Software Engineer - Member of Technical Staff (Consumption Team)

Generalist Software Engineer building backend Python APIs, marketplace orchestration, billing systems, and developer tooling for an AI GPU compute infrastructure platform. Own features end-to-end across backend, databases, frontend, and cloud integrations in a hybrid Palo Alto/SF role.

About the job

Core Responsibilities

Backend & API

  • Build and maintain backend Python APIs powering reservation, bidding, billing, and usage surfaces — including usage visualization and the billing platform.
  • Write and maintain database migrations, design relational schemas for complex multi-entity models (orders, allocations, grants, quotas), and optimize queries for performance.
  • Own features end-to-end: from design doc through backend API, database migration, feature flag rollout, and monitoring.

Platform & Marketplace

  • Design and implement orchestration primitives for flexible reservations: pause/return credits, reservation extensions, capacity algorithm updates, and the auction model connecting spot and reserved capacity.
  • Contribute to operational maturity — quota systems, financial controls, fraud prevention, and inventory management automation.

Supply Integrations

  • Contribute to supply-side integrations, bringing GCP, Nebius, and OCI resources under Mithril management through the Mithril API.
  • Build tooling to give operators visibility into managed capacity and surface supply constraints early.

Consumption & Developer Tooling

  • Build consumption tooling to help developers make better decisions: reservation calculators, bid modeling, cost dashboards, and CLI extensions.
  • Work across the client frontend to ship customer-facing features including usage graphs, billing views, and reservation management UIs.

Operations

  • Participate in on-call rotations, triage production incidents, and contribute to operational runbooks and automation that reduce toil over time.

Requirements

  • Strong Python backend skills — built and maintained production APIs at real scale.
  • Proven experience with distributed systems; comfortable with messaging systems (RabbitMQ, Kafka) and RPC methods (gRPC, protobuf, tRPC).
  • Fluency with relational databases: schema design, query optimization, and migrations in production environments.
  • Ability to own a feature end-to-end — from design doc through backend API, database migration, feature flag rollout, and monitoring.
  • Strong debugging instincts: calm and systematic when triaging production incidents, with a bias toward durable fixes.
  • Comfortable in small teams where ownership is high and process is lightweight.

Nice to Have

  • Experience with marketplace and billing systems — especially variable-usage, auction-based, or complex reservation models.
  • Familiarity with Kubernetes, AWS infrastructure, or cloud provider APIs (GCP, OCI, Nebius).
  • Familiarity with Linux containers and container orchestration (Docker Swarm, Nomad).
  • Comfort working across the stack — Python backend and TypeScript/React frontend.
  • Experience with developer tools or CLIs (bonus: SkyPilot or similar frameworks).
  • Proficiency with infrastructure-as-code (Terraform, Kustomize) or observability tooling (Grafana, Prometheus).
  • Background in real-time systems: SSE, WebSockets, or event-driven architectures.
  • Prior experience at a startup where you wore multiple hats and shipped across domains.

Benefits

  • Health, dental, and vision coverage for you and your dependents
  • 401k Plan with 4% company match
  • 21 days of PTO & 14 company holidays; including 2 floating holidays
