Software Engineer; Tactical Networks - CANES | Active Secret clearance

Overview

Transform code into mission capability as a Senior Software Engineer with GDIT. You’ll design, develop, integrate, and sustain software that powers Consolidated Afloat Networks and Enterprise Services (CANES) and related Navy tactical network capabilities with NIWC Pacific (Codes 55131/55132/55133) in support of PMW-160 Tactical Networks—spanning ashore, afloat, subsurface, airborne, mobile, and joint environments.

• Design and develop mission applications and services aligned to CANES functional specifications; deliver microservices, RESTful APIs, and data pipelines supporting C4
  
  ISR workflows.
• Lead application integration (AI) activities: feasibility assessments, interface definition, dependency analysis, and produce HACSIM/AI documentation for fleet implementation.
• Build secure, containerized solutions (Docker/Kubernetes/Helm) for virtualized data centers; implement CI/CD (Git Lab/Jenkins), IaC/automation (Ansible/Terraform), and package/version governance.
• Author and execute the Software Development Plan (SDP) per IEEE/EIA 12207; contribute to SEPs/EIPs and DoDAF-aligned architecture views across enterprise/tactical/system levels.
• Engineer to Navy cybersecurity requirements: apply DISA SRGs/STIGs, SAST/DAST (Sonar Qube/Fortify/Checkmarx), artifact hardening, logging, and RMF evidence to preserve ATO conditions.
• Develop test plans/procedures; support Developmental Test & Evaluation (DT&E), lab events, SOVTs, and TRRs; perform defect triage, root-cause analysis, and MS/FRACAS reporting.
• Produce engineering documentation (design specs, ICDs, sequence/flow, as-built software baselines, release notes) and contribute to CM (CMPro), CCB/PTRB change workflows, and BoMs.
• Optimize performance/reliability (profiling, concurrency models, caching, message queues), observability (metrics/tracing/logs), and resilience (retry/backoff/circuit-breaker patterns).
• Collaborate with NIWC Pacific, PEO C4I/PMW-160, Fleet stakeholders, and cybersecurity teams; mentor junior developers and champion Dev Sec Ops  and secure coding best practices.

• Security Clearance:
  Active Secret clearance.
• 10+ years software engineering for enterprise or tactical systems using Java and/or Python (C++/Go a plus), including API design, messaging, and data integration.
• 3+ years delivering containerized solutions with CI/CD (Git Lab/Jenkins), Git, and automated testing (unit/integration/e2e).
• Hands-on with Kubernetes or equivalent orchestration in virtualized environments (vSphere/vCenter).
• DoD/Navy development experience applying DISA STIGs, secure coding, and contributing RMF artifacts to ATO packages.
• Authoring SDPs/ICDs/design docs; executing DT&E/SOVT test events and documenting results.
• Skills/Tools: Spring Boot/Quarkus or similar;
  Flask/FastAPI/Django; gRPC/REST; JSON/Protobuf; SQL/No
  
  SQL (Postgre
  
  SQL/Elastic/Redis); message buses (Kafka/Rabbit
  
  MQ);
  Wireshark/Postman;
  Jira/Confluence.
• Certifications: DoD 8570/8140 IAT-II baseline (e.g., Security+ CE) or ability to obtain within 60 days of start.
• Education: BS/BA in Computer Science, Software Engineering, Information Systems, or related field (equivalent experience may substitute per GDIT policy).
• Work Location: Onsite NIWC Pacific, San Diego, CA (labs/shipyards/fleet concentration areas). Limited CONUS/OCONUS travel as tasking requires; ability to work in classified labs and onboard ships/submarines/airborne ground sites.
• Position Availability: Position is pending final contract award.
• US Citizenship Required

• Prior NIWC Pacific/PMW-160/CANES support; familiarity with ADNS, GPON, cross-domain/guard interfaces, and multi-enclave development.
• CSSLP, AWS/Azure Associate/Pro, RHCSA/RHCE, CKA/CKAD, or VCP-DCV/NV.
• Experience with DoDAF modeling, NESI/DISR alignment, and performance at scale (low-bandwidth/disconnected/edge).
• SAST/DAST pipeline integration, STIG automation (Ansible), SBOM generation (Cyclone
  
  DX/Syft/Grype), and supply-chain security (SLSA/SCVS).
• Real-time/streaming analytics (Kafka Streams/Flink/Spark), geospatial, or time-series processing for mission applications.
