Sr. Backend Engineer - Language & Runtime

About the Role:

CrowdStrike is one of the largest security software vendors in the world. With close to 10,000 employees, we stop breaches! 

LogScale, a CrowdStrike product, is an index-free, high performance log management system, used both externally and internally by thousands of companies throughout the world.

LogScale along with CrowdStrike’s Falcon platform allows customers to detect, prevent and respond to threats to their cyber security in one place, and you will be integral to giving our customers  and colleagues the tools they need to identify threats and, ultimately, stop breaches.

As our new Senior Software Engineer, you’ll contribute to the LogScale application for observability, log management, and security events.

As a member of the Language & Runtime team, you will primarily be working to extend and modify the runtime behavior of LogScale, by implementing the semantics and internals of the functions of the LogScale Query Language. Here you will be challenged to write code that is:

• Efficient

• Low/no allocation

• Maintainable

• Scalable

You will also generally be improving the LogScale runtime system, in order to ensure the stability and scalability of LogScale as we continue beyond petabyte scale of data ingestion and search. You will be doing this together with your team, which consists of other engineers with a passion for programming languages.  Teams in LogScale have a high degree of ownership - this includes a say in what gets worked on, but also ensuring high quality of the features delivered, by writing automated tests, and by performing manual tests. 

We expect you to be working primarily on the runtime system, but you may also work on our  compiler - including parsing, intermediate representation, and optimization of the LogScale query language - and parts of LogScale that are runtime-adjacent. 

The LogScale backend is written in Scala, but we do not expect you to be proficient in Scala, as there will be room to learn as you build on your expertise from other programming languages.

As a Senior Engineer, you will become a go-to expert in the LogScale Query Language and its pipeline and actively participate in technical discussions when designing new features or extensions to the LogScale query language and runtime systems. As a Senior Engineer, we expect you will  be working with challenging problems with unclear definitions and an open solution space, and while working on new solutions we expect that you will communicate technical decisions through design documents, technical talks and improving our internal documentation.  

We will challenge you by giving you a high degree of autonomy and challenging tasks, but in return we promise you highly skilled colleagues to engage with.

Please note; this is a Hybrid Role (approx 3 days a week in our Aarhus Office) therefore candidates must be located within the Jylland/Jutland to ensure an accessible commute into our Aarhus Office.

What You'll Do:

• Contribute and take leadership of moving our query language and runtime to the next level.

• Develop the LogScale backend in Scala and extend our query language and runtime system.

• Provide technical advice on decisions and research and propose new technologies.

• Lead delivery of new solutions within the team and mentor team members through code reviews, documentation and technical guidance.

• Monitor and follow up on features released to self-hosted customers and on cloud.

• We use LogScale to monitor LogScale and its usage - so you will be building your own tool.

• Work in a team of friendly, trustworthy and knowledgeable colleagues

• Work on cross-team platform-level initiatives and projects.

• Troubleshoot critical production issues.

• Participate in scoping, designing and developing of new features.

What You'll Need:

• A passion for or personal interest in programming/query languages.

• 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 or asking questions.
