Note: The job is a remote job and is open to candidates in USA. Onebrief builds collaboration and AI-powered workflow software for military planning and operational coordination. They are seeking a Senior Software Engineer to help design, build, and operate the systems that power their platform.
Responsibilities
- Design, build, and maintain systems across the stack, from frontend interfaces and APIs to backend services, databases, and infrastructure
- Rotate across squads as priorities shift, bringing your expertise to wherever it creates the most leverage, and ramping quickly in unfamiliar domains
- Evolve and optimize core systems including data models, authentication flows, API layers, and client-side architecture
- Diagnose and resolve performance, scalability, reliability, and security issues in production
- Collaborate on architecture and long-term strategy across platform, infrastructure, and product dimensions
- Implement and refine monitoring, alerting, observability, and auditing across systems
- Use AI-assisted development tools to accelerate implementation, testing, and code quality — and help establish team norms for doing so effectively
- Balance long-term engineering quality with pragmatic, high-velocity delivery
Skills
- 6+ years of experience in software engineering
- Equivalent practical experience valued equally to a formal degree
- Fluency across the stack. Comfortable working in frontend, backend, and infrastructure as the problem demands
- Strong understanding of distributed systems, API design (REST, GraphQL, gRPC), and data modeling
- Hands-on experience with containerization and cloud infrastructure (Docker, Kubernetes, AWS/GCP/Azure)
- Comfort operating in a fluid squad model, able to context-switch, ramp fast on new domains, and contribute without needing long warm-up time
- Active use of AI coding tools (e.g., Claude Code, Cursor, Copilot) to accelerate development. We expect engineers to treat AI as a force multiplier, not an afterthought
- Strong communication skills and the ability to clearly articulate technical trade-offs
- Track record of ownership and delivering complex projects in a fast-paced environment
- Experience with observability stacks (logging, metrics, tracing) and incident response
- Background in mission-critical or high-compliance domains (SOC2, FedRAMP, HIPAA, or DoD)
- Experience with event-driven architectures (Kafka, Pub/Sub, microservices)
- Prior experience driving architecture and system design decisions for complex, high-scale systems
- Some familiarity with authentication protocols (OIDC, OAuth 2.0, SAML) or access control patterns
