​This is a full-time, Hybrid role based in Overland Park, KS. Mariner is a high-growth financial services firm (advising on over $560B) that prioritizes an “engineering-minded” approach to security. This role is designed for a technically curious practitioner who wants to work under leadership that understands hands-on workflows and trade-offs. You will be responsible for building, optimizing, and running security platforms in a high-rigor, highly regulated financial environment.

• ​Location: Overland Park, KS (Hybrid).
• ​Experience Required: 3–5 years in information security, IT operations, or engineering.
• ​Core Focus: Platform engineering, identity architecture (Okta), and automation.
• ​Environment: Financial Services; modern architectures with a focus on precision and repeatability.
• ​Culture: Fast-moving, autonomous, and focused on “security by design.”

​Key Responsibilities: Engineering and Operational Excellence

​The role balances the technical “run” of security tools with the “build” of new capabilities and automated workflows.

​Platform Engineering and Optimization

You will implement and optimize enterprise-level tooling across detection, identity, cloud, and endpoint technologies. This isn’t just monitoring; it’s about engineering the platforms to work more effectively through continuous refinement.

​Deep-Dive Assessments

Conduct hands-on testing of systems, configurations, and architectures. You will provide actionable insights that influence how the broader engineering and business teams make technical decisions.

​Core Security Operations

Support and mature the “bread and butter” of SecOps, including:

• ​Malware Response: Handling remediation and recovery.
• ​Vulnerability Management: Managing patch governance and risk analysis.
• ​SIEM Analysis: Log correlation, trend monitoring, and incident documentation.

​Identity and Automation

A significant portion of the role involves IAM (Identity and Access Management), specifically using Okta to integrate applications and security systems. You will use Python, PowerShell, or Bash to automate response actions and streamline security workflows.

​What You Bring: Technical Profile

​Mariner is looking for an analyst who is ready to step into an engineering mindset, with a high bar for detail and documentation.

• ​Education: Bachelor’s degree in CS, InfoSec, or equivalent experience.
• ​Tooling Knowledge: Familiarity with SIEM, EDR, and Vulnerability Scanners.
• ​Identity Mastery: Hands-on familiarity with Okta or similar IAM solutions.
• ​Framework Fluency: Knowledge of NIST, CIS, and ISO 27001 standards.
• ​Automation Skills: Ability to write scripts (Python, PowerShell, or Bash) to remove manual toil from security processes.
• ​Soft Skills: Exceptional communication skills and the ability to operate with high autonomy in a fast-paced environment.

​Why This Role is Unique

• ​Engineering-First Leadership: Report to leaders who have been hands-on and understand the technical constraints of the job.
• ​Broad Domain Depth: Gain exposure to everything from detection engineering to cloud-native security and identity architecture.
• ​State-of-the-Art Access: Work with advanced automated response tooling and emerging standards in a high-stakes financial context.
