Senior Software Engineer (Backend)

XyloPlan uses science and fire behavior modeling to help communities adapt to wildfire risk. The company is hiring a Senior Software Engineer to build and operate the cloud platform behind its simulation products, with responsibilities spanning backend APIs, simulation job orchestration, observability, security, and customer-facing access to risk data.

Responsibilities:

• Design, build, and maintain backend APIs and services that serve simulation inputs, jobs, and results
• Build the services that power customer-facing front-ends and design customer-exposed APIs with secure, multi-tenant access controls
• Orchestrate compute-heavy simulation processing on GCP (Cloud Run, GKE, Batch, Pub/Sub, Cloud Storage)
• Build logging, monitoring, and observability so simulation pipelines are debuggable and dependable at scale
• Own platform security: authentication, authorization, tenant isolation, secrets management, and data protection for sensitive customer datasets
• Develop CI/CD, infrastructure-as-code, and deployment automation (Terraform, Cloud Build)
• Optimize cost and performance of large batch processing workloads
• Collaborate with the geospatial and simulation teams to productionize their models and pipelines
• Set engineering standards and mentor engineers as the team scales, and contribute to core technical architecture decisions

Requirements:

• REQUIRED QUALIFICATIONS

• 7+ years of professional software engineering experience building and operating production backend systems

• Strong proficiency in Python for backend services and data processing

• 3+ years of hands-on experience with Google Cloud Platform

• Proven experience designing and shipping customer-facing or externally-exposed APIs (REST, gRPC, or GraphQL)

• Experience implementing authentication, authorization, and multi-tenant access controls for customer-facing systems

• Experience with containerization and orchestration (Docker, Kubernetes)

• Strong grounding in application and cloud security best practices

• Experience with observability tooling (logging, metrics, tracing)

• PREFERRED QUALIFICATIONS

• Experience building developer-facing API products, including authentication schemes, rate limiting, versioning, and documentation

• Experience orchestrating large batch or scientific computing workloads

• Experience with infrastructure-as-code (Terraform) and CI/CD pipelines

• Experience handling sensitive or regulated customer data (insurance, financial, or geospatial)

• Experience in an early-stage startup environment

• Exposure to geospatial data, simulation pipelines, or high-performance computing

• Fullstack experience
