will Be Doing

Reporting to a CSAT Development Lead and working in an agile / DevSecOps environment, you will take part in a wide range of engineering activities, including:

• Designing, developing, and deploying REST API services for internal users

• Building integrations with third-party security tools

• Developing data pipelines and ETL processes

• Creating and maintaining CI/CD pipelines

• Supporting existing services (L2/L3 troubleshooting, bug fixing)

• Writing automated test scripts and technical documentation

• Conducting peer code reviews and mentoring junior engineers

Our primary programming language is Python, and we follow microservice architecture principles to ensure scalability and loose coupling.

You will work closely with cybersecurity subject-matter experts to deliver solutions that automate vulnerability detection, integrate scanning tools, and develop in-house security assessment capabilities.

✅ Key Responsibilities

• Collaborate with Product Owners and Development Leads to deliver high-quality software solutions

• Translate cybersecurity requirements into scalable technical solutions

• Adhere to established design, development, and governance standards

• Continuously improve development efficiency through automation

• Ensure reliability and operability of existing services

• Lead by example through best practices and peer reviews

🎯 What You Will Bring

Must Have

• Extensive Python web development experience (FastAPI preferred; Flask or Django accepted)

• Experience building data pipelines using Python (Pandas, NumPy, Airflow, Luigi, etc.)

• Strong understanding of microservice architectures (CQRS, SAGA, event sourcing)

• Hands-on experience with Docker and Kubernetes

• CI/CD experience using tools such as Jenkins or GitLab

• Strong Linux system administration skills and networking knowledge (TCP/IP, DNS, firewalls, subnetting)

• Proficiency with Git and branching strategies (GitFlow, trunk-based, etc.)

• Front-end development experience (HTML, CSS, JavaScript)

• Strong SQL skills, including complex query design

• Test-driven mindset with experience in automated testing

• Solid understanding of Agile and DevSecOps in regulated environments

• Excellent written and verbal communication skills

• Proven ability to work effectively in fast-paced, team-oriented environments

• A strong desire to learn and share knowledge

Great to Have

• Cybersecurity experience (SAST, DAST, penetration testing, fuzzing, threat exploitation)

• Cloud experience (AWS, GCP, Azure, AliCloud) and Infrastructure as Code (Terraform)

• Monitoring and service mesh tools (e.g. Prometheus, Anthos)

• Strong front-end skills, ideally with React

• Experience with analytics tools (e.g. Matomo) and UX/design principles

• Database architecture and administration experience (PostgreSQL, MSSQL, MongoDB)

• Experience with message queue systems (Kafka, RabbitMQ)

A successful candidate will meet all “must have” requirements and at least one “great to have”.
