About RADICL

As the leading provider of Cybersecurity-as-a-Service (CSaaS), RADICL is revolutionizing advanced cyberthreat protection for small and medium-sized businesses (SMBs) in the U.S. Defense Industrial Base (DIB) and other regulated industries. RADICL is ushering in a new era of turn‑key and affordable cyberthreat protection via its AI-powered virtual SOC platform that allows human and digital agents to quickly and seamlessly become SMBs' day‑to‑day compliance and security operations team.

RADICL's turn‑key CSaaS offering uniquely combines compliance management with AI and expert‑driven 24/7 security operations. We guide customers to regulatory and best practice adherence with standards like CMMC and NIST CSF while also delivering 24/7 threat monitoring, deep-spectrum threat hunting, incident response, vulnerability management, and security awareness training.

RADICL is seeking a Senior Software Engineer to join our platform team. You'll design and build API integrations and highly scalable data processing pipelines that power our security data ingestion, handling both structured and unstructured data from diverse security tools and log sources.

You will be integrating log collectors and forwarders (Fluentd, Fluent Bit, Vector, Logstash, Elastic Beats) and working with data from EDR platforms, cloud providers, compliance tools, and other security data sources. Your work will directly impact how quickly and accurately we onboard new data sources and how effectively our AI‑powered virtual SOC delivers threat detection and compliance capabilities.

• Design and build API integrations for ingesting security data from third‑party tools.
• Develop log parsing and data mapping pipelines to normalize structured and unstructured log formats into our unified schema.
• Integrate with log collectors and forwarders (e.g., Fluentd, Fluent Bit, Vector, Logstash, Elastic Beats).
• Create and maintain data mappings between source schemas and our internal data model.
• Optimize ingestion performance and ensure data quality, completeness, and timeliness.
• Contribute to the design of our emerging agentic parsing pipeline (LLM‑powered extraction for complex formats).
• Work with cloud‑native, distributed systems in AWS, GCP, or Azure.

• Data integration: ETL design, RESTful API development, data mapping, and schema design.
• Log parsing: Experience with regex, Grok‑style patterns, and both structured (JSON, CEF, syslog, CSV) and unstructured log formats.
• Log collection: Experience with Fluentd, Fluent Bit, Vector, Logstash, Elastic Beats, or Open Telemetry Collector.
• Programming: Strong proficiency in Go, Kotlin, and/or Type Script.
• Cloud/Infrastructure: Experience with AWS, Azure, or GCP; familiarity with Kafka or streaming pipelines is a plus.
• Security domain: Understanding of SIEM concepts, security tooling (EDR, firewalls), and compliance data (CMMC, NIST).
• Education: Bachelor's degree in computer science, data engineering, or related field (or 3‑6 years of equivalent professional experience).

At RADICL, we prioritize our culture and believe the strongest teams are built through daily, side‑by‑side collaboration. We have a hybrid work model: in‑office M/W/Th with work‑from‑home on Tuesdays and Fridays. Our offices are in downtown Boulder, Colorado. We offer comprehensive benefits including health, dental, vision, 401K, and a responsible PTO plan.
