About The Position

We are seeking a Senior Software Engineer to join our team. In this role, you will be responsible for designing, building, and maintaining backend APIs and services that serve simulation inputs, jobs, and results. You will also build the services that power customer-facing front-ends and design customer-exposed APIs with secure, multi-tenant access controls. Additionally, you will orchestrate compute-heavy simulation processing on GCP, build logging, monitoring, and observability for debuggable and dependable simulation pipelines at scale, and own platform security including authentication, authorization, tenant isolation, secrets management, and data protection. You will develop CI/CD, infrastructure-as-code, and deployment automation, optimize cost and performance of large batch processing workloads, and collaborate with the geospatial and simulation teams to productionize their models and pipelines. You will also set engineering standards, mentor engineers, and contribute to core technical architecture decisions.

Requirements

• 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)

Nice To Haves

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

• 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

Responsibilities

• 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
