Role Overview

The DevOps Engineer is responsible for the design, reliability, and continuous improvement of Lynk’s AWS cloud infrastructure. This role owns the full lifecycle of cloud environments — from infrastructure provisioning and CI/CD pipelines to security, compliance, and operational support. The position operates within a fast-paced, compliance-driven environment and requires both steady operational execution and proactive infrastructure improvement. CMMC Level 2 compliance is non-negotiable in everything you build.

Key Responsibilities

Infrastructure & Terraform

Design, build, and maintain AWS infrastructure using Terraform as the IaC standard across all environments (dev, staging, production)
Manage Terraform modules, state management, remote backends, and workspace strategy
Participate in architecture reviews and drive infrastructure optimization and cost management
Maintain AWS Organizations or multi-account architecture as the environment scales

CI/CD & Automation

Own and evolve CI/CD pipelines (GitLab CI or GitHub Actions) — from code commit to production deployment
Identify and implement automation opportunities to reduce manual operational overhead
Support and maintain deployment workflows for application and platform teams

AWS Platform Operations

Manage core AWS services: EC2, ECS, S3, RDS, Lambda, SQS, SNS, CloudWatch, KMS, IAM, VPC, Route53, CloudFront
Design, deploy, and maintain serverless workloads using AWS Lambda — including function lifecycle management, concurrency, event source mappings, and cold-start optimization
Operate and support AWS Ground Station for satellite communication scheduling, antenna management, and data downlink pipelines
Monitor infrastructure health using Tenable for vulnerability and compliance scanning, CloudWatch for operational metrics, and PagerDuty or equivalent for alerting and incident response

Security & Compliance

Enforce infrastructure security posture aligned with CMMC Level 2 — IAM least privilege, encryption at rest/in transit, secrets management (AWS Secrets Manager, Parameter Store)
Manage team-based IAM access using AWS IAM Identity Center — permission sets, group assignments, account entitlements, and SCIM-based provisioning across the multi-account org
Use Tenable to continuously assess infrastructure for vulnerabilities and maintain CMMC Level 2 compliance evidence
Manage certificate lifecycles, KMS key policies, and privileged access controls
Support audit activities with accurate, current documentation and evidence

Documentation & Cross-Functional Support

Maintain SOPs, runbooks, and architecture diagrams
Collaborate with engineering teams on capacity planning and platform reliability

Required Qualifications

4+ years of DevOps/infrastructure engineering experience in AWS-native environments
Deep hands-on Terraform experience — modules, state management, remote backends, workspace strategy
Proficient with AWS core services: EC2, ECS, S3, RDS, Lambda, SQS/SNS, IAM, VPC, CloudWatch, KMS
Strong Linux/Unix administration and scripting (Bash, Python)
CI/CD pipeline ownership — GitLab CI, GitHub Actions, or Jenkins
Serverless architecture and AWS Lambda — function design, event-driven patterns, IAM execution roles, and observability
Experience with AWS Ground Station or other satellite ground segment infrastructure
AWS IAM Identity Center — permission sets, group-to-account assignments, SCIM provisioning, and SSO integration
Experience operating in CMMC Level 2 or equivalent DoD/regulated compliance environments
Solid understanding of network fundamentals: VPC design, security groups, NACLs, peering, Transit Gateway
Comfortable working asynchronously and remotely without daily check-ins

Preferred Qualifications

AWS certifications (Solutions Architect, DevOps Engineer Professional, or Security Specialty)
Familiarity with Datadog, Grafana, or similar observability stacks
Experience with database platforms: PostgreSQL, Aurora, or DynamoDB
Prior work in defense, federal, or regulated industries (DoD, FedRAMP, CMMC, ITAR)
Experience with AWS Organizations, Control Tower, or multi-account architectures
Infrastructure cost optimization — Reserved Instances, Savings Plans, right-sizing
Experience in a startup or small-team environment where ownership breadth is high
Bachelor’s degree in Computer Science, Engineering, or equivalent practical experience

What “Works Independently” Means Here At Lynk

Independent operation is a core requirement, not a preference.

Specifically, This Means

You receive an objective, not a step-by-step plan. You define the approach.
You triage and prioritize your own backlog with limited daily oversight.
When you hit a blocker, you exhaust reasonable paths before escalating.
You produce documentation and runbooks as a matter of habit, not when asked.
You proactively flag risks, degraded performance, and technical debt before they become incidents.
You deliver on commitments and communicate early when scope or timelines shift.

Benefits

Competitive compensation benchmarked to US market rates
Medical, dental, and vision coverage
Paid Time Off and federal holidays
Opportunity for growth within a fast-moving, mission-driven technology company
