Security Engineer at Mews – Czechia | Jobyssey

Help make the world more hospitable

The hospitality industry is uniquely human, and it deserves technology that’s just as inspiring as the people behind it. At Mews, we’re transforming the industry with a platform that helps hotels run smarter, move faster and create better guest experiences.

You’ll work with smart, curious people who care deeply about what they do. You’ll have autonomy and the trust to make good decisions and move quickly. And you’ll enjoy a real sense of purpose as you see the impact of what we’re building.

If you’re motivated by ownership, curiosity and meaningful impact, and are driven to deliver consistent high performance, you’ll feel at home here.

About the role

Let's get into the specifics. It’s impossible to capture every nuance of a role – especially at a rapidly growing company like Mews – but if we had to distil it into a job description (which we do because this is a job description), it would be this:

Security is load-bearing infrastructure at Mews. Every payment processed, every guest record stored, every API call made by an integration partner runs through systems this team is responsible for keeping secure. As the Security Engineer joining the Security Engineering team, you will own the tooling and controls that let hundreds of engineers build fast without creating risk they cannot see. This is a building role, not a monitoring role: you will design and implement security capabilities, embed checks into the pipelines (the automated processes that take code from a developer's laptop to production) that engineers use every day, and work directly with product and platform teams to make secure choices the easy ones.

The team is at a high-watermark moment for delivery. A recent promotion to Staff Engineer is great news for Mews, but it has shifted roughly half that person's capacity to a major compliance initiative, leaving a real gap in the security engineering roadmap. Supply chain security, cloud policy enforcement, and application security tooling all have concrete 2026 milestones attached. This hire closes that gap and has an immediate, visible impact on what the team ships.

What you would do

Build and maintain application security tooling (SAST, which finds vulnerabilities in code automatically, and SCA, which checks third-party libraries for known weaknesses) integrated directly into the engineering workflow
Run threat modeling sessions with product and platform teams, helping them identify how their systems could be attacked before code is written, not after
Own and improve cloud security controls on Azure, including policy-as-code enforcement (automated rules that flag or block insecure configuration before it reaches production) and secure-by-default configuration standards
Contribute to supply chain security, making sure the third-party dependencies and delivery pipelines Mews relies on are not introducing risk into the platform
Use AI tooling to accelerate threat modeling analysis, triage vulnerability findings at scale, and build repeatable security review workflows that the broader engineering team can run without a security specialist in the room for every review

AI Fluency Level 3: In this role, that means you have gone beyond using AI for your own productivity. You have looked at how a security function works and redesigned parts of it using AI: building review workflows or detection playbooks that other engineers can follow without a security specialist present every time, and actively checking AI-generated outputs for accuracy rather than accepting them. In security engineering specifically, this includes evaluating AI-generated code for vulnerabilities, using AI to surface threat patterns across large codebases, and knowing when the model is wrong. This is not a role for someone who uses Copilot occasionally; it is a role for someone who has thought carefully about where AI makes security work better and built something repeatable out of that insight.

For more information on AI fluency at Mews, please refer to AI Fluency at Mews: A Comprehensive Guide for Candidates on Confluence.

What you would bring

2-5 years of hands-on security engineering experience in a software company or cloud-native environment, building security capabilities rather than operating existing tooling
Practical experience with application security: SAST, SCA, secret scanning, or container security, with modern tooling (Wiz, Snyk, Semgrep, or similar)
Cloud security experience on Azure, AWS, or GCP, with a preference for Azure given the team's environment
A development or scripting background (Python, .NET, or similar) that lets you read code, reason about security issues in it, and build automation where repetition is slowing things down
AI Fluency Level 3, or the equivalent hands-on experience: you have redesigned a security workflow or review process using AI, built something others can follow, and you actively verify what AI tools give you rather than treating the output as correct by default

Nice to have

Familiarity with threat modeling methodologies such as STRIDE or PASTA
Experience with supply chain security controls (for example, SBOM generation, dependency pinning, or pipeline integrity verification)
Exposure to European cybersecurity compliance frameworks in a technical rather than audit capacity

Life at Mews

We’re an equal opportunities employer. We value teams that reflect the diversity of the customers and communities we serve. Different perspectives make better ideas, stronger products and a more welcoming company.

We also believe transparency is important when deciding if you're the right fit. Mews is an ambitious, high-pressure environment of continuous learning and high standards. Success here requires resilience, adaptability and a willingness to solve difficult problems.

A few things that define how we work:

High autonomy means high responsibility. People are expected to take ownership and drive outcomes. There isn’t a detailed playbook for everything, and that’s part of what makes the work challenging – and rewarding.
Change is constant. We’re growing quickly and adapting as we scale. Teams, processes and priorities continue to evolve, and only people who stay curious and agile will thrive.
We’re remote-first, not relationship-free. Flexibility is core to how we work, but strong relationships still matter. Our teams are global, so we need expert collaborators and communicators to help us move forward together.
AI is an integral part of our processes. It’s not here to steal people’s jobs, but to amplify efficiency and productivity. We’re motivated to proactively use the technology to seek out better ways of working and share our findings with the rest of the company.

If there's anything we can do to support you during the application process, let us know.

We don't discriminate on the basis of race, religion, colour, nationality, gender, sexual orientation, age, marital status, veteran status, disability or any other protected characteristic.

One final thing: don't hold back. If you don't meet 100% of the criteria in this job description but you're certain you could make a big impact, apply. Everyone should have equal access to opportunities, and we're committed to providing an inclusive experience.

If Mews sounds like the kind of environment where you'd thrive, we'd love to hear from you.
