Application Security Engineer

Published on April 16, 2024

Pennylane is building the financial OS (Operating System) for European SMEs. A single source of truth for financial data, used on one side by entrepreneurs to run their business (invoicing and getting paid, paying suppliers and expense management, piloting cash and profitability) and on the other side by their accountant for bookkeeping and fiscal declarations.

Saving time to all entrepreneurs and accountants, helping them to make the right decisions and enabling 3rd parties to offer added-value personalized financial services.

We’ve launched in France and will expand to other markets in Continental Europe in 2022. Our commercial website is thus in French only but the code is obviously documented in English and our tech team speaks English.

Are you looking to have an impact on the daily life of millions of entrepreneurs in France and Europe?
Do you thrive in a trustful, fast-paced environment?
Do you feel like our Engineering principles are aligned with your vision ?

Then Pennylane might be the right place for you — and you, might be the perfect fit for this role 🙂

Our vision

We aim to become the most beloved financial Operating System of European SMEs.

We help business owners get rid of the time consuming hassle of handling accounting and finance, while giving them access to key information that they can use to make better decisions.

Meanwhile, we’re helping accountants. By using Pennylane, rather than doing manual and repetitive tasks, they can spend more time advising and guiding their clients.

WHY this position is of utmost importance to reach our mission

We are looking for an Application Security Engineer to join Louis and Romain in the technical security team. Reporting directly to Guillaume, our Head of Information Security, you will be responsible for all technical matters involving security issues. Working with the security compliance team, you may be required to provide technical support to the team in the definition and monitoring of long-term projects designed to strengthen the security of our assets in a sustainable manner. You will have a key role in advising, assisting, informing, training and alerting all employees (especially developers). You will also be responsible for the day-to-day management of technical operations in the context of ISO 27001 certification.

The technical security team is involved from the identification/detection of a security issue to its resolution (development and implementation of the security patches). If the needs or the complexity of the patch are too great, the security team can count on the support of the developers and in particular the Security Champions team to sustain the effort.

🎯 Your tasks

You will be required to work on :

- All technical security issues/projects while providing technical support on compliance needs

Let’s break it down ⏬

- Security by design within the projects by discussing with the teams to consider the security risks
- To be proactive in the security projects to be carried out, to define and to prioritize them
- Ensure the security of the main Web application in Ruby on Rails and React: its dependencies, its code, its infrastructure and its configuration
- Security and maintaining the security condition of other applications and AWS infrastructure, including its Kubernetes environment (AWS EKS)
- Conduct and perform regular security assessments (internally or by an external firm) on the applications (code reviews/pentests/bug bounty in particular) and the infrastructure 
- Ensure compliance with ISO 27001 controls (processes) related to development (mandatory code practices, validation, patch management, vulnerability management, etc.) by training developers, monitoring projects (tech, product), conducting regular internal audits and managing tech non-conformities
- Conducting code reviews from a secure development point of view (about 80 releases per day, not all of which have security implications, but it is an important and recurring topic)
- Build/Improve secure development training materials and conduct regular training sessions with the developers
- Contribute to tenders to explain our security policies and provide the necessary technical details
Learn about Rails and React to detect vulnerabilities during code reviews and implement associated patches
- Strengthen the current means of detecting malicious attempts

These missions are not exhaustive and remain evolving.

🥇You’re the right candidate if

- You are mid/senior level in defensive or offensive application security, are a quick learner and like to work on different projects. As a security team member at Pennylane, you’ll work on all security topics (application, cloud infrastructure, security by design, training, ISO 27001, etc.).
- Working in an English-speaking environment doesn't scare you, you don't need to be bilingual. You need to be able to share your ideas and thoughts well in spoken and written English and to understand what is being said. If you need help with this, we can provide you with a Busuu subscription to improve your English immediately.
- You ideally have the following skills/experience ⏬
- Able to perform offensive security assessments on an infrastructure or an application
- You know how to exploit and fix a wide range of Web vulnerabilities (not just the OWASP top 10)
- You already have an experience in a programming language (Ruby, Python, JavaScript), either for quick and dirty scripting to exploit a vulnerability or for larger projects
- You have an experience in cloud infrastructure security
- You are able to popularize technical terms to facilitate the adoption of security measures within projects or to broadcast messages to Pennylaners
- You are autonomous, proactive and organized
- Working with remote colleagues is not an issue for you

Bonus: if you have already developed in Ruby or React and/or if you have technical application security certifications. A multi-skilled profile will be preferred.

We're working on providing those last advantages to our people based outside of France as well, but it can be quite more complex depending on different countries.
