About The Role

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.

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.

US Citizenship is mandatory due to federal access

7+ years of experience in Infrastructure or Platform Engineering, SRE, or DevOps with a focus on data-intensive systems. Deep Data Systems Expertise: Proven track record of supporting high-scale stateful infrastructure in production.

Key Responsibilities

Infrastructure Modernization Scale: Lead and contribute to architectural initiatives designed to improve the scalability and cost-efficiency of our Federal environment. You will identify bottlenecks and drive improvements in our database and compute layers to support large-scale customer growth. Operational Excellence Incident Resolution: Serve as the senior technical escalation point for Data Infrastructure issues in FedRAMP.

You will leverage direct environment access to investigate complex incidents, analyze root causes, and drastically reduce resolution time for production issues. You will create automations and drive initiatives to improve the infrastructure's self-healing and self-service capabilities. Resilience Business Continuity: Collaborate with the Data Infrastructure team to enhance and validate Disaster Recovery (DR) strategies.

You will help ensure our Federal environment meets strict availability standards and is prepared for regional failover scenarios. Database Streaming Reliability: Ensure the health and performance of core stateful systems (PostgreSQL, MongoDB, Kafka) under strict compliance constraints. You will be responsible for deep-dive troubleshooting and tuning, not just deployment.

Security Compliance: 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). R D Liaison: Act as the technical representative of the Data Infrastructure R D group within the Federal environment. You will provide feedback to the core team on Federal-specific challenges and ensure that new R D features are successfully landed and operationalized in FedRAMP.
