## Job description

About Us: Quartermaster builds secure, mission-critical systems where reliability, observability, and security are non-negotiable. We are hiring a Senior Internal Infrastructure Engineer to help design and operate internal platform infrastructure across AWS and Azure. You will partner with engineering and security to improve GitOps delivery, infrastructure as code, Kubernetes operations, observability, edge networking, and support for IoT, streaming, and ML workloads in remote sensor systems.

What You Will Do:

- Architect and operate secure, multi-environment infrastructure across AWS, AWS Gov, Azure, and Azure Gov.
- Build GitOps pipelines and reusable OpenTofu (or similar) (Terraform-compatible) modules with strong CI validation.
- Operate Kubernetes platforms (including Helm) and improve reliability through SLOs, postmortems, and automation.
- Build observability with Grafana and modern telemetry (metrics, logs, traces, and alerting).
- Operate edge networking plus IoT and streaming pipelines (including AWS IoT and Kinesis) for remote sensor data.
- Support secure ML workloads and strengthen platform security across identity, secrets, policy, hardening, and compliance controls.

Cultural and Operating Principles

- Build systems that produce work: prioritize durable platforms and workflows over one-off heroics.
- Move fast: don't produce perfect solutions first, get on the board and then optimize
- AI-augmented execution: actively use and improve AI-assisted workflows for infrastructure design, operations, troubleshooting, and developer productivity.
- Safe agency: create clear guardrails, defaults, and feedback loops so engineers can move quickly with confidence.
- Empower engineering users: build self-service platform capabilities, paved roads, and documentation that reduce friction and accelerate delivery.

Preferred Qualifications:

- 7+ years in infrastructure/platform/SRE roles with direct ownership of production systems.
- Deep Azure experience, including high-security and regulated environments (Azure Government strongly preferred).
- Practical AWS experience, especially with IoT services, Kinesis, and event/stream-processing architectures.
- Expert-level Kubernetes operations experience and strong Helm experience.
- Strong GitOps background and a track record improving delivery safety and speed.
- Strong infrastructure-as-code expertise with OpenTofu/Terraform and policy-oriented workflows.
- Strong experience using observability platforms w/ Grafana (preferred) and modern telemetry practices.
- Experience with edge networking, distributed edge deployments, and remote sensor telemetry pipelines.
- Experience supporting ML/AI workloads and secure data processing at cloud and edge.
- Demonstrated security depth in IAM, network segmentation, zero trust, secrets management, encryption, and policy as code.
- Clear evidence of functionality-first thinking and comfort with AI-augmented engineering workflows.

## Nice to Have

- Experience with FedRAMP, NIST 800-53, CMMC, IL4/IL5, or similar frameworks.
- Experience with service meshes, policy engines (for example, OPA/Gatekeeper), workload identity, and software supply chain controls (for example, SBOM practices).
- Experience with multi-cluster or hybrid cloud/edge Kubernetes topologies.

Success Metrics Faster lead time, lower change failure rate, and improved MTTR. Secure, auditable infrastructure changes through GitOps and infrastructure as code. Reliable operation of IoT, streaming, edge, remote sensor, and ML workloads.

## About Quartermaster

## Company Overview
- **One-liner**: Quartermaster builds a real-time, distributed maritime awareness network by equipping vessels with AI-powered sensor packages (SmartMast) and an analytics platform.
- **Entity Type**: Private (Series A)
- **Headquarters**: Arlington, Virginia, United States
- **Founded**: 2023
- **Founders**: Neil Sobin (CEO)

## Core Business
- **Primary industry**: Maritime intelligence, defense technology, AI/robotics, ocean sensing
- **Target customers**: Governments (navies, coast guards), commercial shipping operators, insurers, and maritime researchers (B2G, B2B)
- **Mission**: “Connect every vessel on the water to create a comprehensive, real-time picture of our oceans, unlocking critical data insights that underpin a prosperous global maritime ecosystem.” [quartermaster.us](https://www.quartermaster.us/about)

## Products & Services
- **SmartMast**: A weather-hardened hardware package (cameras, radios, sensors) mounted on a ship’s mast that continuously collects and relays maritime data. Combined with an AI analytics platform, it provides real-time vessel identification, anomaly detection, and environmental monitoring. [techcrunch.com](https://techcrunch.com/2026/05/20/this-startup-raised-43m-to-build-a-hive-mind-for-ships/)
- **Quartermaster Analytics Platform**: Cloud-based software that ingests SmartMast data and applies computer vision and machine learning to generate actionable intelligence for fleet operators, insurers, and government agencies.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: $43 million in Series A funding (announced May 20, 2026) [techcrunch.com](https://techcrunch.com/2026/05/20/this-startup-raised-43m-to-build-a-hive-mind-for-ships/)
- **Notable Investors/Partners**: Co-led by First Round Capital and Quiet Capital, with participation from TMV, Steel Atlas, BoxGroup, Operator Partners, Shorewind Capital, and David (surname not specified). Key hires from Anduril (Steve Ribaudo as CGO) and Scale AI (Matt Beck as COO). [quartermaster.us](https://www.quartermaster.us/about) | [linkedin.com](https://www.linkedin.com/company/quartermasterai)
- **Growth Signals**:
  - Headcount grew 625% year-over-year to 40 employees (as of mid-2026). [linkedin.com](https://www.linkedin.com/company/quartermasterai)
  - Over 600 ships equipped with SmartMast, covering 10 million square miles of ocean. [techcrunch.com](https://techcrunch.com/2026/05/20/this-startup-raised-43m-to-build-a-hive-mind-for-ships/)
  - Assisted in “over 20 rescues of mariners at sea.” [techcrunch.com](https://techcrunch.com/2026/05/20/this-startup-raised-43m-to-build-a-hive-mind-for-ships/)
  - Operates in 7 countries (Panama, Colombia, South Korea, UAE, Brazil, Taiwan, United States). [linkedin.com](https://www.linkedin.com/company/quartermasterai)

## Competitive Advantages
- **Proprietary hardware edge**: SmartMast is far more advanced than the standard AIS (Automatic Identification System), which is opt-in and easily spoofed. Quartermaster’s sensors provide persistent, verified, real-time data that is less susceptible to fraud. [techcrunch.com](https://techcrunch.com/2026/05/20/this-startup-raised-43m-to-build-a-hive-mind-for-ships/)
- **Pro-mariner incentive model**: Rather than selling sensors to fleet operators (a tough sell in a low-margin industry), Quartermaster creates value for mariners (e.g., rescue support, safety data) to encourage voluntary adoption, locking in network effects. [techcrunch.com](https://techcrunch.com/2026/05/20/this-startup-raised-43m-to-build-a-hive-mind-for-ships/)
- **First-mover in distributed ocean sensing**: No other company has deployed a real-time, AI-powered sensor constellation at this scale, giving Quartermaster a data moat and early relationships with governments and commercial fleets.

## Strategic Focus
