About Flo Energy
Hi, we are Flo! We are on a mission to switch as many people and businesses as possible to affordable, renewable solutions.
We began in a small shophouse in Singapore and have grown rapidly ever since, expanding into Australia with even bigger plans ahead.
Unlike other retailers, we have built our own best-in-class energy platform entirely in-house. Designed specifically for the sector, it automates complex processes and keeps costs down, letting us offer genuinely affordable products to our customers.
Behind Flo is a diverse team of passionate engineers, data scientists, operators, and energy experts. We come from different backgrounds, but we are united by the shared goal of creating a more sustainable future. If you want to make an impact and help accelerate the renewable energy transition, we would love to meet you.

About the role
We are seeking a Senior Security Engineer (DevSecOps / Application Security) to join Flo as our first dedicated security engineer, focusing on embedding security into our application development and cloud infrastructure.
You will work closely with Engineering and Platform (DevOps) teams to integrate security into the software development lifecycle and cloud environments. This role is hands-on and execution-focused, while also requiring the ability to identify security gaps, recommend improvements, and influence teams to adopt secure practices.
This role is ideal for someone who enjoys working closely with developers, improving security in real-world systems, and driving practical security outcomes through collaboration.
What you'll do
As the Senior Security Engineer, you will focus on application and cloud security while supporting the broader cybersecurity posture of the organization. As the first security engineer, you will play a key role in improving how security is implemented in practice and how engineering teams adopt secure development practices.

- Collaborate with developers to embed secure coding practices and conduct code reviews for high-risk features.
- Conduct threat modeling and provide security input on application and cloud design.
- Integrate security scanning tools (SAST, DAST, SCA) into CI/CD pipelines.
- Collaborate with the Platform Team (DevOps) to secure containerized workloads (e.g., Docker, Kubernetes), infrastructure-as-code, and serverless applications.
- Work with the Platform Team to secure configuration across AWS accounts, including IAM, encryption, and network controls.
- Implement and manage Web Application Firewalls (WAFs) to protect applications from OWASP Top 10 vulnerabilities and other common attacks.
Security Innovation & Continuous Improvement:
- Stay current with emerging threats, vulnerabilities, and cybersecurity technologies.
- Proactively identify security gaps and drive practical improvements across application and cloud environments.
