• Lead the design and development of cloud-native microservices for our Next-Gen SIEM platform, focusing on detections and UEBA capabilities that can process and analyze trillions of events per day.
• Take end-to-end ownership of complex, high-impact projects across multiple teams, driving technical decisions and providing architectural guidance using collaborative tools like Miro.
• Partner with cross-functional teams to define, design, and implement solutions that enhance threat detection and analysis capabilities. Contribute to the medium-term strategic and technical direction by identifying areas of greatest need, and creating plans for improvement.
• Utilize and integrate technologies such as Go, Kafka, Redis, OpenSearch, PostgreSQL, and more to build robust, scalable solutions.
• Optimize and scale existing systems for improved stability, performance, and reliability across business-critical infrastructure, using monitoring tools like Grafana to track and analyze system metrics.
• Mentor junior engineers through pair programming, code reviews, and knowledge sharing, fostering a culture of technical excellence. Additionally, participate in the interview process and coach/mentor new interviewers to maintain high hiring standards.
• Champion software engineering best practices to ensure high-quality deliverables, including robust testing strategies, effective code reviews, comprehensive documentation, continuous integration/deployment, and adherence to architectural principles that promote scalability and maintainability.
• Participate in and lead technical working groups that influence the broader Product team or industry.
• Provide monitoring and operational support for production services, including participating in an on-call rotation for one week approximately every 10-12 weeks.
• Be given the autonomy to own your work in a high trust environment, managing tasks and priorities effectively using Jira.

What You’ll Need:

• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field, or equivalent experience.
• 10+ years of experience in software development, with a focus on cloud-native architectures and distributed systems.
• Expert-level proficiency in at least one modern programming language such as Go (preferred), Python, Java, or C#.
• Demonstrated experience in designing and implementing large-scale, high-performance data processing systems.
• Strong understanding of security concepts, threat detection methodologies, and UEBA principles.
• Proven track record of leading complex technical projects and delivering results on schedule.
• Experience with cloud platforms (preferably AWS) and containerization technologies like Docker and Kubernetes.
• Excellent communication skills, with the ability to explain complex technical concepts to both technical and non-technical audiences.
• A collaborative mindset and the ability to work effectively across teams and disciplines.

Bonus Points:

• Prior experience working in cybersecurity or intelligence fields.
• Experience in developing or working with SIEM or log management solutions.
• Experience with big data technologies such as Kafka, OpenSearch, Cassandra, Spark, or Flink.
• Familiarity with machine learning and AI techniques applied to cybersecurity.
