Introduction

A TeamStation AI partner in the social and community technology sector is seeking a Senior Fractional DevSecOps / Application Security Lead. You’ll establish the security foundation for an early-stage platform while helping a small development team build effectively without production access, cloud-administrator permissions, live credentials, customer data, or direct push access to main branches.

This is a hands-on leadership role for someone who can define the security strategy, implement practical controls, and guide developers-not simply produce an audit that spends the rest of its life in a folder.

What You’ll Do

• Review the planned development workflow and create a practical, build-ready DevSecOps control plan.
• Design secure development, staging, and production separation with appropriate sandbox and access-control models.
• Establish least-privilege cloud roles, repository permissions, branch protections, pull-request approvals, and main-branch restrictions.
• Define secrets-management processes and CI/CD guardrails for static analysis, dependencies, container images, vulnerabilities, and exposed secrets.
• Recommend infrastructure-hardening, logging, auditing, and vulnerability-management practices across cloud resources and developer platforms.
• Create onboarding and offboarding checklists, a security-review model for developers, and an implementation roadmap with estimates, assumptions, dependencies, and risks.

Tech Stack & Tools

Cloud and access control:AWS, AWS Identity and Access Management

Secrets-management experience:AWS Secrets Manager, AWS Systems Manager Parameter Store, HashiCorp Vault, or an equivalent platform

Accepted source-control experience:Bitbucket, GitHub, or GitLab

The detailed platform stack, architecture, and security design will be disclosed under NDA on a need-to-know basis.

What You Bring

• Senior-level experience securing cloud applications and establishing DevSecOps practices.
• Hands-on experience implementing branch protections, pull-request approval workflows, and separate development, staging, and production environments.
• Proven ability to implement least-privilege AWS access controls and secure secrets-management processes.
• Experience implementing CI/CD controls such as SAST, SCA, dependency scanning, image scanning, vulnerability detection, or secrets scanning.
• Practical knowledge of secure application architecture, infrastructure hardening, security reviews, and vulnerability management.
• Ability to review developers’ work, explain security concerns clearly, and produce useful plans, diagrams, access matrices, READMEs, and checklists.
• Willingness to use company-owned accounts and provisioned sandboxes, track hourly work, document milestones, obtain approval for significant estimate changes, and secure written authorization before using AI tools or third-party automation with partner materials.

Bonus Points

These are preferences, not requirements. Candidates can qualify without them.

• Experience establishing DevSecOps or application-security controls in banking, financial services, healthcare, or another regulated or security-sensitive industry.
• Experience guiding a small development team in an early-stage, founder-led environment.

What’s in It for You

• A part-time engagement expected to span approximately four to five months.
• A clearly bounded initial discovery and planning phase expected to require 5-10 hours unless otherwise approved.
• The opportunity to establish the security architecture, operating controls, and development practices for an early-stage platform.
• Potential ongoing involvement in implementation, pull-request reviews, access governance, and developer security guidance.

Apply

If you know how to turn rigorous security expectations into controls that a development team can follow every day, we’d like to hear from you.
