We are building a distributed GPU-compute marketplace. Buyers launch GPU workloads and inference deployments. Provider nodes run workloads through a Go control plane and a Linux-based Rust agent.
We are hiring a Senior Go Backend Engineer to own correctness-critical backend systems: job lifecycle, placement, billing, provider operations, and API contracts.
You will work directly with the CTO on a system where transactional correctness matters. A duplicate request, failed worker, agent restart, or incomplete usage record must not create free compute, double-charge a buyer, or release a GPU while work is still running.
What you will own
- Go services and APIs for buyers, providers, operators, and agents.
- PostgreSQL data models, migrations, transactions, locking, and query performance.
- Job lifecycle and placement across GPU provider nodes.
- Prepaid billing, reservations, settlement, refunds, reconciliation, and audit records.
- Background workers, idempotent retries, and recovery after partial failure.
- Secure agent APIs using mTLS and signed short-lived credentials.
- Tests that prove correctness under retries, concurrent requests, and failure cases.
- Clear API contracts, OpenAPI documentation, metrics, and operational diagnostics.
Our stack
- Go backend services.
- PostgreSQL, Redis, NATS, and JetStream.
- Rust agent on Linux GPU hosts.
- Kubernetes, Prometheus, Grafana, and GCP.
- Next.js frontend.
What we need
- 5+ years of backend engineering experience.
- Strong production Go experience.
- Strong PostgreSQL experience, including transactions, indexes, migrations, and query analysis.
- Experience building distributed or event-driven systems.
- Experience designing idempotent APIs and handling retries or partial failures.
- Strong testing discipline, including integration tests.
- Experience with Redis, message queues, or NATS.
- Ability to reason clearly about correctness, security, and money movement.
- Clear written communication and ownership from design through production support.
Nice to have
- Payments, billing, ledger, marketplace, fintech, or accounting-system experience.
- Kubernetes, GCP, and production observability experience.
- mTLS, cryptography, signed credentials, or security-sensitive APIs.
- Rust, Linux, GPU infrastructure, or distributed-systems operations.
This is a hands-on senior role. You will ship production Go code, review critical changes, investigate failures, and improve the system so that it stays correct under real production conditions.
