Senior Software Engineer at RADICL – Boulder | Jobyssey

About the role

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'll 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. You will also be a key part of implementing our agentic automation for parsing and mapping dynamic data sources.

If the above excites you, RADICL Defense is seeking high performing, motivated individuals to join our mission. As an early member, you will work closely alongside an experienced founding team and realize the life-changing experience of building a company. You will work with the latest technologies in software, cybersecurity, and cloud and will have a significant impact on the formation of our platform and offering.

About You
You enjoy fast-paced environments, bring a positive attitude, and excel at getting things done. You enjoy being part of a high performing team and are also able to self-direct and self-start.

You enjoy working with customers, are an excellent communicator, and able to engage and interact with people of various backgrounds and skill levels. You want your work to have meaning, to be important. You want to be part of creating something great.

As a RADICL Senior Software Engineer, you will:

Cloud-native, distributed systems — reliability, performance, and security in AWS, GCP, or Azure; microservices; Docker and Kubernetes; CI/CD (e.g. GitHub Actions).

Architecture and quality — help shape how systems connect; code review, testing, documentation, and clear tradeoffs in multi-tenant, mission-critical environments.

Design and build API integrations for ingesting security data from third-party tools (EDR, cloud providers, compliance platforms, and other security data sources)

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

Document integration specifications and support internal and external stakeholders with technical guidance

Contribute to the design of our emerging agentic parsing pipeline (LLM-powered extraction for complex formats)

Your skillset/experience should include:

Data integration fundamentals: ETL design, RESTful API development, data mapping, and schema design

Log parsing and normalization: Experience with regex, Grok-style patterns, or similar; comfort with both structured (JSON, CEF, syslog, CSV) and unstructured log formats

Log collection/forwarding tools: Experience with one or more of Fluentd, Fluent Bit, Vector, Logstash, Elastic Beats (Filebeat, Winlogbeat), OpenTelemetry Collector, rsyslog, or syslog-ng

Security data platforms: Familiarity with security data ingestion patterns; experience with Splunk, Microsoft Sentinel, Graylog, Sumo Logic, Google Chronicle, IBM QRadar, or similar platforms is valuable

Programming: Strong proficiency in Go, Kotlin, and/or TypeScript

Data modeling: Ability to design schemas for security/observability data; familiarity with Elasticsearch and Elastic Common Schema or similar is a plus

Cloud and infrastructure: Experience with AWS, Azure, or GCP; familiarity with Kafka or streaming pipelines is a plus

Security domain awareness: Understanding of SIEM concepts, security tooling (EDR, firewalls, cloud logs), and compliance data (CMMC, NIST) is highly valued

Agentic/AI pipelines: Interest or experience with LLM-based data extraction (nice-to-have)

Education: Bachelor's degree in computer science, data engineering, or related field—or equivalent professional experience (typically 3–6+ years)You don’t need to match every item on this list to apply. If this work sounds like what you want to do, and you have strong Go plus real experience shipping with Terraform or GitHub Actions, we want to hear from you.
