Senior Go Backend Engineer

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.
