Senior Staff Data Infrastructure Engineer

Armis Security•New York, NY

14h•$200,000 - $220,000•Remote

About The Position

We are looking for a Senior Staff Engineer to join our Data Infrastructure R&D Group as a dedicated expert for our rapidly growing Federal business sector. In this unique role, you will be an integral member of the core Data Infrastructure engineering team. While you will be physically located in the US to meet federal access requirements, you will operate as an extension of the R&D group, acting as the critical bridge between the Data Infrastructure group and the US-based Federal Operations team, owning the entire data infrastructure in FedRAMP environments. You will combine deep infrastructure engineering with operational excellence—driving architectural improvements, optimizing cloud efficiency, and handling complex production investigations that require high-level clearance and access. If you are a builder who loves solving complex distributed system problems and wants to play a central role in a massive-scale secure environment, this is your opportunity.

Requirements

US Citizenship is mandatory due to federal access requirements.
7+ years of experience in Infrastructure or Platform Engineering, SRE, or DevOps with a focus on data-intensive systems.
Proven track record of supporting high-scale stateful infrastructure in production.
In-depth, hands-on understanding of at least one major relational database (e.g., PostgreSQL), one streaming platform (e.g., Kafka), and open-lakehouse technologies (e.g, Spark, EMR, Hive, Trino).
Strong hands-on experience debugging production issues in Linux environments and managing AWS infrastructure.
Comfortable not just deploying to K8s, but debugging it—understanding networking, resource scheduling, and complex operator patterns.
Proficiency with Terraform, Helm, or similar tools to manage infrastructure reproducibly.
Excellent written and verbal communication skills. You need to be able to explain complex technical issues to remote R&D teams and mentor local Ops teams.

Nice To Haves

Experience with FedRAMP, IL5, or DoD compliance frameworks.
Experience with Service Mesh technologies (e.g., Istio) and secure networking.
Familiarity with Big Data frameworks or NoSQL databases.
Experience working in a distributed global engineering organization.
GovCloud experience is a plus, but not required.

Responsibilities

Lead and contribute to architectural initiatives designed to improve the scalability and cost-efficiency of our Federal environment.
Identify bottlenecks and drive improvements in our database and compute layers to support large-scale customer growth.
Serve as the senior technical escalation point for Data Infrastructure issues in FedRAMP.
Leverage direct environment access to investigate complex incidents, analyze root causes, and drastically reduce resolution time for production issues.
Create automations and drive initiatives to improve the infrastructure's self-healing and self-service capabilities.
Collaborate with the Data Infrastructure team to enhance and validate Disaster Recovery (DR) strategies.
Help ensure our Federal environment meets strict availability standards and is prepared for regional failover scenarios.
Ensure the health and performance of core stateful systems (PostgreSQL, MongoDB, Kafka) under strict compliance constraints.
Be responsible for deep-dive troubleshooting and tuning, not just deployment.
Partner with security teams to implement necessary controls, including automated certificate management, network policy enforcement (Service Mesh), and regular security patching to maintain our Authority to Operate (ATO).
Act as the technical representative of the Data Infrastructure R&D group within the Federal environment.
Provide feedback to the core team on Federal-specific challenges and ensure that new R&D features are successfully landed and operationalized in FedRAMP.
