We are seeking a Principal Engineer to architect and build large-scale, real-time data systems that power a modern security platform. This is a high-impact, high-ownership role where you will lead core architectural decisions, design distributed streaming infrastructure from the ground up, and shape long-term technical strategy.
You will operate at the intersection of real-time data processing, distributed systems, and security intelligence—solving complex engineering problems at scale. This opportunity is ideal for someone who thrives in ambiguity, takes end-to-end ownership, and has experience building scalable systems in security or related domains.
RequirementsKey Responsibilities
- Architect and develop large-scale real-time data processing systems using Apache Flink
- Design highly reliable, low-latency distributed systems capable of handling high-throughput workloads
- Write production-grade code in Java and/or Rust
- Lead system design discussions and define engineering standards and best practices
- Own scalability, performance optimization, reliability, and observability across services
- Mentor engineers and elevate the technical quality of the team
- Collaborate closely with product and security stakeholders to translate requirements into resilient technical solutions
- Drive long-term architectural decisions and contribute to technical roadmap planning
- 8+ years of experience building backend or distributed systems
- Strong hands-on expertise with Apache Flink
- Advanced programming skills in Java
- Production experience with Rust
- Deep understanding of distributed systems, streaming architectures, and real-time data pipelines
- Experience building high-throughput, low-latency systems
- Strong foundations in system design, concurrency, and performance optimization
- Experience in cybersecurity, threat detection, observability, or data security domains
- Background in processing high-volume event streams (logs, telemetry, network data)
- Familiarity with Kafka, stateful stream processing, and real-time analytics
- Experience in high-growth or early-stage startup environments
- Proven track record of building systems from 0 → 1 or significantly scaling existing platforms
- High ownership over foundational architectural decisions
- Opportunity to build and scale mission-critical infrastructure
- Work on complex, real-world security challenges
- Collaborate within a small, high-caliber engineering team
- Direct influence on product direction and long-term technology strategy
