About usOne team. Global challenges. Infinite opportunities. At Viasat, we're on a mission to deliver connections with the capacity to change the world. For more than 35 years, Viasat has helped shape how consumers, businesses, governments and militaries around the globe communicate. We're looking for people who think big, act fearlessly, and create an inclusive environment that drives positive impact to join our team.
What you'll doThe Integrated Solutions Business Unit is hiring a Lead Systems Engineer to serve as the technical center of gravity for our Tactical Mission Fabric (TMF) program.
This is a hands-on systems engineering leadership role, not a pure management seat and not a requirements-analysis-only role. You will personally lead the integration of cloud, network, security, and cryptographic subsystems into a unified, accredited platform; author the IaC that deploys it; and own integration outcomes end to end while setting the technical bar for the engineers around you. We're looking for a senior engineer ready for a formal leadership step: someone who has already led through technical influence and cross-functional ownership, and who is ready to formally lead a team for the first time, or who has begun leading and wants broader scope.
The day-to-day- End-to-End Platform Integration: Integrate AWS GovCloud multi-account infrastructure, SD-WAN overlay, MPLS underlay, NGFW boundary security, and cryptographic solutions into a single accredited I/NaaS. Own the seams between subsystems.
- IaC-First Engineering: Author Terraform modules and Ansible AWX playbooks for all TMF deployments. Every change goes through GitLab CI/CD with peer review.
- AWS Architecture at Scale: Design and operate multi-account architectures including Organizations, Transit Gateway, Direct Connect Gateway, PrivateLink, and VPC topologies supporting multi-tenant isolation.
- SD-WAN and Network Integration: Own design and integration of the SD-WAN overlay, BGP routing (including EVPN/VXLAN), IPsec tunnel engineering, and enterprise firewall HA pairs at every ingress and egress zone.
- Requirements, Architecture, V&V: Run the V-Model lifecycle on TMF deliverables (SRR, PDR, CDR), maintain the RTM, define subsystem interfaces, and execute verification and validation against mission needs.
- Security and Compliance Engineering: Map configurations to NIST 800-53 Rev 5 and 800-171, engineer telemetry into the SIEM, apply STIG and CIS hardening, and produce SSP artifacts that hold up to FedRAMP and CMMC Level 2 scrutiny.
- Integration Risk Management: Identify cross-domain failure points early, develop mitigation plans, and make trade-off calls visible to engineering and program leadership.
- Set and enforce standards for SE deliverables, integration quality, and IaC discipline across the TMF team and the broader Integrated Solutions portfolio.
- Mentor systems engineers across experience levels; run technical and code reviews that raise the team's bar.
- Translate between network engineering, cloud engineering, security, program management, and customer stakeholders.
- Own SE and platform outcomes across multiple tenants and programs, not only the ones you personally execute.
- Grow into formal team leadership: partner with the Director on direction, hiring, and resource allocation, with a clear path to direct people management.
What you'll need- Hands-on Terraform module authoring with disciplined GitOps practice at production scale
- AWS hands-on experience: VPC, IAM, security groups, EC2, S3, and multi-account patterns
- Deep IP networking expertise: TCP/IP, BGP (including EVPN), OSPF, IPsec, and SD-WAN overlay design
- Hands-on V-Model lifecycle experience on government contract deliverables (SRR, PDR, CDR)
- Demonstrated leadership impact as an individual contributor: standing up a technical capability, mentoring engineers, leading a technical workstream, or sustained cross-functional technical leadership
- Readiness to step into a formal leadership billet with a path to direct people management
- 8+ years systems engineering or systems integration in defense, federal, SATCOM, or telecom environments
- Bachelor's in EE, CS, Telecom, or related technical field
- ship required
- Active DoD Secret clearance required.
- Ability to travel up to 10%
