Responsibilities
Lead the redesign of our core architecture platform backend, defining clear service boundaries and APIs in Python so simulation, data, and UI layers stay decoupled and manageable
Build resilient Python-first pipelines that move jobs, configs, and artifacts between on-prem/HPC environments and cloud services, emphasizing reproducibility and debuggability
Own database and caching strategy-schema/version design, indexing, migrations, and Redis/Valkey-backed state layers-so long-lived experiments evolve without breaking downstream users
Stand up and operate Terraform-managed AWS infrastructure (EC2/EKS/S3/IAM, etc.), integrate authN/Z (OAuth2/OIDC/SSO), and embed logging/metrics/tracing for operational clarity
Deliver internal tooling (CLIs, REST/gRPC endpoints, Python SDKs) and documentation that let researchers and engineers launch, observe, and compare simulations without digging through multiple repos
Raise the engineering bar: typed Python, thorough testing, CI/CD gates, and mentoring peers on platform design, performance tuning, and modular system composition
Qualification
Required
8+ years building backend/platform systems in Python, including leading significant re-architecture efforts
Expert-level Python (async, packaging, profiling) with production experience in FastAPI/Flask/Django and typed interface patterns (pydantic/mypy)
Demonstrated success shipping reproducible pipelines or workflow engines that span HPC/Slurm-style schedulers and cloud infrastructure, including task orchestration and artifact provenance
Deep AWS + Terraform experience across multi-environment deployments; comfortable wiring auth layers and managing secrets/service identities
Strong database and state-system background (Postgres/MySQL/Mongo + Redis/Valkey), covering schema design, migrations, query tuning, and cache/state orchestration
History of designing and maintaining internal APIs/SDKs (REST/gRPC/Python clients) with clear contracts, versioning, and documentation practices
Hands-on with CI/CD, static analysis, typed Python tooling, observability stacks (Prometheus/Grafana/OpenTelemetry, profilers) to keep services reliable and diagnosable
Bachelor's Degree or higher in Computer Science, Engineering
Preferred
experience building platforms that serve research-heavy or experiment-driven teams, where complex workflows and long-running jobs demand clear interfaces and repeatable execution
