Job description

As a global leader in cybersecurity, CrowdStrike protects the people, processes and technologies that drive modern organizations. Since 2011, our mission hasn’t changed — we’re here to stop breaches, and we’ve redefined modern security with the world’s most advanced AI-native platform. We work on large scale distributed systems, processing almost 3 trillion events per day and this traffic is growing daily. Our customers span all industries, and they count on CrowdStrike to keep their businesses running, their communities safe and their lives moving forward. We're proud to work for a mission-driven company leveraging AI to transform the way we work. CrowdStrikers drive their careers through flexibility and autonomy while also being expected to contribute to a culture of responsible AI adoption, experimentation, and innovation. We use an AI-first mindset as a force multiplier to proactively and continuously accelerate execution, build expertise, uncover insights, and solve complex problems. We’re always looking to add talented CrowdStrikers to the team who have limitless passion, a relentless focus on innovation and a fanatical commitment to our customers, our community and each other. The future of cybersecurity starts with you.

About the Role: Our mission is to make all of our customers’ security‑relevant data continuously available for automated detection and response, threat hunting, and other Falcon use cases. To enable this, the systems behind NG‑SIEM are growing to accommodate >100 PB of event and action data ingested every day, up to 10 years of retention, and dozens of millions of queries per hour across large sections of the data stored. As a new Senior Engineer on the LogScale Search team you will be responsible for delivering this scale to customers by developing new features as well as improving existing functionality. You will be joining a distributed team of highly collaborative engineers who share a strong passion for the product. In this role you will get a chance to work on hard engineering problems that do not have well‑defined solutions. You will become one of the go‑to experts of the LogScale, and will have a broad understanding of the entire LogScale architecture. Teams in LogScale have a great amount of autonomy, and own a part of the LogScale experience, from ideation and development to deployment and feedback. This includes ensuring high quality of the features they deliver, by writing automated tests, and performing manual tests. Moreover, we do not just throw over features to our operations teams, but we constantly observe and monitor new features in production, with LogScale dashboards of course. An important part of our work is making sure that LogScale continues to be scalable in terms of efficiently ingesting and digesting events, querying for the right data, while also ensuring the stability of the clusters. This role is hybrid, requiring 2-3 days per week on‑site at our Aarhus Office.

What You’ll Do

• Work in a team of friendly, trustworthy and knowledgeable colleagues supporting each other through code reviews, pairing, documentation, design reviews and technical guidance.
• Lead by example on customer and product focus, as well as on hands‑on operational excellence by monitoring and following up on features released to customers and troubleshooting critical customer issues.
• Deliver cross‑team platform‑level initiatives and projects by owning or participating in scoping, designing and developing of new features to open‑ended problems.
• Develop the LogScale backend in Scala and extending our product to keep LogScale scale with increasing ingest and query load while ensuring high availability.
• Collaborate with your peers across teams on defining and delivering new solutions, design documents, technical talks and improving our internal documentation.
• We are a global company so you must bring your excellent verbal and written communication skills to bear when you are working with teams across the globe.

What You’ll Need

• A passion for or personal interest in distributed systems and curiosity of how our running systems are doing.
• Experience in software development in general and the ability to juggle making pragmatic tradeoffs between short‑time delivery needs vs long‑term product goals.
• Experience in contributing to broad technical leadership in products or services.
• Fluency in both functional and object‑oriented programming and the ability to pick up new languages on the go.
• A can‑do attitude, and that you thrive collaborating in a team and are not afraid of taking on responsibilities.
• Demonstrated track record of operational excellence when operating services that span many components across several geographical regions; Ability to communicate and articulate technical concepts crisply to individual contributors and management.
• Proven experience utilizing AI technologies to enhance decision‑making, streamline workflows and processes, improve efficiency and drive business outcomes.

Bonus Points

• Experience programming in Scala.
• Experience with commercial clouds (AWS, Azure, GCP).
• Experience with Kafka.
• Hands on experience in large‑scale (distributed) system architecture, high scalability and availability, and optimization - over 1 trillion requests per day or more than 10 PB of data per day.

CrowdStrike was founded in 2011 to fix a fundamental problem: The sophisticated attacks that were forcing the world’s leading businesses into the headlines could not be solved with existing malware‑based defenses. Founder George Kurtz realized that a brand new approach was needed — one that combines the most advanced endpoint protection with expert intelligence to pinpoint the adversaries perpetrating the attacks, not just the malware. There’s much more to the story of how Falcon has redefined endpoint protection but there’s only one thing to remember about CrowdStrike: We stop breaches.
