Job Description & How to Apply Below
Position: DevSecOps Engineer with Security Clearance
Dev Sec Ops  Engineer Fully Remote The Dev Sec Ops  Engineer serves as a senior technical lead enabling secure, rapid development and execution of JOMIS Dev Sec Ops  pipelines for operational-medicine capabilities, including MedCOP, Operational Medicine Care Delivery Platform (OpMed CDP), MHS GENESIS-Theater (MHSG-T), BATDOK-J, and related theater blood and operational data services. The role owns end-to-end Dev Sec Ops  practices across cloud and hybrid environments (e.g., Cloud One), embedding security in CI/CD, automating infrastructure, and ensuring compliance with DoD/DHA standards.

The engineer leads a team of Dev Ops/Platform engineers, partners with cybersecurity and product teams, and aligns delivery with JOMIS test and fielding cycles to sustain resilient, interoperable solutions for connected, intermittent, and disconnected operations.

JOB RESPONSIBILITIES:

* Lead design, implementation, and sustainment of secure CI/CD/CT pipelines (e.g., Git Lab, Jenkins) with integrated SAST/DAST, SBOM/dependency scanning, image signing, and policy gates.
* Lead and mentor Dev Ops/Platform engineers; establish engineering standards, code reviews, runbooks/SOPs, and on-call rotations.
* Implement Infrastructure-as-Code / Configuration-as-Code (Terraform, Terragrunt, Ansible) for repeatable environment provisioning, drift control, and compliant baselines.
* Engineer and operate container platforms (Docker/Kubernetes/Open Shift) with registry controls, runtime protection, and automated compliance checks.
* Integrate and operate observability (logging, metrics, tracing) and alerting to meet SLOs/SLIs for MedCOP, OpMed CDP, MHSG-T, and BATDOK-J releases and test events.
* Embed Zero Trust and least-privilege patterns in pipelines and runtime (secrets management, identity-aware access, signed artifacts, network segmentation).
* Align Dev Sec Ops  delivery to JOMIS test and fielding activities (lab, interoperability/regression, JITC/OT&E events), supporting rapid fixes and secure hotfix pipelines.
* Partner with product and vendor teams to onboard applications, modernize legacy integration patterns, and improve performance/reliability in austere and low-bandwidth environments.
* Support RMF/ATO sustainment by generating pipeline evidence (build attestations, SBOMs, scan reports), maintaining SSP/POA&M artifacts, and meeting DISA STIG and SRG controls.
* Drive cost, capacity, and resilience improvements (right-sizing, autoscaling, blue/green/canary, chaos testing) and track error budgets tied to mission KPIs.
* Coordinate with DHA J-6, enterprise service providers, and program vendors to ensure interoperability, cybersecurity, and enterprise compliance.

JOB REQUIREMENTS:

* Education:

Bachelor's degree in computer science, Software Engineering, Information Systems, Cybersecurity, or a related technical field (Master's preferred).

* Experience:

Minimum 7 years of hands-on Dev Ops/Cloud/Platform engineering, including team leadership delivering production pipelines and platforms.
* Expert with CI/CD (Git Lab/Jenkins), IaC/CaC (Terraform, Terragrunt, Ansible), and containers/orchestration (Docker, Kubernetes/Open Shift).
* Strong scripting/automation in Python and Bash (Poetry or similar packaging preferred).
* Experience implementing secure software supply-chain practices (artifact signing, SBOM, provenance/attestation, policy-as-code).
* Proven delivery in cloud/hybrid environments (AWS / Cloud One), including IAM, networking, and cost/performance optimization.
* Working knowledge of DoD/DHA cybersecurity (DISA STIGs, SRG, NIST SP 800-53, RMF/ATO, Zero Trust).
* Ability to collaborate across product, cybersecurity, test, and infrastructure teams and to communicate clearly with technical and non-technical stakeholders. KEY

COMPETENCIES:

* Dev Sec Ops  at scale: secure SDLC, pipeline policy gates, automated compliance evidence, and release orchestration for multi-app portfolios.
* Operational-medicine context: delivery and sustainment for MedCOP, OpMed CDP, MHSG-T, BATDOK-J, and theater solutions supporting connected/intermittent/disconnected use.
* Software-factory & platform engineering:
Git Ops, Git Lab/Jenkins runners, artifact registries, environment promotion, golden AMI/container baselines.
* Observability & reliability: SLO design, telemetry pipelines, performance tuning, fault injection/chaos testing, and incident/post-incident management.
* Interoperability readiness: data-exchange support, interface hardening, pre-deployment lab/regression testing aligned to JOMIS schedules.
* Leadership: mentoring engineers, setting standards, managing priorities, and driving continuous improvement across tools and processes.

CERTIFICATIONS:

* Required:

CompTIA Security (or equivalent DoD 8140 IAT II baseline).
* Recommended: AWS Certified Solutions Architect - Associate (or higher) or AWS Dev Ops Engineer - Professional;
Hashi Corp Terraform Associate; CKA/CKS (Kubernetes).
* Preferred: SAFe/Agile (e.g., SAFe POPM or SAFe SA), GIAC…
