Demonstrate ability to leverage AI coding assistants effectively in day-to-day software development • Experience with FastAPI, Starlette, or similar Python ASGI frameworks • Experience with Pydantic and its larger ecosystem • Experience with PostgreSQL, PostGIS, and/or geospatial or time-series data • Experience with AWS services such as S3, RDS, EventBridge, EKS • Experience with workflow orchestration systems such as Prefect, Temporal, Airflow, or similar • Experience with observability tooling built on OpenTelemetry • Experience in energy systems, infrastructure software, climate tech, or other complex technical domains • Experience integrating LLM-based features into production applications

Responsibilities

• Build and evolve the backend-for-frontend / application API layer that powers GridCARE’s web application • Own product features end to end, from understanding the user and domain problem to shipping polished, production-ready software • Design and implement HTTP APIs, webhook flows, and status/result delivery patterns for uploads, jobs, and other user-facing workflows • Define typed request/response models and clear contracts between the frontend, API layer, and backend execution systems • Implement backend services in Python that integrate with Auth0, datastores including RDS and S3, and batch-job orchestration systems • Contribute to the product surface in a modern TypeScript SPA when needed, and help establish maintainable frontend patterns • Partner closely with domain experts to turn analytical and batch workflows into usable product features • Collaborate with platform and SRE teammates on observability, deployability, reliability, and production operations • Help replace prototype-era systems with typed, testable, production-grade software • Contribute to architecture decisions, engineering standards, and development culture as the team grows

Benefits

• Work on a problem that directly affects the speed of deploying new AI and energy infrastructure • Help build a product from the ground up alongside domain experts and experienced infrastructure teammates • Own meaningful technical scope in a small, high-trust team • Competitive salary, equity, and benefits • Hybrid collaboration in Redwood City with flexibility for remote work • Our Philosophy • Our Philosophy • We believe small teams of strong engineers can solve important, real-world infrastructure problems. • We value clear thinking, strong ownership, pragmatic execution, and systems that hold up in production. We move quickly, but we care about correctness, reliability, and building software that customers can trust. • If you’re excited about building backend-heavy product software at the intersection of energy, infrastructure, and modern SaaS, we’d love to talk.
