On Call Nomad Developer Jobs (NOW HIRING)

Job Summary:
Mithril is an AI infrastructure platform focused on making GPU compute more accessible and affordable. The Software Engineer - Member of Technical Staff (Platform) will work across core engineering areas, owning features end-to-end and contributing to both backend systems and customer-facing surfaces.
Responsibilities:
• Build and maintain backend Python APIs powering Mithril's 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.
• 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 — so Mithril can scale supply sources without scaling headcount linearly.
• 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.
• 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.
• Participate in on-call rotations, triage production incidents, and contribute to operational runbooks and automation that reduce toil over time.
Qualifications:
Required:
• Strong Python backend skills — you've built and maintained production APIs at real scale, not just prototypes.
• 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.
Preferred:
• 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.
