Job description

This position requires an active TS/SCI clearance with a current Full Scope Polygraph at the time of application. Due to the nature of the work and U.S. Government contractual requirements, applicants must be U.S. citizens and must be able to maintain the required clearance for the duration of employment. Candidates without an active in-scope clearance and polygraph cannot be considered, and we are unable to sponsor clearances for this role.

About the Role

Agentic Defense Solutions, Inc. is seeking a Principal DevSecOps Engineer to lead the team that builds, secures, and operates the delivery pipeline and cloud infrastructure behind large-scale data ingest and analytics platforms in accredited environments.

This is a dual-track role. Roughly [60]% of your time is hands-on engineering: you will design the pipelines, write the automation, and own the architecture. The remaining [40]% is leadership: you will manage a team of engineers, own their growth and performance, plan staffing against contract scope, and serve as a senior technical voice with the government customer.

The distinguishing requirement is that security is your job, not the job of a team you hand off to. We are looking for someone who builds pipelines where hardening, scanning, and control evidence are automated products of the build itself - and who can then sit across from an Authorizing Official and defend how it works.

What You'll Do

Engineering & Architecture

• Own the architecture of the CI/CD pipeline supporting multiple microservice development teams - build, artifact management, automated test and security gating, and promotion through environments to production.
• Own infrastructure-as-code and configuration management; environment builds are reproducible, version-controlled artifacts, never hand-tuned systems.
• Design and operate automated deployments of large-scale distributed data and AI infrastructure including capacity planning, scaling policy, and upgrade strategy.
• Implement low- and zero-downtime deployment strategies with automated rollback driven by health and performance signals.
• Build self-healing automation: instrument the platform for known instability patterns and implement corrective actions that fire automatically instead of paging a human.
• Engineer and tune cloud infrastructure (compute, object storage, load balancing, autoscaling, monitoring, notification) for throughput, resilience, and cost.
• Build and maintain observability - metrics, logging, distributed tracing, alerting - and drive down mean time to detection and recovery.

Security Engineering

• Embed security throughout the pipeline: SAST, DAST, software composition analysis, secrets scanning, IaC scanning, and container image scanning, with risk-based gating and a defensible exception process.
• Automate system hardening - STIG and benchmark application, drift detection, and remediation as code rather than as a checklist.
• Own supply-chain integrity: SBOM generation, dependency provenance, artifact signing, and trusted base image management.
• Design and operate secrets and key management (vaulting, rotation, brokered credentials); eliminate static credentials from the pipeline.
• Implement container and orchestration security - image hardening, admission control, network policy, runtime detection.
• Drive vulnerability management end to end: discovery, triage, patch automation, and closure tracking against POA&M commitments.
• Implement NIST SP 800-53 controls as automated, continuously evidenced capabilities; generate accreditation artifacts from pipeline telemetry rather than assembling them by hand.
• Partner with ISSM/ISSO staff and interface directly with the SCA and Authorizing Official on control implementation, risk positions, and the path toward continuous ATO.
• Lead threat modeling of the build and deployment pipeline itself, and remediate what it surfaces.
• Manage a team of [4-8] DevSecOps and platform engineers: set direction, assign work, review output, and hold the technical bar.
• Own performance management for the team - goal setting, regular feedback, formal reviews, promotion and compensation recommendations, and corrective action when needed.
• Own career development: identify growth paths, assign stretch work, and manage the team's training and certification plan (including clearance and 8140 currency).
• Lead technical hiring for the team - define requirements, interview, assess, and close candidates in a very constrained cleared labor market.
• Plan staffing and labor allocation against contract scope and funding; forecast needs and flag gaps to program management before they become schedule risk.
• Contribute to budget planning, level-of-effort estimation, and basis-of-estimate development; manage subcontractor or teammate technical scope where applicable.
• Serve as a senior technical interface to the government customer on architecture, roadmap, operational status, and security posture.
• Establish engineering standards, reference patterns, and documentation that outlast any individual on the team.
• Support capture and proposal efforts as a technical SME, including solution architecture and technical volume input.

Required Qualifications

• Active TS/SCI with Full Scope Polygraph .
• 12+ years of progressive IT/engineering experience
• Minimum 6 years in DevOps, DevSecOps, platform engineering, or SRE, including direct ownership of production CI/CD pipelines.
• Minimum 3 years of formal or acknowledged technical leadership - managing engineers, leading a team, or serving as the technical authority others elevate to. Direct people-management experience strongly preferred.
• Hands-on depth building and operating CI/CD toolchains - e.g., Jenkins (or GitLab CI/equivalent), Git/GitLab, an artifact repository such as Nexus or Artifactory , and configuration management such as Ansible .
• Production experience with AWS core services (EC2, S3, ELB/ALB, Auto Scaling, CloudWatch, SNS, IAM) and with automating their provisioning.
• Demonstrated experience deploying and operating at least one large-scale distributed data or AI technology in production
• Demonstrated experience integrating security tooling into a delivery pipeline (SAST/DAST/SCA, image scanning, compliance scanning) with meaningful gating.
• Strong automation engineering in Python and shell; you write and maintain real tooling, not just glue.
• Working knowledge of NIST SP 800-53 , the RMF lifecycle, and STIG application in a classified or otherwise regulated environment.
• Experience deploying and operating microservice architectures , including service discovery, gateway/routing patterns, and inter-service resilience.
• Experience taking a system to ATO in a cloud environment , or standing up a continuous ATO (cATO) pipeline.
• Infrastructure-as-code with Terraform, CloudFormation, or equivalent; compliance-as-code with InSpec, OpenSCAP, or equivalent.

About Agentic Defense Solutions Inc

Agentic Defense Solutions exists to solve the real problem in mission-critical AI: not better models, but the operational trust layer that makes AI governable, auditable, and safe to deploy in high-consequence environments.

Our Mission

Most people think the challenge in mission-critical AI is better models. It isn't. The real problem is there is no control plane for how AI reasons, makes decisions, and executes operations in high-consequence environments.

Agentic Defense Solutions builds the ARIA product family: the operational trust layer for AI where decisions have real-world impact. From the ARIA Platform foundation to the ARIA Hermes application, we provide the infrastructure that makes AI governable, auditable, and safe to deploy so that warfighters, analysts, operators, and decision-makers can leverage AI with confidence.

We believe that AI accountability shouldn't be an afterthought. It should be the foundation. ARIA enforces policy, keeps an immutable audit trail
