Company mission
Expel is on a mission to make security easy to understand, easy to use, and easy to continuously improve.
Role
Who you are
- You find beauty in turning chaotic, unstructured data into a perfectly organized and enriched stream of information
- You're excited by the challenge of processing billions of events in real-time, where every millisecond counts
- You want to build the system that transforms raw noise into the clear signals our security analysts use to stop attackers
- A passion for data quality and a deep appreciation for the power of a well-designed data model
- An obsession with performance, latency, and building highly efficient, real-time systems
- Professional experience developing in Go and/or Python
- Expertise in real-time data processing and stream-based architectures (e.g., Kafka, Flink, Beam) and data serialization formats (e.g., Avro, Protobuf)
- Proven experience with data modeling, and an understanding of (or strong desire to learn) common information models like OCSF
- Hands-on experience with cloud and data technologies like Google Cloud (BigQuery, Pub/Sub) or AWS equivalents
- The ability to lead through influence, communicate complex ideas clearly, and mentor other senior engineers
- Typically 10+ years of professional software engineering experience
What the job involves
- We're looking for a Principal Engineer to lead the technical architecture of our Data Normalization and Enrichment services
- This isn't just a data pipeline role; it's the critical link between the raw data we ingest from our customers and our ability to perform lightning-fast threat detection
- You will be responsible for the high-throughput, low-latency systems that give our data meaning and context
- The quality and structure of the data you produce will directly impact our ability to protect our customers from threats
- Your work is the foundation of our detection strategy
- This role will architect and own the real-time systems that transform a firehose of raw security logs into a perfectly structured, enriched, and analysis-ready data stream
- Become our expert on security data schemas, leading the charge on data modeling and the adoption of common information models like the Open Cybersecurity Schema Framework (OCSF)
- Drive the technical strategy for enriching our data, integrating threat intelligence and other contextual information to make our detection capabilities smarter
- Collaborate closely with our detection and response engineers to understand their needs and deliver data that empowers them to find and stop threats faster
- Lead and mentor other engineers, setting the bar for building performant, resilient, and scalable data transformation systems
- We build and run teams where everyone is pulling in the same direction and is learning from each other:
- We work out of a shared backlog
- We peer-review everything
- We pair-program when it makes sense
- We do regular blame-free retros
Our take
As ransomware and hacking threats rise, identifying and resolving breaches in security must be done quickly. Lack of transparency in cyber-security makes it difficult for engineers to detect, understand, and fix the issues as fast as possible. Expel is aiming to redefine what a security operations center and managed detection service looks like in the modern age.
Though the company faces competition from the vast number of cybersecurity platforms, Expel positions itself as a viable alternative to the service delivery model of managed security service providers (MSSPs) by offering a comprehensive management platform that connects to its customers’ tech remotely through APIs, providing fast detection and clear solutions.
Having reached unicorn status, the company is establishing a stronger presence in the European and Asia-Pacific markets, capturing business in Canada, the United Kingdom, Australia, and Singapore. Its 2022 funding is being used to accelerate sustainable growth, continue the company's international expansion, and push forward with go-to-market initiatives.
