Mithril builds electrostatically actuated antennas that give space-based radar the adaptability of a phased array at a fraction of the cost of either a phased array or a traditional deployable reflector — monitoring, scanning, and opening access to the... Backed by Techstars.
About the role
You will work across Mithril's three core engineering areas — Consumption (the developer-facing product, billing, and API surface), Platform (the orchestration and marketplace engine), and Supply (integrations with cloud providers and capacity management). You will own meaningful slices of each, shipping features end-to-end against a product that handles real revenue and business-critical customer workloads.
What they're looking for
- 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
More about this role
Mithril is an AI infrastructure platform built to make GPU compute more accessible and affordable for the world’s leading enterprises, AI startups, and the AI research community, including LG AI Research, Saronic, and the Broad Institute (among many others). Founded by a former Google DeepMind research scientist and Stanford CS PhD, Mithril has raised $80M across seed and Series A funding led by Sequoia Capital & Lightspeed Venture Partners. Platform revenue has grown >6x over the past year, and we were recently recognized by Fast Company as the 8th Most Innovative Company in Artificial Intelligence for 2026.
We are at an inflection point: transitioning from bare-metal operations to a cloud-native, multi-provider platform with a differentiated auction and flexibility model. You would be joining at the moment the platform is being built, not inherited.
