Full-Stack Software Engineer - AI-Native Product Development

Are you excited about building a cybersecurity product that protects organizations from sophisticated email threats?

Do you love frontend development, but also want to own features end-to-end from the user experience to the backend services and data behind it?

Do you thrive in a fast-moving scale-up where priorities evolve, expectations are high, and you have the freedom and responsibility to get things done?

Has AI fundamentally changed the way you develop software and are you constantly looking for ways to use it to build better software, faster?

Then you should definitely read on.

Tasks

In this role, you will

• build and evolve the product our customers use to understand, configure, and operate their email security
• own features end-to-end from the frontend through APIs and backend services to the underlying data
• put particular care into the frontend, creating intuitive and polished user experiences for complex cybersecurity problems
• work across the full stack, with roughly equal exposure to frontend and backend development
• use AI extensively throughout the engineering process to explore, design, implement, test, debug, review, and improve software
• work with technologies including React, Java, PostgreSQL, Elasticsearch, Nginx, and Docker
• take ownership and drive things forward from figuring out what needs to be built to designing, shipping, operating, and continuously improving it
• work closely with product, security, and engineering colleagues, making pragmatic decisions and turning evolving customer and business needs into great product experiences
• shape our product and engineering practices by bringing in your own ideas and challenging existing approaches

Requirements

You should apply if you

• are a strong software engineer who enjoys building complete product features, not just individual components
• genuinely enjoy frontend development and care about creating user interfaces that are intuitive, responsive, and polished
• are equally willing to leave the frontend and work on APIs, backend services, databases, and infrastructure when that's what a feature requires
• are comfortable stepping outside the code when needed whether that means working in design tools, prototyping an interaction, or thinking through a user flow
• are highly proficient in AI-assisted software engineering and use AI as an integral part of how you design, write, test, debug, and review software
• have solid experience with modern frontend development, ideally with React
• have experience developing backend applications; experience with Java, or a comparable language is particularly relevant
• thrive in a fast-moving environment, can make pragmatic decisions with incomplete information, and adapt quickly when priorities change
• have a strong bias toward action: you identify what needs to be done, move things forward, and don't wait for every detail to be specified
• set a high bar for yourself and your work, while knowing when a pragmatic solution today is better than a perfect solution too late
• care about software quality and understand that using AI effectively requires engineering judgment, not less of it
• communicate clearly in English, our main language at work

A big plus would be if you

• have strong experience with React and modern frontend architecture
• have strong experience with Java and its ecosystem
• have worked with technologies from our stack, such as PostgreSQL, Elasticsearch, Nginx, Docker, and Linux
• have a good eye for UX and enjoy turning complex workflows and data into simple, understandable interfaces
• bring experience in cybersecurity, email security, or related technical domains
• have experience building and operating B2B on-premise and SaaS products

Benefits

What we offer you

• a fair and transparent compensation system
• real ownership from day one: the freedom to make decisions, the responsibility to deliver, and the opportunity to have a visible impact
• a fast-moving scale-up environment with short paths from idea to decision to production
• an engineering environment where AI is deeply integrated into how we build software
• the opportunity to have a visible impact on a product that protects organizations from real-world cyber threats
• a hardware budget to accommodate your individual preferences and needs
• hybrid working, flexible working hours, and a great office in Zurich
• regular events, including Tech Talks, company lunches and office events
• five weeks of paid vacation

We are looking forward to hearing from you!

Join us and help build the product that enables security teams to protect their organizations from today's email threats. At xorlab, you'll have the freedom to shape what we build, how we build it, and how we use AI to become better software engineers.

We do not consider applications from recruitment agencies.

Sophisticated email attacks are on the rise, increasing the risk of breaches and creating an overwhelming workload for security teams. GenAI, automation, and cybercrime-as-a-service tools allow bad actors to launch personalized campaigns at scale—quickly and at low cost. Whether it's state-sponsored attackers or organized cybercriminals, one thing remains clear: email is the most effective initial attack vector, making email security a critical challenge for every organization.

xorlab is the only European provider that specializes in detecting previously unknown email threats. Our platform lets security analysts and detection engineers create and manage custom detection rules, enabling faster responses to new threats and greater control over their organization’s attack surface.

With a growing team of 23 professionals, we develop a cutting-edge email security platform trusted by leading banks, hospitals, and tech providers in the automotive, healthcare, and pharmaceutical sectors.
