Application Security Engineer (вакансія неактивна)

Cossack Labs is looking for an Application security engineer to join our Security team and work with us on building and breaking software.

If you are interested in designing and building security controls, working hand-in-hand with software developers, performing security assessments, this may be the position for you!

You will:

• Perform security assessment and review of code and behavior of systems (web, API, backends). Perform risk analysis and threat modelling.
• Perform security research (find security weaknesses and vulnerabilities in software) in novel fields and areas.
• Participate in SSDLC for our products and our customers’ products. Explain risks & threats, work together with developers to select security controls that would improve security without restricting usability/performance.
• Take part in organisation security practices and work with business owners (risk assessment, craft policies for organisations, guide companies for more secure future).
• Stay up to date with emerging security threats, vulnerabilities, and controls (read articles and papers, follow CVE updates, understand how threat landscape is changing, understand how to apply described ideas, read NIST guidelines).
• Dive into application security, infrastructure security, cloud and on-prem infrastructures, dedicated hardware, IoT security, ML security, and weird stuff beyond casual imagination with our team of skilled engineers. See related case study, written from an engineer’s point of view.
• Share your work as conference talks, blogposts (see React Native security example), contribute to open source standards like OWASP.

We would expect you to have:

• Experience in performing security assessment for web (or mobile) apps.
• Experience designing and implementing security processes and security controls in a technically diverse environment.
• Be familiar with application security verification and software maturity frameworks: OWASP SAMM, OWASP ASVS, OWASP MASVS.
• Understanding SSDLC and its difficulties. OWASP SSDLC, NIST SSDF.
• Communication skills: you will communicate about security technical topics with both technical and non-technical audiences (C-level managers, developers, product owners).
• An overall understanding of what information security is, how real-world risks and threats affect the choice of security controls. How to combine detective, preventive and corrective controls.
• Experience in popular security tools required for the job, or ability to learn them quickly (Burp Suite, network analysers, various SAST and DAST, dependency and vulnerability scanners).

As a plus you’d have

• A certain area of expertise and deep interest: web, mobile, IoT, infrastructure — an area where you have “seen things” and ready to share experience.
• Basic knowledge in cryptography: understanding the differences between symmetric and asymmetric cryptography, hashing, KDF.
• Knowledge in one of several business domains: banking / finance / payment processing, cryptocurrencies.
• Understanding security standards and methodologies (NIST, ISO, CMMI, SOC).
• Understanding risk management and threat modelling (NIST RMF, FAIR, STRIDE, MITRE ATT&CK).
• Security engineering or management certifications (CISSP/CISA/CISM or OSCP/CompTIA Security+ or similar).
• Practical experience in scripting languages: Python or Bash.

We offer:

(1) Unique area of expertise:

• Interesting and challenging work in applied security engineering: from building to breaking.
• Working at the intersection of different areas: designing ML security controls, supporting cryptographic protocols with security controls, protecting hardware, building reverse-resilient mobile apps, securing web apps for million of users, etc.
• Combining technologies: cryptography, software engineering, information security. You won’t be bored :)
• Public track record in the open source part of our products, sharing your work as blogs posts, research papers and conference talks. We work with innovative companies all over the world, move quickly and dive into technologies others just hear about.
• A sense of meaning and responsibility for those who seek purpose — we’re building "invisible texture of modern civilization"—bits of infrastructure finance, power grids, healthcare rely on, and we are trusted with very challenging aspects of it.

(2) Environment:

• Friendly and experienced team: smart people to learn from, great people to build with. Each of us is unique, we value and support each other.
• An atmosphere that motivates you to grow and get smarter every month, a healthy ratio of routine / experimentation.
• Trust: schedule, reporting, bureaucracy is kept at reasonable minimum. We hire smart people and trust them to do the right thing. When things go wrong, we help rather than punish.
• Shared decision making: this business is driven by engineering excellence, so engineers are important part of tactical and strategical business decisions.
• Friendly to humans: not just a formal vacation and sick leave quota. Feel like your mental or physical wellbeing needs care? Take some time off. Feel like working a few days from home? Sure. As long as you’re in line, we are here to support you when you’re not.

(3) Growth:

• Team that facilitates internal learning and growth all the time.
• Interesting technologies to work with — sometimes, even unique ones (we design applied cryptography schemes and techniques and novel ways to use them).
• Interesting engineering challenges across the board, ability to hop from high-level system design to protocol reverse engineering and clever data modelling hacks.
• Management attention to help you improve upon your personal goals (through regular 1:1s and mentoring).

(4) Benefits:

• Competitive compensation with flexible bonus scheme.
• Sick leaves, 21 vacation days a year, extra days off — according to agreements and laws.
• Conferences, books, courses — we encourage learning and sharing with the community. Our team members share a lot in talks, workshops and blog posts.

About Cossack Labs:

We are a data security solutions company, developing software products (open-source and proprietary), as well as providing custom bespoke solutions to innovative development teams around the world.

Our software is well-known amongst security-aware teams, recommended by OWASP, and popular for easily solving complicated security challenges. Apart from building “off-the-shelf” solutions, we design custom security controls for novel problems: ML security, end-to-end encryption, secure communication with robotic devices, fintech transactions security, etc.

We work in the B2B space, with customers such as power grid operators, payment processors, legal companies, million-user customer applications. We cater to young ambitious startups and well-established enterprises, who use our software and solutions as core part of their security arsenal. Our customers are smart, but extremely demanding.

Markets: EU, UK, USA.
