Software Engineer - Software Infrastructure (Cybersecurity)

Secure Infrastructure Engineering: Design, harden, and defend containerized application infrastructure across small form factor edge compute and cloud environments. Lead threat modeling, vulnerability management, and security reviews, and evaluate and adopt new tools that maximize system security and reliability while protecting developer velocity.

Provisioning and Configuration Management: Build and maintain automated, reproducible provisioning and installation frameworks (Ansible, Chef, etc.) that take hardware and cloud hosts from bare metal to a hardened, mission-ready baseline, including in air-gapped and disconnected environments.

Secrets Management: Own the lifecycle of secrets, keys, and certificates across the fleet, including issuance, distribution, rotation, and revocation, for systems that must operate with intermittent or no connectivity.

Constrained and Disconnected Environments: Optimize resource usage and harden against denied or degraded network conditions to serve both mobile and web based clients.

Fulfill Department of Defense (DoD) and Intelligence Community (IC) Requirements: Understand, implement, and document the security controls needed to meet the software accreditation and certification standards set forth by the United States DoD and IC.

Minimum of 8-10 years of experience building, securing, and operating software infrastructure at the edge, on premises, or in the cloud.

Strong foundation in cybersecurity, including system and network hardening, threat modeling, vulnerability management, and incident response.

Deep understanding of containerization technologies, with a focus on Docker and Docker Compose, including image building and hardening, container networking and storage, runtime isolation (namespaces, cgroups, seccomp, capabilities, rootless containers), and securing images and registries.

Hands-on experience with provisioning and configuration management frameworks (Ansible, Chef, Puppet, SaltStack, etc.) and Infrastructure-as-Code tools (Terraform, OpenTofu, etc.).

Experience with secrets management and PKI (HashiCorp Vault, OpenBao, AWS KMS, SOPS, TPM or HSM backed keys, etc.).

Deep proficiency with Linux administration and security (SELinux, AppArmor, firewalls, auditing, disk encryption).

Willing to work extended hours for mission critical deadlines.

Bachelor’s degree in Computer Science, Computer Engineering, Cybersecurity, or a related technical field, or equivalent relevant experience.

Experience configuring, building, and hardening custom Linux kernels.

Experience building and maintaining board support packages (BSPs) for embedded or small form factor hardware (L4T, Yocto, Buildroot, U-Boot, etc.), including secure and measured boot.

Familiarity with DoD security frameworks and accreditation processes (RMF, DISA STIGs, NIST SP 800-53, FedRAMP, Impact Level (IL) 4-6).

Expertise with government cloud platforms (AWS GovCloud, Azure Government Cloud).

Proficiency with server and embedded Linux distributions (Ubuntu, NixOS, RHEL).

Familiarity with container orchestration platforms such as Kubernetes (K3s, Rancher RKE2, etc.).

Experience securing CI/CD pipelines and the software supply chain (SBOMs, artifact signing, reproducible builds).

Security certifications such as CompTIA Security+, CISSP, or OSCP.

Active Secret or TS/SCI security clearance.

Competitive salary, stock options and benefits, including health, vision and dental.

401K enrollment at 90 days.

Unlimited PTO plus most Federal Holidays observed.

High levels of responsibility and autonomy.

Professional growth and development opportunities.
