Product Security Engineer

Responsibilities

• Being an advocate of security for product owners and engineers, with whom you’ll build a working relationship.
• Performing web, mobile, and backend security assessments directly.
• Orchestrating web, mobile, and backend security assessments between our product teams and third‑party assessors when the situation calls for it.
• Weighing in on technical architecture discussions, ensuring security is considered from the very inception of new features.
• Threat modelling upcoming features, providing a more technical and hands‑on steer when necessary to illustrate security concerns with proposed feature implementations.
• Overseeing secure engineering training programmes, keeping our engineers aware of secure engineering practices, and abreast of the common security pitfalls to avoid.
• Integrating security tooling, stitching together CI steps, scripts, and small tools to automate security controls and visualise their results in a helpful manner. This could include SAST, SCA, DAST, secrets scanning, vulnerability scanning, or other tooling.
• Being guardians of our Secure Development Lifecycle, ensuring security controls are baked in and “pushed left” as much as reasonably possible.
• Triaging incoming reports and findings from bug bounties, automated tools, and more.
• Being comfortable doing “Just‑in‑Time” learning around technologies and frameworks as required to understand emerging technologies in the company, and the security concerns they raise – with appropriate time allocated by the company, of course.
• Advising engineers on security patching, and ensuring our team does as we say by keeping our own tools patched too.
• Staying cognizant of the balance required between security and productivity, and how to manage stakeholder’s concerns around such trade‑offs.

Qualifications

• You have experience in offensive security, such as performing security assessments via tools like BurpSuite, nmap, Kali Linux, etc.
• Strong experience in at least web or a mobile OS, with a willingness to learn the other too.
• Fundamental networking and OS knowledge – you should know how to debug a failing DNS connection, be comfortable with command line tools, and broader computing principles.
• Comfortable threat modelling, assessing the balance between features and security. Being able to explain the trade‑offs to less technical stakeholders.
• Basic scripting knowledge – we have some in‑house tools we maintain ourselves.
• A willingness to learn basic software engineering principles to ensure said tools stay maintainable. Being confident in at least one language such as Python, JavaScript, or Go.
• Secure coding practices – being able to not just spot a SQL injection but provide detailed guidance about how to fix it and prevent it for future queries.
• Providing security advice during architectural design phases of new products. Spotting fundamental security flaws in designs early on, before code is even written.
• Basic cloud infrastructure knowledge, such as understanding the fundamentals of cloud compute instances (VMs), software‑defined networks, and defining infrastructure in code. Having experience in fintech, especially banks with mobile apps.
• Able to read common tech stack languages not commonly used in InfoSec, e.g. Java and C#. This can assist whitebox assessments.
• On top of knowing security skills, knowing fundamental software engineering practices to ensure modifications to our internal tools stay maintainable.
