Remote, Full-time

We are seeking a Backend Java Engineer to join our growing group! Our Alerting engine powers large-scale, real-time streaming detection, handling millions of events per second with sub-second latency to identify incidents as they occur. Built on a distributed, event-driven architecture, it supports sophisticated pattern evaluation, dynamic data enrichment, and resilient delivery for mission-critical observability needs.

About:

We are a cutting-edge, full-stack observability platform transforming how organizations process and derive value from their data. Our architectural design enables real-time stream analytics without the burden of high-cost indexing or hot storage. We focus on end-to-end monitoring across logs, metrics, traces, and security events—offering capabilities like APM, RUM, SIEM, and Kubernetes infrastructure monitoring—all designed to boost operational efficiency while reducing observability expenses by up to 70%.

Responsibilities:

• Spearhead the design, construction, and evolution of high-impact, scalable systems;
• Take complete ownership of features across the entire lifecycle, ensuring reliable performance in production from initial concept through deployment;
• Address complex engineering challenges at scale by applying solid technical practices and modern stream-processing frameworks;
• Partner closely with software engineers and product management to continuously refine and enhance the product;
• Drive both technical excellence and tangible value for end users.

Requirements:

• 5+ years of professional software engineering experience;
• 3+ years of development experience within the JVM ecosystem (Java / Kotlin / Scala) — an advantage;
• 3+ years of experience building and running distributed systems in production environments;
• Hands-on experience utilizing observability tools (such as Coralogix, Grafana, etc.);
• Proven track record of architecting highly available, resilient systems through solid design principles, comprehensive monitoring, and proactive incident response;
• Hands-on experience with data streaming technologies (e.g., Apache Kafka, Spark Streaming, KafkaStreams, or Apache Flink);
• Strong expertise in data modeling and designing architectures capable of efficiently handling large, distributed datasets;
• Deep understanding of distributed computing concepts, including consistency, partitioning, and fault tolerance;
• B.Sc. in Computer Science or an equivalent technical field;
• At least Upper-Intermediate English level.

Would be a plus:

• Familiarity with gRPC and Protobuf;
• Practical experience with RocksDB tuning and performance optimization;
• Production experience operating in a SaaS environment (metrics collection, logging, and production troubleshooting).

We offer:

Growth: Udemy corporate access, corporate English program, and educational meetups from partners. Health: Medical insurance, psychological support, and fitness discounts.

Comfort: 100% paid vacation days and sick leaves and power-independent offices (Generators/Starlink).

Beyond Work: Free legal advice, referral bonuses, and loyalty program.
