Application Security Engineer With Developer Background
Join our mission towards a safe digital future
Do you want to be at the forefront of protecting our society against cyber threats? We are looking for an Application Security Engineer to team up with the most dedicated team of cyber specialists in our Secure Development domain.
About Truesec – A Leading Cybersecurity Company
Since 2005, Truesec has been a native cybersecurity company, driven by one single purpose: Creating safety and sustainability in a digital world by preventing cyber breach and minimizing impact.
Over the years, we’ve earned the trust of organizations worldwide and gained a strong reputation internationally. Our team consists of dedicated specialists covering the entire spectrum of cybersecurity – with capabilities in Predict, Prevent, Protect, Respond, and Recover.
Today, we employ around 200 employees – and as cybercrime grows, we need to grow. To support that goal, we are now looking for an Application Security Expert who wants to create advanced security solutions in our Secure Development domain.
Secure Development
Applications and custom solutions are currently popular targets for threat actors. In
modern application development, security must be present throughout all aspects of the development process. Our engagements span from AppSec-related security
workshops, educating organizations in secure coding and DevSecOps, to longer
assignments where we write code responsibly as integrated team members. We are a cyber tech company with our own custom software and services that we leverage both during assignments and with our clients.
The Role
Over the course of a year at Truesec you will meet many customers and their
development organizations. Some you might only see for a day, others for longer; the important thing is that you’ll help them develop more secure solutions! That might be by helping customers form secure development processes, or in more targeted assignments, audit their proposed or already developed systems. You may also help them through workshops or education, code reviews, or perhaps with threat modelling exercises. As you can understand, the needs and techniques could differ depending on the project. It is therefore important to us that you feel confident in both your experience and skillset.
We generally work in pairs or teams during our assignments, not only so you feel the safety and support of the organization, but also because we want to create the most value for our customers. Staying up to date is important in our field, and to enable that, we encourage continuous learning during work hours as well as conference visits and knowledge sharing with colleagues.
Your Potential Background
You have a thorough background in writing code and software design, broad
knowledge in application security, and have possibly worked actively within the field during the last five years.
Due to the sensitivity in our assignments, Swedish citizenship, citizenship in an EU country, or a Swedish work permit is a requirement for this position.
In short, we believe your previous experience could include:
• DevSecOps and secure coding practices.
• Software architecture and design.
• Programming skills in one or more languages, preferably within either Java, C#, C/C++, Python, JavaScript, or Go.
If you have experience in any of the following, we will consider it a bonus:
• Cryptography/Authentication/Authorization.
• OAuth 2/OpenID Connect/JWT.
• Distributed systems/Docker/Kubernetes.
• AWS, Azure, or GCP.
• Threat modeling and security assessments of code.
• Penetration testing.
• SAST/DAST tools.
• Vulnerability management.
