About the role

RADICL is seeking a Senior Engineer to focus on AI-driven workflows and intelligent automation systems. You'll architect and build the next generation of automated incident response capabilities powered by advanced AI systems. This role is entirely focused on automation and workflow orchestration - you'll create intelligent systems that automatically process security data, generate insights, and execute response actions without direct human interaction in the critical path.

You'll work on automated case management systems that combine large language models, threat intelligence, entity attribution analytics, and automated reasoning to accelerate incident response. Your work will directly impact how our platform automatically processes threats, correlates entity relationships, and executes response workflows at scale. Your focus will be on automated intelligence and case processing systems that consume security data feeds to drive autonomous security operations.

If building AI systems that enhance human decision-making in high-stakes security environments excites you, RADICL is seeking high-performing, motivated individuals to join our mission. As an early member, you will work closely alongside an experienced founding team. You will work with the latest AI/ML technologies and cybersecurity platforms. You will have a significant impact on the growth of an innovative cybersecurity offering in the SMB space. You will receive an outsized equity grant and realize the life-changing experience of building a company.

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 consider yourself to be top tier talent and are eager to help others raise their game.  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 Engineer - AI-Driven Workflows, you will:

• Automated incident response — design and build intelligent case management systems that automatically triage security incidents, generate threat context reports, and execute response actions without human intervention in the critical path
• Agentic workflow orchestration — develop sophisticated agent systems using large language models (LLMs) that autonomously reason about security data, correlate threat patterns, and execute complex investigation workflows
• Deterministic automation pipelines — create reliable, event-driven systems that learn from AI feedback to improve decision-making, automate response actions, and ensure consistent incident processing at scale
• Automated intelligence processing — create systems that consume security data feeds, automatically enrich indicators of compromise (IoCs), correlate threat intelligence, and generate actionable insights without manual intervention
• Multi-modal data integration — develop systems that correlate structured security data, unstructured threat intelligence, and analyst feedback to continuously improve AI model performance and workflow reliability
• Real-time streaming workflows — implement event-driven architectures using Kafka that process security alerts, enrich threat data, and trigger appropriate AI-driven responses in real-time
• LLM integration and optimization — work with AWS Bedrock, Azure OpenAI, and other AI platforms to optimize model selection, prompt engineering, and cost-effective AI operations at scale

Your skillset/experience should include:

• AI/ML systems experience: 3+ years implementing production AI workflows, preferably with large language models, agent systems, or intelligent automation platforms
• LLM integration: Hands-on experience with GPT, Claude, or similar models; understanding of prompt engineering, fine-tuning, and AI safety considerations
• Event-driven architecture: Strong background in designing reliable, scalable systems using message queues (Kafka), stream processing, and asynchronous workflows
• Go and Python proficiency: Experience building high-performance backend services in Go and AI/ML pipelines in Python; familiarity with frameworks like LangChain, LlamaIndex, or similar
• Security domain knowledge: Understanding of automated incident response workflows, entity relationship modeling, threat attribution methodologies, and cybersecurity operations
• Data systems: Experience with Elasticsearch/OpenSearch, PostgreSQL, and handling large-scale security data processing and analysis
• Deterministic system design: Ability to build reliable, testable systems that incorporate AI feedback while maintaining predictable behavior and auditability
• API design: Experience designing RESTful APIs and real-time interfaces (WebSockets, SSE) for automated AI workflow systems and data processing pipelines
• Cloud platforms: AWS experience, particularly with Bedrock, Lambda, ECS, and other AI/ML services
• Workflow automation: Understanding of business process automation, rule engines, and creating configurable, repeatable workflows
• Testing AI systems: Experience with testing strategies for AI-powered applications, including prompt testing, model validation, and regression detection

Nice to have:

• MLOps experience with model deployment, monitoring, and lifecycle management
• SOAR platform experience (Phantom, Demisto, etc.) or security orchestration background
• Threat intelligence experience with automated IoC enrichment, entity correlation, MISP, STIX/TAXII, or threat attribution analytics
• React/TypeScript for building AI-powered user interfaces
• Vector databases and semantic search for security data correlation
• Graph databases or knowledge representation for threat modeling

About the Workplace
At RADICL, we prioritize our culture and believe the strongest teams are built through daily, side-by-side collaboration and experiential sharing. We also value individual freedom and flexibility. For this reason, we have a hybrid work model. As a team, we are in office M/W/Th with work-from-home on Tuesdays and Fridays. For remote positions, periodic travel to Boulder will be expected to participate in company events and meaningful side-by-side collaboration opportunities.

RADICL offices are in downtown Boulder, Colorado with easy-to-access employee parking provided by the company. We offer comprehensive, competitive benefits including health, dental, and vision as well as 401K and a responsible PTO plan.
