Senior DevSecOps / Platform Security Engineer (AWS + Kubernetes)

📋 Description • Join Red Cell Partners, an innovative incubation firm dedicated to building and investing in rapidly scalable technology-led companies that are driving revolutionary advancements in healthcare, cyber, and national security.

We are united by a shared sense of duty and a deep belief in the power of innovation to address our Nation’s most pressing problems. • Within this dynamic environment, you will be instrumental in shaping the future of DEFCON AI, a cutting-edge modeling, simulation, and analysis (MS&A) company focused on generating operationally relevant insights for next-generation logistics and mobility decision-making.

We are a mission-focused team of world-class AI Engineers, mobility, and logistics experts committed to developing solutions that help partners better prepare for contested mobility disruptions. • We are seeking a senior, hands-on DevSecOps/Platform Security Engineer to architect, build, and operate production security controls across our AWS and Kubernetes platform.

This is a critical role where you will have significant ownership and the opportunity to make a tangible impact on our security posture. • Your primary responsibility will be to design and implement robust guardrails that ensure secure delivery is the default for all our development processes.

This includes automating security within CI/CD pipelines, establishing comprehensive software supply chain controls, and enforcing stringent Kubernetes policies. • You will collaborate closely with our Platform/SRE and Security/GRC teams, acting as a bridge between development, operations, and security compliance.

You will not just be making recommendations; you will be shipping code and infrastructure, owning the reliability and outcomes of the security controls you build. • You will participate in an on-call rotation and respond to incidents related to platform security controls and pipeline reliability, with the scope aligned with the Platform/SRE team.

This includes translating requirements from standards like NIST SP 800-171 and CMMC expectations into practical, automated guardrails within our CI/CD, AWS, and Kubernetes environments. • We foster a pragmatic, automation-first approach where security is built-in by default, with low-friction workflows for developers.

We partner closely with Platform/SRE and Security/GRC, focusing on clear ownership and measurable outcomes. • Our focus is on building durable systems, creating scalable guardrails, templates, and controls that benefit all teams.

You will be instrumental in improving signal-to-noise ratios rather than adding unnecessary friction. • We value analytical aptitude, effective communication, adaptability in a fast-paced tech landscape, and experience with agile methodologies.

While a formal education is a plus, we prioritize hands-on experience and demonstrable skills.

A commitment to continuous learning is essential as you stay aligned with the latest technology trends and best practices. 🎯 Requirements • 5+ years of experience in DevOps/SRE/Platform Engineering and/or Security Engineering with a strong automation and delivery focus.
