Senior Data Infrastructure Engineer, Onebrief

• You are a systems-minded engineer who thrives at the intersection of data, distributed systems, and cloud architecture.
• You think holistically, understanding how data flows, how systems interact, and how to design for long-term scalability, and integrity
• You are hands-on, curious, and continuously learning. You enjoy diving into new technologies, building modular architectures (aligned with MOSA principles), and delivering solutions that are elegant, observable, and secure.
• You are comfortable in multiple settings, from writing services to tuning infrastructure, and take pride in building platforms that let others move faster and safer
• 5+ years of software engineering experience, including hands-on work with distributed or data-intensive systems
• Proven experience running production workloads using Kafka, PostgreSQL, and S3, ideally with CDC, ETL/ELT, or streaming data pipelines
• Proficiency in Java and JavaScript/TypeScript, with experience in both backend and front-end systems
• Strong grasp of distributed systems principles, including replication, partitioning, idempotency, and consistency trade-offs
• Experience deploying and monitoring workloads on AWS or Azure using Infrastructure as Code (Terraform, CloudFormation, or Bicep)
• Understanding of data governance concepts, such as lineage, schema evolution, and access-control frameworks
• Familiarity with MOSA, modular, or microservices architectures emphasizing interoperability and reusability
• Systems thinker and continuous learner who bridges software, data, and infrastructure domains

Desirable

• We are looking for a Senior Data Infrastructure Engineer (Distributed Data & Cloud Platforms) to design, build, and operate distributed, event-driven systems that move, transform, and secure information from the edge to the cloud
• You will work across infrastructure, data, and application layers to deliver reliable, real-time data pipelines and services that underpin Onebrief’s mission. The systems you design will enable our customers, military staffs operating in complex, high-stakes environments, to make faster and smarter decisions with confidence
• This role blends software craftsmanship, distributed systems engineering, and a deep respect for reliability, observability, and governance
• Design and implement event-driven, distributed architectures using Kafka, PostgreSQL, S3, and Lakehouse technologies (e.g., Delta Lake, Iceberg)
• Develop and operate end-to-end services in Java and TypeScript (React/Node) that interact with data pipelines, APIs, and dashboards
• Engineer for reliability and observability on fault-tolerant, eventually consistent systems that perform across multi-cloud and hybrid environments
• Model, govern, and secure data using metadata, lineage, and access-control principles that support compliance and auditability
• Implement instrumentation, performance analytics, and cost optimization across systems
• Collaborate across Infrastructure, Product, and Engineering teams to ensure architectural cohesion and MOSA-aligned design
• Continuously learn, evaluate, and apply emerging technologies in distributed data, governance, and DevSecOps
