Our team brings together talent from intelligence, military, tech, and consulting backgrounds — all united by a shared mission: to make enterprise-grade cybersecurity accessible to every business, not just the big players.

About this role

We are looking for Senior Software Engineers (f/m/x) to act as trusted technical leaders, driving decisions that shape our teams, product, and business forward.

You will work with a high degree of autonomy, turning high-level goals into technical plans, leading the design and execution of complex systems, and mentoring junior engineers to raise the bar across the team.

This role is a chance to make a real difference in a fast-growing scale-up environment, where your work will directly shape both our product and our engineering culture.

What you will do

• Design and develop features that deliver real-world value.

• Turn high-level goals into actionable technical plans without close supervision.

• Make informed trade-offs across technical complexity, ROI, user impact, and time-to-market.

• Act as a go-to engineer, helping peers navigate difficult technical problems.

• Lead design and architecture discussions with a focus on performance, security, and maintainability.

• Deliver outcomes that impact product and business metrics, not just technical outputs.

• Mentor junior and mid-level engineers through pairing, feedback, and guidance.

• Contribute to team culture by sharing knowledge and raising engineering standards.

• Advocate for clarity when the “why” is unclear, keeping the team focused on the most valuable problems.

• Communicate effectively with technical and non-technical stakeholders.

What you need

• 6+ years of development experience in a strongly typed language (Typescript, Java, .NET, PHP). We operate in Go and React, and believe a seasoned engineer with strong fundamentals can adapt quickly.

• Proven ability to take initiative, solve complex problems, and deliver in ambiguous environments.

• Strong knowledge of APIs and cloud infrastructure (AWS preferred).

• Experience with CI/CD and DevOps practices.

• Skilled at breaking down complex problems into practical, actionable solutions.

• Strong engineering skills with an analytical mindset and product awareness, making decisions that deliver the greatest impact.

• Excellent communication and collaboration skills.

• Fluency in English is a must.

What we offer

• A meaningful mission: protect organizations across Europe from real-world cyber threats

• Work with top-tier professionals from national CERTs, intelligence agencies, and leading tech backgrounds

• A remote-friendly culture with quarterly meetups and annual company retreats (in Spain, Portugal, Italy…)

• Weekly lunches (NL) and Thursday socials to stay connected

• A generous time-off policy, including wellbeing and volunteering days
