How do we work?

We are looking for a Senior Application Security Engineer to join our global Team and help us "push security left" across our entire product ecosystem. At OANDA, we believe security is everyone's responsibility, so we focus on developer education, continuous automation and building defense-in-depth rather than just checking compliance boxes.

You will work directly with cross-functional engineering teams in hands-on coding engagements to demonstrate secure design principles in action. Operating across a modern, multi-language stack and cloud environments, you’ll tackle security challenges at every layer. From automating DevSecOps pipelines to pioneering AI security tooling, we foster a high-energy environment focused on continuous growth and partnership.

In this role, you will:

Lead & Advocate: Provide technical leadership in application security, conduct threat modeling, lead design reviews, and establish secure coding practices.

Build & Remediate: Directly build security-critical components and fix vulnerabilities across multiple languages (JS, Go, Python, C++, Java).

Apply Defense-in-Depth: Touch every layer of our stack — from system hardening and Terraform (IaC) cloud security to reviewing C++ code and applying modern cryptography/secrets management (PKI, hashing).

Automate DevSecOps: Implement static code analysis, fuzzing, composition analysis, to make security proactive and effortless for developers.

Threat Modelling: Develop and lead on Threat Modelling exercises to identify risk, threats and vulnerabilities in the development phase of our applications

Pioneer AI Security: Identify and implement best practices for secure AI development and AI security tooling.

Secure Supply Chains: Work with dev teams to identify, track, and remediate third-party library vulnerabilities and supply-chain risks.

What skillset you need, to be successful in this role:

2 - 5 years of relevant technical experience, with 1-2+ years focused specifically on application security / security engineering.

Expert-level knowledge of web application vulnerabilities (OWASP Top 10), attack vectors and secure code review.

Strong ability to develop in and navigate security pitfalls in at least one primary programming language (e.g., Python, Go, Java, C#, or JavaScript/C++).

Hands-on experience with modern testing tools (SAST, DAST, IAST, SCA, penetration testing frameworks).

Working knowledge of cloud platforms (AWS, Azure, or GCP), networking, databases, and containerized/IaC environments.

Ability to simplify complex security challenges and drive proactive solutions with urgency, high energy, and teamwork.

Nice to have:

Experience in Fintech / Financial Services (or familiarity with financial security threat models & regulations).

Hands-on experience writing Terraform (Infrastructure as Code) and managing cloud secrets.

Exposure to AI development frameworks, AI tooling security, or LLM vulnerability vectors.

Knowledge of industry compliance standards & privacy regulations (SOC2, ISO27001, NIST, GDPR).

Active involvement in the wider cybersecurity community (conferences, open-source security projects).
